Not a single apartment or private house can do without installing plumbing . It happens that malfunctions occur in her work, for example, a toilet bowl flows. What to do in this case, how to solve the problem, is described below. It is very important that all repairs can be done independently.
Toilet parts
All tanks consist of almost the same elements. They differ only in the mechanism of water discharge. It can be represented by one or two buttons, as well as a lever. Important details of the tank are:
- Filling valve. It maintains water at a certain level.
- Float. It shuts off the supply valve (when there is enough water).
- Drain mechanism. It is equipped with an overflow system.
- Overflow. With its help, the maximum water level is regulated.
The descent is made either manually or by buttons. This opens a drain valve that allows water to pass through and the float lowers. The two-button tank has a more complex structure. However, it saves water due to partial drainage. Also today there are toilets with a lower connection of communications. They are used when side connection is not possible.
Tank malfunctions
Everyone with a toilet flush runs into various related problems. Most often, among them are the following:
- The drain button malfunctions.
- Leaking tank or bowl.
- Water filling too noisy.
- Its continuous flow from the water supply.
- Constant flow from the tank to the bowl or to the floor.
- Water supply only after several button presses.
All these malfunctions are quite easily fixed. Therefore, the most important task is to establish the cause of the problem.
Main reasons
To understand why the toilet bowl flows, you need to open its lid and carefully inspect the inside. Most often, water is drained through the overflow hole, which is associated with improper operation of the float valve. During operation, the rubber gasket hardens and cannot close the hole tightly. Also, cracks sometimes form in the valve body. This is characteristic of plastic parts. If in normal condition the gasket is not pressed to the intended place, then this may be due to unevenness of the lever, cracks in the float, destruction of the stud that holds the lever on the valve. Also, a problem will appear when the hole in which the pin is located is deformed.
Drain problems
If, after pressing the drain button, the toilet bowl flows, it is necessary to check the drain design. This usually indicates a shut-off valve problem . She is solved simply. You need to hold onto it with your hand and press a little. Most likely, it does not fit snugly. It is important to replace the old gasket with a new one.
When the drain button is shifted, a gap forms between the valve and the hole, resulting in a leak. Need to fix the design. You must return the button to the correct position and tighten the fasteners that hold the tank. The toilet tank flows when the external nut holding the bottom is loose. In this case, the tightness is violated. This is eliminated by replacing the gasket or nut. For minor violations, you can use ordinary sealant.
Leakage overflow
Before fixing the problem, first check the valve and float. Most likely, there was a shift or skew of the lever. The cause may be the presence of liquid in the float. In this case, you need:
- Remove the float and drain the water from it.
- Dry it and seal all cracks with epoxy glue.
- Put the float back.
When the toilet bowl flows due to the float valve, the following manipulations must be performed:
- Empty the tank.
- Detach the shaped element from the water supply.
- Remove the lever and retaining nuts.
- Remove valve.
- Install a new part and secure it.
- Turn on the water supply and check the quality of the drain.
If there are problems with the siphon membrane, then it will have to be updated:
- Drain all the water. Tie the float lever to any fixed part (strap, extra board).
- Remove the nut holding the reservoir and flush pipe.
- Loosen the nut at the bottom of the tank. Disconnect the siphon and pull it out.
- Install a new membrane and put all elements back in place.
Leaks between the tank and the toilet
It happens that the tank does not overflow, and water flows from the tank into the toilet. Usually the problem is with the connecting bolt. It is made of steel, so it rusts and leaks over time. It is necessary to carefully examine this area and, if necessary, replace the fasteners.
The work is performed as follows:
- Turn off the water and empty the tank.
- Disconnect the water pipe.
- Unscrew the bolts. If they rust, they are cut down with a hacksaw.
- Move the tank and pull the shelf from the cuff.
- Drain the remaining water and remove all rust.
- Change gaskets and bolts.
- Set all elements back.
Flowing from the tank to the floor
Over time, the gasket between the bowl and the tank may shift. Then it will have to be tightened with clamps (duct tape, plumbing tape). It is necessary to untwist the fasteners and evaluate the integrity of the rubber parts. In the presence of damage (cracking, hardening) they will have to be changed. Work pads are dried. They are covered with sealant and installed in place.
To repair the toilet, it is worth choosing gaskets made of rubber, silicone, polyurethane. Flexible and elastic products are considered better. They will do a great job of sealing. They should not be inflated and cracked. In addition, they should easily crumple in the hands. It is possible that no way to fix the problem will work. Then you have to replace the plumbing fixture.
Features of repairing toilets with different flushing systems
In modern tanks, water can flow in different ways. Therefore, the repair of such toilets is slightly different. They understand quite simply. But the push-button system requires a careful attitude. Before disassembling a one-button toilet, it is necessary to shut off the water, drain its residues, unscrew the plastic nut and remove the cover. Subsequent actions depend on the type of breakdown. If a toilet bowl tank with a button flows, you need to draw a little water into it, inspect the float and correct it if necessary.
Single-button design issues:
- Water is not washed off at the press of a button. This may be due to a break in the mechanism between it and the drain valve. This part is usually replaced with copper wire or a new valve is installed.
- Flowing over the overflow. The height of the float and overflow is adjustable. To do this, unscrew the nut and change the level of the part.
- Constant flow into the bowl. Most likely, the gasket has become unusable. Therefore, you have to change the entire valve. It is necessary to unscrew the nut at the bottom of the tank, remove it and install a new element.
Repair of a two-button toilet is practically no different from its one-button counterpart. If the water does not drain, then the integrity of the elements is checked (straightened or replaced with copper wire). Incorrect position of the drain valve can lead to leaks. In this case, the height of the float or overflow changes.
Tanks with a bottom water connection are equipped with a special diaphragm valve, problems with which can occur due to weak water pressure. If it is constantly supplied under low pressure, you will have to replace the membrane with a stem element. Quite often, the toilet bowl flows in the area of the inlet valve. He is constantly in the water. Therefore, insufficient tightness leads to breakdowns. Repairing the system with the lower connection is carried out in stages. First, they shut off water, remove the lid. Then they fix the problem according to the above algorithms.
Prevention
In order for the toilet to serve as long as possible without breakdowns, it is necessary to periodically carry out preventive measures. The bowl and the tank need to be thoroughly cleaned (at least weekly). You will have to remove debris and plaque from the tank. The condition of the fittings and all fittings should also be monitored. The toilet bowls are “afraid” of mechanical damage and sudden temperature changes. If you keep this in mind, you can extend the life of the entire system. If leaks do occur, then simple breakdowns are eliminated first, and only then serious tasks are solved. When the toilet flush tank flows, you can fix it yourself. A fairly simple design is repaired without any tool. Thus, you will save on the call of a specialist and enjoy the successful repair.
