Why is the toilet bowl flowing, letting water into the toilet?

Many plumbing users are faced with a problem such as a leak. Water can leak both in the barrel and in the bowl. This is an unpleasant but fixable situation.

Toilet bowl: its structure and principle of operation

Before troubleshooting and eliminating it is necessary to understand the device and the principle of operation of the tank for draining. Its determining function is to supply the necessary amount of water in order to flush the toilet bowl after use. The material for the tank can be ceramic, if it goes with the bowl, or plastic and stainless steel, if the tank is installed separately. A frequent breakdown of plumbing is that the toilet bowl is leaking water into the toilet.

toilet bowl draws water into the toilet
The tank contains two mechanisms in its device: one takes water, the other lowers it. Both of them perform the function of a water lock. A float- type valve controls the intake of water to a certain level, after which it shuts off its supply. Water can enter the tank either through a flexible hose or through a pipe.

The descent mechanism can be either a pear type or a siphon. The latter makes a loud noise during operation, as the water is drawn by the principle of a siphon, while the water drains when the button is pressed. The second mechanism is different in that when you press the button, the pear rises, and after the water has drained, it again closes the drain hole. So that there is no overflow of water with a pear or separately from it establish protection.

Modern drainage mechanisms allow saving water, since two modes are set on them, allowing not all the liquid to be drained, but only part if this is enough to wash the bowl. But this is not a guarantee that there will not be a problem when the toilet bowl flushes water into the toilet.

Before you start work, you need to check which of the mechanisms is on the repaired tank. At the same time, the toilet lid should be pushed back carefully, since with a possible breakdown it will be difficult to find this element separately on sale.

Many home craftsmen are faced with a problem when a toilet bowl draws water into the toilet. What to do?

Water leak in the tank: possible causes

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

- the toilet flush tank allows water to flow continuously due to overflow;

- leakage in the toilet itself;

- a breakdown in the drain button when it responds only to repeated pressing.

Any of the breakdowns needs to be fixed, you just need to diagnose it correctly.

Mechanically damaged bowl or toilet bowl

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

So, you need to first drain the water, then carefully dry the surface, and then close the crack with a special sealant. But with the bowl, the situation is more serious if a crack has formed in it, for any reason, it will have to be replaced, because there are no repair options.

Water tank overflow

Often the cause of the leak lies in the fact that the float in the toilet bowl leaks water.

Excess fluid is discharged over the edge of the tank. Perhaps the point is the lever of the float, which is slightly moved or skewed. It is necessary to inspect the float, and for this, remove the cover. Its optimal position is 2.5 cm below the nozzle. When the float is deformed, it will not function properly, because water will get into it. Sealant is suitable for sealing a crack in the float, but for this, the element must be pulled out and dried well. Again, the sealant is not a way out, but only a temporary solution, so you will have to buy new accessories.

If the element has no defects, but the water is still poured, then it may be in its pressure. With its high power, the float is pressed by water, which gives it an outlet over the edge. But if a stabilizing valve is provided in the design, a similar problem will not arise.

Constant flow of water into the bowl

Another type of problem when the toilet bowl is leaking water into the toilet is associated with another - when you have to press a button several times to flush. In this case, a malfunction occurs in the membrane. It must be washed with water to remove possible salt deposits.

If this element is deformed and has cracks, then it must be replaced by 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, reinstall the siphon. You should choose a membrane that is identical to the former. When the siphon is removed, other parts must be checked for defects. Often polymer structures become cracked and oxides form on the metal. If the latter can be cleaned, then the plastic is not always subject to restoration, which will lead to a complete replacement of the tank.

Flush button does not respond

The cause of this failure may be a malfunctioning traction. It can be temporarily replaced with wire, and later purchase a new one.

Breakage in the locking mechanism

When the toilet bowl flows, it lets water into the toilet, perhaps the constipation mechanism is broken. This fault cannot be fixed by replacing several parts. You need to buy a whole set of the unit, and not look for parts that are not always sold separately.

The drain button is broken

One of the reasons for the formation of a leak can be a digging on the tank. The return spring may weaken, which will cause jamming in the stem, which will cause a constantly open drain hatch. In this case, the fault can be eliminated by replacing the spring or the button itself.

Leak at the junction with the hose

If a leak has become noticeable where the tank connects to the plumbing flexible hose, then the first way to eliminate it will be to tighten the connecting nut. If the thread is loose, it can be sealed, but a torn thread or a broken hose will have to be completely replaced.

The junction of the toilet and the tank: causes of leakage

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

If a leak occurs in a similar place, the tank should be inspected for cracks. If they are absent, then the cuff remains the probable cause of breakage. She connects the tank and the bowl. It can be made of metal or polymers. The depressurization of the joint contributes to the displacement of the cuff, the troubleshooting is simple - fix the element and tighten. Time may affect this part, so sometimes it requires a complete replacement.

The second version of the problem lies in the rubber gasket, which is located between the bowl and the tank. Incorrect installation leads to its displacement. Over time, this part also fails, cracks and deforms. If there are no changes on it, then it must be carefully put in place and tighten the bolts. Insufficiently tightened nuts on them can cause a leak, but you don’t need to overdo it in this matter, otherwise there is a risk of damage to 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 temperature of the air in the room and the temperature in the tank. This trouble can be eliminated by improving the air exchange in the room, as well as by using a two-level drain.

Output

There are not many reasons for leaking in the toilet bowl. If you know them and follow the instructions for elimination, then not a professional can handle this. The main thing is to act confidently and carefully, then the plumbing will last a long time.
