Repair the toilet flush tank with a button

Plumbing equipment is subject to intense operating loads and often fails. When the toilet bowl is constantly flowing, it causes great losses due to excessive use of water. Calling the masters due to the failure of the device is impractical, since the repair mostly consists in setting up the tank mechanism. But in order to understand how to fix the toilet, you first need to know how it works. We will figure out how to independently repair the toilet flush tank with a button.

Toilet device

The composition of the toilet includes the following elements:

1. Toilet bowl connected to the sewer pipe with a sealed cuff.
2. A drain tank with fittings to ensure it is filled with water and drained.

A water supply hose is connected to the tank. Depending on the design, it is connected to the side or bottom. The bowl and tank are usually connected to each other using bolts and seals.

Hardware accessories:

• trigger from draft with drain button;
• a locking device (inlet valve) connected to the float;
• rubber gaskets.

The principle of operation of the toilet with a button

The toilet bowl with a button is a water lock, filled with a portion of water, which is fed into the bowl when the shutter is opened. Flush control is performed by the button that you need to click on. At the same time, the valve opens, and water flows under its own weight down, washing the bowl. After the tank is released, the shut-off valve at the inlet opens, the tank is filled with the next portion to a certain level, controlled by a float. Access to the mechanism is provided by opening the top cover of the tank.

Repair Preparation

Before fixing the toilet flush tank, it must be opened. It has access only from above, if you remove the cover. In many versions, it is attached using a ring around the button. This ring must be pressed and turned counterclockwise. After prolonged use, the ring may not turn. Then a few drops of oil are applied to the attachment point. After the ring is turned, it is unscrewed, and then the button is released from the plastic clothespins and the cover is removed.

Models are equipped with one button or two. In the second case, one of them is designed for small flushing, and the other for large. To dismantle the cover, press one button and through the technological groove both are removed in turn. After they unscrew the fastening screw and remove the cover.

DIY repair methods for the tank mechanism

Through the upper hole in the tank, the entire mechanism of the drain valve is visible. It may have the following malfunctions:

1. The tank is constantly flowing.
2. No inlet water pressure.
3. Uncontrolled drain mechanism.

The causes of these malfunctions can be different, and the way in which the repair of the toilet bowl will be performed depends on them.

• Cork (bulb) does not fit snugly into the drain hole. To avoid this, you should purchase high quality plumbing. The possibility of repair can be checked by pressing the stem with a little effort. If at the same time water does not flow, the plug can be slightly weighted with an additional load or the stem can be leveled. It is also necessary to periodically clean the seal from rust and salts, due to which the tightness is broken, and the liquid constantly flows into the bowl.
• The regulator does not block the water supply. At the same time, the tank will never overflow due to the presence of an overflow pipe. The serviceability of each element of the device is checked: float, intake valve, mounts, rods. A failed part is replaced or the float mount is simply pulled up.
• Leaking from the tank to the room. It may have a crack or gasket leakage. Particular attention should be paid to the quality of the connection of the current tank with the bowl. It needs to be tightened, and if this does not help, the rubber gasket changes. Another cause of leakage may be the wear of the cuff in the articulation of the drain of the bowl with the sewer pipe. The seal is changed to a new one, having cleaned the connection of impurities and treating the surface with sealant.
• Weak head through the inlet valve. This usually happens if it is clogged. This can be prevented by cleaning or installing a filter in front of it.

Intake valve replacement

Before repairing the toilet, turn off the water tap. It connects to the piping from the riser. After unscrewing the flexible hose from the inlet mechanism. It can be easily removed by loosening the mount. Instead, a new or refurbished one is installed. Assemble in the reverse order. Plastic thread does not require sealing, and fluoroplastic tape is wound onto brass.

Drain Valve Replacement

The main reason is the wear of the o-ring under the valve. To replace it, you need to remove the accessories and install a new gasket. After assembly in the reverse order.

The water release button should always be used carefully and pressed on it without abrupt effort.

Adjusting the water level in the tank

The water level is easily adjustable with your own hands. To do this, the float is installed in a certain position.

The optimal level is considered when the water supply to the tank has stopped, and a few centimeters remain to its upper edge.

The method of adjustment depends on the design of the valve. The simplest is bending a metal bar. If the float moves along a horizontal guide made of plastic, it is fixed with the help of fasteners in a certain position. In a vertical layout, it is moved with an adjusting screw.

When choosing the filling level, do not forget about the overflow pipe. Its upper edge should be a couple of centimeters above the water level in a filled container. If it is located lower, water will continuously flow through the overflow into the bowl.

Tank troubleshooting

The tank may leak water due to a crack in it. The same goes for the bowl. In this case, the question of how to repair the drain tank or bowl is not worth it: the entire toilet is usually changed. A small crack in the upper parts of ceramic products can be repaired. So that it does not spread further, and the leakage of water does not increase, it is drilled at the ends and treated along the entire length with sandpaper. The work is done neatly.

If the crack went further during operation, the toilet should be replaced.

The surface is degreased, and the gap is filled with epoxy. After hardening, the seam is ground.

Features of repairing products with a lower water supply

Not so long ago, tanks with a lower water supply began to be used, which makes them more compact due to the absence of protruding tubes. Typical malfunctions and repair features of the toilet flush tank with a button with a lower water supply:

1. Weak pressure of water. For normal operation of the diaphragm valve, a water pressure of 0.05 MPa is required. Otherwise, water will flow into the tank constantly. The increase in pressure is created by cleaning the intake valve and filter.
2. Installation errors. Outlet fittings must not come into contact with the walls of the tank.

Repair of the built-in tank (with installation)

It is more difficult to get to the mechanism of the tank installed behind the false wall. First of all, you should purchase a device with high reliability, which rarely needs repair. In the wall there should be revision hatches through which you can get to the tank and replace the gaskets if the tightness is broken. Do not repair drain valves with your own hands due to the complexity of the design.

A coarse filter is installed in front of the hidden tank, trapping solid particles, due to which in most cases there is a leak.

How to choose plumbing?

When choosing a toilet, attention is drawn to the following.

• Way of fastening: monoblocks, compact and separate toilet bowls. The choice is made taking into account the size of the room, the design and the complexity of servicing the tank.
• Hardware. Most parts with low strength and reliability are made of plastic.
• Positive feedback, well-known manufacturer, warranty and certificate.

Conclusion

The durability of the drain tank is ensured by the use of non-corrosive and durable materials. The mechanism of the tank is simple and can be adjusted and repaired by yourself. You should purchase toilet bowls of common designs so that you can easily find a new part.
