Rimless toilet: pros and cons, popular models and installation

The first samples of rimless toilets appeared in 2002. Japanese was the first to present customers with its concept of this type of plumbing.
The attractive appearance and hygiene of this design were appreciated by customers. Following the example of Japanese plumbing manufacturers, European companies also began producing rimless toilets. In 2007, the English company organized the supply of innovative plumbing equipment to hospitals and other public institutions. Following her example, Keramag began producing stylish and hygienic toilets.

Customer reviews of the new product are mostly positive, and existing problems are more likely related to violations of manufacturing technology, rather than to design flaws. Almost all reviews note high hygiene and ease of maintenance. Based on statements from customers and experts, a rating of the most popular models is regularly compiled.

Unique design

Modern interior designers know well what a rimless toilet is (rimless, rimfree). This is a new, more hygienic type of plumbing. The unique feature of this design is that it does not have a rim. The purpose of the rim is to direct water from the drain tank so that it washes the entire bowl and quickly removes impurities. But it has a significant drawback - microbes accumulate on its lower part and rust occurs, so the toilet must be washed regularly with a disinfectant. Dirt accumulated on the rim can cause a persistent bad odor in the toilet. It can be extremely difficult to get rid of it. Cleaning takes a lot of time and effort, and a rimless toilet requires less labor-intensive maintenance.

Many housewives have made their choice in favor of rimless toilets, and for those who are just looking at plumbing fixtures, it is advisable to find out the pros and cons of the models in advance. This will allow you to make an informed decision and choose the appropriate design.

Rimless toilet: advantages

• Hygiene. Rimless toilets are easier to keep clean. Standard models have protrusions under which dangerous bacteria multiply. The new generation toilets are a monolithic structure without hard-to-reach places.
• Economical. A vertical circular flush in older models uses up to 10 liters of water at a time, while a directional flush in a rimless toilet requires only 2–6 liters.
• Aesthetics. The streamlined shape of the bowl looks sleeker and makes the bathroom interior more modern.

What is the difference between a rimless design and a regular one?

Rimless toilets first appeared in 2002. They were produced by the Japanese company TOTO. The differences between a non-standard model without a rim and a regular one are manifested in appearance, as well as in the flushing process. The developers came up with a fundamentally different way to flush water. The liquid should clean the entire inner surface of the bowl, but not splash all over the bathroom. There were several solutions for this:

• a ceramic divider divides the flow into three directions: along the sides and along the back;
• a small depression in the rear upper part of the bowl prevents water from “overflowing its banks”;
• Flow separator channels distribute the liquid into many small and weak jets.

There is no single universal design for rimless toilets. Developers are constantly experimenting and coming up with new solutions.

Monoblock toilets: description

Such plumbing fixtures appeared on the market relatively recently, but are already very popular. This is due to the fact that they do not have connecting elements, which means that the possibility of liquid leakage is excluded. Such solidity of the product is achieved even at the production stage in the factory. There, after assembling and installing each component element, the entire monoblock is tested, its compliance with GOST requirements is determined, and only then it is sent for sale.

Although these products perform the same functions as ordinary toilets, they differ in undeniable advantages and conveniences. At the same time, the specifics of a monolithic toilet are different. In appearance, monoblocks are similar to their “brothers”; they also use a floor installation and the same drain tank. But unlike compact toilets, a monolithic toilet is equipped with a water intake and release device, which are located in a one-piece frame.

A monolithic toilet is considered a reliable and durable plumbing structure, since it does not have components connected through rubber gaskets, which are likely to cause leaks. Dimensions of monoblocks vary from manufacturer to manufacturer. This remark most likely applies to manufacturers from abroad, since in our country they are all regulated by GOST No. 30493-96.

How the device works

What does a rimless toilet mean and how does it work? The principle of operation depends on additional parts that reduce the flow power.

How to flush a rimless toilet:

• With a ceramic divider, water diverges in three directions (side and back walls) and washes the entire bowl.
• With channels around the entire circumference - the liquid flows in thin streams, but manages to wash the entire inner surface.
• With a recess - the hole from which the water flow comes out is low. The recess prevents water from splashing and splashing.

These technologies allow water to come out from several points simultaneously. The streams flow almost horizontally. Non-standard designs do not affect the cost of rimless models. Additional costs may only be required when installing the toilet to the wall.

Some rimless toilets are equipped with a water flow reducer - a hydraulic throttle placed in the pipe between the flush cistern and the bowl. This device reduces the speed and force of water pressure. The liquid does not splash out of the bowl when flushing, but the flush itself becomes less powerful.

Many rimless structures have an installation system. The flush tank is located 30 cm higher than in a conventional toilet. This allows the liquid to flow vertically, which means increasing the force of water pressure when flushing.

Production leaders in the monoblock segment

The leading position in the ranking of monoblock manufacturers is quite rightly occupied by the Italian company Laguraty . The line of this brand includes models of laconic and luxurious design, made in a non-trivial and classic style.

It is this company that offers original options with tanks in the shape of a soccer ball or a flower vase. Bathroom equipment from designer Giovanni Laguarti is produced in Italy and China.

The parent company strictly monitors the quality of products supplied to the market by Chinese structures, because bears overall responsibility for the serial production of products bearing the specified brand logo.

Naturally, a product produced by Italian enterprises will cost significantly more than a Chinese-made equivalent. Note that the second option is not inferior in quality to the first, so it makes no sense to overpay for a purely Italian product.

Proven technologies are used in the production of Laguraty monoblocks. The company's patented casting and firing processes guarantee long service life of about 25 years. The production uses exclusively natural raw materials that do not pose a threat to the environment.

Plumbing faience is coated with a heavy-duty glaze that prevents contamination and wear. The package includes a durable plastic seat with a micro-lift that gently lowers the lid onto the bowl.

The Laguraty assortment includes modifications with horizontal and vertical drainage, which allows you to select plumbing fixtures for any sewerage installation scheme.

There is a half shelf around the circumference of the bowl against the splash; the design of the circular drain eliminates the appearance and spread of bacteria on the sanitaryware.

Royalking Sanitary Ware SSWW , whose production plants are localized in Germany, is no less actively involved in the production and supply of monoblocks to the market

Unlike the Italian brand described above, the German company does not specialize in the production of monoblock sanitary ware, but devotes enough space to it in its assortment.

Solid monoblock structures of the SSWW brand are covered on both sides with a dirt-proof glazed nano shell, which prevents surface contamination, rust deposition and limescale deposits.

Firing of sanitary ware blanks is carried out using our own technology. The monoblock tanks are equipped with unique fittings from Geberit and seats with microlifts.

Water for flushing comes from holes located around the circumference of the bowl. There are two modes of water consumption for flushing, providing an opportunity to save water consumption.

An interesting and practical new product is offered to customers by the Spanish manufacturer Roca . A new word in his developments is a monoblock toilet combined with a washbasin.

In addition to the stylish design and impressive shape of the ROCA W+W 893020001 , the aspect of water saving has been carefully thought out. A model created on a similar principle is in the Laguraty line of monoblocks, its serial number is 8074. The monolithic design tank has two compartments, one of which is designed to collect water drained from the sink.

The second compartment of the tank is directly connected to the water supply, so that there are no difficulties with flushing if the volume in the first section of the tank is insufficient.

The excellent design of the monoblock system is solidly complemented by high quality characteristics, the stability of the plumbing and the strength of the material.

By analogy with other representatives of the segment, the toilet is equipped with an ergonomic seat with a microlift. Combining three separate objects into a monoblock provides the opportunity to significantly increase the free space in the bathroom.

Gustavsberg is replenishing the market with very worthy monoblock plumbing fixtures , guaranteeing impeccable product service for a quarter of a century, although it does not please with an affordable price.

Olympia and Turkish sanitary ware from VitrA are in demand . Both manufacturers guarantee the use of monoblocks without problems for at least 10 years.

A warranty period of 5 years for bowls and 3 years for fittings is promised by Arcus (China), which produces a wide range of monoblock toilets. The assortment includes products in numerous shades of white, colored, black models and monoblocks with elegant painting.

Products of this brand are attractive due to their affordable price and the company’s diligent desire to maintain high world-class quality standards.

There are smart toilets on sale that are made using a monoblock principle. Multifunctional smart plumbing is equipped with systems for bidet operation, drying, and automatic lid movement. Control and configuration are carried out using a remote control.

Varieties

There are several types of rimless structures, which differ from each other only in the installation method and design.

Types of rimless toilets:

• floor;
• console (suspended);
• attached.

Each variety has its own advantages and disadvantages that must be taken into account when choosing.

Floor-standing

The floor-mounted rimfree toilet almost exactly replicates the standard model. The drain tank is installed on the rear shelf. Additionally, the kit may include a microlift and a bidet. The cost of this design is slightly lower than an attached or suspended one. When choosing, you need to consider the area of ​​the bathroom. The back shelf of a floor-mounted rimless toilet takes up 15–30 cm from the floor and wall, so such models are not suitable for small apartments. If the bathroom is too crowded, you should give preference to other models.

Another disadvantage of a floor-mounted rimless toilet is that the flush cistern is too low. In combination with dividers and dividing channels, the water flow in this design has very low power, so flushing may not be effective enough. It is advisable to choose floor-standing models with a high cistern location: the higher it is, the cleaner the toilet will flush.

Console (suspended)

An original design solution will be a toilet that seems to “float” in the air. Hanging sanitary ware allows you to save space in the restroom and visually expands the space in it. The interior looks unusual and stylish, you can feel good taste in the design of the apartment.

A toilet attached to the wall seems very fragile, although it can withstand a weight of up to 500 kg. They are mounted very firmly, so they do not lead to leaks.

The main advantage of a wall-hung rimless toilet is its ease and simplicity of cleaning. It is enough to wipe the inside of the bowl once with a clean brush. You can do without cleaning products.

But this design is not without its drawbacks:

• installation complexity;
• bowl not deep enough;
• inability to operate the anti-splash system;
• high price of both the model itself and its installation;
• The drain tank and flush button are located in a hard-to-reach, unclear place.

These disadvantages are easily compensated by positive qualities, which are manifested in the way a rimless console-type toilet flushes. In a model with a high tank, the water flow is distributed rationally and competently, therefore the overall water consumption is reduced. This allows you to save not only water, but also money for utilities. This toilet flushes very quietly.

Attached

These models combine the advantages of console and floor-mounted toilets. Attached structures are a universal type, ideal for all bathrooms.

Advantages:

• wash off cleanly and effectively;
• work quietly;
• water consumption is small;
• easy to install;
• deep bowl with anti-splash function;
• The flush tank can be hidden on the wall.

The disadvantage of an attached rimless toilet is the high price. In addition, this model makes access to communications difficult. Such designs are not always available on the market; you have to specially order them from the manufacturer, and then call plumbers to install the device in the bathroom.

Before purchasing, you need to carefully study all the pros and cons of each rimless toilet model. It is necessary to take into account the area of ​​the toilet room, the cost of construction and installation, the quality of the flush, the height of the tank, the depth of the bowl, and also understand how much water a particular flush model uses. Some toilets are equipped with motion sensors and light signals that allow a person to navigate in the dark.

Disadvantages of rimless toilets:

• due to the low tank, the bowl may not be cleaned properly;
• high cost of the structure and its installation;
• Many people feel uncomfortable sitting on a toilet with a shallow bowl;
• When flushing, water often splashes out of the shallow bowl;
• deposits of mineral salts collect on the inner walls of the bowl, which need to be cleaned, otherwise they will distort the direction of the jets when flushed;
• Bacteria can accumulate in the toilet drainage channel, so this area must be thoroughly cleaned.

Most of the shortcomings are due to shortcomings of plumbing manufacturers or manufacturing defects.

By carefully studying the pros and cons of different rimless toilets, the buyer will be able to purchase a suitable design.

Advantages and disadvantages

The undeniable advantages of such plumbing include ease of cleaning and hygiene of the bowl. In addition, the price of such toilets, especially those with floor mounting, differs slightly from bowls with a guide rim. This is due to the fact that the complexity of manufacturing the rim practically compensates for the installation of a ceramic divider and the increase in the cost of drain systems.

There were no significant shortcomings in the use of this type of bowl by consumers, with the exception of outright manufacturing defects, incorrect configuration or transportation. And yet, before buying a rimless toilet, it would be useful to get acquainted with the opinions of people who have already installed rimless toilets.

An alternative solution is to glaze the rim

If it is not possible to order a ready-made rimless toilet, you can glaze all the hard-to-reach places in a regular toilet. The lower part of the rim is covered with a special substance. After glazing, bacteria and dirty particles will not accumulate in the bowl. But this is a temporary solution: under the influence of a brush and detergents, the short-lived coating is gradually destroyed. The glaze will last for several months, and then you will have to do the repairs again. Therefore, it is advisable to immediately purchase a rimless model.

History of invention

Toilets without an inner rim have appeared recently. The first European ceramic manufacturers began introducing them into widespread sale in 2013. The pioneer on the market is the English brand Twyford Bathrooms, owned by the Sanitec Group. Twyford Bathrooms introduced the first rimless toilet exclusively for the medical market in 2007. The company continued to research new design options for sanitary ware and patented an invention called Rimfree in 2012, used today by the Keramag brand.

The very first examples of toilets made using rimless technology appeared in Japan. Known for their commitment to high standards of hygiene, the Japanese have been using similar technological advances since 2002, with similar offerings produced by the Japanese brand Toto.

Today, more brands offer a new type of plumbing fixtures, for example:

• European - Duravit, Roca, Laufen Villeroy &, Boch;
• non-European - VitrA, RAK Ceramics.

Rimless models from the following companies are popular on the domestic market:

• vitra,
• cersanit,
• kolo,
• other brands.

Top brands

Many plumbing manufacturers offer rimless designs, which differ from each other in type of installation, quality and price.

Top 10 best brands:

• VitrA (Turkey) - offers Rim-ex designs with a removable ceramic liquid divider. The removable design makes it even easier to keep clean.

• Roca (Spain) - the brand offers inexpensive plumbing fixtures for public places (hotels, cafes, restaurants). The back wall of the Clean Rim bowl is equipped with several channels that divide the flow into several jets. The design is quite monotonous. We recommend choosing Inspira Round, Inspira Square and The Gap toilets.
• Gustavsberg (Switzerland) - famous for the high quality of its products. The manufacturer offers a line of Hygienic Flush toilets with Nautic, WWS and Arctic models. Floor-standing toilets from Gustavsberg are very durable, waste little water, and flush cleanly and efficiently. Due to the non-standard design, the console structures turned out to be of lower quality: they have a too shallow bowl, which requires a special brush to clean.

Am. Pm.

The company produces middle-class and luxury toilets, which are characterized by a thoughtful shape to save space. The advantages of products from this manufacturer include excellent design and comfortable operation. Manufacturing technology involves the use of only high-quality materials that fully comply with European standards.

How to choose

When preparing for such an expensive purchase, you need to weigh all the pros and cons of rimless toilets. When choosing a rimfree model, you need to pay attention to many details and nuances:

• The material from which the toilet is made. It is advisable to choose only ceramics of the highest standard. Porcelain and metal are considered the best.
• Strength. The short-lived, brittle material will quickly crack. The toilet should be free of scratches, chips, bulges and other defects.
• Uniform color and clean surface, without dirty or dark spots.
• The smooth surface prevents dirt from accumulating. You should not choose rough models, because this is an ideal place for bacteria and dirt to accumulate.
• The flushing system must work perfectly. If possible, it should be checked directly at a plumbing store.
• The method of installation and location plays an important role in choosing the appropriate option. For a small and cramped toilet, a wall-hung or wall-mounted toilet is suitable. Many are confused by the apparent fragility of the cantilever toilet: it hangs in the air and is about to fall. Therefore, many people prefer attached or floor-mounted structures. To save water and not create unnecessary noise, it is better to choose a wall-hung toilet; it has many advantages over other models.
• Additional functions - built-in cleaner, flow divider, small channels, etc. It is necessary to carefully study everything that is included in the package.
• Fastening materials (bolts, nails, screws, dowels, etc.) may or may not be included in the kit. If they are not included in the set, they must be purchased separately.

It is important to remember that the toilet bowl cannot be returned or exchanged because it is a hygiene product. It is necessary to immediately purchase a suitable model, so do not rush, but thoroughly weigh the pros and cons.

Fittings for monoblock

When choosing a specific product, you need to study its characteristics in detail, as well as the structure and quality of the plumbing monolith. The uninterrupted operation of the entire monoblock primarily depends on it. The tank fittings include a water supply mechanism and a drainage device. The drain device can be of two types: one-button and two-button tank.

It is also possible to lock the upper lever of a monolithic system, which has not a float, but a plastic cylinder that acts as a valve device. Such a lever must be raised when flushing, unlike push-button mechanisms. For example, a two-button system in monoblocks is the most economical and modern, since it allows you to regulate the drainage of water. For monoblocks, the internal design is both an advantage and a weak point.

It, like other classic toilets, may experience standard problems with water drainage. Sometimes it is not possible to repair a breakdown, and then the entire device needs to be replaced. Therefore, when choosing such a device, it is recommended to buy spare shut-off valves.

Materials

Particular attention should be paid to the materials from which toilets are made. The reliability and service life of plumbing fixtures depends on their quality.

What are toilets made of?

• Faience is ceramics whose water absorption is 9–12%. Earthenware is made from kaolin (white clay), silicates, quartz with some synthetic impurities. The concentration of white clay does not exceed 20%. The product is fired in ovens at a temperature of 1050–1280°C and then glazed. Without glazing, earthenware gradually begins to absorb odors and harmful bacteria, and then the restroom will smell bad. Nevertheless, earthenware is a very high-quality, durable and budget option.
• Porcelain is considered the best material for a toilet. This is ceramic with a water absorption percentage of 0.5–1%. The material consists of 50% white clay, to which feldspar and quartz are added. All ingredients are thoroughly crushed and mixed into a mixture of uniform consistency. The workpiece is fired in a furnace at a temperature of 1400°C. No glazing required. A porcelain toilet lasts 25–50 years.
• Semi-porcelain is ceramics with water absorption of about 5%. The composition may contain artificial impurities.

• Vitreous porcelain is a very dense ceramic with a perfectly smooth surface, which is additionally covered with a layer of enamel. Ceramics are made from raw materials that are very carefully crushed and mixed. Such models are not afraid of moisture, dirt, chemical cleaners and bacteria. They serve for more than 30 years.
• Stainless steel - has increased impact resistance. This toilet weighs only 20 kg - 30% less than a ceramic one. The inside is coated with a special substance that prevents bacteria from accumulating and multiplying. The surface is polished or matte, nickel or chrome plated. Non-standard models are made from metal, made in the color of gold, copper, silver or bronze.
• Plastic is a hygienic and lightweight material. Toilets weigh only 10 kg and last 10–15 years. Bacteria do not multiply on their surface, the structure is easy to clean, but it is advisable not to use too aggressive cleaning agents. Most often, plumbing fixtures are made from thermoplastic polymers, such as sanitary acrylic. Polyester resin and fiberglass give the structure additional strength. However, it is very fragile and cannot withstand high temperatures and melts easily.

• Stone is an extremely expensive material. Stone toilets are custom-made for very wealthy people. The types of stone used are onyx, granite, marble, travertine, polymer concrete, etc. The structure weighs 130–150 kg and can last indefinitely. A cheaper option is to use artificial stone. The most commonly used raw materials are acrylic resin and minerals. Stone surfaces are very porous. Bacteria and dirt collect in these pores, which is why an unpleasant odor begins to emanate from there. To prevent this from happening, the stone is covered with enamel, glaze or other durable coating.

Description of rimless products

Considering the appearance of both options, we can note the absence of any significant differences. A special feature is a slight design change that affects the flow of water when draining from the tank. Standard versions have a rim that helps distribute water throughout the entire interior of the toilet with complete washing of the surface. However, everyone understands perfectly well that it is under the rim that one can find the accumulation of dirt and the growth of bacteria, which negatively affects people’s health. To solve the problem, regular careful care is required, which takes time and effort.

In addition, there is another option - glazing the inner surface of the toilet. In this case, the problem area is covered with a special composition that prevents the accumulation of dirt and the growth of bacteria. However, this solution cannot be called durable, since regular cleaning of the toilet with cleaning agents and a brush will destroy the glazed surface. Consequently, after some time, sanitary equipment with a special coating again becomes a classic option, and the problem of contamination becomes relevant.

The structure of rimless toilets has been changed, which allows, to a certain extent, to solve the problem of dirt accumulation on the surface of the toilet. It is worth noting that such models do not have a standard correct shape; each manufacturer develops and improves it in its own way.

For example, in some models there is a small recess in the upper part of the toilet, while in others the toilet bowl is completely flat without any gutters. In both versions, the inner surface is washed by a powerful stream of water. This result is achieved thanks to the presence of special channels that divide the outgoing water into several streams flowing at a certain correct angle. It is worth noting that the design of the toilet does not allow water to spill beyond the bowl.

When deciding which toilets are better, rimless or rimless, you should take into account that various innovative technologies are used in the manufacture of rimless toilets, but this does not change the cost of the finished products. Toilets of this type are mounted on the wall using a profile, but this does not limit the degree of load on the product. Such equipment can easily withstand a weight of up to 500 kg. The seamless tank is also mounted into the wall, which eliminates the formation of leaks and minimizes the noise level from the operation of plumbing equipment.

Most manufacturers of rimless toilets provide a solid warranty on their products, so we can confidently say that the toilet will last a long time. As for replacing internal parts, the design provides for repair work without dismantling the equipment, using the technological channel of the water drain button.

How to mount

All unique models of rimless toilets are installed on standard water supply pipes and sewer pipes. Floor-standing and wall-mounted toilets are installed in exactly the same way as a regular standard device. There are many features of installation and installation of a wall-hung rimless toilet. The main feature is the fastening system.

How the installation process goes:

• Prepare a niche in the wall. The drain tank will be placed in this recess. First, the master makes a niche in the wall 60 cm wide and 100 cm high. Depending on the thickness of the flush cistern, the depth of the niche should be 15–20 cm. The drain must be brought to the same place where the toilet flush hole will be located. One more parameter must be taken into account: the sewerage system runs at a slope of 2 cm per 1 m of its length.
• Mount the frame and attach it to the wall and floor using dowels with a diameter of 1 cm. The fasteners that hold the structure will be attached to this frame. It is necessary that the parts are positioned strictly perpendicular to the wall. The wall-hung toilet must be fixed at a height of 40 cm above the floor.
• Supply water through a pipe made of polymer material, preferably polypropylene.
• Attach the bowl to the sewer drain using a short and strong corrugated pipe. The operation of the drain needs to be checked several times to make sure that there are no leaks. Then the cup will need to be removed.
• Cover the niche with waterproof material, such as plasterboard.
• You can decorate the sealed niche with ceramic tiles. This arrangement of materials looks very nice when the seams of the tiles coincide with the seams of the plasterboard sheet.
• At the very end of the work, the bowl is attached. It is held in place by special pins. It is necessary to check their strength and reliability.

In order for the structure to serve well for many years, you need to invite a specialist who can install the toilet correctly. Experienced craftsmen guarantee the quality of installation for the entire service life of the plumbing fixtures.

With microlift

A monoblock toilet equipped with a seat cover with a microlift is a very convenient plumbing fixture to use. The principle of operation of such a product is to automatically raise and lower the lid. This happens using the door method with finishing, only in this case the microlift system is more miniature. This purchase will be appreciated by both ladies and men.

The advantage of this innovation is that this particular device prevents a strong and sharp impact of the lid on the toilet rim. Thus, it protects the candy bar seat from mechanical damage and does not produce loud sounds when the lid is lowered.

Rimless toilet: cons

• Noise. A directional flush of sufficient power makes more noise than a circular flush.
• Poor quality flush in some models. This problem is most often encountered by owners of devices with an elongated bowl: the flow of water in it may be distributed unevenly. To avoid this problem, choose toilets with a funnel-shaped bowl.
• Splashes when flushing in some models. Formed when devices operate with an imbalanced hydraulic balance. Due to the absence of a rim, which is a natural obstacle, too strong or improperly cut flow causes splashes.

“Childhood diseases” of rimless toilets

Any technically original innovative invention is doomed to go through a period of so-called “childhood illnesses” - a period of identification in the process of mass exploitation of individual shortcomings that require comprehension and improvement. The rimless toilet, which has rapidly fascinated the world community, is no exception.

A number of models cause complaints from consumers due to the thin walls of the bowls, their small volume, partial splashing of water when flushing, and insufficient flushing power. Therefore, when choosing a specific model of such a “young” toilet, you should give preference to more experienced brands that have managed to cope with most of the design flaws of their creations.

So, which is better: a rimless or rimless toilet ? If you want to get rid of hard-to-reach places that complicate cleaning, the appearance of rusty streaks (when the water in the pipes is of very poor quality), and unpleasant odors, then feel free to give preference to rimless models!

How to prevent water splashing?

•If the drain flow seems too strong, O-rings may come in handy. Install them in the flush mechanism to limit the pressure of water entering the bowl.

•If the flow is not very strong, but splashes still appear, the problem probably lies in the divider. The part may be faulty or incorrectly installed. Check the position of the divider and replace the element if necessary.

•You can also purchase a tight lid and close the toilet every time you flush. Treat it with a disinfectant every time you wash your plumbing fixtures.
