Repair the toilet flush valve. The main components of the toilet bowl

Every home needs a toilet. It is exploited much more often than all the others plumbing fixtures so it breaks down the most. Its most vulnerable component is the tank. Due to mechanical damage to its internal components, the device becomes inoperable, and the owners will have to repair the old-style toilet cistern. Old-fashioned flush tanks have been out of production for a long time, but they can be found in apartments throughout the country, which confirms their reliable performance and durability.

Device

Do-it-yourself repair of an old-style toilet bowl with your own hands begins with a study of its structure and features. The main difference lies in the fittings, in which the water supply is lateral, and the design, in which the simplest physical laws are involved.

The main nodes are presented:

• A filling device, which includes a movable lever with a float and a valve to shut off the water;
• Drain mechanism.

In the design of the most “ancient” drain devices a cast-iron bell is included - a cork with a soft rubber gasket. After pressing the outer lever, the bell is raised, and the water moves down through the opened hole.

Important! This design is distinguished by great reliability, because the products serve for half a century, while repair work only periodic replacement of worn gaskets is required.

Later designs are equipped with a pear made of rubber or plastic instead of a bell. When the container is released, the float lowers, after which the valve opens, which starts the water.

Let's take a look at how they differ drain systems old pattern:

• Unattractive appearance. Previously, external attractiveness was not so important, more attention was paid to the reliability of the nodes and their performance. Therefore, the look of old products is not very aesthetic, with a primitive shape and a roughly processed surface.
• Tank location. Most often, the location of the tank is under the ceiling, and a pipe is intended for the passage of water - a riser. Due to this, a high speed develops in the water flow, which leads to a high-quality flush, but at the same time a lot of noise is heard.
• Design features of valves. Such products are distinguished by a very peculiar flushing system. It is based on the principle of a rocker, for work it is necessary to pull a rope or chain. The design is very simple, no instructions are required for assembly.
• Large water consumption. Such designs do not use economical drain modes, the water leaves in full.
• intake system. Water is supplied only from the side, which does not allow you to hide the hoses.

Important! In some cases, it is more advisable to replace the tank with a more modern product, for example, if the damage is too extensive.

Common breakdowns and repair options

Any, even the most primitive mechanism, can eventually break down. How to fix an old toilet cistern? Even a non-professional can deal with most breakdowns, there is nothing complicated about it.

Water flows continuously

In this case, we initially check if there is a leak in the filling valve. For this:

1. We remove the cover.
2. Raise the float lever.
3. If the flow of water continues, turn off the tap in front of the tank and drain the water.
4. Using a wrench, unscrew the part in which the valve and plumbing are connected.
5. We remove the float lever, fixing nuts, pull out the valve and replace it with a new one.

If water stops flowing after lifting the lever, the problem may be due to:

• Distortion of the float lever, as a result of which it clings to the sleeve. As a result, the float fails to fully rise and the valve closes. In this case, you need to pull out and straighten the rod.
• Float leaks. In this case, it remains partially or completely immersed in water, while the valve fails to close.
• The problem is solved by installing a new part. In case of absence required part heated plastic or sealant is used to repair the damage.

Water keeps flowing out

Toilet flush cisterns can be repaired even if the water drains completely. Such a sign indicates a violation of the tightness of the drain mechanism, in which water seeps between the bell and the body. This malfunction may be caused by:

• Corrosion or contamination of the seat surface. Due to deposits, the drain mechanism cannot close tightly. To fix the problem, clean the surface with sandpaper.
• The appearance of a gap between the seat and the body. For repair, tighten the fixing nuts with a socket wrench.
• Falling out of the guide sleeve from the saddle. Due to such a breakdown, the constipation is skewed when lowering. In this case, we insert the sleeve into the hole of the arc and wrap it with an elastic band.
• Incorrect position of the release lever. The pear does not completely cover the saddle and the water flows constantly. To get rid of the problem, we bend the lever and lower it below the inlet of the underwater pipe by 2.5 mm. In addition, be sure to check the fasteners that hold the rocker, tighten the loose screws.

Important! You will need a short tool to tighten the screws. During work, it is imperative to ensure that the vertical plate with four corners does not move out of the recess in the housing.

Supply hose problems

If the inlet hose or seals at the joint are damaged, drops will appear at the points where the hose connects to the housing. We carry out repairs in the following sequence:

1. Tighten the connecting nut.
2. We shut off the water.
3. Disconnect the hose.
4. We replace the gasket.
5. We put a winding on the thread.
6. Attach the hose to the tank.
7. We tighten the nut.

Loud noise

Even if the flush mechanism for the toilet has not broken, repairs are made. Even if the device seems to be working, but it makes a lot of noise.

To solve the problem, you can install a special stabilizing device instead of the part. If water enters the tank with a slight pressure, the problem is solved much easier. The filling valve mechanism includes a tube through which water descends. We vertically install a silencer on it, the lower end of which is lowered into the water at the bottom. For the manufacture of a silencer, we use a flexible hose made of rubber or plastic. After such an update, the noise from falling water and the sound of a galloping float will disappear.

Any toilet leak always causes a lot of problems. She begins to spoil the mood, annoying noise of continuously flowing water.

Large numbers appear on the water meter, you have to pay several times more for water. The surface of the toilet is starting to rust. Drops of condensate become noticeable on the pipes, which can cause corrosion and mold.

Tank leaks must be fixed immediately to avoid negative consequences.
Today, the resulting leak in the toilet bowl can be easily fixed without resorting to the services of specialists. But for this you need to understand the principle of operation of such a system and its components.

The tank can leak for various reasons. There is only one solution to fix it. Each tank design is different characteristic features. Therefore, the approach to solving such a problem will be individual. However, the most common is the "classic" design. Therefore, we will consider the problem of leakage, taking this design as the basis. We will give 7 solutions on how to fix a leak in the toilet and why the toilet can leak?

Reason 1: Overflow

Perhaps the most popular and obvious reason was the banal overflow of the tank. When the toilet cistern leaks water into the toilet. Excess water simply goes into the overflow hole. The main reasons for the appearance of such an overflow can be:

• The rubber seal has lost its elasticity. Long-term operation of the tank, led to a loose shutoff of the flow of water. The gasket began to deform and let fluid through;
• The gasket does not fit well and does not tightly close the outlet located near the drain valve, thereby creating a leak. Such a gasket has retained its elasticity, there are no signs of deformation. Water starts to flow due to its poor pressing against the wall of the toilet;
• It is possible that the valve pin that holds the float has frayed. This occurs during long-term operation and the appearance of corrosion on the body of the stud;
• There is a crack in the valve body itself. Water starts flowing through it.

Note! When a brass valve is installed in the tank, there simply cannot be any cracks. They only appear on plastic products. Brass parts are highly durable.

How to deal with such a leak

To quickly fix the problem when water leaks from the tank into the toilet, you need to find out true reason tank leaks. To do this, you need to do a little testing.

Remove toilet lid. Raise the float by hand. One centimeter is enough to stop the flow. Therefore, the float arm is not properly bent. It simply cannot shut off the water, it flows freely through the drain hole.

To correct and eliminate the leak, it is necessary to slightly bend the lever so that it begins to shut off the water as soon as it reaches a certain edge.

If after lifting the lever the flow does not stop, you need to carefully inspect the valve. The special fixing pin must be in place. It shouldn't have any damage. It should stop the float arm while inside the valve. In addition, you need to check the condition of the hole in which the pin is located. It may have been deformed.

Worn-out stud can be replaced copper wire, large section.

If the hole is deformed, a new valve must be installed.

It is possible that the leak appears due to the gasket. If, after pressing it against the valve, the water stops flowing out of the drain hole, you need to adjust its pressure. If it cannot be adjusted, a new gasket must be installed.

We examined the main causes and methods for solving the problem of tank leakage in the classical scheme. It has been used for over 40 years. However, every year there are new designs of tanks with a certain principle of operation. Try to further study their design.

Reason two: Bolts

Quite often, leaking water is associated with bolts that connect the cistern and toilet. Metal bolts become rusty over the years, plastic bolts simply burst, and the toilet bowl flows from this.

How to solve such a problem

First you need to carefully inspect all the fittings. You may only need to replace one bolt. However, in order not to additionally run to the store, it is better to immediately purchase a new set of spare parts for the toilet bowl.

To accurately determine the cause of the leak, you will have to disassemble the tank. Sometimes it is simply not visible which part is out of order, which requires immediate replacement.

How is the replacement

To fix a toilet cistern leak:

• Before starting disassembly, you need to turn off the water supply;
• Remove all water from the tank;
• unscrew flexible eyeliner through which water is supplied;
• Loosen all screws. If the body of the bolts is covered with a large layer of rust, they must be cut with a hacksaw. Buying new bolts is much cheaper than installing a new toilet. After all, the old one can be broken when unscrewing rusted bolts;
• The toilet bowl moves back;
• The shelf lying on the cuff is removed;
• The rest of the water is drained;
• All rust found is removed.

For assembly, all steps are performed in reverse order. New bolts are installed, rubber gaskets are changed.

When tightening the bolts, the slightest distortion is not allowed. Tightening should be done with little effort. If you start to press hard on the bolt, you can easily crush the faience.

Third reason: Pear

The rubber bulb failed and the toilet bowl constantly flows after flushing. With prolonged use, the rubber becomes inelastic. She becomes rough and cannot take the desired shape. As a result, water constantly flows in the toilet.

Solution

How to fix a leak in the toilet? Repairing a pear that has lost its shape is almost useless. You can spend a lot of time, and the result will be zero. It is much easier to buy a new pear in the store.

When buying, you need to choose the softest from several products. It can be used for a long period of time until it becomes rigid.

The fastening of the pear is made on the thread. To remove it, you need to turn the pear clockwise. For installation, the pear turns in the opposite direction. While there is no new pear, you can use the weight hanging on the rod. He will put pressure on the pear, and press it to the saddle. Any heavy nut can become such a load.

Fourth reason: Skew

A reservoir failure may be due to a skew or large displacement of the lever that holds the float. There are many reasons for the formation of distortion. For example, a hole through which water begins to enter the float. Perhaps the lever has moved a little to the side due to long-term operation.
Another reason when the toilet cistern is leaking can be poor-quality plumbing parts purchased at the store.

How to solve such a problem

If you purchased a bad float in a store, you need to change it to a more reliable and high-quality one. When a small hole is formed in the float, it is easy to close it with ordinary polyethylene. You can also heat a piece of plastic with a lighter and close the hole.

But such repairs are considered temporary, the float will still need to be replaced.

Fifth reason: depressurization

There was a leak between the toilet and the cistern. Such a leak in the area of ​​\u200b\u200bthe junction of the tank and the toilet itself appears if the joint has been depressurized. Usually the cause of this phenomenon is a large deformation of the rubber seal.

To eliminate the leak, a new gasket must be installed between the tank and the toilet.

This work is done in the following order:

• The water supply is turned off, for which the main water valve is closed;
• Remove all residual water from the barrel by collecting it with a soft kitchen sponge;
• Slightly unscrew the drain nut. It can be found right under the drain valve hatch;
• The screws that secure the tank to the toilet shelf are completely unscrewed. The tank is being dismantled;
• The lock nut is unscrewed, which holds the drain, after which it is removed from the tank;
• A new gasket is installed. Each gasket is made to a specific size and shape. Therefore, before buying a gasket, you must definitely choose the exact size.
• If the gasket is smaller or larger, the problem will remain unresolved;
• The drain assembly is fixed with locknuts;
• The tank is returned to the shelf and secured with bolts.

I must say that the leak between the toilet and the tank may be associated with other circumstances:

• The bolt holding the tank capacity on the bowl was heavily rusted;
• The insulation that seals the mounting hole for the bolt has become unusable.

Of course, you will have to install a new bolt and replace the seal. The work must be done in the following sequence:

1. The water supply is shut off;
2. Drained;
3. All bolts are unscrewed and removed from the mounting holes;
4. Sealing washers are put on the bolts;
5. The bolts are put in place and tightened with nuts.

Your cash costs will be:

• Gasket - 200 rubles;
• A set of bolts - 50-300 rubles;
• Master's services - 1200-1400 rubles.

Sometimes no replacement is necessary. Simply tighten loose bolts. To do this, hold the nut with a wrench, and tighten the fasteners with an ordinary screwdriver.

Care must be taken when doing this work. Ceramic products are not very durable. It is enough to tighten the bolt more strongly, and a crack may appear at the bottom of the barrel. To prevent this from happening, it will be much calmer to just put new gaskets.

Reason six: Shut-off valve

The check valve has failed. From this, water constantly flows from the tank into the toilet. You can of course try to disassemble the bleed valve. Adjust the pressure of the hatch on the drain pipe, slightly undermining its end. Such manipulations require a lot of labor, and the desired effect is not always achieved. This suggests a simple conclusion, you should not engage in repairs, it is better to completely replace the entire drain assembly, or the entire toilet flush tank.

To do this, you must perform the following steps:

• The toilet room needs to turn off the water supply. To do this, the central water supply valve is twisted.
• The remaining water is flushed down the toilet;
• Open the lid and remove any remaining water with a sponge;
• Remove fixing screws;
• The tank is removed from the shelf;
• The sealing gasket is removed;
• The lock nuts securing the drain assembly are unscrewed;
• The old mechanism is removed;
• A new system is being installed.

Before buying a drain unit, you need to try to purchase a similar model that used to be in the tank. In extreme cases, the same manufacturer. In other words, if the tank was manufactured by cersanit, then the drain unit must also be of the same brand.

The new assembly is secured with new locknuts, a new gasket is installed.

We return the tank to the shelf, new bolts are inserted into the holes. We fasten it to the toilet bowl.
It remains to connect the water and check the tightness of the new drain.

In principle, this work is not very difficult, it is enough to have a set of box wrenches and several adjustable ones.
Buying a new drain will cost 400-4000 rubles. It all depends on the type of mechanism. Elite systems are much more expensive.

If the work will be done professional master, you will have to pay 1600-1800 rubles.

Reason 7: Cracks

The toilet cistern is leaking due to a crack in the bottom or sides. With such a serious problem, you can cope without even changing the entire toilet.

What should be done

The tank is detached from the toilet and dried well. All cracks that appear must be covered with a high-quality sealant. I must say that this method gives the greatest effect. Of course, the sealant is not designed for long-term operation, you still have to buy a new tank and toilet.

If the toilet bowl with a button starts to leak

First of all, set the position of the switch. If the return spring is weakened, the button may simply remain in the shaft. As a result, the drain cover will always be in the "open" position.

To repair the toilet tank with a button, you must follow a certain sequence:

• The cover is being dismantled;
• The locking switch is removed;
• The spring is changing
• The seat is centered. It is located directly under the hole made in the lid.
• Perform reassembly.

Preventive work

If you do not want your toilet to break often, you must constantly perform certain preventive measures.

Once every six months, you need to clean the cistern and bowl of the toilet bowl.

Constantly monitor the condition of the fittings and related fittings.

Any toilet bowl does not "like" mechanical damage, it does not tolerate temperature fluctuations.

Timely preventive maintenance will extend the life of the entire system.

When a leak occurs, the simplest breakdowns are first corrected and only then they begin to solve more serious problems.

The leak of the drain tank can be eliminated with your own hands. The design of the tank is so simple that it does not require special tools. Having completed such repairs yourself, you will definitely get great pleasure.

Conclusion

We have given the 7 most common solutions to why water flows in the toilet. In 95% of cases, you have exactly the same problem. But if you've tried everything and nothing worked, then what to do if water is still flowing in the toilet bowl? Better call a plumber. He will fix the problem in less than an hour.

The drain mechanism for the toilet bowl from time to time malfunctions. There are two ways to solve the problem: call a plumber, waiting for a long and nervous time for his arrival, or fix the bathroom yourself. The second option is cheaper and faster, but for proper conduct works, you need to know a few nuances, including the device of the unit and the features of its operation.

general information

There are several designs of drain tanks on the market. Regardless of this, they are characterized by the presence of a pair required elements- floor or wall tank and top.

In the traditional installation scheme, the cistern and toilet are connected as one. The main advantage of the design is the combination of two elements without the need to install an additional exhaust pipe. Despite the effectiveness and practicality classical scheme, analogues of the built-in and hanging type. This allows you to completely hide the drain tank, and the system is started by activating the push-button controller located on the panel.

Types of flush mechanism for the toilet cistern

Most often, push-button or rod drain devices are used. The first option is relevant for containers closed type, the button is placed on the side or in the center of the tank. There is a variant of mounting the device with two buttons, one of which works in full mode, the second one drains half as much water. This allows you to save resources, if there is such a need.

Levers and chains are used in the system wall hung toilets. To operate the mechanism, it is enough to pull the lever connected to the chain. It is usually located on the side of the tank. Regardless of the type of installation, a distinction is made between mechanical and automatic flush. Repair of these two structures also has its own characteristics.

Water supply system

The device of the drain mechanism in the toilet cistern provides for two types of water supply, namely:

1. Side entry. It involves the placement of valves in the upper part. This design is preferred in domestic systems. Such a solution is characterized by low cost and ease of maintenance, however, it differs high level noise during water intake. In advanced modifications, a special tube is provided that contributes to the supply of water immediately to the lower part of the tank, which significantly reduces noise.
2. Submission of the lower type. This technology applied by various manufacturers, consists in the flow of liquid from the bottom of the tank. This design is quieter, more efficient, but also more expensive.

Toilet cistern mechanism

In order to correctly identify and troubleshoot, it is necessary to have a general idea of ​​​​the device of the mechanism in question. All modifications have a fairly similar design.

The inner part includes the following elements:

1. Shut-off and drain fittings that regulate the drain and prevent leakage excess fluid. When filling the tank, water helps to press the special valve more tightly against the drain hole. As a result, fluid leakage stops. If this functionality is not observed and the tank passes water, this indicates a malfunction or malfunction of the locking devices.
2. Filling type valve. It is combined with the water supply, focused on adjusting the water level in the drain tank. After reaching a certain level, the water supply stops. This principle of operation is typical for the device of the flush mechanism of the toilet bowl with a button. Modern models equipped with a filling valve in the lower bowl and a vertical placement of the float.

There is no water supply to the tank: what to do?

This malfunction is one of the most frequent in the system. The main reason is clogging of the narrow part of the valve element. You can fix the defect yourself without any problems: you need to release all the water from the tank, remove the valve along with the float and lever. Then, the opened hole must be cleaned with a needle or wire.

After that, the valve on the inlet pipe is unscrewed (for a couple of turns), the residual blockage is washed sewage. Next, you need to check for the free passage of fluid. If everything is in order, you can mount removed elements into place.

Water leakage into the room

If there is water in the room, the flush mechanism for the toilet cistern must be checked for tightness and integrity of the fasteners. At the same time, do not panic, blocking everything and everywhere, calling plumbers and ordering new toilet. Most often, you can solve the problem in the following ways:

1. Replace the sealing ring between the tank and the toilet bowl, after checking it for defects.
2. Carry out a similar operation with the gaskets of the fixing screws.

These malfunctions do not require careful diagnosis, they are detected by visual and tactile inspection. If these methods do not help, it is recommended to remove the tank and replace rubber compressor on the drain channel, as well as related elements on the fixing bolts.

Fixing a model with a button

Repair of the drain mechanism of the toilet bowl with a button is carried out in the following sequence:

• The retaining ring near the button is unscrewed. Do not apply extreme force, since the element is made mainly of plastic.
• Remove the cover and start repairing.
• If it turns out that the float is in the wrong position, correct it by first removing the cover.
• In case of deformation of the pear, it will need to be replaced. To remove it, fix the float in the upper position, unscrew the pipe and drain fastening nut, dismantle the entire part of the free mechanism.
• After removing the defective bulb, install the new model in the reverse order of removal.
• If the bolts for fixing the working elements are worn out, replace them.

Let's consider this process in more detail. It also consists of several stages, which include repairing the flush mechanism of the toilet bowl with a button:

1. Residual water is completely removed from the tank.
2. It is unscrewed which is located between the float valve and. At the same time, it is released by tilting the tank shelf.
3. The defective bolt and its paired counterpart are removed. This is important because new twin screws made of brass or stainless steel are selected next. Their size must be identical.
4. Dismantled faience under seat pears, thoroughly peeled. Similar manipulations are carried out with a shelf and a drain tank. The pear is lubricated with sealant, enhancing its tightness.

Assembly is in reverse order. To prevent deformation of fragile material, it is necessary to carefully tighten all fasteners with a small amount of force. After assembly, the assembly is checked by observing the presence or absence of leaks.

Malfunctions and repair of the trigger lever

Do not rush to learn how to remove the flush mechanism in the toilet bowl if there is no water drain when you press the button. In the future, this assembly will certainly need to be replaced, however, temporary repairs can be performed. Most likely, the cause of the problem is a violation of traction.

Temporary troubleshooting is carried out as follows:

• The rod is made of thick wire, twisted into several turns. It will serve as a replacement for the original element, however, its validity is very limited. Over time, the element will begin to bend and fail.
• Before starting repair work on the drain tank, loosen the lid locks. To do this, turn the decorative nut a couple of turns. This approach will allow access to the hosted node.

Replacing the drain tank

How to change the flush mechanism in the toilet bowl? To do this, open the lid. In its niche there are special drain holes with a diameter of 10-20 mm. They serve to supply water. One of these sockets is used to fix filling fittings equipped with a membrane-type valve.

Since the membrane is very sensitive to the quality of the liquid, its working life depends on the additional filter elements installed. In the case of a complete absence of filters, it is better to replace such a part with a lever rod counterpart.

The usual method of solving problems arising from malfunctions of the toilet cistern is to completely replace the parts. It will not take much time and will not require large financial investments. New fittings are bought for cheap modifications, taking into account the current dimensions of the connected pipes and threads.

Before installation, the joints are sealed, the reinforcement is tightened with a nut and bolt, and decorative plugs are inserted. Do not forget about seals and adjusting the tightening torque of fasteners, which should be in moderation. Otherwise, the ceramic and plastic parts, after which you have to start all over again.

Final stage

The bottom of the drain tank is equipped special hole for attaching to the toilet. It is made by means of metal or plastic screws with nuts. Each type of fastener has its own advantages and disadvantages: metal version more reliable and durable, but prone to corrosion. Plastic is not as durable, but is not afraid of moisture, although it requires the use of additional seals and gaskets. Main shut-off valves fastened in the center of the drain tank, fixed with a washer and a special gasket.

Well-established plumbing is the main condition for comfort modern man. But in the operation of the toilet cistern, a failure may occur, so you need to be able to quickly fix the breakdown yourself. This will save you time, money and nerves.

Construction device

The container for draining water into the toilet bowl has the form of a small tank that works on the principle of a water seal. Water is washed off in different ways: automatically when a button is pressed or by actuating a lever that opens a free passage for water.

The drain mechanism successfully performs its functions thanks to the important components of the valve:

• The sealing membrane of the siphon with a lid prevents water from flowing out.
• To enter water into the drain tank, there is a special lever connected to the water pipe.
• The filling volume of the tank is regulated by a float. It works in conjunction with a lever and a valve, connecting with them with a spoke.
• The overflow level tube is located to control the liquid level in the tank.

The old-style toilet bowl has features in the form of a vertical movement of the piston under the action of the flush lever. Shutting off the water supply from the side is due to the float reaching a predetermined level. Such models produce a set of water and drain with significant noise.

Modern designs have a different arrangement of reinforcement, it is closer to the bottom of the tank. The float rises along the vertical stem as the water fills up. With the help of the thrust acting on the membrane, the liquid level in the tank is limited. Thanks to the bottom water supply, rinsing and filling is carried out almost silently.

Characteristics of the main types of tank

In modern designs, the tank is most often attached to the toilet, connecting with it into a single whole. Separate location involves embedding the tank in the wall. There are also hanging options. Communication with the toilet occurs through a pipe. The advantage of such drain devices is the presence of a powerful pressure of the supplied water, increased several times.

There are also tanks with differences in triggers. Button models that operate in one mode (one button) or two (two buttons) have become widespread. The device is designed to save water. Under the action of one button, the tank is completely emptied, the second mode is for using half the tank. In one-button versions, you can adjust the incomplete flow of fluid.

AT hanging options flush tanks use levers or chains. Water is drained here mechanically when you press the lever, turn it or pull the chain.

According to the material of manufacture distinguish:

• cast iron;
• faience;
• plastic.

The strength of cast iron containers is confirmed by the time of their service, but at the same time they look old-fashioned. The configuration of faience structures is varied. They are one with the toilet. The plastic built-in tank usually has a flat shape.

Depending on the types of drain tanks, breakdowns also occur, and appropriate methods for their elimination are selected. Let's take a look at the most common problems below.

Water flows from the tank into the toilet

If the liquid from the container leaks onto the floor, then it is necessary to pay attention to the condition of the sealing ring that closes the connection between the bottom of the tank and the toilet shelf. In case of wear of the fittings, it is replaced with a new one. During the installation of the gasket, it is better to lubricate it with liquid silicone, which will improve the wear resistance of the part.

Leakage can also be caused by loose fixing bolts. Gently tightening or replacing them will stop the leak.

If water constantly flows into the toilet, first of all it is necessary to determine the cause of the breakdown:

• The skewed lever led to the lowering of the float to the bottom of the tank. You can eliminate the resulting skew manually by bringing the lever to its normal position.
• In case of damage, wear of the float, water enters the pear, preventing it from returning to its original position. Excess liquid has to be flushed down the toilet. You can replace the part of the drain mechanism yourself by blocking the water supply for a while. You can prevent the occurrence of a malfunction by paying attention to the material from which the float is made. Floats are resistant to damage, for the manufacture of which they used stainless steel or special plastic. For short-term sealing, the hole can be sealed by filling with heated plastic. It will help for a while and sealing the hole by wrapping the part with a plastic bag.
• Often the cause of leaks can be found in the wear of the seals, shut-off valve. Upon failure of these Supplies are replaced with new ones.

After the repair is completed, it is important to pay attention to the position of the lever and the float in relation to it. If the components of the mechanism are installed incorrectly, they are adjusted.

There is no water flow into the tank or it flows slowly

The ingress of dirt into the narrow part of the intake valve, its complete clogging - common cause such a malfunction. Before starting the repair, the tank is freed from water, then the damaged part of the drain mechanism is unscrewed along with the lever and float. Taking a long needle or a piece of thin wire, the passage is cleaned. The inlet pipe is also subjected to the procedure. To do this, first unscrew the valve. After checking the repair of the breakdown, tighten the valve and install the valve in place.

Slow filling of the tank is often due to the fact that the pressure in the water supply system is at a low level. Due to weak pressure water, it is difficult for a membrane-type valve to cope with its functions. With such malfunctions, it is better to go to replace the membrane with a rod.

Float repair and adjustment

The main elements of the drain mechanism include a float. It regulates the amount of water supplied to the tank, prevents it from overflowing. If earlier spherical structures often failed, then modern ones, similar in shape to a glass, suffer less from the effects of water.

The float is adjusted:

• by turning the lever, bringing to the selected level;
• movement along the axis with the help of a wheel.

If it is necessary to repair the float, it is easiest to replace it with a new one. In order not to make a mistake in the choice, disconnect the failed element. Purchased in a store of the same brand, suitable for a particular drain mechanism. Installing a new one is done as follows:

1. After closing the valve, empty the drain tank from water.
2. Using an adjustable wrench, remove the pipe through which the liquid is supplied.
3. Remove the old float and replace with a new one.
4. Adjust its position.
5. The water supply pipe is put in place.
6. By turning the valve, the tank can be filled.

You can return the float to working condition by first cleaning it of accumulated dirt.

Button repair

If the button malfunctions, it sinks, it is necessary to clean the element shaft from clogging. The malfunction of the button functions, when the water does not go away after pressing, is associated with a broken connection between it and the drain valve. You can restore the connection with a piece copper wire or purchasing and installing a new one.

Similarly, they cope with problems in the operation of a two-button design. The sinking can be corrected quickly: by unscrewing the retaining ring, raise the buttons to the appropriate level. Sometimes their position returns to normal after a few clicks.

Other possible malfunctions

There are other breakdowns in the operation of the drain mechanism:

• The reason for the failure of the lever is a violation of traction. Replacing an item with another involves buying a new one. For a while, the fittings can be replaced with thick wire, but it will not last long.
• In case of excessively noisy filling of the tank, open the lid and put the muffler tube on the fitting.
• If the fluid in the tank is constantly overflowing, you can avoid a malfunction by adjusting its filling level. The level of the edge of the overflow tube with lateral water supply must reach a mark ten millimeters below the hole. The tube is turned clockwise, set to the required height and blocked by turning it counterclockwise.

When installing sanitary ware in a new house or a recently purchased apartment, you need to worry about correct installation toilet bowl, strong connection of hoses and pipes, serviceability of gaskets and fasteners. Old plumbing also occasionally requires preventive examination. Because of Bad quality water fittings quickly wear out and fail, and then it is required urgent repair drain tank. The delay is worth the flooding of the home, including the neighbors below.

What is the sump made of

At first glance - the simplest device: a container equipped with a system for draining and supplying water. When the button is pressed, the mechanism drains the water, the supply valve opens, the empty container is refilled.

The main functional parts of the tank: 1(1) - inlet (filling) fittings; 1(2) - drain (drain) mechanism; 1(3) – water drain button. All details are connected

Do-it-yourself cistern repair

It turns out that even such an elementary device can break down. Let's consider in more detail how you can troubleshoot without resorting to the help of plumbers.

Troubleshooting the float mechanism

If water is constantly drawn into the tank and immediately flows into the toilet, look for a problem in the float mechanism. There can be several reasons for the breakdown:

• intake valve wear;
• skew of the lever ("rocker arm");
• buoy malfunction.

The float (buoy) from long-term operation gives cracks through which water enters it. It sinks and ceases to perform the main function - it just needs to be replaced.

If the lever is bent, it is necessary to return it to the correct one, horizontal position. The location of the lever is about 2 cm below the hole through which water enters.

Modern kits drain fittings have a different structure - they do not include a traditional float on the rocker, although the principle of operation of the mechanism has been preserved

The float mechanisms installed in the tanks of modern toilet bowls can be divided into piston and membrane. The former have the simplest design, in which the piston with the sealing cuff is pressed against the valve seat and thus shuts off the water supply. The latter are a relatively newer development - they can be found in the vast majority of modern cisterns. Instead of a piston with a gasket, they have a membrane made of wear-resistant silicone or latex, which makes it possible to significantly reduce the noise level during water collection.

The diaphragm valve of the drain tank, although it has more complex structure, however, gained wide popularity thanks to high reliability and quiet work

It is not difficult to guess that the failure of the locking mechanism is most often associated with the wear of the sealing gasket in the first case and the membrane in the second. In addition, malfunctions of float valves may be associated with malfunctions of other parts of the mechanism:

• axis of the control lever;
• saddles;
• hard cap.

Although the presence of inlet fittings of any size in the distribution network allows you to replace the entire assembly, you should not rush into this. A zealous owner will definitely disassemble the mechanism and, after identifying the cause of the leak, will eliminate the breakdown using improvised means. So, the sealing gasket can be cut from a piece genuine leather or dense rubber, replace the axle with a piece of thicker wire or a nail, and cut out the thrust cap from a suitable sealing material.

How to get rid of noise when filling the tank

The loud noise that accompanies the process of filling the tank with water creates discomfort for others. It is easy to get rid of it by adjusting the diameter of the inlet or adding small fittings plastic tube. Water will no longer flow freely, noisily into the tank, but will flow through the tube, respectively, the loud sound will disappear. To do this, we put a tube 30-35 cm long with one end on the hole, the other is placed below the water level with the tank drained. Even if the noise does not completely disappear, the plumbing will work quieter.

A plastic or rubber tube, worn over the inlet, muffles the noise of water entering the tank. This device relevant for tanks with top connection

Replacing bolts in case of leakage

Here, most likely, the steel bolts, which are the fastening of the tank to the toilet shelf, have rotted - they must be urgently replaced. Having bought a new set of bolts, we proceed to dismantle the tank:

• turn off the water by turning the valve perpendicularly;
• dry everything inside and remove the remnants of rusty fasteners;
• unscrew the nut and disconnect the intake valve;
• we unscrew the old bolts fixing the tank on the toilet shelf;
• remove the tank from the rubber tight cuff;
• take out the old bolts. It is necessary to remove both, even if only one of them is faulty;
• clean the junction of the bolts with the tank and the tank with the toilet;
• tighten new bolts;
• we install the tank on the shelf, having previously fixed the cuff;
• tighten the fasteners carefully so as not to damage the sanitary ware;
• let the water in and check if it is leaking at the bottom of the tank; a couple of times we lower the water and check again.

Sometimes a leak may appear a little later, so for two days it is worth occasionally carefully inspecting trouble spot. As you can see, it is not always necessary to carry out overhaul- sometimes it is enough to replace the fasteners.

To unscrew the bolts connecting the flush tank to the toilet shelf, a special tool is not needed: usually, “lugs” are provided for a comfortable grip

Toilet cistern fixtures are available at every plumbing store. The price of the cheapest is 40-50 rubles, the more expensive option will cost 250-300 rubles

Expert opinion

Viktor Kaploukhiy

If the toilet was used long time, then, most likely, the bolts connecting the tank and the toilet bowl are rusted so much that they cannot be unscrewed even with the use of universal penetrating lubricant WD-40. In this case, only a grinder will help, with which you need to carefully cut the bolts from the underside of the shelf. It is best if at the same time someone from the household will hold the tank - so it is guaranteed to remain intact. When looking for replacement fasteners, choose brass hardware. This alloy resists corrosion very well, so if you ever need to disassemble it, you can do it without difficulty.

What to do when water is constantly flowing

There can be no question of any water savings if it constantly flows in a thin stream into the toilet bowl, preventing the required volume from accumulating in the container.

Most likely, the matter is in the siphon membrane, which has worn out and lost the ability to hermetically close the hole. The problem is solved by simply replacing the membrane with a new one.

To do this, follow several steps:

• drain the water;
• remove the siphon
• remove the old membrane, install a new one;
• put the siphon in place, attach it to the lever, screw the fixing nut.

Sometimes it's not the membrane, but the breakdown of the thrust, which can also be easily replaced.

The siphon membrane is located at the bottom of the drain fitting. She represents rubber gasket, providing tight connection of parts

Viktor Kaploukhiy

Thanks to my varied hobbies, I write on different topics, but the most beloved are engineering, technology and construction.

The constant flow of water from the tank into the toilet is often not associated with any malfunction. This also happens when, for some reason, the overflow adjustment is disturbed. If the drain tube is set correctly, then the water level in the tank will be 20 mm below the plane of its cut. At the same time, the edge of the drain channel must be more than 10 mm from the inlet of the flexible pipe.

What to do if the drain tank does not fill

So, suddenly, the water completely stopped flowing into the tank. Will it be enough self repair Or do you have to call a plumber? Let's consider three ways to solve this problem.

First, let's check the serviceability of the supply hose. We turn off the water, disconnect the hose from the tank and place it over any container (you can also above the tank). We unscrew the valve a little, let the water run again. If everything is in order with the hose, water will flow freely into the container. Otherwise, you will have to replace it.

It is possible that the connection point of the supply hose is clogged, since after the repair of the pipeline, sand and other mechanical impurities that can clog small holes get into the water. You can try to clean it with a long, sharp object, such as a screwdriver.

Also, make sure the filter is clean. coarse cleaning if the tank is equipped with modern shut-off valves with diaphragm valve. To do this, disconnect the flexible hose and use pliers with thin jaws to remove the filter from the inlet pipe. To clean it of dirt, it is enough to place the part under a strong stream of water. If the filter is clogged with persistent deposits, then it should be placed for several hours in vinegar or a solution of citric acid, and then cleaned with a brush with hard bristles.

The cost of a new inlet hose is about 100 rubles. It is better to buy a product that has a shut-off valve - in case of leakage of the drain tank, it is much easier to shut off the water

If the failure of the float mechanism was due to wear on the intake valve, then it would be advisable to replace the assembly. The effort and time spent on repairs are not worth a couple of hundred rubles, which will have to be paid for new fittings. As practice shows, repair locking mechanism only a few succeed - most likely, you are not one of them.

Rebar replacement

If you don’t want to mess around with small parts of worn-out fittings, you can simply remove the old one and install a new mechanism purchased in the store in its place.

When removing old fittings, pay attention to malfunctions. Perhaps a complete replacement of the mechanism is not required, sometimes it is enough to change one small detail

Sets of fittings for drain tanks have design differences. For example, their structure is different depending on the type of eyeliner - side or bottom

To begin with, let's figure out how best to disassemble the structure using the example of reinforcement with a bottom connection:

• turn off the water;
• carefully unscrew the button;
• remove the cover;
• we disconnect the eyeliner;
• remove the drain column in parts: first dismantle upper part(rotated 90 degrees);
• unscrew the fasteners of the drain tank;
• put it in for further work on the toilet;
• we unscrew two nuts: fastening the valve and column, we take out the second part of the fittings;
• install a new mechanism and carry out reverse works for tank installation.

As you can see, changing the components of the tank is not difficult: the whole operation takes no more than 10-15 minutes. Another of the benefits independent work- no special tools are required, all actions are carried out with the help of hands, pliers and wrenches.
