Replacing a gas tap in an apartment is a very responsible and dangerous procedure. In accordance with current regulations, it must be carried out by specialists with the necessary experience, knowledge and equipment. However, this is not always possible; sometimes you have to change the gas tap in the apartment yourself. To do this efficiently and safely, you need to know how to choose the right new device or repair an old one, and most importantly, the regulations for carrying out work on the gas pipeline.
At whose expense are the gas taps and hoses in the apartment replaced?
They scare old people with fines and offer their services at exorbitant prices.
Scammers force people to pay exorbitant prices for servicing their stoves. Marina VOLOSEVICH Change text size:AA Last week, the State Housing Inspectorate warned: from this year, owners of gas stoves and water heaters will face serious fines. They can be discharged for the lack of a contract for the maintenance of the stove and water heater, as well as for not allowing a gas service employee into the apartment.
The other day there was a knock on the door of Lyudmila Sandalova (name changed) from Chelyabinsk. Two men resolutely walked into the kitchen and began to shame the pensioner: “It’s time to change the tap, we’re writing you an order.” The replacement deadline is a month. The work costs a thousand rubles.

Question No. 33297 Question author: Vladimir.
N 491) reads: “...5.
The common property includes in-house engineering systems of cold and hot water supply and gas supply, consisting of risers, branches from the risers to the first shut-off device located on the branches from the risers, the said shut-off devices, collective (common house) cold and hot water metering devices, first shut-off devices - control valves
Hello, Oleg! No, you are not required to change the gas shut-off valve.
Since the gas shut-off valve does not belong to the in-house gas equipment, but to the general house gas equipment, the responsibility for its proper operation and replacement, if necessary, lies with the management company, and not you.
Letter from the Ministry of Regional Development of Russia dated October 18, 2013.
In accordance with paragraphs four and seven of clause 2 of the Rules, indoor gas equipment in an apartment building includes gas pipelines, which are the common property of the owners of the premises, laid from the gas source (when using liquefied petroleum gas)
Maintenance
The service life of the stoves is finite, and using the equipment beyond the norm is dangerous, so regular maintenance must be carried out. Of course, the lion's share of responsibility falls on the owners of gas domestic installations. The final service life of the stove depends on them, because it can fail much earlier than the specified time if you handle it carelessly. The owner of an apartment where a gas stove is installed is obliged to ensure:
- The operation of the burners is correct.
- The tightness of the oven closure.
- The integrity of the gas hose connecting the installation with the liquid fuel supply pipe.
- The performance of the gas leakage protection system.
Within the limits of the warranty established by the documents, the owner conducts visual inspections of the equipment and, in case of the slightest malfunction, must call a technician.
After the expiration date, maintenance should be performed once a year. Based on its results, the technician gives an opinion on the possibility of further using the gas stove or replacing it.
Who does the maintenance?
Before the collapse of the USSR, maintenance of gas equipment was a mandatory measure, which was assigned to mechanics of gas distribution organizations.
The cost of their work was included in the price of utilities, and therefore there were no problems with maintenance. But the new economic era has made significant adjustments in all areas; periodic inspection and repair of installations was excluded from the price of household gas. Until 2008, there was complete confusion in this area; many companies appeared that were not responsible for either the professionalism of their staff or the quality of service. If you have any questions, you can consult for free via chat with a lawyer at the bottom of the screen or call by phone (consultation is free), we work around the clock.
The adopted legislative acts helped change the situation:
- Decree of the Government of the Russian Federation No. 549 of July 21, 2008, which approved the “Rules for the supply of gas to meet the household needs of citizens.”
- Order of the Ministry of Regional Development of the Russian Federation No. 239 dated June 26, 2009 on the “Procedure for the maintenance of repairs of in-house gas equipment.”
These documents established that the consumer bears all responsibility for operation and timely repairs. He is responsible for concluding agreements with organizations specializing in this problem, which will provide in-house gas services and emergency dispatch support. Agreements must be concluded at the stage of connecting the household to gas networks. According to legal regulations, maintenance responsibilities are assigned to organizations with certified specialists on staff who have sufficient knowledge to eliminate any problems that arise.
Gas equipment inspections
Maintenance of gas equipment is carried out in accordance with the approved Decree of the Government of the Russian Federation, List of VDGO dated May 14, 2013 No. 410. It includes the following mandatory work:
- Visual inspection to determine the integrity of the slab and other components.
- Checking the tightness of connecting parts and disconnecting equipment.
- Lubrication of fasteners, valves, taps and other mechanisms.
- Establishing the functionality of a shut-off device that allows you to shut off the gas supply if the permissible parameters are exceeded.
- Cleaning burners from dirt.
- Gas supply adjustment.
The technician must check not only the stove, but also the smoke and ventilation ducts. And if there are cylinder installations, the tightness of the connections is inspected and the gas supply pressure is checked. Mandatory oral instructions to the consumer are provided.
When are gas taps replaced?
A gas valve is a shut-off valve on a gas riser. Since the valve is a moving mechanism, it tends to wear out and become unusable. Manifestations of this can be various signs: jamming, excessive rotation, the appearance of a strong smell of gas. However, only a gas service specialist can reliably determine whether the gas tap in the house needs to be replaced, based on the results of a visual inspection and maintenance.
If you have identified such signs during operation, invite a technician for unscheduled maintenance. Scheduled inspections are carried out annually, so if there are signs of malfunction, the technician or master will identify them independently.
To replace gas equipment, he has only three reasons (clause 10 of the Rules, approved by Government Decree No. 410 of May 14, 2013):
- The end of the service life established by the project or manufacturer. For valves, such deadlines are usually not established; if they are in good technical condition, they are used indefinitely.
- Determining a valve malfunction and recognizing it as unsuitable for repair based on the results of maintenance.
- Submission of an application for replacement by the owner of the equipment. Yes, you can change the faucet on your own initiative.

Regulations and rules of work
Current legislation states that only employees of the gas supply company have the right to repair gas communications. To determine the scope of work, a preliminary check is carried out. The technicians visit all apartments, inspect communications and make notes regarding the level of wear of networks and locking elements. Based on this information, a decision is made regarding the purchase of materials and the upcoming scope of work.
When visiting the site, the team is provided with an order sheet, which clearly indicates the list of planned activities. All masters carry company employee identification cards with a photograph and a hologram.
The work is carried out at public expense in accordance with current regulatory requirements. Old pipes are removed and heavy-duty new ones are installed in their place. They are selected depending on the pressure level in the city network. At the same time, all shut-off valves are changed. There is no charge to residents for this.
Equipment malfunction
Any durable goods may break during use. Not all breakdowns require replacement of the gas stove; they can simply be repaired. But device owners must clearly understand the main rule - any detected malfunctions are extremely dangerous and can create an emergency situation. If there is a gas leak, breakdowns can lead to fatal consequences, not only for the owner himself, but also for other people and premises. Each gas stove manufacturer has its own weak points. Frequent malfunctions during operation are:
- Failure of gas burners. They may not turn on at all or the auto-ignition may not work.
- The burner stops working during operation, the fire goes out due to the flame jumping through, and the gas continues to flow.
- The gas supply is so weak that it is impossible to light the burner.
- The flame smokes and burns unevenly.
- The valves regulating the gas supply do not work well - they do not turn or slip.
- There is no pressure on the oven or it is so low that it is impossible to light the burner.
- After releasing the valve, the flame goes out.
- There is a smell of gas.
In all cases, making repairs yourself is prohibited. Before the technician arrives, you should turn off the general gas supply valve and ventilate the room so that gas does not accumulate if it leaks.
Relocating a gas pipe: procedure
It is strictly prohibited to move gas pipes on your own; such work is carried out only after agreement with the relevant government organizations. The transfer is carried out by specialists with the required qualifications. Without permission, you can only move the slab slightly to the side (no more than 0.4 m), if it is connected by a flexible outlet.
Without permission, you can only move the slab slightly to the right or left
Obtaining permission to move the pipe
The procedure is as follows:
- First of all, the owner of the premises should contact the gas supply organization at the place of residence (Gorgaz), where they fill out a standard application about the need to carry out work to replace or relocate gas pipes to connect the stove. It is necessary to indicate what exactly needs to be changed and for what reason.
- The application left will be the basis for calling a representative of the gas service. The date of the visit is usually agreed upon immediately. The arriving technical specialist carefully inspects the premises, listens to all wishes, studies the provided project and assesses the possibility of its implementation taking into account all technical standards. If necessary, adjustments and changes are made or other options are provided.
- After approval of the final transfer scheme, the organization providing the services draws up estimate documentation for the work being carried out.
- The drawn up estimate must be agreed upon with the owner of the property, who must give his consent.
- Upon receipt of all documentation, payment is made.
- Within 5 days after payment of funds, gas workers arrive at the work site and carry out the transfer of gas pipes according to the developed plan.
To ensure that the process of moving gas pipelines does not drag on for an indefinite period of time, it is necessary to carry out a number of preparatory measures:
- Meet with gas masters in person or call them by phone and find out what additional materials will be required. Everything should be purchased and prepared in advance. As a rule, workers bring all pipes and fittings with them, since their cost is included in the estimate. But flexible hoses for connecting gas appliances are purchased separately.
- Excess equipment and furniture must be removed from the premises, ensuring unhindered access to all elements of the gas system.
- If dismantling is impossible, you need to protect all valuables with burlap, plastic film, tarpaulin, etc. This is necessary since the upcoming activity is accompanied by increased dust formation.
Video: redevelopment of gas equipment
Gas pipe transfer technology
The process of transferring gas pipelines consists of the following sequential actions:
- Immediately after the technicians arrive and immediately before starting work, it is necessary to turn off the gas supply using a valve.
- The remaining gas must be vented through the stove or heating boiler, and the pipe must be purged to remove debris and dust.
- Using a grinder or welding, cut off the unnecessary pipeline fragments according to the adopted plan.
- Close the resulting hole with a special plug or weld it.
- Make a new hole for the gas outlet in another place in the pipeline.
- Mount and weld a new metal pipe element to the hole made, following the design.
- Cut a thread at the free end of the welded outlet and install the tap using sealants (FUM tape, tow, etc.).
- Connect the necessary gas equipment using a flexible hose.
Our neighbor undertook to move the gas pipes in the house himself. He believed that after the fact he could very easily legitimize everything. But it turned out to be much more difficult than he thought. At first he was obliged to dismantle everything, then draw up a project and start again. Through a long walk through various authorities and payment of a decent amount, we managed to resolve this issue. As a result, the rework was much more expensive.
Step-by-step instructions for replacing the valve
The procedure for replacing the gas supply valve to the device is quite simple, but extremely responsible, since natural fuel is flammable, and when combined with air, it is an explosive substance. Therefore, we strongly recommend that you seek the help of specialists who have been trained and have received permission to carry out such work.
Having installation skills and following safety rules, you can install a crane yourself in just 15-20 minutes - but only in case of urgent need. In the future, the result should be monitored by a representative of the city gas company.
To replace a tap on a pipe you will need the following tools and materials:
- new locking mechanism to match the pipe;
- two gas wrenches No. 1 or No. 2, one of which will be needed to unscrew the thread, the second - to hold the lower pipe motionless (this will avoid damage to the pipeline leading to the gas stove);
- a means intended for sealing the place where the faucet is attached to the pipe (for this purpose you can use ordinary linen thread, FUM tape, Tangit Unilok thread);
- flat screwdriver;
- graphite grease, grease or other lubricants;
- plug for a 0.5-inch pipe with internal thread (when working together, you can do without this element).
If the threads or diameters of the pipes and the tap do not match, extensions, fittings, and adapters may also be needed.
The replacement process consists of a series of simple operations that must be performed as quickly as possible to minimize gas leakage from the system. First of all, you should shut off the supply of natural fuel to the apartment by placing the valve handle in a position perpendicular to the pipe.
When replacing the gas shut-off mechanism, the valve is tightened by hand, only the last turns are made using a wrench
After this, you can begin to dismantle the old tap, which is unscrewed from the pipeline. If the process is difficult to carry out, you can try treating the threaded connection with WD-40, which improves smoothness.
If a welded valve was previously installed in the room, it will have to be cut off using a grinder, after which additional threads should be cut on the pipes. A temporary plug is placed in place of the removed valve.
Before treating the connection between the tap and the pipe with sealant or FUM tape, this area should be thoroughly cleaned of dirt and corrosion.
A thread is wound onto the thread for sealing. To do this, unscrew about 7 cm of thread and place it in the outermost recess of the thread, then wind the thread clockwise into each groove.
Having covered the thread with one layer of thread, you should continue winding in the opposite direction. After this, the laid insulation is covered with a layer of graphite lubricant or other suitable composition.
If linen thread is used as a thread sealant, it should be treated with oil paint. When using Tangit Unilok thread, such an operation is not required
The plug is removed and a new tap is quickly placed in this place (it is important to make sure that its handle is in the “closed” position). The element is screwed on manually, the last turns are made with a wrench.
DIY faucet replacement
To replace the tap with your own hands, you need a tool (gas wrench), a gas tap and FUM tape (you can also use special compounds to seal threaded connections). All of the above can be purchased in specialized stores or construction department stores. It is more convenient to replace the gas tap with an assistant.
It should be noted: the gas pipeline has relatively low pressure (unlike, for example, a water supply). Based on this, there is no need to shut off the entire gas network. However, safety measures still need to be taken. First of all, the window must be open when carrying out work. The doors to the kitchen should be tightly closed, and the cracks should be plugged with rags or towels.
We begin the work by dismantling the used gas tap. We remove it using a gas wrench. As soon as the faucet is removed, we plug the pipe with a thumb pad. At this time, the assistant screws FUM tape onto the new faucet or applies sealant to the threaded connection.
When everything is ready, carefully, but without wasting time, connect the gas tap to the pipe. Before screwing in the new faucet, you need to make sure that it is in the “closed” position.
Next you need to make sure the connection is tight. To do this, use the old proven method with a soap solution. A soapy solution should be applied to the connection and if bubbles appear, the connection will leak. The defect must be corrected immediately: remove the tap and repeat sealing the connection.
At the end of the work, you should thoroughly ventilate the kitchen area and connect the gas stove to the system. Even in the absence of professional skills, the operation to replace a gas tap takes no more than 15 minutes. The advantage of doing the work yourself is significant cost savings. However, if you do not have confidence in your own abilities, it is better to entrust this work to specialists from the gas supplier’s service department.
Types of gas taps
There are many types of shut-off devices that are installed on gas pipes. Based on the features of their designs, two main groups can be distinguished:
Variety #1: cork
Until recently, this was the most common type of gas tap. The central part of such models is a conical element (plug) with a hole.
The main body of a plug valve is a cone-shaped insert with a hole in the middle. With its help, the gas flow is blocked or opened. The taps are made of brass or cast iron - durable, wear- and corrosion-resistant materials (+)
When opening the device using a flywheel, the hole in the conical part is aligned with the same one in the pipe, allowing gas to pass to the equipment. A gland is usually used to connect plug valves to the pipeline to create a seal.
Variety #2: ball
The main part of this type of locking element is a spherical part made of strong metal. As in its cork counterparts, it has a hole, which, when turning the handle, is aligned with the pipe, thereby ensuring access of natural fuel to the corresponding device.
Diagram of the operation of a ball valve: the main operating element of such a device is a round part that blocks the gas admission in the closed state and ensures the passage of flow in the open state
Such valves appeared relatively recently and quickly gained popularity due to their many advantages, namely:
- low cost;
- excellent functionality and safety margin;
- long service life;
- ease of operation;
- ability to work in various environments at temperatures from -60 to +80o C.
Due to the combination of valuable qualities, experts now give preference to spherical structures when equipping household gas systems.
Unlike coupling and flange models, which can be used repeatedly, a welded valve is a disposable device and cannot be repaired
According to the method of connection to pipes, there are several subtypes of ball valves:
- Threaded (coupling). In this case, the tap is connected to a section of the gas pipeline using a threaded part.
- Flanged . Fastening is carried out using flanges fixed with bolts. Such devices are most often used when transporting gaseous substances and oil.
- Welded . In this case, the tap is firmly welded to the pipe using an appropriate apparatus.
According to their purpose, ball valves are divided into three types:
- Three-way, used for redistribution of gas flows;
- With a heated body, used in cold climates;
- With leakage control.
There is also a division according to the diameter of the passage.
According to this indicator, details can be classified into two categories:
- DN 10-50 mm;
- DN more than 50 mm.
Another classification takes into account the nominal pressure that the valve can withstand.
In this case, there are two types of devices:
- PN 1.6 MPa 16 kg/cm2;
- PN 4.0 MPa 40 kg/cm2.
Ball valves can be made from different types of metal. The most widely used elements are those made from brass, zinc, steel 20 and alloys (09G2S, 12Х18Н10Т), plastic.
The best qualities are demonstrated by brass devices, which can have a yellow or silver color (the latter is typical for nickel-plated models). Devices made from this alloy can be recognized by their relatively heavy weight.
Gas taps made of brass or bronze are recognized as the most wear-resistant and resistant to external influences. This device is characterized by its small size, reliability, ease of use, and high service life.
Featuring a robust, versatile design, brass taps are durable, low maintenance and can be installed in any position.
Replacement, verification or repair - which is more profitable?
If it is discovered that the meter is faulty, it is reasonable to ask the question: is it worth sending the device for repair or verification, or is it easier to immediately buy a new one?
Also, repair or verification makes sense if the meter is expensive. In this case, the money spent on its repair or verification may be much more modest than its complete replacement. Some meter models installed in private homes can cost around 10–15 thousand rubles.
To submit a gas meter for verification, you need to pay for dismantling and installation - about 690 and 580 rubles, respectively. For verification you will have to pay on average about 500 - 700 rubles.
Thus, checking the meter along with removing and installing a gas meter costs approximately 1,900 rubles. Also in many cities there are companies offering to check the meter at home, this will help significantly save time, but will cost from 3,000 to 5,000 rubles.
If it turns out that the meter is broken, you will need to look at the cost of repairs and draw conclusions about purchasing a new device based on this.
And even gas company employees will not always be able to replace the battery. Often you will have to send the metering device to the factory where it was manufactured, or to a specialized service, which will take a lot of time and cost about 500 rubles.
The price of a new meter for an apartment is around 2,000 rubles. This is how much the most popular models Grand-1.6 and SGMB-1.6 cost. A meter for a private house, type VK-G6, costs about 4,000 rubles. Replacing the meter costs around 880 rubles.
Based on these data, it can be calculated that installing a new meter for an apartment will cost 2880 rubles, and for a private house 4880. Verifying the meter costs 1900 rubles, plus the meter will not be in the apartment for some time. This means that all this time, gas consumption will be taken into account according to standards that are significantly higher than actual gas consumption.
Verifying the meter in a private house is justified, while the difference between verification and installing a new one in an apartment is not so big, and many people prefer to simply install a new one.
Repairing the apartment meter does not look profitable at all.
Procedure for calling specialists
The best choice is not to carry out manipulations yourself, but to call Gorgaz employees.
The procedure in this case is as follows:
- You need to contact the company servicing your home, tell them in detail about the problem and leave a request to call a specialist (before his visit, it is better to refrain from using gas).
- At the appointed time, the company’s employees will come to the apartment, perform diagnostics and decide whether to replace the faucet. They will also tell you which valve model you can purchase yourself or suggest using the option they have.
- Since Gorgaz specialists may ask to see a gas supply contract, documents for a gas stove, or the last paid gas bills, it is better to prepare them in advance.
- Before the workers’ visit, it is also advisable to light blue fuel and let it burn out in the pipe by turning off its supply with a tap at the gas meter. Such an operation will help save time, since all manipulations can be carried out only after the pipeline is empty.
- It is also necessary to ventilate the room well, creating a draft.
- When gas workers carry out work, it is advisable to be close to them in order to monitor their work.
- After replacing the device, you should check it with the repairmen by testing the burner.
- Specialists fill out a report on the operation performed, certifying it with the seal of the service organization. The owner of the apartment also signs the paper.
- After all work is completed, the windows should be left open for at least another half hour to allow all the gas to escape from the room.
In case of planned work to replace or repair gas systems, the service of dismantling the old locking mechanism and installing a new model of faucet is performed free of charge, however, the apartment owner purchases the device, as well as consumables, at his own expense.
Faucet replacement services are usually performed by a repair team of two people, so the procedure takes a minimum of time
When calling specialists, you will also have to pay a small amount for the service provided and pay for the device.
Relocation of a gas boiler in an apartment, approval
- internal gas distribution is an open system, all covering elements are camouflage in nature and should not be firmly fixed;
- It is prohibited to lay pipelines through ventilation ducts, as well as doors and windows;
- metal structures are predominantly used; flexible connections are allowed in equipment connection areas, but their length should not exceed 3 m;
- a rigid method of connecting pipes and hoses to pipes is used;
- Pipe transitions through walls/partitions are equipped with special adapters - sleeves.
For a long period of time, it maintains tightness and elasticity even under active mechanical stress. The structure of the shell is preserved even under high pressure of the transported medium or under constant mechanical stress.
Types of gas flexible hoses
The current market offers a fairly extensive list of gas hoses. In addition to the material, you will also need to choose a manufacturer. And in this case it is better not to save. The item is bought once and for a long time. Having saved 500 rubles, you can then spend a lot on health and repairs if the pipe starts leaking gas. Therefore, let’s first look at the varieties.
Rubber-fabric
It has many advantages that allow it to be used in a gas system:
- easy installation;
- good flexibility;
- low cost;
- various sizes;
- excellent electrical insulation.
The disadvantage of such rubber parts is poor rigidity. Today, the industry produces hoses from a special material of high elasticity. Therefore, their service life can reach 10 years.
The cost of such hoses usually does not exceed $7.
Bellows metal
Professional gas fitters consider it the most suitable for gas systems. The service life of such hoses can be more than 25 years. It connects to a gas stove without any difficulty. Bellows systems can be connected to boilers and water heaters, and they are completely safe.
If you have a gas stove equipped with electric ignition in your kitchen, in order to connect the bellows device, a special insulating connection is created between it and the tap.
This type of hose bends freely and can withstand high pressure, reaching 6 atmospheres. It can withstand significant temperature changes ranging from -50 degrees to heating up to 200 degrees. The main disadvantage of a bellows hose is its cost. It is many times higher than similar gas connections.
The advantages of such bellows metal systems include:
- made of stainless steel;
- complies with GOST;
- meets all technical requirements;
- protected from any mechanical influences by a special polymer coating;
- able to withstand any mechanical impact;
- the warranty period exceeds 30 years;
- withstands voltage of 1500 Volts.
Oxygen
It can also be connected to gas stoves, but you need to take into account several very important points:
- The internal diameter must exceed 16 millimeters;
- The surface in contact with oxygen must be well cleaned of oil. Otherwise, the hose will overheat and material damage will occur.
The advantages of oxygen hoses include the following characteristics:
- withstands high pressure. It can reach 20 atmospheres;
- very simple installation;
- low cost;
- rich assortment;
- does not conduct electric current.
Replacing a pipe with a hose
In Soviet times, gas stoves were connected using steel pipes to the gas pipeline by welding. Today, such a design is impractical and during major repairs, employees will replace the old pipe with a flexible hose. This device allows you to move the stove to a convenient distance when carrying out independent repair work inside the apartment.
Several types of flexible hoses can be used to connect the slab:
- made of rubber and fabric;
- made of rubber braided with metal;
- bellows metal hose.
A flexible connection will allow you to move the stove to the required distance.
The last option is considered the most common - it is strong and reliable. It is a metal in a corrugated shell that can bend. The pipe is cut off to avoid static charge using a dielectric insert between the tap and the hose. The stove is connected to the hose, then the metal mesh included in the kit is inserted - it protects the burner from contamination. Both ends of the hose are tightened with a wrench. At the final stage, a safety check occurs using a soap emulsion.
Conclusions and useful video on the topic
The video shows in detail the process of replacing the tap on the pipe leading to the gas stove:
Replacing a faucet is a simple but very important process. Even if you have experience in carrying out similar work, according to the standards, you cannot do it yourself - you need to contact specialized services. There are employees who have been trained and received the necessary permission to carry out repairs of gas systems.
Please write comments in the block below. I'm interested in stories about how the valve on your gas line was replaced. Ask questions, share your impressions of the information we provide, post photos related to the topic of the article.
What is needed to change the stove?
So, you are about to change the stove. What you need to prepare for this:
- The stove itself, in the case where you do not have the preferential status necessary for a free replacement. The device must comply with GOST 33998 and have a gas control system.
- Equipment for installation, necessary tools, consumables and materials.
- Equipment - everything for sealing, flexible hoses and so on.
- Documents for redevelopment if the kitchen is moved to another location.
- Documents confirming the authority of the owner or tenant of the apartment.
- Identification.
- Consent of all apartment owners.
- All papers on gas supply.
- Technical passport of the apartment.
Again, if the location for the device remains the same and only the device itself is replaced with a similar one, there is no need to legalize the conversion.
If you are changing a gas stove to an electric one, you must legalize the conversion; if you are moving the appliance to another room, then the redevelopment. If you are simply replacing it with a similar one, you do not need to carry out any approvals on both points.
The requirements for a new stove are standard. It must have all the necessary certificates and meet the requirements of GOST.
It is also recommended to check whether there will be free access to it and the gas pipeline in case of redevelopment, whether the chimney is in working order, and whether the ventilation is functioning as required.
Checking the results of the actions performed
After completing all manipulations to replace the locking mechanism, it is necessary to check the tightness of the connections created. To do this, it is enough to use a proven method: dilute soap with water and apply the resulting emulsion to the place where the valve fits on the threads, as well as on the plug. If the joints are not connected tightly enough, bubbles will be observed in places where gas leaks.
In addition to the traditional test with a soap solution, you can also use a special device that allows you to detect the presence of natural gas in the room
In this case, the defect must be corrected immediately. To do this, remove the tap and repeat all the operations again, trying to wind the thread and apply the sealant more carefully and accurately.
How to move a gas boiler or water heater to another location
It is necessary to draw up, coordinate and approve the relevant technical documentation, which is difficult. In practice, you will have to dismantle, clean and remake (digest) the supply gas pipeline, lead it into the room where the new project requires installing a boiler or water heater.
You can’t just pick up and move a boiler or gas heater to another room. The gas connection to the devices is usually done with a flexible connection, which is a corrugated stainless steel tube, the so-called “gas pipe”. In this regard, there is a clause in the regulations that does not allow the flexible gas supply to cross any structures, windows, doors or other openings.

Sources of danger
There are, in fact, only two of them.
The fact is that independent work related to opening the gas pipeline will inevitably lead to a gas leak.
- At a certain concentration of natural gas or propane-butane mixture in the air, it will become unbreathable.
- Long before this, the gas-air mixture will become explosive. The slightest spark when turning on an electrical appliance, triggering any relay (for example, a convector thermostat) or clicking a light switch will lead to exactly the consequences that we tried to warn the reader against in the first section of the article.
The rules that will help avoid negative consequences are quite obvious.
- All work is carried out with windows wide open throughout the entire apartment or house. Yes, yes, regardless of the time of year. Don’t be afraid that your favorite cactus will freeze: if everything goes well, forced ventilation will last no more than 10 minutes.
- The room must be completely de-energized. What the instructions relate to is, I think, clear from the previous explanation. Take it seriously: as already mentioned, the cost of a mistake can be the highest.
Gas equipment should not be touched outside the apartment. Even if it is located on the street.
Conclusion
Currently, gas ball valves are widely used in domestic and industrial gas pipelines. This is due to the fact that they are reliable and durable. The only thing is, when choosing which gas tap is better, you should give preference to more expensive devices from well-known manufacturers, since cheap products may not meet the required quality.

Safety Rules and Tips
You must adhere not only to the step-by-step instructions, but also to the requirements for a secure connection, which include the following recommendations:
- The connections and flexible hose make them accessible in case of a sudden gas leak.
- The maximum permissible length of 1.5 m cannot be exceeded by a centimeter.
- Twisting, bending, pressing, and contact with hard surfaces is not allowed.
- Normal use is permitted only after inspection by a gas service inspector.
- Before starting work, stop the gas supply and check that the valve is sealed in the closed position.
- During the installation process, only special equipment, fasteners, tools, and seals are used.
- The use of uncertified components and sealing materials is prohibited.
- After depressurization, the pipes are plugged with a damp cloth and released immediately before connection.
- For half-inch pipes, a regular cap from a PET plastic bottle is used as a stopper.
After assembly, each connection is coated with a soapy water solution to detect leaks. Bubbles indicate that the connection needs to be unscrewed, the seal removed, a new one applied and re-twisted. After this, the verification procedure is repeated. At the end of the activities, the tap is turned off, and a master from Gorgaz is called, who must carry out an inspection and make a corresponding note in the log. Even if you have to wait several days for an inspection, do not use the oven as it is unsafe even if everything is done correctly. Only a specialist will identify a defective slab if the manufacturer allowed it.
Gas stove service life
The shelf life of gas stoves for household use is determined by GOST.
In Soviet times, it was established by GOST 10798-85. This standard stated that the average operating time of this equipment was considered to be 4 years. These standards were revised in 1994, when the new GOST R 50696-94 was issued. The developers of the new document analyzed information about the operation of modern gas equipment and its wear rate and increased the service life several times. The working time was increased to 14 years. In 2006, the document was again revised and finalized, as a result of which the new GOST R 50696-2006 was born. He, unlike the previous ones, does not prescribe the final service life, because they depend not on how many years the stove stood after purchase, but also on how often it was used. On average, this equipment lasts 20 years. There are established standards for determining the final service life of each individual slab based on external features.
Analysis of typical installation errors
Although the operation of replacing a gas tap is quite simple, it can end in failure for inexperienced craftsmen.
If the length of the old faucet does not correspond to the same parameter of the new one, you should use extensions, which can have internal and external threads
Typical shortcomings are:
- Inability to connect the tap to the pipe. Most often this happens due to the fact that these elements do not match in size or thread. Adapters and extensions of different shapes and sizes will help correct the situation. To avoid getting into a similar situation, it is advisable to take into account the parameters of the pipes at the stage of selecting a tap.
- Valve not tightened enough. The threads must be tightened by hand, but a wrench must be used at the end. If this is not done, the connection will not be reliable enough, which will lead to gas leakage and instability of the structure.
- Tightening the tap exclusively with a wrench. When working with a tool, the possibility of damage to the part or thread breakage increases.
- Insufficient tightness of the connection. If testing the replaced faucet shows that natural gas is being released into the air, you should immediately turn off the stove and correct the error as described above.
Do not use faucets of poor quality
In order for the equipment to serve for a long time, it is important to choose models from well-known companies. It is advisable to use brass devices that require a minimum of maintenance with maximum efficiency and durability
Silicone and other similar materials dry out and lose their elasticity, as a result of which they begin to leak gas. To prevent this from happening, it is better to use graphite-based lubricants.
Let's get started
Tools
What should you prepare before opening a gas pipeline?
- We have already mentioned a pair of gas keys . Precisely a pair - because in most apartments of the old building, the supply to the stove is made of rigid pipes; To unscrew the locknut and coupling, you need to hold the drive in a stationary position, not allowing it to turn the valve.
- To seal gas threads, FUM tape or synthetic thread with Tangit Unilok sealant can be used . Linen with paint is also suitable, but the paint takes a relatively long time to apply to the threads and winding, and in our case, seconds will count.
- When repairing a tap, a special graphite lubricant for gas taps or regular grease can be used . The graphite base is more practical: it retains its properties longer.
- In addition, when repairing the valve, you will need a 1/2-inch female plug and a flathead screwdriver..
If you are looking for something to lubricate a gas tap on a stove, pay attention to specialized graphite lubricants.
Audit
So, what to do if the gas tap smells like gas and replacing it is not in your plans?
- We close the valve by turning its handle perpendicular to the pipe.
- We use one of the gas keys to fix the outlet after the valve and then hold it in a stationary position.
- Using the second wrench, we tighten the locknut and coupling onto the long thread of the drive.
- We partially unscrew the valve with a key until it starts to rotate by hand.
- We completely unscrew the valve and immediately attach a plug to the thread. Do not be afraid that excess pressure will interfere with you: it is only 3 - 5% higher than atmospheric pressure.
- We wind the thread under the plug and tighten it by hand until the end.
- We unscrew the valve from the surge.
Don't forget to remove layers of old winding and paint.
- We unscrew the plug with a groove for a screwdriver on the back side of the valve and remove the spring hidden under it; then we push the conical plug out of the body.
- We clean the body and plug from the remnants of the old lubricant and apply a thick layer of new one.
- Reassemble the valve in reverse order.
- We put it in place of the plug, not forgetting to replace the thread winding.
- We screw in the drive and, having re-winded the threads, we drive the coupling and locknut into the working position.
Replacement
What to do if the gas tap in the kitchen is leaking and you want to replace it with a new one?
If the new valve is the same length as the old one, the actions are completely similar to those described above - with the difference that manipulations with the plug are, for obvious reasons, made unnecessary.
The valve is turned until it stops by hand, then about 1 turn with a key.
How to change a gas tap in an apartment if its length does not match the length of the old one?
- The drive with the coupling and locknut is thrown out.
- The short thread after the drive is equipped with a short extension with internal and external threads. This will allow the union nut to press the gasket against the smooth, wide edge of the extension rather than against the jagged end of the pipe.
The photo shows extensions for threads.
- The valve and extension are connected by a male-female gas hose. Of course, with sealing of all threads.
A special case
How to change the tap on a gas cylinder if it cannot be opened with a regular key? Heat the valve with a hair dryer - and its expansion will make the force required to unscrew it quite feasible.
Important: valve replacement is performed with an empty cylinder.
How much does it cost to replace a gas meter?
According to the decree of the Russian government, replacement of the gas meter is carried out at the expense of the homeowner. This is because all the equipment in your home belongs to you. This means that operating costs fall on your shoulders.
This fact is established not only for owners of private houses. Art. 158 of the Housing Code of the Russian Federation clearly states that the owner of an apartment in an apartment building bears all costs for maintaining the premises.
So you will have to pay:
- purchasing a gas meter;
- the work of specialists in removing the gas meter and installing a jumper pipe;
- cost of services for verification and repair of the device;
- services for direct gas meter replacement.
The cost of meter replacement services will be determined by specialists on site. The price depends on the complexity of the work, the number of devices, the length of the pipe for the gas meter output, as well as on the region of residence and the tariffs of the organization.
On average, you will have to pay about 15 thousand rubles for the device, and for services to replace the gas meter no more than 7 thousand rubles.
All listed expenses apply to owners of private houses and apartments. If your home belongs to the municipality, then they must bear all the costs of replacing the gas meter.
Areas of responsibility
The first and main thing that the reader should pay attention to is that the inlet valve in the apartment falls under the responsibility of GorGaz or a similar organization operating in the area where you live. Both the repair and replacement of valves, and their periodic inspection, and the connection of gas equipment (stoves, boilers, convectors, hobs) should be handled by the mechanics of this organization.
Once again: you carry out all actions with gas equipment at your own peril and risk. The consequences of mistakes can be the most severe: a household gas explosion is perhaps the most terrible event in an apartment building, often turning it into a heap of construction waste. If you have even the slightest doubt about your ability to complete all the work, and to do it quickly and correctly, invite a specialist.
If:
- you have quite a lot of experience in locksmith work; in particular, you have had to change valves and valves under pressure;
- you know where the power is cut off in your apartment, and you have access to the switchboard and the machines in it;
- the gas pipe in front of your valve has no visible signs of corrosion;
- at your disposal are plumbing tools (at least two gas wrenches No. 1 and/or No. 2), sealing material for threads and grease or graphite lubricant -
the following text will help you replace or repair the gas stove tap yourself.
Consequences of a domestic gas explosion.
How to choose an inlet tap for an apartment
I will definitely devote a separate article to this issue, here it is briefly
Understanding the importance of the purpose of inlet valves, for the correct choice there should be only one criterion - reliability
Therefore, exclude valves made of zinc-aluminum alloy (TSAM or ZAMAK) from your choice. It is often called silumin, but this is not true, although silumin is even worse than TsAM.
Give preference to stamped brass valves with ball lock (ball valves). Don't buy valves. They are cheaper, but wear out faster. The water from the riser has not yet been cleaned by mud collectors, so the valve valve quickly wears out, although it can be repaired.
Manufacturers
Gas pipelines are one of the most critical housing systems. Therefore, special attention must be paid to the selection of all its elements, including shut-off valves.
It is advisable to purchase products only from well-known, well-established manufacturers.
In particular, you can give preference to cranes from such Italian companies as:
- Bugatti;
- FIV;
- Valtec;
Italian crane from Valtec
In addition, products from the following companies are of good quality:
- Dungs - Germany;
- Profactor - Germany;
- Broen Ballomax – Poland;
- Efar – Poland;
- LD – Russia.
Advice! You should not buy the cheapest gas valve, since there are a lot of low-quality fittings from China on the market, which do not always meet all the requirements for gas shut-off valves.
Design
There are several types of gas bellows. Its simplest type is a banal corrugated sleeve. A more advanced version uses a protective surface made of corrosion-resistant steel. There is also an option with a polymer coating. The most reliable design includes thermal safety valves that automatically cut off gas flow if the temperature exceeds a set limit.
The bellows is more expensive than any other option used to supply gas in domestic conditions. There is nothing surprising in this, because this design is designed for maximum pressure. It is made from stainless steel hose.
Most often, AISI 316 steel is used for the hose. Since the fittings must be stronger, metal of the AISI 303 or 304 categories is used for them. Individual companies, mainly Chinese and Turkish, supply fittings made of carbon alloys. But it is advisable to use components made from the same substance. When welding dissimilar metals, electrochemical corrosion is provoked, as a result of which the weld, despite all the skill of the performers, will quickly collapse.
When does the slab need to be replaced?
Not all damage can be repaired with permission for further use. Today it is not uncommon for a technician to arrive and end up with a complete ban on using the existing gas stove. Such regulations cause a lot of controversy as to whether it can be said that the equipment is not subject to further use only on the basis that its shelf life has come to an end. In some apartments, people stay extremely rarely, and accordingly, they use the stove to a limited extent. There are two main criteria by which the unsuitability of gas household equipment is determined:
- Oven burnout. If a through hole of any size appears in one of the places, then the entire installation is considered unusable.
- There is a leak in one of the four gas supply valves to the burner. For each crane, the limit is considered to be 11,000 operating cycles. If one of the burners stops working due to critical tap exhaust, then the stove is also considered unsuitable for further use.
If you have any questions, you can consult for free via chat with a lawyer at the bottom of the screen or call by phone (consultation is free), we work around the clock.
Wanting to avoid unnecessary problems, craftsmen often issue an act banning the use of a gas stove, without any factual basis, relying solely on the established warranty periods.
Although this approach is very controversial, not everyone is able to challenge it. Even if the installation was purchased and stood in its packaging for 20 years without functioning for a day, it may well be considered unusable and prohibited from use.
What you need to know: valuable tips
Before purchasing a flexible hose, it is necessary to check the size of the thread at the outlet of the plate, its classification and whether it is straight or angular. If the outlet is of a direct type (directed into the wall), you must purchase a sleeve with a square at the end.
The gas hose should not be painted - this will accelerate its cracking. A more attractive look can be created by covering it with special paper or oilcloth.
It is also strictly forbidden to tightly seal gas communications with false plasterboard panels and other structures - this will make it difficult to carry out service work on individual elements.
To camouflage the gas supply system, a collapsible box is used, which can be easily dismantled if necessary. In this case, there will be constant access to all structural elements of the gas system.
It is forbidden to use unnecessary connections. Independent complication of a gas structure, according to technical regulations, may entail a fine or disconnection from gas supply
If a technician has been called to connect a gas water heater or stove, it is necessary to check that the work is being done correctly: the excess tap from the tap on the lower side must be unscrewed, the flexible line must be directly connected exclusively to the tap located on the branch pipe, and its other end - only to the outlet of the gas stove .
It is also possible to use an adapter. Any additional installations are prohibited.
Key points for selecting a device
When choosing a locking mechanism for a gas pipeline, you should pay attention to the following characteristics:
- Pipe diameter. The tap must completely block the flow of gas into the apartment. If the shut-off element does not fit tightly to the walls of the gas pipe, then its tightness will be only partial, which can lead to serious consequences.
- Coincidence of diameter and thread pitch on the pipe and tap. In this case, installation of the device is quite easy. Installing a locking element with mismatched threads and diameters is, in principle, possible using adapters, but this will require additional material and time costs for the purchase and installation of additional parts.
- Hull integrity. The outer shell of the element must be free of cracks, chips, sagging and other defects. Their presence indicates a violation of the rules for transportation, manufacturing or storage of parts, which can lead to internal malfunctions, as well as a reduction in the service life.
You should also pay attention to the quality of the products, giving preference to models from well-known companies.
Installation of dielectric insert
Many of us, at least once, having touched a gas stove, suddenly felt a weak, but very noticeable electric discharge. It would seem, what does electricity have to do with it, since the stove is gas? However, not all so simple.
In fact, there can be two reasons for the appearance of an electric discharge. The first is the application of a small negative electrical potential to the main pipes to protect them from electrochemical corrosion. Of course, at the junction of the main pipe with the section leading to the house, a dielectric insert must be installed, which isolates the apartment wiring from the main.
However, such protection works as long as the insert is in good condition. If the insulating insert fails, an electric current appears on the flexible line from the riser to the slab. The second possible reason is the use of electrical components in the gas stove. Almost all modern models of gas stoves are equipped with electrical appliances - from electric ignition of burners and oven lighting to an electric grill that rotates a spit in the oven. If the insulation of the electrical wiring of the stove is in order, there will be no problems. But if the insulation is damaged, an electric current will flow through the supply line - now from the stove to the riser.
Whatever the reason, the consequences of the above-described phenomenon can be extremely dangerous - the current flowing through the liner, especially when using sleeves in a braid, which is made from wire of a small cross-section and, therefore, has a high resistance, can heat up the sleeve braid so much that it simply burns the existing Inside there is a rubber hose. In this case, a gas leak will inevitably occur, which, in contact with the heated braid, can easily ignite or even explode. By the way, this is why metal-braided rubber hoses are not recommended for permanent connection of household gas appliances.
To avoid these troubles, it is enough to use a special dielectric insert when installing the liner. Typically, such an insert is made of plastic or combined materials (for example, the insert itself is plastic, and the threaded parts are metal).
Insulating insert: on the left - plastic with metal thread, on the right - plastic
Our company’s specialists are always ready to install the dielectric insert for you. GazService-NN specialists will carefully, quickly and efficiently install the dielectric insert. At the same time, you do not have to purchase it yourself; we will always have all the necessary consumables, including dielectric inserts for gas.
By entrusting the work to “GazService-NN”, you will not have to worry about the consequences of poor-quality installation, because we are a specialized service company for the installation and maintenance of gas equipment and have all the necessary documents to carry out this type of work. If necessary, we will also replace other elements of the gas system and inexpensively install or replace any gas equipment in your apartment or house.
Selection of gas valves
If a malfunction is detected in the operation of the gas valve, it is recommended to replace the device as soon as possible. First of all, you need to select a new valve. When choosing, experts recommend considering:
- type of valve;
- basic device parameters.
Kinds
The gas pipe valve can be:
cork. The body of the plug valve contains a conical element driven by a flywheel. There is a hole in the conical element (plug), which, when combined with a hole in the pipe, allows gas to flow to the equipment. The seal acts as a sealing material that seals the connection between the faucet and the pipes;
Sectional view of a cork valve
spherical The design of a ball-type gas valve differs from a plug valve in that the locking mechanism is based on a ball made of durable metal. The ball has a hole, which, when the flywheel is turned, is located along the gas pipeline and in this way passes gas to the consumer.
- Gas pipeline valve with ball locking mechanism
- Experts recommend using ball valves for domestic gas pipelines, as they are more reliable.
- According to the method of connection to pipes, a household ball valve can be:
- threaded The valve is connected to the gas pipeline pipes with a threaded connection;
- Valve installed with threaded connection
- flanged. The connection to the pipes is made using flanges, which in turn are fixed with bolts;
Gas valve fixed with flanges
welded, that is, installed using a welding machine.
Gas valve installed by welding
Threaded and flanged valves are reusable, that is, if necessary, you can remove the device from the gas pipe, check its functionality, carry out repairs and install it in its original place. The welded valve can only be installed once.
Basic selection parameters
To select a gas shut-off valve, it is recommended to pay attention to the following factors:
- pipeline diameter. The shut-off element of the valve must completely block the pipe in the apartment. If the valve is larger or smaller, the tightness of the tap will not be complete;
- pitch and diameter of the thread on the pipeline. To quickly replace the device, it is necessary that the specified parameters completely match. Otherwise, you will need to purchase and install additional adapters;
- the material from which the gas pipeline valve is made. It is more advisable to purchase brass taps, as they have a longer service life. You can also find silumin, zinc and plastic taps on sale. You can distinguish the material used to make the valve by weight. Brass faucets are heavier than faucets made from other materials. In addition, you can inspect the place where the thread is cut. Brass has a yellow tint, and all other materials (except plastic) are gray;
Gas valve made of nickel plated brass
- The valve body must be free of chips, sagging, cracks and other defects. The presence of these factors indicates non-compliance with the rules for manufacturing the product, which will lead to a reduction in service life;
- It is more advisable to purchase valves from well-known manufacturers. For example, you can choose cranes manufactured by Bugatti (Italy), Dungs (Germany), Broen Ballomax (Poland).
Following simple rules when choosing a gas valve will allow you to choose a reliable device with a long service life.
Gas valve installation
Preparatory stage
To change the gas valve in the kitchen yourself, you need to prepare:
- new tap;
- two gas keys. One wrench is required to unscrew the threads, and the second to hold the down tube stationary. Otherwise, the pipeline leading directly to the gas stove may be damaged;
- means for sealing threaded connections. FUM tape, Tangit Unilok thread or regular linen thread are suitable. When using linen thread, additional treatment of the sealing material with paint is necessary;
Special thread for sealing threaded connections
graphite lubricant intended for gas valves;
Special composition for gas appliances
pipe plug. If you replace the valve together, you can do without using a plug.
Replacement process
The gas valve is replaced according to the following scheme:
- the gas supply to the living space is cut off. To do this, the gas valve handle is turned to a position perpendicular to the pipe;
Gas valve in closed position
- the valve is unscrewed from the pipe. If you cannot unscrew the thread, it is recommended to treat the threaded connection with WD-40, which will ensure smooth operation. If a welded valve is installed in the apartment, then it is cut off using a grinder, and threads are cut on the pipes;
- A temporary plug is installed in place of the valve. If the work of replacing the gas valve is carried out by two people, then instead of the plug you can use your partner’s finger. This procedure will facilitate the process of installing a new faucet;
- a sealing thread is screwed onto the thread;
Winding flax thread to make the threaded connection tight
- a layer of graphite lubricant is applied on top of the thread;
Final preparation of threads for valve installation
- A new faucet is being installed.
When working indoors, it is recommended to open windows and turn off all electrical appliances. These actions will lead to maximum safety.
The process of replacing a gas valve yourself is presented in the video.
Leak test
After installing the gas valve, it is recommended to check the tightness of the device and the resulting connections. For this:
- open the tap and start supplying gas to the stove;
- prepare a saturated soap solution, which is applied to the tap and connection points.
Finding gas leaks using a soap solution
If the device and threads allow gas to pass through, small soap bubbles will form at the leakage site. If a leak is detected, the problem must be corrected quickly.
- Doing the job of replacing a gas valve yourself is risky.
- Any careless action or violation of safety regulations may result in an explosion. Therefore, it is recommended that replacement be carried out by qualified personnel.

Refusal to replace the gas meter
Replacing and installing a gas meter is voluntary for every owner. Payment for gas upon consumption is always less than the average tariffs set by the management company.
Many owners of private houses and apartments receive notifications that the device needs to be checked and replaced, and they strive to quickly submit an application.
However, this should not be done for several reasons:
- perhaps the notice was sent not by the organization servicing the house, but by a third-party company that has nothing to do with the control of gas equipment, but simply seeks to sell its services;
- The time frame for checking or replacing the device has not yet arrived. To establish the exact date of the warranty period of the gas meter, it is necessary to check the certificate and manufacturing date of the device;
- the owner does not need to replace the meter and wants to abandon it.
The latter option sometimes also arises, despite the fact that it is cheaper to pay for gas with a meter. As a rule, such cases arise if the deadline has come, but the owner is selling his home and does not want to spend money on replacing equipment.
Sealing of modern gas meters occurs using special plastic blanks and does not take much time
It is also worth refusing a replacement if the apartment is transferred from the category “with gas service” to the tariff “with stationary electric stoves”. Typically, such transitions are made in Khrushchev-type apartments, when the gas supply to the apartment is completely stopped and additional capacity for electric stoves is installed.
The owner needs to know that neither the management company, nor the HOA, nor any other organization can force him to install a gas meter in his apartment.
Examination
After any work, make sure there are no gas leaks. Checking is also necessary if the gas tap in the kitchen sometimes leaks and you cannot determine the exact location of the leak. The algorithm of actions is extremely simple: a soap solution is applied to all threads with a shaving brush; The leak will make itself known by swelling bubbles.
Like that.
