Water is running in the toilet. The toilet tank is leaking: causes of leaks and ways to eliminate them

There are several reasons for malfunctions of the toilet flush system, let's look at the main ones:

1. Water flows through the overflow

The tank overflows with water and it simply comes out through the overflow. Why does the tank overflow with water: the gasket in the valve is deformed:

installation of a toilet flush fitting of a new design:

• the weak point of this design is the membrane gasket that blocks the water; a small piece of rust can cause a leak through the overflow;
• over time, the rubber part lost its elasticity and stopped tightly covering the water;
• The gasket is not pressed firmly enough:
• the element itself is not broken, it is simply weakly pressed against the hole of the drain valve;
• the pin that holds the float lever located in the valve body is rusted or lost;
• the float lever has moved;
• the valve could simply crack if it is plastic (If the device is made of brass, a similar reason is impossible);

First of all, disassemble the upper part of the shut-off column in which there is a gasket-membrane and remove debris, in 80% of cases the cause is garbage. Wipe the membrane and valve surface with a clean cloth and remove any foreign debris.

If the water supply system does not have a coarse filter (mesh), be sure to install it, this will help avoid recurrence of the problem.

The most common problem is a misaligned lever. To correct this situation, it is enough to return the lever to its place: it should lie horizontally, lower than the pipe inlet. To eliminate a continuous leak from the overflow: Remove the top cap of the overflow tank. Raise the float one centimeter: if the leak has stopped and you didn’t need much effort to do it, your search is over. Turn the float lever a little so that it closes the water earlier. If water continues to flow when you raise the float, you most likely need to pay attention to the valve. The design of the valve itself has a pin that secures the lever; make sure that it is intact and intact. A damaged pin can be replaced with a piece of copper wire. Also, there should be no holes in the place where the stud is attached. If it does exist, you will have to buy a new valve.

Be sure to take the faulty part of the mechanism with you or take a photo of the faulty part.

If water constantly flows despite the gasket being tightly pressed to the valve hole, the problem can only be solved by purchasing a new drain mechanism. We looked at an example of a classic (Soviet) toilet, but if you have a modern device, look for the origins of the problems and their solutions by studying your toilet model individually.

• If the plumbing is new, leaks may be caused by improper installation.

The water begins to flow before it reaches the overflow. Water constantly flows, regardless of whether the overflow level has been reached or not. Why is water flowing: the bolt that holds the toilet and shelf together is rusted (if it is steel) or cracked (if it is plastic). Remedy: Make sure water flows only to the overflow level. Turn off the water and flush the tank. Dismantle the flexible line coming from the tank. Remove the bolts that secure the shelf to the toilet. Inspect the fittings: if they are in good working order, it is enough to replace just a couple of bolts, or buy a new set of fittings. Rusty bolts need to be cut off with a hacksaw. Remove the shelf from the cuff, drain the remaining water and place the mechanism on a flat surface. Reassemble the tank with new bolts, preferably brass. Repeat all steps in reverse order. Experts recommend replacing the rubber gaskets in any case. If necessary, tighten the cuff with an aluminum tie or copper wire.

• Water leaks between the toilet bowl and the cistern

1) the problem can be solved easily: just tighten or simply correct the part. Causes of the problem: a faulty cuff is most often the cause of water leakage. Regardless of what material the cuff is made of, there are clamps for both plastic and metal. Tighten the cuff with clamps carefully, not too tight, but not too loose. If the cuff device is corrugated, then it can simply move. In this case, simply return the part to its place and secure it.

2) Replacement of rubber gaskets, tightening of bolts and nuts. Causes of the problem: too weak fixation of the shelf to the tank. Just tighten the fastenings. Metal bolts rust and become deformed over time, but this does not happen to brass bolts. If tightening the bolts and nuts does not help, check the rubber gaskets. They need to either be completely replaced or repaired (dry, apply sealant, dry and reinstall with bolts).

3) Replacing the drain tank. Cause of the problem: Water leaking between the tank and the shelf may be a sign that the shelf is completely broken. This kind of problem is very serious. It is better for you to consult a specialist, because a breakdown often requires a complete replacement of the toilet bowl or even the flush tank. Plumbing products should be regularly inspected for cracks, including the cuff and pipes. toilet design Toilet design for a better understanding of the problem Water flows simultaneously with the flush The essence of the problem: every time you press the flush, water begins to leak from under the tank.

4) Check the serviceability of the drain mechanism inside the tank. Take the valve with your hand and press it lightly. If the leak stops, it means that the reason was hidden in the loose fit of the valve in the center of the tank. In this case, you just need to replace the gasket in the valve. But this reason is far from the only one.

5) The next reason for the tank leaking may be a displaced drain button. If the height adjuster has moved and the valve is higher than the drain hole, then a gap will form between the drain and the shut-off valve. You just need to return the water height regulator to its original position. The breakdown is quite simple and not at all costly.

6) A loose nut on the outside may cause water to leak out. You need to carefully and carefully tighten the nut and also check all the fasteners that secure the flush cistern to the toilet. Minor damage can be repaired and eliminated. The cost of replacing a toilet in Chelyabinsk, in particular here, is not high -

5 rules before going to the store

There are several rules that I try to adhere to before going to the store for tools or spare parts:

• 1) — Make a shopping list so that you don’t forget anything and don’t buy too much.
• 2) — Take a photo of the unit being repaired or the assembled spare part, a nameplate with markings if there is one. This makes it easier to explain to the seller, show the photo and he will immediately understand you.
• 3) - Take exact measurements, do not trust “measurements by eye”.
• 4) - Do not buy “for future use”; such purchases usually gather dust in the pantry or garage, and if they break down again, they cannot be found and you have to buy them again.
• 5) - Do not buy used tools or spare parts, no one knows how long they will last and who knows, perhaps the “unheard of cheap” electric drill was stolen. As you know, free is only in a mousetrap.

You hardly pay attention to the plumbing if it works smoothly. But you become wary if the toilet starts to leak or make unusual sounds. And there is every reason for this, because a leaking toilet is a serious thing, it can cause a lot of trouble not only for you, but also for the neighbors below. To avoid having to explain yourself about flooding, you need to regularly check the performance of your plumbing. And if a leak does occur, then you need to act immediately before it leads to serious consequences.

Condensation can form because the water and air in the room have different temperatures or because the drain tank has failed.

Sometimes condensation appears immediately after installing the toilet and this is eloquent evidence of the low quality of the product. So let's look at a few examples that can help you understand the cause of the problem.

1. It happens that the water does not drain from the tank for two to three hours, which is why it heats up to the air temperature. In this case, the condensation disappears, but provided that the tank is working normally.
2. Sometimes the hood is to blame, but then there must be condensation on the pipeline. Examine it.

The condensation problem can be solved in one of the following ways:

• reduce the frequency of draining the tank;
• reduce humidity in the house;
• raise the temperature of the water entering the cistern.
• change the tank itself, but only if you are firmly convinced that it is faulty.

Video - What to do if the drain tank is leaking?

As you can see, the reasons for a toilet leak can be very diverse, so each individual case requires an individual approach. If you encounter something new, then do not be afraid. It often only takes a few minutes to detect the problem. As a last resort, you can always contact a specialist - a plumber. And the last thing: regularly check that the drainage and water supply are working properly– timely detection of malfunctions will save you from many problems related not only to money.

"Tool" for universal repair

Do-it-yourself toilet repair is a procedure that many people have to deal with from time to time. You can replace various failed parts yourself, but sometimes the breakdown is so complex that it is not possible to carry out the repair yourself. A leak in the toilet cistern belongs to the category of serious toilet breakdowns.

Having discovered that the toilet tank with the button is leaking, the owner immediately thinks about what to do if water is flowing in the toilet. Our article will tell you why water leaks in the toilet, what types of breakdowns of such structures occur, and how to eliminate a leak in the toilet tank.

Toilet device

To understand the specifics of repairing a toilet bowl yourself, you must first of all know how this very toilet works. It consists, in fact, of the toilet itself, and the flush cistern, which is a very important element of the entire flush mechanism. Up-to-date information on what to do if the toilet tank is leaking will also be covered in this article. Photo No. 1 will show readers what elements a toilet flush device consists of.

So, the toilet cistern functions on the same principle as the water seal. It is based on a whole complex of levers, a float and a seal. Modern toilets and their cisterns come with a flush button. When pressed, water is supplied to the bowl, and it is with the flow of this water that all waste moves into the sewer.

Next, the drain tank is filled with water through a special hose until the bowl becomes full again. When the water in the drain tank reaches the required limits, a special shutter valve blocks its further flow into the tank reservoir, and nothing can be washed off with water. It must be said that in older models of toilets, the cistern lid is simply and easily removed.

But in the best models of modern toilets, such an element comes complete with a flush button located on the top cover. In the second option, before you start repairing the toilet with your own hands, you must first remove the flush button from the flush cistern by removing the fixing ring.

For this purpose, the ring is scrolled counterclockwise, or pryed with a sharp object (for example, a nail file). After such manipulations, the drain tank lid is usually easily removed from the main tank. If it is fixed on the tank with fasteners, then unscrew them before removing this element. In photo No. 2 you can see how the flush toilet cistern is designed.

We would like to draw the attention of readers to the fact that the cistern lid is not sold separately, but is sold together with the toilet. That is why you should remove it from the toilet cistern tank very carefully. If this element cracks or breaks into pieces, it will not be possible to replace the toilet tank alone, since it is not sold separately. In such a deplorable case, even repairing the toilet will not help; you will have to completely replace it.

It must be said that in some models of modern toilets, flush cisterns are supplied not with a single button, but with two button elements. The best way to remove the lid from the tank is to initially press both buttons in turn (as shown in photo No. 3), and then unscrew them counterclockwise until completely dismantled.

Many manufacturers strive to make the mechanism of action of a toilet with a button on the tank better, and therefore the designs of different toilet models differ slightly from each other. The cistern lid must be removed before repairing the toilet with your own hands.

This will allow the technician to carefully and carefully examine the structure of the toilet cistern, determine the cause of the breakdown of the flush cistern, and replace damaged parts if necessary. The following video will tell you in detail about the structure of the toilet cistern:

Types of faults

As a rule, home owners begin to think about repairing a toilet with their own hands at the very last moment, when a leak has already appeared. The fact that malfunctions and breakdowns occur in the operation of the toilet cistern seems insignificant to them and does not require attention. Usually, neglect of the fact that the toilet is leaking after flushing continues exactly until the receipt of utility bills for water is received.

Looking at the water meter, the inhabitants of the house understand that this same water flows away in exorbitant quantities. And at this moment they suddenly remember that water had already started flowing from the toilet tank a long time ago. And besides, the neighbors below began to complain a few weeks ago that water was flowing from your apartment onto their ceiling, causing the formation of unsightly stains on it. The reason that the water from your toilet is flooding your neighbors is most likely a leaking coupling that requires repair, which connects the flush cistern to the toilet.

But, regardless of the reasons why the toilet tank is leaking, the current situation, without a doubt, leads to a lot of problems for the owners of the house. And therefore, you should start repairing the toilet yourself as quickly as possible, or use the support of qualified specialists. The video will tell you in detail how to properly repair a tank when leaks are detected.

Among the known breakdowns of the toilet cistern are the following:

• The toilet cistern has a leak through the overflow.
• Water flows between the cistern and the toilet.
• The toilet leaks after flushing by pressing the flush button.

Many apartment owners often have to deal with the problem of a leak in the toilet cistern. You can determine why the toilet cistern is leaking and repair the toilet yourself, or by inviting a professional to your home who can approach the repair with full responsibility. Photo No. 4 shows an example of disassembling the flush mechanism of a modern toilet.

At the same time, you should also remember that repairing a toilet bowl can be done with your own hands. However, the issue of repairing a toilet carried out independently should be approached thoroughly. Naturally, first you should study how the toilet flush cistern is arranged inside, as well as the features of repairing it yourself.

Is water flowing between the cistern and the toilet?

One of the problems that arise with a toilet cistern is water leaking between the cistern itself and the toilet itself. If the toilet in your apartment leaks after flushing, then the reason for this may be the connecting cuff, with the help of which the flush cistern and toilet are combined into a single system. In this case, you should carefully check the condition of the cuff.

External leakage of connecting pipes and communications between the tank and the toilet often occurs due to a malfunction of this very cuff. The situation can be corrected by repair, which consists of tightening this element of the toilet with clamps. In case of replacement, the clamps should be selected correctly, in accordance with the material the toilet cuff is made of (plastic or metal). Such repairs should be carried out with your own hands very carefully, so as not to overtighten the bolts or leave them too loose. It often happens that the toilet bowl leaks (photo No. 5).

This happens more often due to the displacement of the corrugated sections of the cuff from the standard position. The best repair option would be to correct the slipped cuff, as well as fix it with a clamp or plumbing insulation of the appropriate parameters (special tape). Note that if the toilet bowl leaks, then using adhesive tape to repair it is a temporary and not very reliable measure. The best methods, of course, are to solve the repair problem using clamps.

The reason that water flows between the tank and the toilet can also be a weak connection between the tank and the toilet shelf (photo No. 6), usually done with bolts and nuts.

In this case, the problem associated with the fact that the toilet is leaking due to poor fixation of the tank can be solved using repairs based on the usual tightening of nuts and bolts. When carrying out the repair procedure, it is important to understand that brass bolts do not deform even when tightly tightened, but metal bolts often require replacement over time, since they are prone to deformation.

If such repairs did not help, and you were unable to get rid of the leak yourself, then you should pay attention to the gaskets. They are located on the tank itself, and you can check their condition by first unscrewing the bolts and nuts. If these structural elements of the toilet bowl are locked or covered with cracks, then they will need to be replaced.

If the gaskets are in good condition, then the best way to update them is as follows. They are dried, and then silicone sealant is applied to the rubber surface, slightly dried again and installed in their original place, tightened tightly with nuts and bolts.

The next reason that the toilet is leaking is various damage to the plumbing shelf (photo No. 7).

The best way out of this situation would be to replace the toilet or replace only the cistern. Such breakdowns often occur due to the dilapidation of the toilet, or due to numerous mechanical damage to the earthenware surface of the cistern. Water seeps through these cracks. The best solution would be to replace the toilet, replace the cistern, or replace all the plumbing.

Another reason why a toilet leaks is water leaking between the flush cistern and the toilet, the appearance of which, in turn, is caused by cracks on the surface of the flush mechanism. Before starting repairs, if the toilet tank is leaking, you must completely disconnect the flush tank from the water supply, thoroughly dry the flush mechanism, and then seal all cracks with silicone sealant, intended specifically for repairing plumbing fixtures, and, in particular, toilets.

This is important! Try to regularly, for preventive purposes, inspect the toilet and all its components (in particular the tank). Such measures will help to detect a problem in a timely manner and prevent the occurrence of a leak. If the flush tank is located high, then it is probably connected to the toilet not only by a cuff, but also by a flexible pipe. Accordingly, you need to check both the cuff and the pipe, because the latter can also leak.

If the drain tank is located low, then in order to prevent water leakage, the condition of the nuts, bolts and gaskets should be monitored. In general, the best option for solving the problem of water leakage would be to completely replace all plumbing fixtures or at least some of its parts.

What to do if it flows through the overflow?

Sometimes apartment owners have to face a problem when water flows from the tank into the toilet. This happens because the water does not have the opportunity to linger and remain in the drain tank. Water flows through the cistern overflow directly into the toilet, creating a lot of inconvenience for the apartment residents. The explanation for the fact that the toilet cistern is leaking is the skew of the float, as a result of which the element is displaced (Photo No. 8).

Repairing such a breakdown is quite simple. You just need to lift the cover and install the element in its original location. The best experts in the field of plumbing repair also advise inspecting the tank for the presence of water. It is quite possible that the water in the tank is overflowing, which is why the water overflows. If, when examining the float, you notice that a lot of water accumulates in it, this fact indicates a breakdown of the element. Repairing it will not be difficult. The best action here would be to carry out several simple sequential procedures:

• Pull out the float;
• Remove the water from it;
• Dry the element thoroughly (you can use a hair dryer);
• Reconnect the float with the fasteners.

This is important! The described measures are temporary, because after some time the water will fill it again. Therefore, it would be better to purchase a new float and replace the broken one.

The float should also be replaced with a new one if the old float valve is damaged.

Repair of a float valve, carried out by replacing an element, is carried out in compliance with an algorithm of certain actions that contribute not only to comfortable operation, but also to the achievement of positive results.

1. The water from the drain tank should be completely drained.
2. Use a wrench to open the shaped area of ​​the structure that connects the water pipe to the float valve.
3. Carefully remove the float lever.
4. Remove the lever fixing elements (outer and inner nuts).
5. Pull out the float valve.
6. Replace by installing a new valve in the free space and securing it with nuts.
7. Connect the float lever to the valve.
8. Fill the tank with water.
9. Fix the float lever as it was done before, before removing the element.

Choosing a good float valve for replacement also involves taking into account the types of element. Of course, you don’t have to pay special attention to this point, because all valve mechanisms have a single operating principle. The float, fixed by a lever, moves up or down depending on the level of water in the tank. The movement of the lever, which opens or, conversely, closes the hole through which water is supplied to the tank, depends on it.

Advice! When choosing a float valve for your toilet, be sure to consider the level of water pressure supplied to the plumbing system.

If this element of the tank is oriented towards low water pressure, then with increasing pressure and high pressure, water will constantly leak through the valve from the water supply, even if the entire system is in full working order.

Note that plumbing components on the market are represented by three types of float valves. Each of them is intended for:

• Water with strong pressure.
• Water with medium pressure.
• Water with minimal pressure.

This fact should be taken into account when replacing one or another model of valve for the float in the toilet tank. If there is uncertainty that the water pressure in the system will be at the same level, or, on the contrary, you are absolutely sure that water will always be supplied to the tank with different pressure, then in such cases, when choosing elements for subsequent replacement, preference should be given to stabilizing valve models.

Such designs are equipped with a piston, which is a hollow mechanism equipped with a stabilizing chamber. It carries water into the stabilizing chamber, which allows the water pressure on both sides of the piston to be balanced.

Damage to the siphon membrane (photo No. 9) is also the reason why the toilet is leaking. If a toilet cistern with a button is leaking due to a similar problem, you will need to purchase a new membrane and replace it. In this case, the dimensions and shapes of the new element used for replacement must correspond to the parameters of the old one.

Such repairs are carried out in the following sequence.

1. Water is completely removed from the cistern.
2. The float lever is fixed to the crossbar.
3. The crossbar is installed instead of the lid, which allows you to stop the flow of water.
4. The nut used to secure the pipe, which allows waste to be flushed away, to the tank is disconnected.
5. The siphon nut located at the base of the cistern is loosened.
6. The siphon is carefully disconnected from the lever that allows you to flush the water, and then it sticks out.
7. The membrane is being replaced.
8. The entire structure is assembled in the same order as disassembly.

When replacing the membrane, you need to take into account the size, shape and dimensions of this element. If, in case of replacement, the siphon membrane has different dimensions from the original, then it is unlikely that it will be possible to eliminate the leak from the tank.

In addition to the reasons discussed above, there are other factors that explain why the toilet is leaking. At first glance they may seem insignificant, but in reality they are not. If there is even the slightest risk of water leaks, then you need to stop flushing the toilet, and then check for yourself the serviceability and correctness of the fasteners, float tubes, nuts and other important parts.

Constant exposure to water causes deformation of all these elements. Cracks, growths, and rotted areas may appear on parts. In this case, either a full repair is carried out, based on replacing the damaged parts with your own hands, or cleaning them from dirt and build-up. The video will tell you in detail about the principles of repairing a toilet and cistern.

Does the toilet leak after flushing?

The question of what to do if water is constantly flowing in the toilet is relevant for many apartment owners. This can happen because the toilet cistern is leaking. If you start flushing the toilet and, after flushing with the button, you discover that water is flowing from under the tank, then first of all you should check the serviceability of the flush device located inside the tank, and if there are problems, carry out repairs.

A likely cause of a leaking toilet tank is a loose shut-off valve that requires repair. The drainage device is located in the central part of the tank, and to correct the leakage situation, you just need to lightly press the drainage valve. If after this the water no longer flows, then the main cause of the malfunction was precisely the loose fit of the shut-off valve. And in this case, the repair will only consist of replacing the gasket on this valve.

Another reason that the drain tank is leaking is the displacement of the height regulator with the drain button. When the regulator is shifted, the valve is installed above the hole into which residual waste products should be flushed with water. Because of this, a gap appears between the drain hole located at the bottom of the tank and the shut-off valve itself.

In this situation, it is not possible to wash off the water in a controlled manner; the water flows in a constant flow and this, in turn, leads to serious excesses in the amount of water consumed. Carrying out repairs in this case is as easy as shelling pears. You just need to set the height regulator with the button to the previous position.

The reason that the toilet tank is leaking may be a poorly tightened nut on the outside of the bottom. When the toilet starts to flush, water seeps through this nut. The repair in this case consists of tightening the nut, as well as checking all the fasteners with which the flush tank is connected to the toilet.

Advice! If a serious breakdown occurs, then it is better not to waste time at all on repairing the tank. It will be easier to replace the repair by purchasing and installing new fastening parts. If the faults are not too large, then it will be possible to carry out repairs using silicone sealant, by replacing old gaskets and correcting the position of bolts and nuts with a regular wrench.

Is the toilet bowl leaking?

Situations when the toilet leaks from below occur quite rarely, and are associated primarily with breakdowns in the toilet bowl. The occurrence of such a problem is caused by improper fixation of the structure on the wall or floor. You can avoid such situations and unplanned repairs if you initially install the toilet correctly (photo No. 10).

In this case, special attention should be paid to the joints and joints of individual toilet elements (water supply and sewerage hoses).

Other causes of leakage

The breakdowns and malfunctions in the operation of the drain tank listed above may not be the only ones. Sometimes it happens that the cause cannot be discovered. In this case, you should take into account several more reasons that may interfere with the normal functioning of the toilet cistern. Some apartment owners have to face a problem when they start to wash away waste with water, but the flush button (photo No. 11) has a problem and does not work.

Note that if a situation occurs with the button on the tank, it falls inside. Because of this, water from the tank constantly flows into the toilet through the overflow. The true cause of the breakdown can be discovered and repairs can begin only after the lid of the drain tank has been removed and the entire drain mechanism has been thoroughly checked.

There are situations when the drain rod jumps out of its usual place, and together with the pressure shutter valve. It should be installed back. In case of such a breakdown, you should also check whether everything is in order with the button. This element can become clogged and must be thoroughly cleaned periodically by first removing it.

The presence of strong water pressure in the water supply can create a precedent when the pressure of this very water is incommensurate in its power with the weak valve of the float mechanism. Due to this problem, a loud noise occurs at the moment when water fills the tank reservoir. Actually, because of this, water flows from the tank into the toilet, moving through the overflow. The peculiarity of the repair in this option will be either replacing the valve with a new and more advanced model (which will withstand strong water pressure), or replacing the conventional valve mechanism with a stabilizing one. As an option, you can consider the process of modernizing the cistern (photo No. 12).

This is done as follows:

1. The cistern lid is removed.
2. The diameter of the hole in the tube, which is the conductor for water into the tank from the water supply, is measured.
3. In accordance with the height of the drain tank, a plastic tube is selected, the diameter of the hole is similar to the conductor tube, with a length of 20-40 cm.
4. Both tubes are connected in such a way that the plastic one does not touch the bottom of the tank. If necessary, it is cut to the required size.

Such a device will serve as drainage for the water entering the tank, and if the water pressure is too high, it will simply suppress it, preventing it from exceeding the norm.

Water from the drain tank may drip due to the formation of condensation on the surface of the structure (photo No. 13).

In this case, you can carry out repairs yourself by eliminating the reasons that led to the formation of condensate drops. This is done like this:

• The inlet and outlet fittings, which are components of the drainage mechanism, are being repaired. If the fittings are broken, then the water flows into the toilet, where it is heated to room temperature. At the same time, cold water constantly flows from the water supply.
• Rinse off with less water than usual. If the toilet is used frequently, then this approach avoids the formation of condensation on the tank. If the drain mechanism is a device with a button, then it should be replaced with a more economical double design or a device with half flush.
• The reason for the accumulation of condensate water on the tank may be an excessive level of humidity in the bathroom. To fix the problem, you need to get rid of all devices that affect the level of humidity in the room.

If a toilet or cistern is leaking in your apartment, then the situation can only be corrected by proper repairs, done with your own hands or with the help of an experienced craftsman. The advice of experienced experts will tell you about the order in which repairs should be carried out and how to eliminate a leak in the toilet cistern.

1. Disconnect the water supply.
2. Unscrew the plastic clip.
3. Dismantle the system through which water is supplied.
4. Remove the old drain mechanism and replace it with a new one. The sequence of actions in this case is as follows:

• Remove the tank fasteners.
• Dismantle the drain element itself.
• A rubber seal remains at the place where the flush tank is attached to the toilet. It needs to be removed.
• Next, the plastic clamp is unscrewed and the entire old drain is completely removed.

1. A rubber seal is put on the new drain mechanism, purchased at a plumbing store.
2. The entire structure is installed inside the tank and secured with a special plastic nut.
3. Next, a rubber seal is installed (photo No. 14).

1. New fasteners secure the tank in its place.
2. The water level in the tank is adjusted in height, and at the very end the flush button or lever is installed (photo No. 15).

If water is constantly flowing in the toilet, then this brings little joy. Intrusive noise makes it difficult to sleep at night, in addition, rust appears in the bowl, and the pipes become covered with condensation.

This is also not reflected in the best way on the water meter readings. Therefore, there is a need to figure out why water is flowing in the toilet, which you can do yourself without involving specialists.

Causes of water leaks in the toilet

There are a number of reasons why water constantly flows from the toilet. To correct this, it is necessary to understand the original source of this negative phenomenon. The following table will help you with this:

Now that you have determined the cause, let's move on to how to fix a water leak in the toilet with your own hands. Depending on the nature of the leak, there may be several elimination options.

The tank is overflowing - what to do?

When water constantly flows in the toilet, not everyone knows how to fix it. The answer is simple: prevent the tank from overfilling.

The following instructions will help you with this:

1. Remove the cover.
2. Raise the float one centimeter. If the leak stops with little effort, the search for the cause can be completed. To fix the problem, you just need to slightly bend the float lever.
3. If the leak does not stop, then it is necessary to inspect the valve itself.. Here you need to make sure that the pin securing the float lever in the valve is intact and in place. At the same time, you will have to check whether the hole that holds the pin has worn out.

1. If the pin is destroyed, it can be replaced with a piece of copper wire (thick). If the pin has simply become loose in the worn hole, then the valve itself must be replaced.

Advice!
When going to the store to buy a valve, do not forget to take the old one as a sample.
There are as many types of valves on the modern market as .

1. The valve must also be replaced if the leak does not stop even with the gasket tightly pressed to the valve hole. Here the problem could be both in the gasket and in the valve body, but since gaskets are not sold separately, you will have to replace the valve itself.

If the water does not reach the overflow level

If water constantly flows in a wall-hung toilet without reaching the overflow level, then the problem can be solved as follows:

1. We make sure that the water flows until the overflow level is reached.
2. We carefully inspect the fittings. If the tank has been in use for several years, then it is best to buy a new set of fittings, the price of which is low.

1. Now you need to completely assemble/disassemble the tank. To do this, turn off the water supplied to the tank.
2. We rinse off the water so that the tank is empty.
3. Disconnect the flexible line.
4. Unscrew the bolts that secure the shelf to the toilet. If they are rusty, they should be cut off using a hacksaw or turbine.
5. Having pushed the tank back, we pull out the shelf from the cuff that connects it to the toilet.
6. Drain off the remaining water, then place the element on a flat surface.
7. The float should not be touched. The rest needs to be disassembled using open-end or adjustable wrenches.

Pay attention!
All rusted bolts must be cut off with a hacksaw.

1. We repeat all steps in reverse order. We replace rubber gaskets even if you decide to keep the old fittings.

How to eliminate a leak if the water in the tank does not go beyond the level and the bolts are intact

In such a situation, the ideal solution would be to replace the pear. It must be unscrewed counterclockwise. The new pear should be the softest in order to block access to water as much as possible.

Advice!
As a temporary solution, a weight can be used that hangs on the rod and presses the pear to the saddle.

Conclusion

As you can see, there is nothing difficult in eliminating water leaks in the toilet. You can both diagnose the breakdown and fix it yourself. You can get more information by watching the video in this article.

One of the reasons for toilet failure is water leakage from the cistern. The nature of this phenomenon has various causes, but in most cases you can eliminate water leakage yourself by carrying out repairs on your own. Indeed, in most cases, malfunctions are of a typical nature, which allows you to quickly find the problem and promptly fix it.

Leaking toilet cistern with button

Models equipped with a button, in addition to all the listed diseases, may have another problem unique to them - the development of the mechanism and the weakening of the release spring.

The appearance of this defect is associated with the mechanism of operation of the drainage system - when you press the button, the drainage process begins, the button is restored to its original position after the mechanism has completely drained the water and released the spring.

Solving the leakage problem in this case is quite simple:

1. Shut off the water supply.
2. Remove the cover.
3. Adjust the mechanism and slightly stretch the spring.
4. After this, check the functionality of the mechanism and, if necessary, make adjustments again.

What should I do to prevent the tank from leaking?

There are few recommendations in this case. First of all, you need to install the toilet correctly and be sure to secure it with mounting screws. A skewed toilet or a toilet with play will itself cause leaks in connections and gaskets.

The second point is related to the need to use modern means of cleaning the tank. Chemical agents allow you to remove lime and rust deposits, which means the mechanism will work longer.

The third thing worth remembering is the need to promptly replace them at the first signs of destruction of rubber gaskets.

Leaking toilet cistern is a common problem that has many causes. Finding out why the breakdown occurred and then trying to fix it is the correct sequence of actions.
