Why does the toilet bowl flow, lets water into the toilet?

Many plumbers meet with such a problem as leaking. Water can leak out both in the barrel itself and in the bowl. This is an unpleasant but reparable situation.

Toilet bowl: its structure and operating principle

Before troubleshooting and troubleshooting, it is necessary to understand the device and operation principle of the drain tank. Its defining function is to supply the required amount of water in order to rinse the toilet bowl after use. The material for the tank can be ceramics if it comes with a bowl, or plastic and stainless steel, if the tank is installed separately. A frequent breakdown of plumbing is that the toilet bowl passes water into the toilet.

The tank contains two mechanisms in its device: one takes water, the other descends it. Both of them serve as a water seal. The float valve controls the set of water to a certain level, after which it blocks its supply. The flow of water into the reservoir can take place either via a flexible hose or by a branch pipe.

The mechanism of descent can be either a pear-type or a siphon. The latter, when working, emits a loud noise, since water is recruited according to the siphon principle, while the water is drained when the button is pressed. The operation of the second mechanism is different in that when the button is pressed, the pear rises, and after the water has drained, it again closes the drain opening. In order not to overflow water with a pear or separate from it set protection.

Modern drainage mechanisms allow you to save water, because they are installed two modes, which allow you to lower not all the liquid, but only a part, if this is enough to flush the bowl. But this is not a guarantee that there will not be a problem when the toilet bowl passes water into the toilet.

Before you begin to work, you need to check which of the mechanisms is on the repaired tank. At the same time, the lid of the toilet bowl should be moved carefully, as with a possible breakage it will be difficult to find this item separately for sale.

Many home craftsmen face the problem when the toilet bowl passes water into the toilet bowl. What to do?

Leaking water in the tank: possible causes

If the plumbing is installed recently, it may leak due to improper installation. If, after the start of use, only a few months have passed and a malfunction has already appeared, this is most likely due to the poor quality of the hardware and, as a result, to premature failure. Serious breakdowns, because of which the toilet bowl passes water into the toilet, do not occur often. They can declare themselves only after three years. The main ones are:

- the toilet flush tank passes water continuously due to overflow;

- leaking in the toilet;

- failure in the drain button when it reacts only to repeated pressing.

Any of the failures is subject to correction, you just need to diagnose it correctly.

Damage by mechanical means of a bowl or toilet bowl

Cracks in the plumbing appear for several reasons. Most often this is incorrect installation, or the expiration date of the product. Excessively tightened bolts at the junction of the tank and the bowl will cause the ceramics to crack. If cracks penetrate the drain tank, then it can only be repaired temporarily, but this is enough to buy a new one.

So, you must first drain the water, then carefully dry the surface, then seal the crack with a special sealant. But with the chalice the situation is more serious, if it formed a crack, for any of the reasons, it will have to be replaced, because there are no repair options.

Water tank overflow

Often the reason for the leak lies in the fact that the float in the toilet bowl passes water.

Excess liquid is drained over the edge of the reservoir. Perhaps the thing is in the lever of the float, which has shifted or twisted slightly. It is necessary to inspect the float, and to remove the cover. Its optimum position is below the nozzle by 2.5 cm. If the float is deformed, it will not function properly, because water will enter it. To seal a crack in the float sealant, but for this, the element must be pulled out and dried well. Again, the sealant is not a way out, but only its temporary solution, so you'll have to buy a new hardware.

If the element has no defects, and the water is still poured, then there may be a case in its head. At its high power, the float is pressed with water, which gives it an outlet over the edge. But if a stabilizing valve is provided in the design, a similar problem does not arise.

Constant water intake in the bowl

Another kind of problem, when the toilet bowl passes water into the toilet, is interfaced with the other - when the flushing has to press the button several times. In this case, a fault in the membrane. It must be rinsed with water to remove possible salt deposits.

If this element is deformed and has cracks, then it must be replaced, proceeding as follows: at the bottom of the barrel, find the siphon nut and loosen it, then remove the siphon itself. After replacing the membrane, install the siphon in its original position. It is necessary to choose a membrane that is identical to the previous one. When the siphon is removed, it is necessary to check other parts for defects. Often, polymer structures are covered with cracks, and oxides form on the metal. If the latter can be cleaned, the plastic is not always subject to recovery, which will lead to a complete replacement of the tank.

Does not respond to the flush button

The cause of this failure could be a faulty traction. It can be temporarily replaced with wire, and later purchased a new one.

Breakage in the locking mechanism

When the toilet bowl flows, it passes water into the toilet, possibly the mechanism of constipation is broken. This fault can not be eliminated by replacing several parts. You need to buy a whole set of nodes, rather than look for details that are not always sold separately.

Broken drain button

One of the reasons for the formation of leaks may be a digger on the tank. The return spring can be weakened, which will cause jamming in the rod, which will cause a permanently open drain hatch. In this case, the problem can be solved by replacing the spring or the button itself.

Leak in the joint with the hose

If it becomes noticeable to flow where the tank is connected to a water flexible hose, the first way to eliminate it is to tighten the connecting nut. If the thread is weakened, it can be sealed, but the broken thread or the broken hose must be completely replaced.

The place of the joint of the toilet bowl and the tank: the causes of leaks

If the toilet bowl passes water into the toilet, replacing the gum can help at the junction of the tank and bowl.

When leakage occurs in a similar place, inspect the tank for cracks. If they are absent, the probable cause of breakage is the cuff. It connects the tank and the bowl. It can be made of metal or polymers. Depressurization of the joint helps to move the cuff, eliminating the malfunction is simple - fix the element and tighten. Time can affect this part, so sometimes it requires a complete replacement.

The second variant of the problem lies in the rubber gasket, which is located between the bowl and the tank. Wrong mounting leads to its displacement. Over time, this part also breaks down, crackles and deforms. If there are no changes on it, then it must be neatly put in place and tighten the bolts. Insufficiently tightened nuts on them can cause leakage, but you do not need to overdo it, otherwise there is a risk of damaging the ceramics.

Condensate

Often a wet spot appears under the tank due to the formation of condensation on its surface. This is due to the fact that there is a difference in the air temperature in the room and the temperature in the tank. Eliminate this trouble by improving the air exchange in the room, as well as in the use of a two-level drain.

Conclusion

There are not so many reasons for the leak in the toilet bowl. If you know them and follow the instructions for removal, then even a professional can not cope with this. The main thing is to act confidently and accurately, then the plumber will serve for a long time.
