How to choose and install a fecal pump

Septic tank pump

Fecal pump for septic tank

Having your own country plot is the ultimate dream of many city dwellers, capable of bringing just as much pleasure as it does trouble. Let's take sewerage, for example. It’s good if you have built a gravity system in which wastewater moves “by itself.” But if this is impossible for one reason or another, there is nothing else left except installing a fecal pump for the septic tank. Not everyone knows what it is. Therefore, if you plan to install such a device, you need to understand in advance the principle of its operation and the main types. Especially if you choose it yourself.

Fecal pumping device

In addition to its main purpose, this sewer pumping unit is also used on the farm for other purposes. For example, in case of flooding of the basement with groundwater. Using a fecal container, the pumping of water in the collection tank is organized. If it is used for pumping out thick masses, its operation can be fully automated by installing a float switch.

Also, fecal pumps make it possible to neutralize all the consequences of natural flooding from rain, melting snow and other natural phenomena in a country house or in a private house. The pump has a shredder in its design, so if minor debris or dirt comes across, there will be no negative consequences for it.

If you have organized a storm drain on your site, then a drainage-fecal apparatus is used to pump liquid from the collector sites. This is especially effective during seasonal heavy rains. Thanks to this, there will be no problems in these engineering networks.

Such units are successfully used when servicing artificial small reservoirs; then it is better to use a submersible pump for sewage. If there is a natural reservoir nearby, then summer residents use such a pump to irrigate their plots.

Differences between a household submersible apparatus and a fecal drainage apparatus

Drainage pumps are primarily used for pumping contaminated liquids containing small particles. To prevent the penetration of solid and large elements, a mesh must be installed.

When pumping out a thick mass (for example, it could be a sewage pit), a fecal apparatus is needed. A submersible unit with cutting mechanisms will fulfill its purpose, but this requires a sufficiently powerful pump that can cope with high loads.

Pump manufacturers

There is a huge range of pumps on the market that have differences in characteristics and functions:

1.model Grundfos Sololift2 C3. The device is not equipped with a grinder, it can distill liquid with a temperature of 90 degrees above zero, and also drain wastewater from several types of plumbing fixtures at once.

2.model SFA Sanivite Silence. The device is made of materials with a high level of sound insulation - this is the main advantage of this model. The device makes much less noise during operation than similar devices. Capable of moving drains a maximum of five meters vertically, fifty meters horizontally.

3.model SFA Sanispeed. The advantages include the high power of the device, the ability to install in houses with several plumbing units. The devices can be connected to pipes with a small internal cross-section in the range of 32 to 50 millimeters.

4.model Unipump Sanivort 250. The devices have a high service life; as a rule, they are installed in small apartments. The pumps are practical to use and the housing is easy to clean.

5.model SFA Saniaccess Pump. The design does not imply the presence of knives for chopping. Used to drain wastewater from a bathtub or sink. They can briefly distill wastewater with a temperature of a maximum of seventy-five degrees.

Operating principle

Submersible

The body of the device is made of reliable, durable material that is resistant to the negative effects of aggressive wastewater.

This pump can be used both permanently and periodically, connecting as needed.

In the first case, a platform for mounting the device is made at the bottom of the container with wastewater. Pipes for pumping out fecal matter are connected to the outlet pipes.

Good to know! The disadvantage of this solution is that to service the pump attached to the bottom of the septic tank, you will have to completely pump out the pit. Moreover, taking out the installation will not be entirely pleasant.

For possible maintenance, the fecal tank can be hung on a steel cable. It will be easy to remove and repair. The submersible unit can operate without human intervention. For this purpose, the equipment is equipped with automation and a float switch.

How to make the right choice

A sewage pump for the kitchen is a fairly simple device. In some cases, you simply cannot do without it. To ensure that the operation of the pump fully justifies the investment in it and does not cause trouble, it is important to choose the right device.

• The first thing you need to pay attention to is the performance of the pump so that it can cope with the volumes you consume. The optimal value is 25 m³ per hour. This performance is quite enough for the whole family to use wastewater.
• Exhaust pipe diameter. The most common pumps have an outlet diameter of 80 mm, into which small food waste can easily pass.

Advice. The larger the outlet, the more efficient the pump will be.

• Possibility of "hot" use. When choosing a pump to connect a washing machine or dishwasher, be sure to take this characteristic into account. Cold water pumps quickly fail when pumping out hot water. Some models are equipped with a fuse that turns off the system if the temperature of the pumped waste is high.

• Method of connecting outlet pipes of consumption devices to the pump. The easiest to connect are pumps with vertical outlet pipes. In case of horizontal connection, a special adapter pipe is required.

Materials

It is important to understand that the pump for pumping out fecal matter faces an aggressive environment. Therefore, the housing elements and its parts must be reliable. Depending on the manufacturer, the sewer apparatus is made of the following materials:

• Stainless steel.
• Plastic.
• Cast iron.

Plastic is used on budget installations. A drainage pump for sewerage made of plastic is relatively fragile and does not have high power. The most expensive device is made of stainless steel. But the high price is fully compensated by the quality and long service life. Cast iron is in the middle price category.

Of the listed materials, the best is stainless steel.

Design and principle of operation

Sewage pumps for the kitchen are in most cases quite similar, the main differences lie in the functionality of the device. For example, many types of equipment differ in the presence or absence of the ability to grind solid waste.

Kitchen models in the high price category most often have a similar function. It can significantly reduce the likelihood of pipeline clogging.

The design of a sewage pump for a kitchen in most cases has the following elements:

• sealed housing (usually hard plastic) with a water reservoir;
• a membrane valve that activates and stops the system;
• electric motor with automated start function;
• holes for the entry and exit of various communications, they can be located horizontally or vertically;
• ventilation filtration valve, which prevents unpleasant odors from arising in the room and spreading throughout the house.

High quality equipment usually does not require serious maintenance. It is enough to occasionally rinse the tank and change or clean the filter. A sewage pump for a kitchen with a chopper also implies the presence of chopper knives in the design.

Operating principle: wastewater from plumbing fixtures enters a special tank. When the volume reaches a certain value, the diaphragm valve is activated and the electric motor turns on automatically. The waste is crushed and the liquid is forced to be transferred into sewer pipes. Then the level of waste water decreases, which leads to the cessation of operation of the device.

Fecal scraper with cutting mechanism

To pump out viscous masses with solid inclusions, the installation must have a grinder. There are several variations of them that are found in different installations.

1. Impeller with knives. The cutting element is fixed to the screw itself. Some may have a cast iron chopper.
2. Cylindrical scissors-knives.
3. Cross cleaver.
4. Cutter. The operating principle is reminiscent of a household kitchen meat grinder.
5. Lamellar cutters.

Each of these shredders has its own operating principle. But efficiency largely depends on the grade of steel used.

Therefore, when choosing a unit, pay attention to the cutting mechanism.

Features of choosing a pump for a septic tank

So we come to the main issue - choosing a suitable pump . Below are the main parameters that you should pay attention to when purchasing.

1. Immersion depth.
2. The diameter of the pipeline that supplies wastewater to the septic tank.
3. Distance from the point of collection to the intended installation location of the pump.
4. The maximum size of solid particles that can enter the sewer.
5. Required productivity, m³/hour. It determines at what speed the liquid needs to be pumped.

To determine the height to which the drains will rise, add to the immersion depth the length of the hose from the septic tank to the place where the water will be transported (the latter value should be divided by ten, since 10 m horizontally is equal to 1 m vertically).

Example: the pump is immersed to a depth of 6 m, the length to the waste disposal site is 15 m. We use the formula: 6 + m.

It turns out that in this case it is necessary to select a pump that can lift water by 7.5 m.

Homemade fecal apparatus

In order to save money, many home craftsmen make their own pumps. To do this you need to prepare:

1. Pump "Baby".
2. Fine mesh.
3. Metal rail.
4. Rope.
5. Welder.

The frame is made from metal slats. It is covered with an iron mesh with average cells of 10 by 10 mm. It will prevent the pump from clogging. A home-made installation can cope with impurities of 10 mm fractions without any problems. A strong rope is securely tied to the frame from above. Install the pump inside the manufactured cage.

Installation - practical advice

The installation and connection of a sewer pump in an apartment for the kitchen can be entrusted to a specialist. But, having basic plumbing skills and having studied some of the subtleties, you can do the installation yourself.

1. You can install the pressure pump in any convenient place (cabinets under the sink, niches, open areas). The water in the area from the device to the pump moves by gravity, so the outlet pipes must be located vertically or at an angle.
2. Several pumps cannot be combined into a common network. Each of them must have its own outlet to the common sewer.
3. On long sections of the outlet pipe located below the pump level, it is necessary to install an air valve to air the pipes.
4. The power supply to the pump is connected via a separate line. If the sewage pump model has a cord with a plug, the socket to it is also laid from the RCD device.

Attention! Only high-strength polypropylene pipes can be used as pump outlet pipes. The use of corrugated or cast iron pipes is unacceptable.

How to choose the right fecal agent?

Important technical information should be studied. characteristics of the device for pumping fecal and other masses.

General information

Reference! Fatty deposits and hard deposits inside the pipe narrow the space of the pipeline, its permeability decreases, so you have to clean the sewer often, and a stench can come from the pipes.

There can be two solutions to this situation:

1.redesign the room by moving the sink to a closer distance from the riser; this process is expensive.

2.apply pump installation for kitchen.

The device will ensure forced passage of wastewater into the pipes and will not allow fatty residues to be deposited on the walls.

You can also connect dishwashers and washing machines to this equipment. The device organizes rapid drainage of water into the sewer.

Such equipment can be installed both in the kitchen and in the bathroom, helping to transport liquid from all plumbing fixtures: bathtub, washbasin, bidet or toilet. When installing the device, it should be taken into account that toilet waste contains solid inclusions, so you will need to use a grinder pump.

Operating principle of the pump.

Pumps installed in the kitchen have a similar design; the devices differ in the presence of any functions. Some models have the function of grinding solid particles.

Kitchen appliances that cost more have this ability. This function reduces the risk of pipe blockages.

The sewage pump in the kitchen consists of:

1.sealed housing made of plastic material with a water tank.

2.diaphragm valve, which regulates the operation of the device.

3.electric motor, which has an automatic starting system.

4.holes for connecting communications, which are located on the body in a vertical or horizontal form.

5.ventilation valves that filter the air so that harmful odors do not spread into the room.

High-quality devices do not require frequent maintenance; it is necessary to periodically clean the tank or filter.

A pump with a grinding function includes knives for this purpose.

Reference! The grinder pump works on the principle: wastewater is poured into a reservoir to accumulate liquid. If the volume of waste rises to the maximum level, a motor is started using a diaphragm valve, which helps the knives to grind the waste. The wastewater is then forced into the sewer system. The water volume decreases and the device stops working.

Installing the device at home for a cesspool

Installation of semi-submersible

A special platform is made on the wall of the tank. The electric pump will be securely fixed on it.

Considering that its body is not airtight, a float mechanism and a water level sensor are installed. A pipe for pumping wastewater is immersed into the source. At the same time, the electric pump itself is protected from possible moisture from entering from above.

Installation of submersible

There are several ways to install a self-priming unit for a private home.

Method No. 1

1. A platform is made at the bottom of the septic tank.
2. A sewage pump is attached to the site using anchors.
3. A pipe for pumping out liquid is brought to the surface.

Method No. 2

1. A chain or steel cable is attached to the device.
2. At the same time, the electrical cable and pumping pipe are connected.
3. To pump liquid, the pump is carefully lowered along a cable and immersed in the source.
4. After pumping the sewer, the pump rises.

Surface mounting

The principle of operation of a surface fecal pump requires installation of the motor on the surface. At the same time, it is mounted on a flat and durable surface. The unit has two pipes: through one the liquid is sucked in, and through the other it is pumped out.

The secured hose or pipe is immersed into the source. If it is impossible to install the unit permanently, after completion of the work everything is disassembled and removed. If it is possible to protect the motor from rain and other atmospheric phenomena, then the system operates in stationary mode.

When is it necessary to install a kitchen pump?

If, for some reason, it is not possible to place the sink next to the riser, then the wastewater will drain away quite slowly on its own. Taking into account the fact that the composition often includes solid waste and fatty particles, after some time of operation the movement slows down even more or stops completely.

The main reason for this situation is the narrowing of the working space of the pipeline due to the deposition of fatty deposits and the formation of solid residue on the walls of the pipes. The result of this is the need for frequent sewer cleaning - see how to do hydrodynamic sewer cleaning yourself. A stench may begin to spread in the apartment and kitchen, in particular.

To avoid this situation, you can redesign the room and place the sink closer to the riser, but this is quite a troublesome and costly task. It is better to go with the second option - use auxiliary tools, for example, install a sewer pump for the kitchen.

The equipment will forcefully push waste liquids into the sewer system, this will prevent the formation of a fatty layer and deposits inside the pipe.

Also, after installing the system, it is possible to connect a washing machine and dishwasher to it. Using a sanitary pump will allow you to remove all waste liquids at the same time much faster.

However, this device can be installed not only in the kitchen, but also in the bathroom. In this room, waste liquid is removed from the washbasin, shower/bathtub, and toilet. In the latter case, the water additionally contains solid waste, so often a grinder pump is installed for the entire room.

Tips for use

In order for your household drainage pump to last as long as possible, it is important to follow several rules when servicing it:

1. Once a month, remove the pump and check it for serviceability. For example, the quality of the pipe connection, electricity, etc.
2. Check the blade mechanism from time to time.
3. Household feces can become clogged with fat deposits. Therefore, it is recommended to rinse with hot water from time to time.
4. Before lifting the pump, be sure to unplug it.
5. Check the functionality of the automation once a week.
6. Have an alternative power source, such as a generator.
7. After carrying out maintenance, be sure to check the operation of the automation.
8. Before starting the installation, clean water is connected and pumped. This will ensure that it is working correctly and correctly.

Features of operation of fecal pumps

1. Before use, rinse the device thoroughly with clean water.
2. A preventive inspection should be carried out at least once a year.
3. You need to carefully monitor the condition and level of the oil. The first inspection is carried out a week after purchase. If the oil has a grayish tint, it means water has got into it; most likely due to a defect in the shaft seal.
4. The cable entry must be sealed, without clamps or kinks.
5. If the pump clogs quickly, the chopper is worn out. This can be determined by the roundness of the cutting parts.
6. Compliance with all manufacturers' requirements, such as permissible waste temperature and others, is a prerequisite for operating a fecal pump !

Do-it-yourself installation is possible. Produced with cast iron and stainless steel body. Capable of pumping up to 260 liters per minute. The motor has a power of 0.8 kW. The kit includes automatic overheat protection. Estimated cost 13 thousand rubles.

Grundfos Liftaway

Capacity is 100 liters per minute. For surface models, a relatively powerful and reliable engine. The package includes a chopper. A clear disadvantage is the minimum mass suction height of no more than 1000 mm.

Wilo DrainLift Box

The unit is equipped with a 0.6 kW motor. Due to this, significantly high productivity, up to 300 liters are pumped per minute. There is automation in the form of a float switch. If used permanently, breakdowns may occur due to high load.

Pedrollo

This manufacturer produces both submersible and surface models. There is an impeller installed inside, on which there is a chopper. Capable of passing and processing particles with a diameter of up to 50 mm.

How are fecal pumps different?

In principle, this is the same pump for sewage. It differs in that it is capable of pumping only wastewater that does not contain solid particles. At this time, a conventional drainage pump easily operates in an environment where fine stones and other heavy impurities are found, due to which the impeller of the device can break. For this reason, drainage pumps are equipped with a special mesh filter at the inlet to trap particles that are too large.

You may be interested in information - submersible pumps for wells, how to choose

There are no filters in fecal pumps, and the maximum size of sewage effluents is limited only by the diameter of the inlet into which they enter (in most cases this is 3.5 cm or more).

Note! Most modern septic tank pumps are equipped with a float and a switch, thanks to which the operation of the device is fully automated.

Sewage pumps often do not have strainers.

We also note that this pump is often used to pump water out of basements.

How to install a submersible unit?

Let's figure out how to install the submersible unit yourself. The work is not too difficult, but it does not tolerate negligence.

Advice! The delivery package of any pumping equipment necessarily includes instructions, which must be studied before installation.

Algorithm of actions when installing a submersible pump for septic tanks:

• guides are attached to the wall of the tank, which will hold the body of the unit, and a suction pipe is installed at the bottom;
• lay outlet pipes, which must be equipped with a valve that protects against the reverse movement of liquid and a gate valve;
• an automation system is connected to the unit, setting the level at which the float should operate, starting the work;
• lower the pump to the bottom of the container;
• carry out commissioning work.

Advice! To extend the service life of the unit and prevent equipment failure due to power surges, it is necessary to connect the pump through a voltage stabilizer.

When installing septic tank pumps equipped with grinders, you must adhere to the following recommendations:

• place the equipment so that the chopper is located in front of the blades;
• the control system should be located in a place with open access;
• The pump cable must be reliably sealed and laid without kinks.

The layout of bathrooms and plumbing fixtures in country houses and cottages is always fraught with the difficulty that they must be located close to the sewer riser. Also, the pipes leading to the riser must have a slope in its direction so that the wastewater can move by gravity. Such conventions impose certain restrictions - all plumbing fixtures should be located close to each other. This problem becomes irrelevant if sewage pumps are installed. Using these pumps allows you to install a toilet, washing machine, shower and other appliances where it is convenient for you, in the basement or basement - below the location of the main sewer pipe. This is especially true for cafes, restaurants and sports clubs located in the basements of high-rise buildings. Sometimes in country houses they install fecal submersible pumps that process wastewater from the entire house and pump it into a septic tank. Such pumps differ from those described above, and in order not to make a mistake, you need to understand what each pump is intended for.

1. Types of sewage pumps
   Domestic sewage pumps
2. Industrial sewage pumps
3. Sewage pump installation
   Connecting the sewer pump to the toilet
4. Connecting a sewer pump in the kitchen
5. Installation of a sewage pump in a collection well

Types of sewage pumps

Sewage pumps can be divided into two categories: domestic and industrial. Domestic pumps are designed for pumping wastewater from one or more consumers and can be used in country houses, private small hotels, cafes, restaurants, bars, clubs and shops. Industrial sewage pumps are installed in multi-storey buildings or even in substations leading to the sewer.

Domestic sewage pumps

Sewage pumps for domestic needs differ in purpose and place where they are used, and also have design differences. For example, there are pumps that are installed directly under the water consumer, and there are pumps for forced sewerage that are installed in the well of a septic tank or sewage pumping station.

Household sewer pumps come in the following versions:

• Sewage pump for toilet (equipped with a grinder).

A pump of this type is installed directly behind the toilet no further than 40 cm and is a box approximately the size of a toilet flush cistern. The color of the pump body can be chosen so that it matches the color of the toilet and is not noticeable. The unit is connected to the drain pipe from the toilet. When the toilet flushes, it fills the pump, where metal grinder blades grind fecal matter and toilet paper. Such a pump will not cope with more serious debris, for example, a towel and personal hygiene products.

After grinding the waste, wastewater is pumped through a pipeline into the sewer riser. Typically, such toilet pumps are capable of pumping liquids up to 10 m in height and up to 100 m in the horizontal plane. After the wastewater is sent to the sewer, the toilet water seal is filled with water again.

The pipes leaving the pump can have a diameter from 18 mm to 40 mm. This allows them to be laid without harming the overall design of the room, for example, behind plasterboard sheathing or under the ceiling. Grinder pumps allow you to install toilets in any room, regardless of the location of the sewer riser, as well as below the location of the main sewer pipe. For example, this could be a basement, ground floor, redevelopment in a typical apartment and moving the bathroom to another place.

The price of such sewage pumps depends on the manufacturer. For example, the popular French pumps from Grundfos Sololift2 WC-1 and Sololift2 WC-3 cost 350 USD. and 450 USD respectively. These are reliable units that come with a warranty. In addition, in the CIS countries there is a fairly developed network of service centers that install and repair sewage pumps of this brand. Pumps from another French company, SFA (a direct competitor), are in approximately the same price range. The SFA SaniBroyeur Silence model costs, for example, 350 USD. Although they are a little cheaper, they have less power and pump to a lower height. But a pump from the Russian company Subline Service called Unipump Sanivort 600 will cost only 200 USD.

The maximum temperature of wastewater that a toilet sewer pump can pump is in the range of +35 °C – +50 °C. This is indicated in more detail in the instructions for the specific model. Also, many pumps have an additional inlet for draining from a washbasin, shower or bidet, or urinal. Therefore, water temperature is of great importance. If the water temperature is much higher, the pump may fail, although some models have protection installed that allows you to pump hot water for a short time (30 minutes), but not constantly.

In addition to toilet pumps, which are a box measuring approximately 30x45x16 cm, there are also built-in grinder pumps for wall-hung toilets. They are compact in size, thickness does not exceed 12 cm, so they are convenient to hide behind a plasterboard partition.

There are also models that combine a toilet and a pump without a flush tank. Such a device is not cheap (SFA Sanicompact 43 costs 900 – 1000 USD), but it is convenient and takes up little space. The toilet is connected directly to the water supply network and has an additional outlet for draining the washbasin.

• Sewage pump for the kitchen (without grinder).

Such pumps are also called sanitary pumps, since they pump dirty water, but are not equipped with a grinder, which means that the drained water should not contain foreign objects. Sewage pumps for the kitchen have several inlet pipes, so they can be connected to the drain from the kitchen sink, bathroom, shower and washbasin. They are installed in a cabinet under the sink or any convenient place. Pay attention to the maximum temperature of wastewater that such a pump can pump. For example, the Sololift2 D-2 model for shower, bidet and sink is designed for water with a temperature not exceeding +50 °C. This means that you cannot connect a dishwasher or washing machine to it. It is also important that kitchen pumps quickly become covered with a greasy coating from the inside and require timely cleaning.

• Sewage pump designed for temperatures above +75 °C.

This category of sewage pumps must be distinguished separately. Such units can remove hot wastewater from washing machines and dishwashers, as well as bathtubs and showers. For example, the Grundfos Sololift2 C-3 pump can be connected to a sink, dishwasher, bathtub and shower. The water temperature should not be higher than +75 °C; for a short time the pump can withstand a temperature of +90 °C. This French unit costs about 400 – 420 USD. Sewage pumps Wilo DrainLift TMP 32-0.5 EM and SFA SaniVite Silence are also designed for water at a temperature of +75 ° C and cost 350 - 400 USD.

• Submersible sewage pump.

Such pumps are also called fecal submersible pumps, and they are radically different from all those described above. Submersible pumps are installed in a well or container into which wastewater from the entire country house flows. In principle, this can be not only a country house, it can be a cafe, restaurant, club or other facility that has an autonomous sewage system. The submersible fecal pump is equipped with a powerful motor and a cutting mechanism that is capable of shredding not only feces and toilet paper, but also fabric towels, rubber gloves, feminine hygiene products, terry towels and other large items. The only thing it cannot handle is stones and metal objects, which must be avoided from getting into the drains.

After crushing foreign matter, wastewater is pumped into a septic tank, where it is treated. Submersible sewage pumps are manufactured by companies such as Grundfos, Wilo, KSB, FLYGT, HOMA and GORMAN-RUPP. The body of such a pump and the grinder are usually made of cast iron or stainless steel. The pump itself can be equipped with a float, signaling that the wastewater level has reached a point after which the pump should start pumping. In the same way, the float controls the shutdown of the unit.

For fecal sewer pumps, the price depends on the power of the unit. For example, a powerful pump PEDROLLO MC 30/50 + QES300 remote control with a power of 2200 W costs almost 1000 USD, its simpler analogue with a power of only 750 W PEDROLLO MCM 10/50 costs 350 USD. The price is also affected by the reputation and requests of the manufacturer. For example, a Ukrainian-made fecal pump DNIPRO-M will cost only 60 - 70 USD, although it has a power of 2750 W.

In addition to the above, household sewage pumps include semi-submersible pumps and pumps that are mounted “dry”. Also popular are Sewage Pumping Stations (sewage pumping stations), which are a ready-made container for wastewater in which a fecal pump of the required power is already installed. When choosing a pump for your home, be sure to read the characteristics of the unit and recommendations for its use, or better yet, consult with a specialist.

Industrial sewage pumps

Industrial sewer pumps are used in multi-storey buildings, remote sites, cottage villages and enterprises to pump wastewater into the city or autonomous sewer system. The same pumps are installed at pumping stations and wastewater treatment plants. Conventionally, industrial pumps can be divided into the following groups:

• Submersible sewage pump (sewage).

Submersible pumps are operated submerged in water at all times. Since the unit is located in an aggressive environment, its body and parts are completely made in accordance with the requirements for stability. The popularity of these types of pumps is due to the fact that they are used directly inside a sewage pumping station and do not require a special location for placement, as well as an additional pipeline.

It is also worth clarifying that submersible pumps are also suitable for “dry” installation, only in this case it is necessary to properly organize the pipe supply and pressure at the inlet pipe.

• Cantilever sewage pump.

Such pumps are installed openly in the basements of high-rise buildings, as well as in industrial sewage pumping stations. Their main difference is that the pump and motor are located separately and connected by a coupling. With proper operation, cantilever pumps can last a long time without repairs or breakdowns. If repairs are necessary, it is easy to carry out, since the pump is in plain sight.

• Self-priming sewage pump of dry installation.

Such pumps are installed in a separate room in a specially equipped place inside the sewage pumping station (sewage pumping station). They have excellent characteristics, are easy to maintain, but are quite expensive, so they are rarely used nowadays.

When choosing an industrial sewage pump, it is extremely important to choose a model from a manufacturer that can provide specialists for installation, and then deal with the accompanying diagnostics, maintenance and repairs.

Sewage pump installation

So, if there is a problem of the impossibility of moving wastewater by gravity, then there is nothing else left but to install sewage pumps. We have already considered that the scope of their application is diverse and it is necessary to select a specific model for specific tasks.

Connecting the sewer pump to the toilet

To be able to install the toilet in a place convenient for you, without being tied to the location of the sewer riser, you need to equip it with a sewer pump for the toilet. This applies not only to country houses, but also to apartments that have undergone redevelopment, as well as premises in the basement.

What pumps can be used to connect to the toilet? Grundfos pumps models Sololift2 WC-1, Sololift2 WC-3, Sololift2 CWC-3 (wall installation), Wilo pump DrainLift KH 32-0.4 EM, SFA pumps models SFA SaniTop Silence, SFA SaniBroyeur Silence, SFA SaniPRO XR Silence and others. These sewer pumps received the most flattering reviews. They are characterized as reliable and high-quality units.

Most toilet pumps have additional inlets that can be used to connect wash basins , showers , bidets and urinals . Therefore, with the help of one pump it is possible to remove wastewater from an entire bathroom.

The easiest way to connect a sewer pump to a toilet is to install a toilet with a built-in pump. You can see how this is done in the video example.

A conventional sewage pump is installed behind the toilet no further than 40 cm from it.

Tips for connecting a sewer pump to a toilet:

• Pay attention to the diameter of the inlet pipe on the pump. It must match the outlet of the sewer drain pipe from the toilet (toilet bowl outlet). If the diameter of these holes is different, the installation will be incorrect.
• Before installing the sewage pump, read the instructions carefully. Most often, it is equipped with all the necessary diagrams and recommendations, and the pump itself includes everything necessary, right down to the mounting screws.

• The first step is to insert connecting elbows or supply pipes into the inlet pipes.
• Then install the pump behind the toilet and secure it to the floor with screws. On the pump body there are special cast lugs with holes for such fastening.
• All pipes supplying the pump should be located with a slope of 3 cm by 1 m, ensuring the movement of wastewater by gravity.

• Then the outlet sewer pipe is connected to the outlet hole. What recommendations exist for its location are indicated in the photo example (dependence of pressure on the height and length of the pipeline).

• If the sewer pump model requires ventilation, then it is necessary to install the ventilation duct above the ridge of the roof of the house. Although there are models with a carbon filter that ensure the absence of unpleasant odors in the house.
• The pump is connected to the electrical network through a 30 mA RCD. If the pump model is supplied with a ready-made plug, then it can be connected to a personal socket, the cable to which must be routed directly from the panel and the RCD.
• All bends of outlet and inlet pipes must be smooth.
• All pipeline connections must be made by soldering, welding or adhesive joints.
• If there is a need to drain wastewater in a vertical plane, then the vertical section of the discharge pipe must be made no further than 30 cm from the outlet of the pump. This will ensure normal pressure in the pipeline.

Please note that the toilet sewer pump cannot be installed below floor level or in pits. Only next to the toilet, ensuring easy access to the pump for maintenance and repair. To prevent the water that the pump removes from returning, a check valve must be installed at the outlet pipe.

Connecting a sewer pump in the kitchen

If you plan to install a dishwasher or washing machine in the kitchen, then you must select a sewage pump that is resistant to high temperatures - up to +90 °C. The following models are suitable: Grundfos Sololift2 C-3, Wilo DrainLift TMP 32-0.5 EM and SFA SaniVite Silence. There are also more powerful models with a storage tank that can handle large volumes of wastewater from all appliances in the kitchen.

You can install a sewer pump in the kitchen anywhere - in a cabinet under the sink, near a wall, in a closet or other convenient place. The main thing is to calculate everything so that all supply pipes are located with a sufficient slope (3 cm per 1 m) and are not too long. Otherwise you will have to use several pumps.

Tips for connecting a sewer pump for the kitchen:

• If several pressure sewer pumps are used, they must have individual entrances to a common riser or main. Connecting the outlet pipes from the pumps into one is prohibited.
• If the outlet pipe from the pump has an extended horizontal section, which is located below the pump level, then at the highest point it is necessary to install a valve (0.7 bar) to ensure air access after the pump is turned off.
• If the pump model requires air cooling of the electrical circuit, then a special plastic tube will be included with the pump, which must be inserted into a special hole in the housing and brought out vertically 50 - 80 cm above the pump. This will ensure a flow of air to cool the electrical circuits.

The outlet pipe from the pump must be made of hard plastic, such as polypropylene or polyethylene. Flexible corrugation cannot be used in pressure sewers.

Installation of a sewage pump in a collection well

A fecal pump is used to process and pump wastewater into a septic tank. In cases where it is impossible for wastewater to flow directly from the house into the septic tank, for example, if it is located far away, a collection well is installed next to the house, into which a sewage pump is installed. Sewage from the entire house flows into a collection well, where a pump crushes it and pumps it further into a septic tank for purification.

Also, installing a collection well is possible if the central sewer system is located at a distance and it is necessary to create a pressure capable of directing wastewater directly into it.

The most convenient option is to purchase and install a Sewage Pumping Station ( Sewage Pumping Station ). It is a plastic container of various volumes and shapes, the material of which is resistant to aggressive environments. The container is completely sealed and there is practically no danger of leaks. A fecal pump is installed inside the tank, which processes garbage and wastewater and pumps it further. Most often such pumps are submersible.

It is necessary to dig a pit of the required depth under the container. Only the hatch should remain on top. The bottom of the pit should be compacted, and then a concrete pad should be placed on top. To do this, crushed stone and sand are added, and then concrete is poured in a layer of 10 - 15 cm. After the concrete has hardened - after about a week - a sewerage station can be installed. It must be lowered carefully. The pump station must be strictly level - vertical.

The pump is connected strictly according to the instructions. For this purpose, a cable and chain are provided to lower and raise the pump. The outlet pipeline must be made with high quality by soldering or welding.

Then the KNS container must be filled with water, this will make it possible to sprinkle around the container. As the container is filled with water, the outside walls of the pump station can be filled with sand to the very top. The last 15 - 20 cm can be laid with turf. After fixing the pump station in the pit, the water can be drained.

Installing a sewer pump with your own hands is not a difficult task, but only if you strictly follow the instructions and do not make compromises. For example, you cannot install a sewage pump for a toilet in a collection well or connect a pump with a temperature limit of +35 °C to a washing machine. Detailed instructions are provided directly for connecting the pump. If suddenly you cannot figure it out on your own, do not take risks, seek help from professionals.

Pumping heavily contaminated media

When installing sewer systems in a house, it is not always possible to lay pipes with the required slope. It may be necessary to install plumbing fixtures at a lower level than the entrance to the riser (for example, in the basement) or at a considerable distance from the riser.

In such cases, a submersible fecal pump with a grinder for the septic tank is used. This equipment is equipped with a cutting mechanism that shreds large debris before it is further transported.

Well cleaning

To make the process of cleaning the well as simple as possible, it is recommended to purchase a special float with which the water level will be determined. Despite the fact that this type of device operates in automatic mode, it is advisable to monitor the process of its operation. It consists of the following steps:

• Effluent pumping.
• Destruction of growths of moss, silt and other contaminants present at the bottom of the tank.
• Cleaning the filter.

On average, cleaning a well takes 1-2 weeks.

Scope of application of a well drainage pump

Drainage pumps are multifunctional, therefore, they have gained wide popularity in many areas. They are used to supply water to private houses and to water gardens from wells on the territory of a country house. Basically, they are used for:

1. Pumping water from tanks. Very often they are used to pump liquid from various reservoirs or pools. There are special models that are equipped with a float switch, which regulates the pump’s actions and turns it off when a certain water level is reached;
2. In many cases, it can be used for watering gardens and other areas. This saves time and money, which is why these devices are in great demand among summer residents, farmers and rural residents;
3. Dewatering of construction sites or pumping water from pits under buildings in the first stages of construction work. Later they can be used to supply water for domestic purposes and mix solutions;
4. Pumping water from flooded basements , storerooms, garages and other premises;
5. Acceleration of oxidative processes and purification of water bodies.

Installing a pump to remove dirty water

When using a pump to pump out water from basements or other premises, it is recommended to provide a backup power supply. During a power outage, backup power will provide the pump with power to pump out water.

Technical specifications

Household sewer pumping units have the following technical parameters:

• power. This is the main value on which the remaining capabilities of the device depend;
• height of liquid rise. Measured in meters, it shows to what height a given pump can supply wastewater;
• pipeline length. This value determines the length of the pipes with a slight slope towards the pump;
• wastewater temperature. For domestic installations this is an important value as the wastewater can be very hot. There are models with a temperature limit of up to +45°, there are more stable ones with an operating value of up to +85°;
• number of receiving pipes. Powerful models have 2 or 3 of them, low-power units have only one inlet and supply pipes;
• availability of additional components and devices. These include shredders and filters for removing odors.

When purchasing, compare the parameters of the pumping unit and the features of the drainage system. First of all, they determine the power of the device, then consider other indicators.

Cleaning a well using a drain pump

When purchasing pumps for cleaning wells, you need to carefully read the instructions for use, because many models are designed only for pumping clean water. In addition, there are pumps that only handle water that contains contaminants and small inclusions.

Cleaning the well will be easier if there is a float that floats on the surface of the water. While when operating the pump without operating this float it is necessary to maintain continuous monitoring, if it is present, the pump will automatically turn off when pumping water is completed. If you do not turn off the pump in time, its motor may overheat and become faulty, because water cools the pump

Cleaning a well with a drainage pump

To reduce the noise level emitted during pump operation, you can use a flexible rubber adapter between the pump and the outlet pipe. This will also increase its service life.

The procedure itself is quite simple, but it is very important to adhere to the following rules:

1. First, the pump must be immersed in depth , not reaching the bottom 0.5 m;
2. The pump turns on , after which the well begins to be cleaned of contaminants;
3. The pump must be lifted regularly and its filter cleaned until sludge forms on it.
