Well, when the bathroom is working properly, and nothing in it does not cause problems. But over time, this system may malfunction, and it is good if they touch only the owners, because the problem can reach the neighbors from the bottom, which is highly undesirable.

The most frequent problem that occurs in the bathrooms, concerns a leak in the toilet bowl, and the first thing you want to do in this case is the call of the master. But this can be avoided if you know how to change the gasket in the toilet. How to do this, and will be discussed in this article.

The lining established between a toilet bowl and a tank.

Cistern structure

The components that make up the drain tank.

For several decades, the drain tank device has undergone a minimum of changes. As well as half a century ago, a float is raised parallel to the filling, resulting in a blockage of the water flow.

The work of modern drain systems is provided by three components, which include:

  1. Float.
  2. Leverage.
  3. Gasket

The operation of the mechanism is as follows: when it enters the tank, water, when it reaches a certain level, is blocked by means of a check valve. When you press the drain lever, the water is drained.

The main malfunctions arising in a drain tank

In the occurrence of a leak is not always to blame for the lid of the toilet bowl. Therefore, before starting to work, you need to determine the nature of the leak. The following table will help you with this.

Leaking in the toilet is not always the fault of the gaskets. In the photo - setting the level of the float.
Type of fault Cause Remedy
Water enters the tank continuously. There may be several reasons for this phenomenon:
  1. Skew float lever.
  2. Damage to the float lever.
  3. Poor operation of the float valve.
 The problem is solved by installing the float horizontally (when it comes to misalignment) or replacing it. If there is no possibility for replacement, then for a while you can tightly wrap the float in a plastic bag to protect it from water.
Do not stop the flow of water in the toilet. Most likely, you have a damaged drain valve membrane. The problem is solved by replacing the membrane. To do this, it is necessary to disconnect the drain pipe from the product, after which the membrane is replaced. Also here you need a new gasket under the toilet bowl.
Leaking tank. The reason for this may also be:
  1. Pear lost elasticity.
  2. The appearance of corrosion and limescale on the basis of the pear or its saddle.
 In the first case, the leak is eliminated by replacing the pear. In the second, you need to detach the pear by cleaning its saddle with sandpaper. Your goal in this case is to eliminate corrosion and deposits.
Leak between the cistern and the toilet. This problem can also be caused by the fact that the gasket between the cistern and the toilet has cracked or has been incorrectly installed. Technicians call this phenomenon "zazhevannoy gasket." First of all, you should check the rubber lining under the toilet. If it is installed incorrectly, give it the correct position and reconnect the structure. If the reason is that it is cracked, then it needs to be changed. The price of gaskets is low, and therefore such a replacement will not hit your wallet.
Water flows out. The reasons for this problem may be several:
  1. Loose nut fixing the tank to the toilet.
  2. Crack in the nut.
  3. The occurrence of cracks in the tank due to mechanical damage or marriage.
 In the first case, you only need to tighten the nut. This is a fairly frequent problem of such leaks.

Cracked nut must be replaced.

If you find a crack in the tank itself, then you need to change it.
Water leaks from the tank. This may be due to an incorrectly set button height at which the valve is above the drain hole. Because of the gap formed and leakage occurs. The problem is eliminated by adjusting the height of the button.
Water leaks in the toilet when filling the tank. Most often this occurs due to the fact that the shut-off valve simply does not shut off the water. The first step is to install a valve defect. To detect it, push the valve down with your hand - the water must stop flowing. If this is so - changing the gasket for a suspended toilet with their own hands. If this does not work, change the valve.

Replacement toilet bowl

Assembly of sanitary products. Lining set correctly.

Tip: the more flexible the new gasket, the less likely the leak.

If you have an old toilet, then sooner or later it will have to be changed.

And the following instruction will help you do the right thing:

  1. First you need to determine the form of release, which can be horizontal, floor or slant. You need to acquire the type of product that you had before.

Note! If you choose a simpler and cheaper model of the tank, then in case of breakage it will be more profitable to replace the entire float system. If the model is more expensive and rare, it is better to stock up on spare parts.

  1. The simpler the tank design will be - the plumber will be more durable.
The simpler the reinforcement, the less likely it is to fail.
  1. Do not forget to purchase an additional set of gaskets, In this case, when a leak is detected, you will not need to go to the store, and you will be able to quickly resolve the malfunction.
Different types of sanitary pads, which should always be at hand.
  1. If you do not have experience in changing the toilet, it is best to trust a specialist.
