If the toilet bowl flows

It's good to have all the plumbing in the house working properly. However, everything comes to an end once. Parts fail, require repair and replacement. Especially it concerns the problem when the toilet bowl flows. Constant leakage of water leads to large monetary losses, since you have to pay a fairly impressive amount for water. Therefore, such a problem requires immediate intervention of plumbing.

Toilet bowl

If the toilet bowl is faulty, you can easily flood the neighbors from the bottom.

Leaking tank

According to practical experience, plumbers distinguish several main reasons when the tank flows:

  • the petal does not hold water;
  • misses a pear;
  • improperly adjusted float;
  • the fixing bolts have failed;
  • the crane ball is loose;
  • there is no tightness in the hoses.

Sometimes the tank of your toilet bowl flows due to condensation. The reason for the occurrence may be:

Flush tank assembly

The device of a drain tank.

  • the temperature of the tank is much lower than the temperature of the toilet;
  • the room is very humid.

Flushing usually has a moderate frequency. Heating the water tank is too fast, the condensate does not have enough time to have time to fall. In this case, it often happens that leaks flow. Such a tank requires urgent intervention and repair.

First you need to remove the top cover from the tank. The toilet bowl is flowing because of a poorly regulated level. It is necessary to install the float so that when the full tank is being set, the float reliably cuts off the water supply.

Tanks, having an old armature, are repaired fairly simply. It is necessary to bend the lever slightly, on which the float is held. Modern tanks, having plastic parts, are equipped with special adjusting screws.

Causes and problems

Sometimes, a tank flows in connection with a poorly holding pear or petal. To cope with this problem, you need to disassemble the tank. After inspecting all the parts, replace all the damaged ones.

When the tank of a usual toilet bowl flows, in connection with bad adjustment of a float, it is necessary to remove a cover, to define a place of a leak. The simplest repair is ordinary adjustment. However, it happens that the water gets directly into the float. It must be removed, all water removed and the float examined carefully. Rubber over time becomes worthless and begins to flow through the water. In this case, the float must be replaced. It is possible to get water into the float through the seals. If they have lost elasticity and tightness is not observed, they must also be replaced.

Sometimes there is a tank of the toilet bowl due to loose bolting, a toilet bowl and the tank itself. Bolts can be tightened, but this does not always give a positive result. Then the gaskets should be put on the sealant. The cost of the tube does not exceed 100 rubles. However, a large amount of sealant can destroy the "pad" attachment.

In some cases, when the tightness of the hose connection is broken, the tank also flows. For repair, you will need to replace the gasket or the usual tightening of the nut.

Cuff

Scheme of installation and connection of a drain tank

The scheme of installation and connection of a drain tank.

Such a malfunction is considered typical for obsolete structures. The shelf, installed under the bottom of the tank, was made separately and was not connected with the toilet.

In such a case, the cuff, which looks like a truncated cone, may not fit well to the toilet bowl. Sometimes, rubber wears off, it loses its elasticity, starts to crack quickly.

To solve the problem, you need:

  1. If the cuff badly contacts the outlet, simply tighten the rubber with a copper wire of a suitable cross-section. But more reliable will be the installation of a special aluminum clamp.
  2. If the cuff can not be tightened, it must be replaced with a new one. At purchase it is necessary to choose a detail strictly on the sizes of a wrecked lining. It is desirable that the cuff has the maximum elasticity.

To replace, remove the fixing screws, disconnect the water supply and remove the reservoir. For this repair, the flexible hose must not be removed.

The bought cuff should be put on the shelf, after bending the wide edge.

Then the toilet is put in place and bolted. The bent edge of the cuff returns to its place. Such work requires some physical effort. After finishing the work, you need to check the toilet bowl and make sure there is no leakage.

Leakage

The cause of this leak is often a broken bolt. The fact is that over time, metal bolts start to rust, plastic ones burst because of strong tension.

Note that the brass bolts never burst. The cause of leaks should be sought in the tank. Perhaps it formed a crack.

The repair technology is as follows:

  • the water supply is closed;
  • the broken bolt is removed;
  • in the store two bolts are bought, the second one can also burst;
  • The tank is again attached to the shelf; At installation no distortions are allowed.

Gaskets must be installed.

Additional points

A toilet bowl flows, a valve crack appeared.

In this case, the repair has only one possible solution:

  1. The water is blocked.
  2. The float is unscrewed together with the valve. This operation does not require the removal of the tank. You just need to remove the cover, unscrew the clamps and disconnect the flexible hose.
  3. Purchase the necessary spare part.
  4. Carry out all installation work.

Radical way of repair - the toilet bowl flows.

Of course, the best repair of the tank will make a plumber. All repair technology is carried out according to the standard approach:

  • the water supply is switched off first;
  • the flexible hose is disconnected;
  • The valve and the float are dismounted without disassembly.

A thorough examination of the unit is carried out. The principle of work is studied. In details, there should be no cracks or chips. Moving connections should not have any workings. In addition, it is necessary to detect rust and garbage. Bad seal, failed rubber very often cause jamming of parts.

Modern plastic structures for filling the tank very often begin to crack. Brass parts and stainless fittings are covered with oxides. The approach to repair of such parts has characteristic differences. Metal parts can be cleaned, remove unnecessary coating. As a result, their working capacity will be restored. With polymers, everything is much more bulky. Very often cleansing reveals cracks. It is necessary to completely change the whole node.

If thorough cleaning has been carried out, all the channels for adjusting the water supply level have been purged with an air jet, the installation has been carried out, the unit has been adjusted, but the toilet bowl still flows, so the valve itself is very clogged.

Perhaps it has a large production, characterized by a rupture of installed rubber gaskets. It happens that the rubber becomes inelastic.

It is quite difficult to disassemble the valve assembly. This can only be done by professionals. And spare parts for the valve can not be found. Therefore, you just need to replace it with a new one.

When problems occur in the drain valve, the toilet bowl also flows. This is due to the deformation of the drain valve. The plastic began to deteriorate due to the constant presence in the water. Usually its repair and alignment only temporarily eliminate the problem. In connection with this, it is better to immediately replace such a node with a new one.
