Causes of failure
- Water enters the device continuously. This is due to a misaligned float arm or a malfunctioning float valve.
- The membrane in the siphon is damaged.
- The rubber pear has lost its elasticity.
- On the saddle (petal), on which the pear is installed, lime deposits have formed or corrosion has appeared.
- The nut for fixing the overflow is damaged.
- The cuff is leaking at the junction of the toilet bowl and the volume of liquid.
- The rubber seals are worn out.
- Cracks have formed in the drain tank.
- The shut-off valve is defective.
- The knob that controls the height of the drain volume button has shifted.
- There was a breakdown in the fastening of the armature.
Many reasons have been given. Before fixing the leak, find out why the breakdown occurred and take repair steps.
Leak repair
- nuts;
- rubber pads;
- sealant or FUM tape;
- wrench.
Float lever and valve
This issue is being resolved quickly. If the toilet cistern is leaking, the float lever is returned to the horizontal position. In the event of a float failure, there are three options:
- float replacement;
- elimination of breakage with plastic heated to a temperature of 130-170 degrees Celsius;
- wrapping the device in cellophane, thereby preventing contact with water.
The second and third options are temporary measures. Eventually, the defective part will need to be replaced.
Siphon membrane damage
One of the most common causes of leakage, gasket wear
There are two signs of failure:
- liquid from the tank continuously flows into the toilet;
- the drain button works after repeated pressing.
To fix the toilet cistern in this case, change the siphon membrane, following the following procedure:
- Instead of a drain tank lid, a crossbar is placed to which a lever is tied that holds the float.
- Drain the water from the container.
- The fixing nut that connects the flush pipe to the drain tank is unscrewed.
- The siphon nut is unscrewed, after which the device is disconnected.
- Replace the damaged membrane with a new one.
- The assembly of the drain volume fittings is carried out in the reverse order.
Important! The new membrane is selected so that it completely matches the size and shape of the old one. After completing the troubleshooting steps, check for leaks
After completing the troubleshooting steps, check for leaks.
Saddle or pear problem
If the drain tank is leaking due to the loss of elasticity of the pear, the product is replaced. From the saddle (petal), plaque of various origins is eliminated. If you do not remove deposits on the product, then the pear will not fit tightly, causing the toilet bowl to leak.
Elimination of leaks under the tank
The cuff connecting the toilet bowl and the drain volume shifts from its original position over time. In order for the gasket between the tank and the toilet to get into the right position, I tighten it with clamps. If it is not possible to use clamps, adhesive tape, for example, plumbing tape, is used as a temporary method of fastening.
If the toilet is leaking from below, the cause is “bitten” gaskets. Where the toilet bowl is connected to the tank, the fasteners are unscrewed and the integrity of the rubber products is examined. If the gum between the tank and the toilet is damaged (cracked, blocked), it is changed. If everything is fine with the gaskets, they are dried, a sealant is applied to the surface. After that, set to its original position.
Gaskets when repairing a leaking toilet are selected from the following types:
- rubber;
- silicone;
- polyurethane.
Flexible and elastic pads do not leak.If cracks or sagging are found on the surface of the product, do not buy it. Before buying, the gasket is crumpled in the hands: dried parts are set aside, they will not cope with the sealing. The old gasket for the toilet bowl helps in the purchase, they take it with them, which makes it easier to select the part. The price of a gasket for a toilet bowl is on average 500 rubles.
Leaks in the place of fixing the drain volume occur due to malfunctions or damage to the toilet shelf. In this case, you need to replace the plumbing fixture.

The problem is loose nuts. The cause of the leak is sought at the junction of the hose leading from the water supply and the toilet. The nut is tightened, controlling the force. If there are cracks in the nut, the fasteners are replaced with a new one. If there is a problem in the breakdown of the fastening of the reinforcement, it is changed entirely.
The causes of simple malfunctions of plumbing fixtures are eliminated independently. Disadvantages of hiring a plumber include:
- waiting time;
- the employee comes during the working day, so you need to take a day off from work and wait for the arrival of the master;
- financial expenses.
All these inconveniences can be avoided by studying on your own how to fix toilet leaks and familiarizing yourself with the solution to the problem.
