How to fix a toilet bowl yourself

The principle of operation and components of the drain tank

Plumbing equipment quite often fails due to increased operational loads.

It is believed that the operation of the tank is arranged according to the principle of a water seal.

Repair drain tank toilet bowl - perhaps the most common type of activity, often carried out in emergency mode.

Repair of a drain tank is a general concept. Most often, the problem is solved by replacing the flap valve, lever, or even by simply tightening the nuts. The cause of the leak may be an ordinary rubber gasket, or rather, its wear.

Technically, a toilet tank is a water seal, the device of which is based on filling a certain amount of water for use when the shutter is opened.

The drain mechanism consists of the following fittings:

• levers representing the system;
• float;
• valve blocking the drain hole (seal);
• shut-off valve that prevents water from entering the tank.

Those who have already repaired the tank with their own hands can confirm that the drain mechanism is quite simple.

Elimination of disturbances in the operation of the toilet bowl when parts are shifted

Drain tank with a shelf, side start: 1 - tank cover, 2 - overflow, 3 - float. 4 - rod, 5 - lever, b - float valve, 7 - release lever, 8 - reservoir body, 9 - overflow nut, TO - shelf, 11 - stud, 12 - seat gasket, 13 - pear, 14 - nut, 15 - gasket, 16 - shaped gasket, 17 - saddle, 18 - arc, 19 - bushing.

There are often cases when repair of the toilet cistern is not needed - only adjustment of the fittings that provide drainage should be done. It is very easy to do it yourself.

First of all, turn off the water in the entire riser. After that, carefully remove the lid from the drain tank and study the device to determine the type of failure or breakdown.

Often the need for such actions is due to the fact that too little or, conversely, too much water enters the drain tank. Fixing the problem is very simple, you need to adjust the float lever with the wire holding the float. To do this, it is enough to slightly bend it, lowering or raising the float. Moreover, you can make a new lever using thick wire.

Another common problem is when water continuously flows into the cistern but does not fill it. The situation is caused by the position of the toilet float, which is most likely at the bottom or skewed. The repair consists in the fact that the float must be corrected by hand.

Troubleshooting simple toilet problems

Primary diagnostics of all fittings of the drain mechanism will help determine the possibility of do-it-yourself repair.

If the water flows continuously, you should try to push the drive rod down. The cessation of the leak indicates the looseness of the drain mechanism. To eliminate this malfunction, it is enough to carefully stretch all the connections.

A fairly common phenomenon - water flows from the junction of the tank with the toilet. In this case, it is necessary to replace the rubber gasket. The new gasket must be the same size as the old one. It is placed on top of the nut that secures the siphon.

It does not hurt to check the condition of the drain valve installed between the tank and the hose. To do this, disassemble the connecting mechanism, and then clean it with a special brush and assemble it.

How to get to the flush mechanism in the toilet bowl?

Scheme of the flush mechanism for the toilet bowl.

First of all, you need to establish from which place the toilet is leaking. Sometimes water flows through the cracks that have appeared in the toilet itself, but most often this is due to the operation of the cistern drain mechanism.

In this case, the repair will not do without pliers, new rubber gaskets and, if necessary, parts providing a drain mechanism. If you follow the instructions, it will not be difficult to repair the leak with your own hands.

Getting started, block the access of water to the tank. Then they examine a plumbing fixture - a toilet bowl with a flush tank.

In modern equipment, a drain mechanism of two types is used - push-button and lever.

In the first case, to drain, you need to press the button, in the second - pull the lever.

You should find the locking ring that holds the button and unscrew upper part buttons and ring.

With a lever drive, a handle is unscrewed at its end. This will allow the tank cap to be removed. This must be done very carefully, since the lids are sold only complete with toilet bowls.

Valve failure diagnosis and replacement

If you have to apply force when pressing the handle with a full tank of water to flush the water in the toilet, the flap valve, which is inside the siphon, has broken. Replacing a part is quite simple for those who know how to do something with their own hands.

Scheme of the construction of the drain tank.

The first thing to do is close the tap that supplies water. Then they perform the work in the following sequence:

1. Water is drained from the drain tank.
2. Disconnect the drain pipe.
3. Loosen the locknut.
4. Disconnect the pipes: overflow and supply.
5. Loosen the screws holding the cistern to the toilet.
6. Disconnect the hook from the top rod of the siphon.
7. Remove the siphon block.
8. The rod and the lifting plate are shifted along the guides.
9. A damaged gasket on the valve is replaced with a new one.

After that, the siphon is assembled and installed, while observing the reverse order. Do-it-yourself valve repair is completed.

If desired, you can upgrade the device of the drain mechanism. Instead of the old siphon block, it is recommended to install a new device, consisting of three parts. This will make it easier to replace the valve in the future without turning off the water or removing the tank. You only have to unscrew the connecting nuts to remove the siphon block. After that, on the bottom side of the block, the flap valve is replaced with a new one.

Today, there is a toilet in every apartment. Due to its purpose, it is operated much more often than other plumbing. Therefore, it breaks more often. And its most vulnerable component is the tank.

Tank device with bottom connection

The designs of all drain tanks have much in common. hallmark is only a technology for collecting and lowering water.

Today, tanks equipped with a button and a water supply from the bottom side have become very widespread. They are especially relevant when it is impossible to arrange a side connection due to insufficient space. The price of such products is somewhat higher than other models. But they work almost without noise and are suitable for repair.

Such a tank is endowed with one or two buttons - this is not particularly significant. Their number determines only the economy and water consumption.

These modifications have common feature – strictly vertical movement of the float. It is powerfully bonded with button and diaphragm valve. The button causes the water to drain. Under the influence of pressure in the pipeline, the inlet valve opens, and water enters. When the liquid level rises, the float rises at the same time, and with it the piston rod. It smoothly closes the intake valve. When the required water level is reached, the valve closes completely.

The diaphragm is responsible for regulating the water supply. Responsibility for changing its positions rests with ball valve. It can be controlled using a button located on the tank lid.

Drainage is carried out through a siphon, which is concentrated in the middle of the lower part of the body. It is attached to the outlet pipe with special gasket- saddles.

Adjusting the water level in such a system is much easier than in devices with side connection. There is a special limit here. Using it, you can control the level of the liquid. It fastens the float to the valve lever. The float is attached to it with a thread. To set the volume of water in the tank, you just need to change the height of the float using a plastic nut.

Possible breakdowns and methods for their elimination

If you suspect a breakdown, you must first block the water supply and remove the cover.

External leaks

You can't always see them right away. They become visible with the formation of red spots. Disassemble the tank, carry out diagnostics. If a hard filter is not installed, elements of dirt and rust can constantly accumulate in the tank. They can adversely affect the internal mechanisms of the system and cause it to break.

When the tank is working properly, it fills with water to the correct level. The pear is pressed against the drain hole and held in this position due to the action of water. When the trigger mechanism is activated, the drain hole opens. The pear must always be provided with air. A protective tube protects it from water ingress. If a pear or tube is damaged, the entire system breaks. Therefore, after removing the cover, first examine these items. If they are not elastic, cracks are present, then this is the cause of the leak. Repair in this case is not possible. Need complete replacement. If the pear is intact, look for dirt and rust under the rubber. They are removed with a sponge.

• The gasket between the toilet and the cistern may be loose. You need to remove the tank, examine it. If it is very hard and covered with cracks, there is only one way out - replacement. It might just be installed incorrectly. Then it is worth putting the gum more tightly. Although The best decision is also a replacement.
• Wear of the sealing elements under the connecting screws. Solution: the screws are unscrewed, the seals are changed. Tank removal is not required. It is better to put cone-shaped seals - they are more powerfully adjacent to the working surfaces. After replacing these elements, you need to tighten the screws so that there are no distortions. Their presence will lead to a new leak. The screws are tightened slowly and one by one.

Internal leaks

Their sign is the flow of water into the toilet. The reasons are usually:

• poorly adjusted overflow pipe;
• damaged valve;
• damaged float.

First, it is checked how the handset is configured. She rises slightly. You need to see if there is a transfusion of water into the tube under it. If so, the float valve needs to be repaired. If not, the lever is corrected.

The source of the problem can also be debris under the gum. If it is found to be worn out, it is best to replace it. If the valve or float breaks, they are also replaced.

Water does not enter the tank

The first thing to do here is to check the supply hose. It is detached from the tank, the end falls into any container. If there is no water, this hose will have to be replaced with a new one.

Another possible reason is the narrow component of the intake valve is cluttered. Repair procedure:

1. Draining the fluid from the tank, shutting off the water and unscrewing the assembly, which includes the valve, float and lever.
2. After these steps, a hole will open to fill the tank.
3. If there is a blockage, it must be eliminated. A regular needle or wire will help here. For total cleaning, the valve is removed from the inlet pipe, the remaining dirt is removed with water.

The appearance of noise in the tank during its filling

In fact, this is not a breakdown, but it causes a lot of discomfort. In most cases, noise is generated immediately after draining the water. Then they decrease.

Solution: pay attention to the locking mechanism, you need to put a piece of tube on its nozzle. It should be small. Material - rubber or plastic. The length of the tube must allow it to reach the bottom of the container. After this procedure, the noise will immediately decrease.

Noise can be eliminated in another way. It involves replacing the standard float valve with another option - a valve that has a special compartment and a stabilization function. After installing it, the noise in the tank will disappear forever.

Without many household items, including the toilet, it is sometimes impossible to do without. No wonder things like this often fail. The reason for this is frequent use. In this regard, the toilet breaks much faster than other plumbing items. The most vulnerable and fragile component in it is the tank, which consists of several internal elements. It is mechanical damage to internal parts that is the most common cause toilet breakage. Other reasons for which the device loses its performance include negligent handling and non-compliance with the rules for its operation. What to do and how to fix the toilet yourself, you will learn from this article.

Peculiarities

In order not to break the device and qualitatively repair problems, you need to know the device of the tank and its features. All toilet bowls have a design similar in structure. There are differences, but they are insignificant and consist in the mechanism for starting water.

There are several types of drain tanks: with one or more flush buttons, as well as with a lever. Regardless of which drain system is used - lever or push-button, this does not fundamentally affect the mechanism of operation. However, an important advantage of a push-button device is its affordable price and quality, which is confirmed by years of operation.

There are also devices that have an installation. They are separate structures between the drain tank of the appliance and the bowl itself. This is one of the most advanced modifications of the bathroom, the height of the tank of which may vary depending on the model of the toilet. The location height determines the level of remoteness of the drain tank from the bowl and is often about a meter. The elements in this design are interconnected hidden pipe. This version of the bathroom has become very popular not only because it is high-tech, but also because, thanks to its excellent design, it will fit well into any interior - from classic to high-tech.

Technical capabilities Such models guarantee fast flushing and good water pressure. Often in models of a separate design, the drain tank is hidden in attic or in hinged structures- for example, a false ceiling.

There are also variations when the drain tank is at a low level.- it is mounted in the wall not far from the toilet bowl itself. These elements are connected by a short pipe, and the drain mechanism is located directly at the end of the tank, but this affects the speed and pressure of the water.

There is also a classification of devices according to the type of installation.

• There are hanging tanks that are attached to the toilet bowl at a short distance and are connected by a special pipe.
• Drain compact device. Tanks of this type are mounted directly on the so-called toilet shelf without the use of additional devices, such as connecting tubes.
• most complex structure is a built-in cistern that is used in hanging devices known as installation toilets. The drain tank in this design is installed inside the wall.

Despite the fact that there are several types of drain tank designs, they have the same structure and can be represented as several elements that are in constant interaction with each other.

The main one is the inlet valve, which is designed to maintain the water level in the tank at a certain level. This allows the float, which is fixed to the filling valve and controls its action. It is he who opens and closes the channel through which water enters the drain tank. It works due to the fact that when the tank is filled, it rises and opens access to supply water to the device.

The overflow valve or the so-called "drain" valve operates depending on the type of toilet bowl and its parameters. To date, most toilet tanks have a special button that triggers the action of the drain valve. In other variations of this type of plumbing, there is a manual control, presented in the form of a lever or chain. If you pull on them, the water supply to the toilet will begin.

Another element, without which the design of the drain tank is impossible, is the overflow, designed to set the water level limit for each specific device. If this mark is exceeded, water, due to the action of the overflow, will not pour out through the walls of the tank, but will flow into the sewer through a special overflow pipe.

As noted above, there are several varieties of systems for running water into the toilet. The design of tanks with automatic descent of water (water is supplied after a short press of the button) works quite simply: the float is at the bottom, in the lowered position, which starts the action of the filling valve. Thanks to this simple manipulation, the water supply through the inlet valve opens. Once she reaches required level, the float rises, thereby blocking the flow. The flushing system in a similar design is controlled by pressing a button, which is located on the upper end of the drain tank: the overflow valve opens and passes water directly into the toilet itself.

Often, manufacturers install several drain buttons, which greatly complicates the structure of the drain tank and its operation. Despite this, devices of this type are designed for reasonable and economical water consumption, since when one of the buttons is pressed, only a partial discharge of water into the toilet occurs. To completely drain, you need to hold down the second button. Thus, a person can regulate the necessary water consumption himself, which will positively affect his budget.

Manufacturers create many variants of devices that are designed for toilet rooms different sizes. For small toilets, it is customary to use new models of toilet bowls, in which drain tanks are equipped with a lower water connection. Main Feature such a device is the presence of a valve from a special membrane. It opens under the influence of water pressure and, opening slightly, supplies water to the device. In case the water reaches a certain level, this membrane valve closes and stops the water flow. This is due to the pressure that the float exerts on the piston rod - due to this, the diaphragm valve overlaps.

After familiarizing yourself with the device of the drain tank, the master will be able to assess the problem and repair typical faults that do not require the call of specialists.

Required Tools

Toilet repair is not the most difficult procedure, which requires only care, some skill, time and the availability of the most simple tools. Among them are pliers, a set of keys, a universal screwdriver, side cutters - these conventional tools found in every home and will be indispensable assistants during plumbing work.

Let us consider in more detail some atypical devices that may be required when repairing plumbing. Among them is a pipe deburring tool that allows you to clean pipes - for example, to remove metal residues left after cutting a pipe. This tool can be replaced with a countersink. Sozh-sprays and special lubricating oils are also needed.

If the above tools are not available, then you can contact the store building materials and purchase a ready-made plumbing kit that will provide the home master with all the necessary appliances. Lack of tools can negatively affect quality repair work.

How to repair with your own hands?

Despite the fact that the device of this plumbing fixture is quite simple design, it may be subject to mechanical failure. If the toilet is broken and does not work, it is not necessary to call a team of specialists, since you can fix it yourself.

Before repair, it is necessary to make a correct diagnosis of problems. This stage of work is the most important, since it involves assessing the state of the device, and making a mistake at this stage means doing the job poorly.

Nevertheless, self-repairing plumbing is not a difficult task, but it requires a lot of time resources and efforts, which significantly overlap the finances spent on calling the masters.

It must be understood that there are several varieties of plumbing systems used in the drain tank device. The most modern of them is the lower water supply to the device. In this type of toilet bowl, the inlet mechanism, that is, the valve, is located in a special tube located inside the tank. The mechanism of operation of this device is practically the same as the old type models: if the valve is open, then water enters the tank. When it fills up, a float rises, acting on a valve that closes the water. Otherwise, the system for draining and overflowing water remains unchanged and differs little from the classic models: the same valve and tube are used, the latter is brought into the drain and equipped with an adjusting screw.

Based on this, you need to choose those techniques and tools that will have to be guided in the subsequent repair. The most common problems are discussed in detail below, but it is worth noting right away that most problems with plumbing fixture can be resolved by adjusting the tank fittings or completely replacing the fittings.

Fixing a plumbing problem

There are many types of breakdowns. They can be more or less serious, but they all lead to the fact that the toilet comes into a damaged position and ceases to perform its functions. This is often accompanied by increased water consumption, for example when the device is leaking. Of course, this affects family budget which few people like. In order to avoid such unpleasant consequences, it is necessary to pay attention to the problem in time and carry out quality repair, which can be carried out independently, without calling a team of specialists.

Leakage of water on the floor is one of the most common problems faced by consumers. The problem occurs in older models, and in the most modern devices with bottom water supply. The leak is connected to the o-ring through which the water flows. This element is located between the so-called toilet shelf and the bottom of the cistern. It often happens that the ring is out of order - cracked or changed shape. Other possible option a cracked gasket may protrude on the mounting bolts - they attach the tank to a special shelf or so-called bowl. To solve the problems of a leaking toilet bowl, it is necessary to replace the mechanisms.

When installing new fittings, professionals advise lubricating it with liquid silicone in order to extend its service life.

It happens that the water does not stop in the device, the toilet flushes it itself, even if the flush button is not pressed. This failure is associated with overcrowding of the drain tank. In this case, the liquid flows through the overflow pipe. This often happens due to a shift in the height of the overflow or a malfunction of the float. It may lose its tightness and, therefore, it does not fall tightly on the filling valve. Another reason may be the wear of valves. To solve this problem, you need to change the float. In the event of a defective shut-off valve, the drain must be replaced.

If the flush button sinks, you can try without removing the tank cover, press it again several times - often it is on its own due to mechanical impact falls into place. If this did not happen and the button is still stuck, you need to remove the top cover, remove the retaining ring from the flush button and subsequently install a new button. Also, this problem can occur when the button shaft is clogged, which needs to be cleaned and installed back. For a toilet with an installation, the masters advise you to disassemble it yourself button mechanism and evaluate it for damage.

If the system uses a push-button flush mechanism, then often the problem lies in the malfunction of the built-in lever that connects the drain, where water should flow, and the buttons. In this case, it is necessary to repair the fittings in the drain tank and the lever mechanism itself. This problem is typical not only for automatic flush systems, but also for unisex with a flush chain or handle.

In case of noisy filling of the device, it is necessary to remove the upper end from the drain tank and examine the condition of the mechanisms inside the tank. If the toilet "beeps" and makes other unpleasant sounds, then this may be due to the disconnection of a special tube that supplies water to the tank. This problem is most common in toilets with side water supply, where due to the disconnection of the tube, a noisy flow of water into the device occurs. To get rid of this problem, you need to drain tank connect this tube to the fitting.

If the toilet does not flush, then this is due to the obstruction of water into the device. You can repair plumbing - you need to check the inlet and clean it with a thin tool - for example, steel wiring. After that, it is washed with water and the valve removed from the tank is installed.

There may be a small amount of water in the drain tank, which will not be enough to flush. This happens because some system elements are in the wrong position: for example, the float does not rise. You need to study its position and adjust it.

Redecorating

During the operation of the device, both plumbing and aesthetic problems may occur - for example, cracks and other cosmetic problems may appear. In order to solve them, it is not at all necessary to call a plumber or buy a new tank: anyone can fix the breakdowns and return it to its original appearance. House master with your own hands.

In order to seal the crack, it is necessary to use a specially designed for ceramic surfaces glue. It helps to repair chips or cracks, but does not give any guarantees of a complete disposal of the problem.

A crack is often formed due to the fact that a temperature difference occurs, which leads to uneven and uneven distribution of the material. This, in turn, creates a large internal stress, due to which a chip or gap is created on the material. If the toilet is cracked, then mechanical damage becomes another cause of destruction. Often some objects fall on it, because in modern apartment buildings rather small rooms are allocated for toilets, in which residents want to accommodate not only the bathroom itself, but also various shelves. They have household chemicals, which falls and creates a crack.

The bursting section of the material on the toilet can be glued together if you use sealants made of sanitary silicone, which prevents the formation of mold and fungus. Moreover, this material is characterized by high resistance to chemical and hydro influences. Therefore, it is advisable to use this particular type of sealant for any part of the toilet bowl and even the sewer pipe. The entire area of ​​damage must be covered. In order to close the hole, it is necessary to leave a small margin and take into account total area future seam.

Without such plumbing device, like a toilet, it is already difficult to imagine normal living in an apartment. Only, like any plumbing, it can also fail, and more often this happens very unexpectedly for residents. But you can fix a lot in it with your own hands without calling the master to the house. Adjusting, for example, the button to if it sinks or does not work at all, or completely replacing it with a new one is quite realistic and independently without the involvement of specialists, even for a person who does not have much experience in such work.

The device and principle of operation of push-button tanks

All drain tanks are structurally very similar, the difference is only in the mechanism for starting water. They are a container for storing water needed to drain after using the toilet. Equipped for work with fittings. Consist of:

• filling valve;
• float;
• drain mechanism;
• overflow protection.

The principle of operation of the drain tank is quite simple. When the float is lowered down, water enters through the filling valve, which is responsible for maintaining the liquid level in the tank at a certain level.

Drain tank with button

The float itself is attached to the filling mechanism and directs its work, rising when the tank is filled, and falling when it is empty.

Attention! In addition to the already familiar cisterns in which water is connected from the side, other types of devices are increasingly common today. In them, water is supplied to the tank below. They differ from devices with side connection in the presence of a membrane valve that regulates the water supply.

The drain mechanism is controlled manually using a button on the tank. It is equipped with overflow protection - a mandatory element of the tank, which is adjustable in height when a limit is set in the liquid level. When it is exceeded, it goes immediately to sewer pipe without spilling out of the container.

Types of push-button flush mechanisms

The drain valve is connected to the button on the tank. When you press it, the water drains into the toilet. Drain mechanisms come with:

• one button;
• two buttons.

In the first option, when you press the button, the entire volume of liquid in the tank is drained into the toilet. The button in the second version is divided into two parts. When the small button is pressed, the water is not completely drained. And if you press the big one, it will pour out of the tank into the toilet bowl into in full. This separation allows you to save water in the apartment and not overpay for its excessive consumption when draining.

Toilet button malfunctions

Any item is designed for a certain period of use. So the service life of the button in the toilet also has its limits. But it can fail even earlier if the mechanism was originally made with inadequate quality. And if the button began to function poorly as a result of mechanical damage, it may be necessary to completely replace it with a new one.

Toilet cistern button mechanism

As a result of one or another malfunction of the drain mechanism, the button, when pressed, can:

• sticky - you have to press the button more than once to drain the water;
• fall through - the button drops when draining, as if falling inward.

Elimination of breakdowns and malfunctions

When the button sticks, and it takes repeated pressing to drain the water, then the problem is most likely in the stem that connects drain valve with descender. To fix this you need:

• block the access of water to the drain tank and drain the one that is in it;
• open the tank by removing the lid, then unscrew the retaining ring from the part of the button that is inside and remove it. After that, remove the button;
• repair the stem or replace it with a new part;
• after the repair or partial replacement of parts, assemble everything back.

Advice. If the stem needs to be replaced, but it is not possible to immediately supply a new part, you can temporarily replace it with a homemade element made from a piece of thick wire.

In the case when the button fails when pressed, one of the reasons for this may be a broken spring, which returns the mechanism to its original state. This will require replacement of the broken part. Another possible cause If the button fails, it may turn out to be an incorrect choice of the height of its location when adjusting the drain mechanism. To eliminate this, you need to turn off the water supply, drain the one that remains, remove the lid from the tank. Then remove the drain valve. After loosening the latches, adjust the height of the glass, then assemble everything back and check if the system is working normally now.

Replacing the button with a new one

Sometimes it happens that it is not possible to repair a damaged part, or it is no longer repairable. Then you may need to completely replace this button with another one. The new part must fully match the one that broke. If desired option could not be found on sale, then the drain mechanism itself will have to be changed. To carry out work on replacing the button, you need to remove it with disconnection from the exhaust valve and install a new device. All work is best done with sufficient care so as not to accidentally break other fittings in the tank.

A flush button that sinks, fails, or doesn't work at all usually causes enough inconvenience when using the toilet. Therefore, do not delay the decision important issue for a long time, especially since you can try to adjust the system, repair or replace the part yourself. If you can’t cope on your own, it is better to call a specialist to fix the problem.

Dismantling the toilet cistern lid: video

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 in order to carry out the work correctly, 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 of mandatory elements - a floor or wall tank and an upper one.

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 hide the drain tank completely, 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 use push-button or rod drain devices. 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 facilitates the supply of water immediately to the lower part of the tank, which significantly reduces noise.
2. Submission of the lower type. This technology used 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

To correctly identify and troubleshoot problems, you must have general idea about the structure of the considered mechanism. All modifications have a fairly similar design.

The inner part includes the following elements:

1. Shut-off and drain valve, which regulates the drain and prevents the leakage of 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 the removed elements in their places.

Water leakage into the room

If water appears in the room, the flush mechanism for the toilet bowl 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 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, and related elements on mounting 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.

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. The faience under the seat of the pear is dismantled, thoroughly cleaned. 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

The usual method of solving problems arising from malfunctions of the toilet cistern is to completely replace the parts. It won't take long and won't require a big investment. financial resources. 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.
