The toilet bowl flows - what should I do? Repair of the waste tank

Buying plumbing, we want it to serve for a long time. But operating conditions can sometimes lead to such troubles as water leakage. And most often it happens with the toilet bowl. In addition to the increased bills for water, the flow of water leads to the formation of rusty spots on the toilet and, in time, the appearance of a urinary stone. For the premise the raised level of humidity can become the reason of formation of a fungus, a mold, and it already serious threat to health of the person. So what to do when the toilet bowl is leaking? First, let's look at the design of this plumbing.

The device of a tank of a toilet bowl

Any toilet bowl tank consists of the following parts:

• float;
• A float spoke;
• A cover of a siphon;
• Rubber gasket for sealing;
• Connecting ring;
• Diaphragm lever;
• Ball valve;
• The lever of adjustment of a stream;
• metal plate;
• Plastic diaphragm;
• Adjacent drain pipe;
• water pipe;
• Fastening elements of the barrel to the toilet.

It does not matter what year the discharge tank is. The principle of operation remains the same. To understand why the toilet bowl is leaking, we will analyze how types of devices exist and how they function.

Kinds

There are several classifications:

• According to the location of the mechanism of water launch: lateral, upper. It can be buttons, chains, levers. There were models with two buttons, which allow draining water in the usual mode and economical.
• According to the material of the tank: metal (most often cast iron), plastic, ceramics.
• By the way of installation: a compact (toilet and a tank are fastened together), stand-alone (can be used for retro design, or meet in old houses), hidden (the whole installation hides in the box, toilet pendant).
• Flushing method: direct, reverse.
• The place where the valves for the waste tank are located. There is an upper and lower location.

Regardless of which device is the toilet bowl and what classification it belongs to, the algorithm remains the same.

Mechanism of action

According to the principle of operation, the tank is a complex of a filling and draining system. The water enters the storage tank through the water pipe. The level is determined by the float. Having reached the required volume of liquid, the stop valves stop the water supply.

The drainage system starts to work after the mechanical action on the button (lever, chain). At this point, the valve opens and the right amount of water flows into the toilet bowl. And then the filling system is switched on in a circle. How to understand why the toilet bowl is leaking? Let's look further.

Visual definition

The repair of the drain tank begins with a fault finding. This may be the appearance of water near the toilet, a weakly functioning drainage system, a constant flow of water. The appearance of puddles near the plumbing indicates that the sealing is broken. To do this, inspect the location of the water pipe to the tank. Most often this is the reason. The next step is to check the condition of fastening the toilet bowl to the storage tank. Another option is that the rubber gasket in the place of water supply to the drain is deformed and loosely closes the hole. A weakly functioning drain system indicates a blockage of this mechanism or a problem with the membrane.

The constant flow of water into the toilet can be caused by several reasons. Let's consider each kind of failure separately and how in a particular case to carry out repair of a drain tank.

Water supply

The frequent problem of the appearance of puddles near the toilet is the depressurization of the connection of the water pipe and the tank nozzle. In modern models there are plastic components. Therefore, during operation, the thread can be erased and thus the sealing is destroyed. This problem is eliminated very simply. Shut off the water supply shut-off valve. The rounded hose is wound on a flax thread or a fumble. Back tighten. If the leak has stopped, the problem is eliminated. If not, repeat the procedure by increasing the layer of sealing material. Another reason is a crack on the plastic fittings. In this case, it should be replaced with a new one.

Rubber gasket, fastening

In both cases, the lid is removed, the valve for the tank is taken out. The rubber gasket is checked for deformation. There may be two options:

• Loose fit. Repair the position, and reassemble the tank.
• Deformation in the course of operation. To be replaced with a similar product.

The fixing of the tank to the toilet bowl may eventually become loose, break down under the influence of rye. Therefore, leakage is lost, or the rubber sealing gaskets wear out. In the first case, you should tighten the bolts and replace the seals, even if they are not deformed. In the second, change the seals.

Drain valve for toilet bowl

In this case, experts recommend buying a new one and installing it. If the decision is made to repair the existing one, it should be dismantled and the clearance between the drain hatch and the branch pipe adjusted. For this, file the last. To do this work, it is necessary to be patient. Otherwise, the failure will not be fixed. Therefore, it is recommended to replace the old flush valve for the toilet bowl with a new one. There is another situation. Very often the reason for the toilet tank leaking is a crack on the valve body. In such cases, it will be simpler and more economical to replace the old one with a new one. For this, the cracked part must be taken with you. Because the modern plumbing market offers a wide range of drainage mechanisms.

Sealing cuff between the tank and the toilet seat

In such cases, the fixing bolts are loosened, the tank is removed. The cuff can be plastic, metal, rubber. In the process of operation it can:

• Move. In this case, it must be corrected.
• Deform. Replace with a new one.

Then the tank is installed into place. To increase the level of sealing, you can walk around the joint with silicone sealant.

Float

Often there is a situation where the toilet bowl is leaking due to improperly adjusted position of the float. There may be several reasons:

• The lever of the float has moved and clings to anything. Output, correct, check serviceability.
• The position of the float is not adjusted. The device slightly lifts the hands. The leak is gone-fix the position. In some devices this is done by bending the float knitting needle, in modern devices it is due to thread regulation.
• Float integrity is broken. You should pour the water out of it and put it in a bag. This is a temporary solution. For capital - it should be replaced with a new one or the hole is sealed. Fortunately, the range of glue this allows you to do.

Problems with the float are often the reason when water constantly flows into the toilet bowl from the tank. Apparently, it's quite simple to solve it. What if the manipulations with the float did not give a positive effect? The cause may be failure of the shut-off valve. In such cases, the design changes completely.

Siphon

Most often, the failure of such a plan is due to deformation of the membrane. The water supply is blocked. The storage tank is emptied, the valve for the tank is taken out. Unscrew the nuts of the siphon, the membrane is removed. Visually verified for integrity and deformation. If necessary, a new one is purchased and replaced. The old product should be taken to the store. This will help to choose the right part from the abundance of assortment. A damaged membrane can serve as a reason for the inoperative drain button (when water starts to flow into the toilet after a few clicks).

Jamming the button

With this failure, the sink is fixed in one position. Therefore, the toilet bowl flows. What to do in this situation? The lid is removed, it is checked because of what the mechanism jammed. Often the plum mechanism is checked for the following features:

• System clogging. Cleared from plaque.
• The wedge sticks. The cause of jamming is identified and eliminated. If necessary, change to a new one.
• The return spring was loosened (the connecting ring was deformed on the lever). To be replaced.
• The traction system has broken or deformed. It can be made from improvised means, for example, wire. But this will be a temporary solution to the problem. Because during the subsequent operation the wire will bend over time and it will be necessary to repeat the procedure anew.

Of course, until the failure is eliminated, the water supply system should be shut off, draining the liquid from the drain tank.

Features of plumbing repair

As a rule, the device of a drain tank and its installation to a toilet bowl does not differ special complexity. Therefore, you can easily repair yourself. But we must remember a number of important points:

• Do not over tighten the fasteners. Otherwise, the plastic fasteners will just burst. A tug of metal can lead to the fact that the tiles themselves tiles plumbing.
• If you want to change a part for a new one, take the old one with you to the store. This will save you extra running, in case you purchased the wrong part by eye.
• The cost of the parts for the waste tank is not high. But the call of a locksmith will add a considerable amount. Therefore, it is better to repair by yourself.
• Timely repairs will avoid such problems as the flooding of neighbors.
• Before starting repairs, it is essential to shut off the water supply system.

The simplicity of the mechanism will not cause special difficulties even for the most inexperienced locksmith. Therefore, armed with patience and ingenuity, you can eliminate the leakage of the tank by yourself. Moreover, this does not require a serious tool kit.
