Leaky toilet tank always causes a lot of problems. It starts to spoil the mood, irritating the noise of continuously flowing water. On the water meter there are large numbers, you have to pay for water several times more. The surface of the toilet starts to become rusted. Condensate droplets become noticeable on the pipes, which can lead to corrosion, mold formation. The leakage of the tank must be immediately eliminated in order to avoid the appearance of negative consequences. Today, the resulting leak in the toilet bowl can easily be corrected without resorting to the services of specialists. But for this it is necessary to understand the principle of the operation of such a system and its components.
Design of toilet tank
To repair the toilet bowl, you need to very well imagine what elements it consists of and how it works. The market offers a variety of different models. Consider the most common.
The most common types of flushing cisterns for toilet bowls are structures combined with a bowl (compact) and hanging ones. The first are convenient because during installation it is not necessary to mount a special outlet pipe.
And secondly, a stronger pressure is created, so that the bowl of the toilet is better cleaned.
To the disadvantages of suspension tanks can be attributed a stronger noise when flushed, and additional elements complicate the design, because of which the risk of breakage increases.
However, in general, they are no less convenient and practical than those with a bowl, so in modern apartments are very common.
Now, when aesthetics is becoming an equally important criterion for choosing plumbing as a convenience, many apartment owners began installing installations.
The drain tank of this model is mounted in the wall, and it becomes invisible. For flushing there is a special button on the panel.
Because of the hidden installation, this design is a little more difficult to repair, if something happens to it.
Triggers can also differ, and this often depends on the convenience and durability of operation.
For closed drain tanks, the water release buttons are most often used, but there are designs with chains or levers that are installed for hanging models.
The mechanical triggers are designed so that the water drains off while the button is pressed, and the automatic ones are triggered even after a one-time short press. Breakdowns in the mechanisms of the first type are less frequent, but the difference is still not of principle; both types are quite reliable.
As for the material, the most common models are ceramic and plastic, although in some apartments cast iron rarities can still be found.
Plastic and faience tanks are very convenient, they rarely burst. Usually the cause of their failure is mechanical damage or factory marriage. You could find toilet leaking from bottom of tank if there is so.
The most common types of faults and their elimination
The following are the most common problems, which are expressed by the following signs: continuous flow of water from the water pipe into the drain tank;
- continuous flow of water from the water pipe into the drain tank;
- water constantly flows into the toilet bowl from the tank;
- draining of water occurs only after repeated pressing of the button or lever;
- the flush button does not work;
- Toilet tank running too noisy.
In each of these cases, it will not be difficult to repair the toilet bowl. The main task is to understand the cause of the malfunction and method how to fix leaky toilet tank.
How to eliminate leakage
If the water constantly flows in the toilet, the leverage of the float has probably skewed or shifted. To fix the problem, you must bring it to its normal position. Usually it is located 2.5 cm below the entrance of the underwater pipe.
To find out why the water flows in the toilet, it is sometimes enough to inspect the float. If it is damaged and water accumulates inside, the float will become too heavy. To fix leaking toilet tank is simple: Remove the float. Pour water out of it. Close the hole. Reattach the float. The hole in the float can be sealed with a heated plastic or a conventional plastic bag, which must be firmly fixed to the float. And, frankly, such repairs can only be considered as a temporary measure. In the next few days, you need to buy a new float and install it instead of the damaged one.
If water comes in continuously or flushes up only after repeated pressing of the button, it is necessary to replace the siphon membrane. Proceed as follows: Install the crossbar instead of the lid. Tie the float lever to the crossbar. Drain the water from the tank. Remove the fixing nut that connects the tank to the flush pipe. Loosen the siphon nut. Disconnect and remove the siphon. Remove the damaged membrane and install a new one, identical in size and shape. Install the valve in the reverse order.
If the drain tank button does not work
If the drain tank button does not work If the flush button does not work, it is usually necessary to repair the damaged traction. To do this, you need to detach the broken element and make a new one, for example, from a piece of thick wire. Later, you can replace it with a new traction to ensure the normal operation of the toilet for the longest possible period.
If the water rushes when filling the tank
Very unpleasant things can be too noisy filling the tank when water flows in the toilet, especially if these sounds interfere with the normal night rest of the residents of the house. The simplest way to solve the problem is to make a silencer. To do this: Take a flexible tube of plastic. Install it vertically with respect to the water level at the entrance to the float valve. The lower end of the tube should be placed under water. If the silencer from the plastic tube does not help, you need to install a stabilizing float valve that adjusts the water flow into the tank. For some faults, the entire drainage system must be replaced.
The valve does not work
The defective trigger valve can become another cause of leakage. Check it is possible as follows: if the water is slightly moved or when it is not closed, repair is required. The problem can be in a worn out rubber band or a blockage. It is easy to remove it yourself. But there are cases when the replacement of one part and cleaning from debris do not help, then a locking mechanism is installed.
Replace the bolts in the leaking toilet bowl
Most models of toilet bowl tanks are attached to the shelf using bolts that pass through the bottom of the tank. Metal bolts are corroded and can rot away after a while. Water in this case will leak through the holes, toilet leaking from tank onto floor. You could find toilet leaking from tank bolts as well.
What to do if toilet tank bolts leaking:
- Close the tap of water supply to the tank.
- Drain the remaining water from the toilet bowl.
- Dismantle the inlet valve of the tank.
- Dismantle both connecting bolts securing the tank to the toilet bowl.
- The tank is on the rubber cuff. We raise the tank and remove the cuff. If necessary, replace it.
- Clean the junction points, free them from dirt.
- Assemble the equipment in the reverse order with the insertion of new bolts. When tightening the bolts, do not use excessive force so that the sanitary ware does not burst.
- Check the efficiency of the reservoir and the absence of leaks.
