If a leak is noticed in a plumbing fixture, you need to act quickly. Otherwise, there is a risk of significant financial costs. Consider what to do if the toilet bowl with the button flows after flushing? There may be several reasons for this problem. It is important to establish which part is out of order.

The first step is to determine if there really is a leak. In this case, the sound of murmuring water is noticed all the time, and in the area of its exit - traces of rust and limestone. The inner wall of the toilet closest to the tank is always wet. This is observed, even in the case when they were not used. If the flush is very weak and the water constantly flows into the bowl for a long time, this is also an alarming sign.

Possible causes of a tank leak

The components of the tank are the same in almost all toilet bowls. Differences usually relate to the mechanism of descent of the liquid. Main details:

filling valve. With its help, the water remains at the same level;
float. It helps to close the supply valve (when there is enough fluid);
drain mechanism. It is equipped with an overflow system;
overflow. Controls the maximum water level.

The descent is done manually or with a button. The drain valve opens, which allows liquid to pass through, the float drops. If there are two buttons in the tank, the structure is more complex. At the same time, it differs by saving water by means of partial draining. Now you can buy toilets that have a lower connection for communications. They are used when lateral connection is not possible.

The most common cause is considered to be overfilling the tank. If there is excess water, it accumulates in the drain hole. The problem appears due to the following factors:

Loss of elasticity of the rubber gasket. Due to the long operation of the flushing tank, the blocking of the liquid flow has ceased to be tight. There was a deformation of the gasket and the water began to pass.
The gasket is not pressed enough and poorly covers the inlet, which is located near the drain valve. This results in a leak. The gasket has not lost its elasticity and has not lost its shape. The liquid is passed through only because of the small pressing against the wall.
Rubbing the valve stud holding the float. This happens due to the formation of rust on it and with prolonged use of the toilet.
The appearance of a crack in the valve body through which fluid flows. If it is brass, this problem does not arise, since the material is very reliable. This can only happen on plastic.

In addition to this, there are the following reasons:

The problem appears due to the bolts at the junction of the toilet and the tank. Metal rusts over time, plastic bursts - this leads to breakage.
The failure of the pear, so there is a constant leak in the toilet on the drain. With prolonged use, rubber loses its elasticity. Appears coarsening, the inability to take the necessary form.
Misalignment or displacement of the lever where the float is located. It can be for many reasons: low-quality plumbing parts, a hole through which liquid enters the float, shifting of the lever due to long operation.
Depressurization. Leak between the toilet and tank mount. This is usually due to a change in the shape of the rubber seal.
Stopping channel failure. Because of this, liquid flows from the tank into the toilet.
Crack formation.

Consider the main types:

Imaginary leak. This only happens during the cold months. During this period, the water is very low temperature and after filling the tank, condensation appears. It flows to the floor, and eventually a puddle accumulates. If this is not dealt with, a fungus may form or complaints will be received from neighbors. At a minimum, you should put a rag, wringing it out constantly.
Check valve not holding. The toilet lid needs to be removed. In the case when the button is located on top, it can be connected to the drain mechanism. The problem is in its poor regulation and its violation. If he holds weakly, the liquid flows into the toilet. It is usually enough to change the position of the float lever by lowering the water level.
loosely closed Exhaust valve. To check, it is worth removing the cover and slightly pressing on it. If, due to this action, the flow stops, then the cause has been found and a pear replacement is needed. In some cases, after flushing, the liquid flows, while the tank is not filled. You need to remove the cover and carefully examine the float. It can sink very low, which prevents the valve from returning to its place. It should be adjusted.
Drain leak. You need to drain the water and see where it flows from. If the toilet is inserted into the socket, you need to check its tightness. In the case when its connection to the sewer is made on the corrugation, you should pay attention to the pipeline, if there are any damages.
Broken toilet. Sometimes there are places on the toilet itself that have not been filled with enamel. Then you need to contact the store and make a replacement.

How to eliminate the leakage of the drain mechanism?

These problems are often observed during the operation of the toilet bowl. For a solution, you can call a specialist. But many people successfully eliminate them with their own hands.

It is important to carefully and carefully approach this issue. Before that, you should learn in detail about the internal structure of the toilet drain tank, the types of breakdowns, their identification and repair.

Overfilling the toilet bowl

First you need to find out the cause by lifting the cover, and then the float. It takes 1 cm to stop the flow. This means that the float arm is not bent correctly and the liquid cannot be shut off. It should be slightly bent so that the water flows freely.

If after this the problem is not resolved, it is worth considering the valve. The fixing pin must be in place and not damaged. While in the valve, it suspends the float lever. The hole where this part is localized is not deformed.

In the case when the hairpin has become unusable, it is possible to replace it with a large-section copper wire. If the hole has lost its shape, it is worth installing a new valve.

A leak is sometimes formed due to the gasket. When, after pressing against the valve, the liquid stops flowing from the drain hole, it is necessary to correct the pressure. If this is not possible, a new gasket should be installed.

Take a close look at the toilet. Sometimes only one bolt needs to be replaced. Just in case, you should buy a set of spare parts for the toilet.

To identify the cause, you should disassemble the toilet. It is not always clear which part is broken and needs to be replaced.

The algorithm of actions in this case:

Shut off the fluid supply.
Remove water from the tank completely.
Unscrew the flexible wiring through which the fluid flows.
Loosen the screws. If there is a lot of rust on them, it is worth cutting it off with a hacksaw. Buying bolts from the store will be much more profitable than installing a new toilet. An old toilet is easy to break in the process of unscrewing the rusty parts.
Pull back the tank.
Remove the shelf that is on the cuff.
Drain the remaining liquid.
Remove all rust.

Assembly occurs from the last point to the first. Purchased bolts are being installed, rubber gaskets are being replaced. In the process of tightening, you should not allow even a slight distortion. When tightening, you do not need to put too much pressure on the bolt, there is a risk of spoiling the faience.

Repairing a deformed pear is almost useless. A lot of time and effort will be spent on repairs, but in the end there will be no result. Worth buying a new one.

The choice in the store is best done in favor of the softest option. It can be used for many years until it becomes rigid.

The fastening of the pear is created on the thread. To remove, turn it clockwise, to install - vice versa. Prior to purchase, it is allowed to use the weight that hangs on the stock. There will be pressure on the pear, it is thus pressed against the saddle. You can use any heavy nut.

When buying a low-quality float in a store, it is worth replacing it. If a small hole appears on it, you can easily put it in order with simple polyethylene. Sometimes a piece of plastic is heated with fire and the hole is sealed. This is considered temporary measures, since you still have to purchase a new product.

To solve this problem, you need to put a new gasket between the tank and the toilet. Work execution algorithm:

Turn off the fluid supply by closing the main water valve.
Remove excess water with a soft sponge.
Slightly loosen the drain nut. It is located under the drain valve hatch.
Remove the screws securing the tank to the toilet shelf. Dismantle the tank.
Unscrew the locknut holding the drain, remove it from the tank.
Install a new gasket. All products vary in shape and size, this must be taken into account when buying. If a mistake is made here, the problem will not be solved.
Secure the drain assembly with locknuts.
Return the tank to the stick and fix it with bolts.

Stop valve

The drain valve can be disassembled. To do this, you need to adjust the pressure of the hatch on the drain pipe, slightly undermining the end. These actions require a lot of effort, but the result is not always there. Therefore, it will be more efficient to replace the drain unit or tank.

Step by step algorithm:

turn off the water supply by turning the main fluid supply valve;
wash off the remaining water;
open the lid, remove the liquid with a sponge;
remove screws;
remove the tank from the shelf;
pull out the gasket;
unscrew the lock nuts with which the drain assembly is attached;
remove the old mechanism;
install a new system.

It is worth looking for a model that was previously in the tank. If you can’t find it, then buy a similar manufacturer.

Secure the assembly with locknuts, install a new gasket. Fix to the shelf, turn on the water supply and check the tightness of the installed drain. The work is quite simple, you only need a set of box and adjustable wrenches. The cost of acquiring a new drain will be from 400 to 4 thousand rubles. It depends on the type of mechanism. If the system is elite, the cost is significantly different. For the work of a specialist, you need to pay 1600-1900 rubles.

cracks

Disconnect the tank from the toilet, dry thoroughly. Treat cracks with a quality sealant. This method is the most effective, but such measures are considered temporary. It is necessary to purchase a new tank and toilet bowl.

To fix the tank with the button, you need to act according to the following algorithm:

remove the cover;
take out the broken button;
replace the spring;
center the landing site. It is located under the hole that is made in the cover;
do a reassembly.

Common problems:

The liquid is not washed off when pressed. The reason for this may be a break in the mechanism between the drain channel and the button. They replace the valve with copper wire or purchase a new part.
Leak through overflow. You need to adjust the overflow and the height of the float. To do this, unscrew the nut and change the level.
Continuous flow into the bowl. Usually this happens due to damage to the gasket. Valve replacement required. To do this, unscrew the nut in the lower area of the tank, pull it out, put a new component.

Repair work for a toilet with two buttons is almost the same. If the liquid does not drain, you need to check the parts for integrity, then straighten them or put copper wire. Inspect the drain valve for the correct position, change the height of the overflow or float if necessary.

If the tank has a bottom water connection, they have a diaphragm valve. Problems with it appear due to the weak pressure of the liquid. If the supply always occurs at low pressure, the diaphragm must be replaced with a rod element.

Often a leak is observed in the area of the inlet valve. It is constantly located in the water, so low tightness causes breakage. Repair work for a toilet bowl with a bottom connection is done step by step. First of all, you need to shut off the water, remove the cover. After that, the problem is solved according to the considered algorithms.

To avoid breakdowns, you should listen to a number of recommendations:

clean the tank and bowl once every six months;
periodically inspect the condition of fittings and fittings;
try to avoid mechanical damage, sudden temperature changes;
the installation of the toilet should be approached responsibly. If it is suspended, it is better to call a specialist for this purpose.

It is important to understand that preventive measures taken in a timely manner will extend the life of the toilet bowl. If a leak has formed, first of all, you need to fix minor breakdowns, and then serious ones. To successfully fix the problem, you must carefully follow the specified algorithms and spare no expense for new parts. Otherwise, the situation may worsen.

If you can’t fix the toilet yourself, you should seek the help of a plumber. The issue is resolved in a short time (less than an hour).

Constantly flowing water from the tank to the toilet - this, on the one hand, does not look like a big problem. At least until the liquid is on the floor. But at the same time, you will have to pay large bills for housing and communal services. And finally, it's just annoying.

Fortunately, modern drain systems are simple enough that most problems can be fixed by hand with minimal replacement parts.

Why is water flowing?

The toilet flush system has several weak points. These are nodes with moving elements, as well as sealing zones of various kinds. In a modern tank, a problem can be created by:

float valve system, which is responsible for supplying water and shutting it off;
the place of attachment of the drain mechanics to the bottom of the tank;
sealing zone at the outlet of the main flow of water into the toilet bowl.

If water does not flow outside the tank, most problems can be solved. This will require care and a few simple tools.

Neutralization of breakdowns

In order for the repair process to be understandable and for beginners, not to frighten with unnecessary details in the description of the process, we will outline the possible causes of water leakage in the toilet from simple to complex. We only note the list of works that should always be done so that the repair is easy and convenient:

Shutting off the water supply is a reasonable step, this should be done after the initial check of the valve system.
After removing the water from the tank, you can easily get to the attachment points of the drain system, adjusting bars, and inspect the parts for damage.
Do not dismantle everything at once - checks must be carried out sequentially.

Work with the toilet is best done by carefully wiping and cleaning the inspection sites. This guarantees a good result and an accurate diagnosis of problems.

Valve system

This system consists of:

the valve itself, on which the water supply pipe is screwed;
a float that transmits force to the rod;
the main gasket - a membrane located inside the valve and responsible for shutting off the water.

In such a system, a whole series of problems may arise. To make sure that water is running in the toilet due to poor valve operation, an easy check should be made: raise the float as high as possible with your fingers. If the water continues to flow or has stopped, you need to start repairing.

Float

The cause of the loose valve closing may be a float. When its walls are damaged, water enters. As a result, the part does not float to the desired level, and the liquid overflows over the edge of the emergency outlet tube.

The problem is neutralized as follows: you need to find the place of damage and glue it. If it is significant (for example, a long crack) - the float can be replaced or placed in a strong plastic bag. If there is no damage and water inside, it is reasonable to try to move the floating block lower along the adjustment bar.

Place of attachment to the stem

The adjusting bar, on which the float is fixed, transmits force to the rod. The parts are connected with a plastic pin. It can split and fall out, and the hole where the fastener is located can also be badly broken.

A worn hairpin is easy to replace, you should not use a rusting wire, a piece of plastic or a small wooden chopstick will do. If the mounting hole is badly broken and it is not possible to achieve a reliable water shutoff, it is easier to replace the valve.

valve membrane

If during the initial check (moving the float with your fingers up) the water supply does not stop, valve will need to be replaced., since the membrane cannot be repaired or replaced. Over time, it cracks and loses flexibility, which can cause leakage.

It’s worth going to the store with the valve removed, because today there are such a variety of options that you can only accurately guess the right model by direct comparison.

Dismantling is carried out as follows:

you need to turn off the water supply,
unscrew the underwater hose,
remove the clamping plastic nuts,
remove the float
after that, the valve is pulled out without difficulty.

Cracks may occur in the plastic system. Expensive tanks, where there is a brass knot, do not experience such problems. We note right away: it is useless to glue, try to melt or otherwise repair damage to the valve body, the part must be replaced.

Pear and sealing cuff

The toilet is drained as follows: pressing a button or lever causes a pear with a semicircular tip to rise, after which the main volume of water is released. The part is automatically lowered, pressing against the sealing collar. It is this part of the mechanism that is subject to the action of time. Rubber loses elasticity, cracks may appear.

Seal failure can occur due to bad water. Salt deposits form on the surface of the cuff, and the pear does not close the outlet tightly. Checking the zone is done like this:

you need to activate the trigger mechanism;
after draining the water, the pear should be lifted with your fingers, carefully wipe it and the cuff;
it is necessary to check the elasticity of the seal, as well as the cleanliness of its surface.

You can clean the cuff with a fine sandpaper or file. However, if the part has lost flexibility or cracks have formed, it is better to replace it. To do this, you will have to remove the tank and dismantle the drain system, and how to do this will be described below.

Drain system installation area

Leakage can occur due to wear and damage to the gasket located at the very bottom of the tank, where the main stem of the drain system is attached. Over time, rubber loses its elasticity. In addition, some brass fittings are equipped with iron bolts, which can rust.

A broken threaded rod or cracks in the gasket can only be repaired by replacing the corresponding parts, for which you will have to remove the tank and partially dismantle the drain system.

All work should be done carefully:

The tank is removed after unscrewing the fixing bolts at the bottom. If they are made of plastic, wipe the nuts thoroughly and apply some force. Rusted steel parts can create a problem. It is not necessary to act with a chisel, so as not to split the tank. A wrench, adjustable wrenches, an impeller, possibly a hacksaw will come in handy.
After removing the fixing nuts, the tank is removed and carefully placed on its side.
Using pliers and other hand tools, fasteners are removed that prevent the removal of the drain system. In this case, it is not necessary to dismantle the valve and the float.
After the disassembly is completed, it is enough to purchase parts to be replaced in the store.

Installation of the entire system is carried out in the reverse order and is not difficult.

Conclusion

Repair of any area of the toilet drain fittings is not difficult, it requires only accuracy and care. enough to follow simple rules, avoid distortions in threaded connections, do not apply excessive force to plastic parts, do not rush - and after a while the toilet will again delight with excellent work without the slightest sign of emergency leakage or overflow of the tank.

Plumbing fixtures have become so commonplace in our apartments, houses, offices that their presence is taken for granted.

But some fifty years ago, most Russians did not even imagine that a “latrine” could be arranged inside a house or apartment - almost everywhere they used free-standing sheds installed above cesspools.

And today, malfunctions in the work of plumbing horrify the townsfolk - after all, without a normally functioning toilet bowl, the advantages of apartments are nullified.

One of the most common toilet cistern problems is a constant set of water that occurs due to the fact that water from the toilet bowl flows into the toilet bowl or on the floor of the bathroom (read more about this situation). Naturally, such a state of affairs cannot suit anyone, because it leads to the following consequences:

Unreasonably high water consumption. This natural resource becomes more and more expensive every year, and with the widespread installation of water meters, constant consumption of water leads to prohibitively high utility bills.
Constant noise in the bathroom. Taking into account the acoustic features of our apartments and thin walls that do not differ in high-quality sound insulation, the sound of running water does not contribute to the good mood of the residents, especially at night, when the overall noise level decreases.
Faulty toilet cistern threatens to flood the bathroom with all the ensuing (in the literal sense of the word) consequences, leading to the need to repair the flooring and, in the case of low-quality waterproofing of the interfloor ceiling, the underlying neighboring premises.

Causes of malfunction and methods of repair

What to do if the toilet cistern does not hold water? You need to solve the problem depending on the factor that caused it. There can be several main reasons for constant water consumption.

overflow system

If water constantly and intensively flows from the tank into the toilet through the overflow tube, the following problems may have led to this:

Through the drain

The toilet cistern often leaks water through the drain hole due to such malfunctions:

Other cases

Faults due to which water may leak from the drain tank to the outside. In most cases, the causes of such problems are:

Wear or incorrect installation. In this case, you need to replace or reinstall the rubber gaskets.
Loose threaded connection or its breakage. A neat tightening of the threaded connection or its replacement can correct the situation.
Violation of the integrity of the tank itself, the formation of cracks in it. As a temporary measure, allowing for some more time to operate a broken tank, filling the place of water leakage with a sealing compound can be used. But you still need to look for a new container.

The main areas where leaks can occur to the outside are:

place ;
in the case of a separately placed overflow pipe - at the point of its attachment to the bottom surface of the tank.

In addition to the above factors, the reason why the flush tank does not hold water may be a banal breakage of fragile plastic fittings. This is easy to detect by visual inspection.

Below is illustration showing the main varieties of cistern designs and the name of the control elements:

There is nothing difficult in diagnosing the main malfunctions of the toilet cistern and eliminating them.. Most of the problems can be fixed on your own, even without the use of any tool. Thus, you can save on the call of a plumber and enjoy the successful result of the work.

Is the toilet bowl leaking? Well, let it flow - this is not the biggest trouble. After all, the flowing water will still merge into the sewer. And so do many homeowners. Until they receive a bill for the consumed water.

After that, a belated understanding of the whole danger of the situation comes to them, when your own money flows from the tank into the sewer, almost before your eyes. Therefore, the leak of the toilet flush tank must be eliminated immediately, immediately after the discovery of this defect in the operation of your plumbing equipment. And in this article we will tell you how it is done.

How to fix a leaking toilet cistern if you are not familiar with its design? Of course not. Therefore, before reviewing the repair technology, we will dive into the structure of the object being restored.

A typical tank consists of the following elements:

Float valve (faucet) - a fitting connected to the water supply, on which a shut-off unit controlled by a float is fixed. If there is no water in the tank, the float pulls the shut-off element of the tap down, opening the fitting. When the tank is full - the float rises, closing the fitting.
Overflow - a hollow column connected to the toilet. This column protects the tank from overflow. When the water level reaches the edge of the column, the liquid will overflow into the toilet, and will not rush into the toilet room.
Bleed valve - a hinged hatch covering the drain hole leading to the toilet. If the hatch is closed, then water from the float valve fills the tank. If the hatch is open, then all the liquid accumulated in the tank flows down the drain hole into the toilet bowl.

drain lever - the control mechanism of the drain valve. This unit consists of a rack with a rocker, the edge of which is connected to the valve (hatch) by a polymer or metal chain. By pressing on the free edge of the rocker, you pull the chain up and slightly open the valve hatch. By releasing the lever (rocker), you loosen the chain and lower the hatch into place.

Of all the nodes described above, only the first three elements can provoke a leak in the toilet - a faucet, overflow, valve. Therefore, repairing a toilet cistern leak involves restoring the performance of these particular nodes..

As you can see: there is nothing complicated in the design of the drain system. But enough theory, it's time to move on to repair.

Where to start the repair?

Of course, from the search for the cause of the water leak. After all, only by understanding: why the toilet bowl is flowing, you will be able to eliminate the defect and establish the normal operation of the drain structure.

And there may be several reasons for this, but most often plumbers deal with the following options:

The first option - leakage through the overflow - it is diagnosed very simply - water is constantly flowing in the toilet bowl. As if we have a bottomless structure in front of us, and not a capacity of 10-12 liters (or even less). Therefore - we heard a murmur - get ready to change or repair parts of the float valve.

The second option is a defect in the sealing gasket - noticeable by a constant stream, forming a characteristic lime "drip" on the inner surface of the toilet bowl. We saw him - get ready to dismantle the tank and change the gasket.

The third option is a loose bleed valve - is diagnosed by an intermittent stream flowing from the drain nozzles into the toilet bowl when water enters the tank. Therefore, if water flows from the tank into the toilet during a set of containers, get ready to change the valve shut-off element without options.

As you can see, there are not so many prerequisites for the formation of a leak. However, each of them requires its own approach to repair. Therefore, further we will consider three technologies for eliminating a leak, linked to three reasons for its formation.

The toilet bowl is constantly flowing - what to do?

The reason for the constant overflow of the tank and the liquid leaving the sewer can only be a malfunction of the float valve, which cannot shut off the flow from the water supply.

The simplest reasons for this failure are:

First, float jamming - This defect is eliminated literally within a couple of minutes. To do this, you need to remove the lid and adjust the float lever or move this hollow container away from the edge of the tank. That's all.

Second, float depressurization - this defect involves the elimination of cracks or chips in a hollow container using ordinary glue. You retrieve the sunken float. Drain water from it. Dry the container with a hairdryer and glue the crack with some kind of waterproof compound. Put it back in place and your toilet cistern is no longer leaking.

If the float is not cracked and goes up and down without delay, then you have a more difficult case - a breakdown in locking mechanism the crane itself.

Toilet cistern shut-off valve

And the best way to fix this problem is to completely replace the entire mechanism.

To do this, do the following:

Shut off the water supply to the tank by turning the nearest water valve.
Drain the water tank by pulling the lever or pressing the button/button.
Open the cover, dismantle the float lever and the float itself, if they are not part of the crane design.
Disconnect the external fitting of the faucet from the water supply by twisting the hose fitting.
Loosen the inner sealing nut pressing the tap against the tank wall.
Unscrew the outer sealing nut that secures the valve body in the tank.
Remove the faucet from the tank.
Insert a new float valve into the mounting hole, after screwing the inner nut onto its fitting.
Screw the outer nut onto the part of the tap protruding from the tank and tighten the inner nut.
Connect the water supply hose to the faucet and open the valve.

If the water reaches the level indicated by the float of the tap and does not enter the overflow, you did everything right.

When you go to buy a new float valve (valve) - pay attention to models with stabilizing chambers that level out excessively high pressure in the water supply. Ordinary float valves cannot withstand excessively high pressure and "leak" even when fully operational.

The cost of a float valve (faucet) is 1200-1600 rubles.

The cost of replacing this unit with the hands of professional plumbers is 1400-1800 rubles.

Water flows between the tank and the toilet - what to do in this case?

Leaks in the junction area of the tank with the toilet bowl occur due to depressurization of the joint due to deformation of the seal - a rubber gasket. Therefore, such a leak can only be eliminated by replacing the gasket located between the tank and the toilet shelf.

O-ring replacement

To do this, you will have to do the following:

Turn off the water supply to the tank by shutting off the nearest water valve.
Drain the water from the tank by sinking the lever, open the lid and remove the remaining water with a kitchen sponge.
Loosen the nut on the drain - it is located under the drain valve hatch.
Remove the screws holding the cistern to the toilet shelf.
Remove the tank from the seat.
Loosen the locknut holding the drain.
Remove the drain from the tank.
Replace gasket.

The sealing element - gasket - is available in different formats. Therefore, before replacing, you should clarify its size, so as not to make a mistake when buying. The wrong size gasket will not solve your problem.

Secure the drain assembly with locknuts.
Place the tank on the shelf.
Fix it with screws.

In addition, a leak between the tank and the toilet bowl when draining can be caused by a rusted bolt that secures the container to the bowl, or a crumbled seal that seals the bolt hole.

Of course, in this case, you will have to replace both the bolt and its seal by doing the following manipulations:

Turn off the water and drain the liquid from the tank.
Unscrew the bolts and remove them from the mounting hole.
Insert new bolts into the holes, after putting sealing washers on them, and tighten them by screwing on the nut protruding from the shelf.

The cost of laying is about 200 rubles.

The cost of a set of bolts is from 50 to 300 rubles.

The cost of replacing bolts and gaskets is 1200-1400 rubles.

In some cases, a leak between the shelf and the tank can be eliminated by simply tightening loose bolts. To do this, fix the nut on the outlet with a wrench and tighten the fasteners with a screwdriver.

However, be careful - sanitary ware is not as durable as it seems. One has only to squeeze the bolt a little, as a crack will appear in the bottom of the tank. Therefore, do not abuse this advice - it is better to change the gaskets.

How to fix a leak in the toilet bowl with a faulty shut-off valve?

In this case, you can try to disassemble the drain valve and adjust the degree of pressure of the hatch to the drain pipe by sharpening the end of the latter. However, this recipe is associated with a lot of labor and does not always help.

Open the tank lid and adjust the shut-off valve

Therefore, it is better not to even undertake repairs, but simply replace the entire drain assembly, proceeding as follows:

We disconnect the toilet room from the water supply manifold or simply turn the central valve near the meter.
Flush the water into the toilet, open the lid and remove the remaining liquid with a sponge, squeezing it directly into the toilet bowl.
We unscrew the fixing screws, remove the tank from the shelf.
We dismantle the sealing gasket, unscrew the lock nuts holding the drain assembly.
We dismantle the old node and insert a new one, bought in advance, in its place.

When purchasing a new drain assembly, try to buy exactly the model that was in your tank before, or at least from the same manufacturer. That is, if your cersanit toilet bowl is leaking, buy a drain unit of this particular brand.

We fix the assembly with lock nuts from the new kit and mount a new gasket.
We put the tank on the shelf, insert new or old bolts into the holes.
We fix the tank on the toilet shelf.
We connect the water and check the tightness of the new drain mechanism.

As you can see: the problem is solved by fairly simple manipulations with box or adjustable wrenches.

At the same time, the cost of a new drain mechanism ranges from 400 to 4000 rubles, and sometimes even more.

Work on replacing the drain mechanism will cost you 1600-1800 rubles.

What to do if the toilet cistern with a button is leaking?

First of all, check the position of the switch. After all, the button can sink in its shaft due to jamming of the stem or weakening of the return spring, as a result of which the drain cover will lock in the “open” position.

Toilet cistern design with button

Button repair involves the following steps:

Removing the cover.
Removing the sticky switch.
replacing the spring or the entire button.
The centering of the seat - it should be located immediately under the hole in the cover.
Reassembly - return to the place of the cover and button.

What to do if condensate flows from the tank?

This happens if very cold water flows into the container, and an excessive level of humidity is observed in the toilet room. But you can eliminate this problem by providing pipe heating or increasing the ventilation rate of the toilet room.

The latter way is more preferable, since it guarantees the elimination of perspiration on the outer walls of the tank without energy costs. Indeed, to increase the multiplicity, you need to expand the exhaust hole or mount a pressure unit there - a fan.

In one day, up to 40 liters of water escapes into the oceans if you have a toilet leak in your apartment. In a month, this number adds up to fabulous utility bills. It is clear that any owner is interested in fixing problems in the toilet as soon as possible. To do this is not always as difficult as it seems, however, the failure of fittings can be confusing for many.

Toilet flush mechanism: how it works

For many years, the standard set of filling kits has remained the same, because the mechanism itself has not undergone revolutionary changes. In a professional environment, the operation of the drain tank is based on the principle of a water seal:

Attention! Be extremely careful when working with the ceramic lid. It is not sold separately, but it can crack or break if it falls to the floor.

Why is it leaking from the tank. Troubleshooting

The probable reasons that water is leaking from the tank can be:

depressurization of the toilet float;
breakage or incorrect operation of the shut-off valve;
failure of the rubber gasket and leakage at the point of descent of water.

In the first two cases, water will continuously flow into the tank and pour out through the overflow safety hole in the upper part of the drain mechanism. In the third - to seep in the squeezed or crumpled place of the gasket and leak from the tank into the bowl. There are different ways to solve these problems, so it is important to correctly diagnose the breakdown. Do this simple experiment:

Attention! Modern toilets are most often equipped with plastic fittings, which are not durable. The service life of the tank filling is also affected by the quality of the water. If it is low, and the liquid is not filtered when it enters the home plumbing, then an aggressive mixture of substances will eat away the plastic components.

How to fix a toilet if it leaks water through the overflow

You can most often fix typical problems with the float and valves yourself, without buying additional materials. For any repair, you must first turn off the water supply to the toilet.

The float was warped. This mechanism is constantly in motion, therefore, after several years of service, its connections become loose, backlashes appear. The system needs to be re-balanced: return the float to its normal position and tighten the dangling elements.
The float has depressurized. If water penetrates the hollow glass of the float, wrapping it in a regular plastic bag will help in the first case. You can also solder an unnecessary hole with plastic. But such repairs are short-lived. Get ready to buy a new valve mechanism.
The shut-off valve does not close due to a loose float pin. Re-insert it into the slots. If it breaks completely, attach the float with a copper wire bracket. It won't help for long, but it will last for a while.

Advice. It is better not to use steel products inside the toilet bowl. Rust will eat them.

How to fix a tank drain

Eliminating such a cause of leakage from the tank is more difficult. Most likely, you will have to go to a specialized store. Faults and how to fix them:

Siphon membrane damaged. This device is found in older models of toilet bowls. The siphon can only be replaced. Remove the cover, disconnect the fitting, unscrew the nuts and replace.
The rubber pad has lost its elasticity. Usually it bends under constant water pressure and loses full tight contact with the saddle. Sometimes weighting the device helps - a pair of stainless steel nuts is placed on the vertical overflow tube. But this is a temporary measure. It is better to replace the gasket with a new one. Although here, too, a trick may await you with the selection of a similar part - it simply may not be on sale, and the entire drain mechanism will have to be changed.
The surface of the saddle is covered with rust or lime deposits. This also leads to leakage. Clean the surface thoroughly. With hard water, this is recommended every few months for prevention.

Going to the store, do not forget the old part. So the consultant will help you choose a similar one. To repair the toilet, no special tools and tools are needed. The main thing is to correctly identify the malfunction. Even a person who does not have experience with plumbing can eliminate leakage from the toilet bowl.
