Valves for a drain tank with a bottom connection: photo, installation instructions

Installation of the valves of the drain tank with the bottom connection requires the connection of the underwater pipe. The armature of this type is with two types of columns for drainage: equipped with a button or rod.

The water in the device equipped with a button descendswhen you press it. The fluid is drained automatically. In the same mode, water descends and in the mechanism with the rod. Only in this case, instead of the button, a handle is used, which should be pulled up to the end, and then released.

Modern tanks assume the presence of a button,Because she has a more aesthetic look. To ensure that the button does not protrude above its surface, the hole must be at least 40 mm. This size is calculated for round mechanisms. There are devices based on an oval button with a double start of water, as well as a rocking button. There are mechanisms in the form of a rectangle.

Device design

The valves for the drain tank with the bottom connection are:

• float;
• guide;
• a glass into which the float drops when flushing the toilet bowl;
• traction, attached at one end to the float, and on the other - to the device for locking water;
• diaphragm valve.

Operating principle

The valves for the drain tank with the bottom water connection function as follows:

• When the storage tank is freed of water, the float is lowered along the guide.
• Through the thrust, a force is transmitted that causes the valve to close. It prevents the supply of liquid to the tank.

Valve adjustment

Valve for a drain tank with a bottom line,photo of which is presented in this article, is adjusted by means of usual rotation of the screw for adjustment. It determines the position of the float to thrust. In order to fill the water with the maximum, you need to turn the screw counterclockwise, and to decrease - clockwise.

In order to adjust the water level in thea storage tank, you need to move the float chamber along the rod. If the size of the lever is increased, then you can achieve an increase in the level and vice versa. For this purpose, unscrew the fixing screw (lamb), set it in the desired position and fix it. You can move the float on the plastic rod with the teeth. In designs in which the bar is made of metal, in order to change the water level, you should bend the bar in the desired direction.

Nuances of construction

The valves for the drain tank with the bottom connection have their own distinctive features.

The functionality of the membrane valve directlydepends on the quality of the water that enters the tank. It must be filtered. Otherwise, you will encounter a problem such as clogging the parts. This will stop the water supply to the tank.

Installing the drain valve with the bottomalthough it has its own advantage, since it makes the design invisible, but such a device is difficult to repair. When fixing, you may encounter inconvenience due to its location.

Common cause of breakage of all locking mechanismslies in the fact that the integrity of the float is violated, which causes its flooding. Water constantly enters the tank and is washed into the toilet through the overflow pipe.

At the connection point of the device leakage is possible, which is caused by insufficient fixation of the nut or disruption of the functionality of the gasket from the rubber.

How is the valve replaced?

The old valve of the drain tank with the bottom connection before installing a new one must be dismantled. Often, the replacement of the device is not required, and it is sufficient to replace the discharge column or the valve. If you change the column, you will need to dismantle the tank, and when installing a new valve - no.

Before you start, close the water at the inlet to the tank or turn off the riser. All the water in the tank should be lowered. Dismantling with push-button and rod construction will be considered.

1. The button is removed by loosening againsthour hand. It happens that it is attached to the lid of the tank. In this case, the lid is removed with it. In the rod-type device, the decorative knob should be turned off and the cover removed, which closes the hole in the tank through which the rod passes.
2. In the center of the valve there is a column for draining. The jellied valve is located on the side. If the length of the hose allows you to remove the tank and put it directly on the toilet, then go to the next step.
3. A collapsible column consists of twoparts. For simplicity of repair work it is necessary to dismantle the top part. It must be turned 90 °. When you detach it, you will hear a click. Inside, the lower part of the column remains. On the sides are visible hats from bolts, through which the tank is fixed on the toilet.
4. Unscrew the fixing nuts under the cistern. This process can be done both with tools and manually. After draining in the tank, there is a little water, which will drain out when the nuts are loosened. It is advisable to lay a rag.
5. Lift the tank and put it on the toilet.
6. In the event that the flood valves are to be replaced, the flexible hoses should be wrapped and unscrewed by hand. You can use the keys.
7. The nut securing the column is loosened, as well as the valve nut.
8. From the tank all the parts are taken out.

Now it remains to replace the old elements with new ones and assemble the structure in the reverse order.

What tools will you need?

Regardless of which type of valve is installed in the drain tank, it will be necessary to dismantle it:

• spanners;
• ruler;
• two adjustable wrench.

Troubleshooting the most common problems

When using a locking device,It happens that the functionality of the drain tank is broken. In this case, repair work should be carried out. On how to repair the valves for the drain tank with the bottom line, the instruction is given in this article.

We will consider the most common problems, the elimination of which is possible on their own. This requires knowledge of the common valve arrangement.

Water does not enter the tank

The most common cause of this problem lies in theclogging the narrowest part of the valve. To solve the problem, empty the tank and unscrew the valve together with the lever and float. You will notice a narrow hole through which water enters the tank. It can be cleaned with a needle or a thin wire.

It is necessary to unscrew the inlet valve slightly and rinse the remains of the blockage. In the case of free water supply, the valve must be tightened and the valve with the lever and float in place must be installed.

Constant water flow

There are two reasons for this phenomenon. One of them lies in the skew of the float. In order to repair the device, you should:

1. Unscrew the lock ring at the start button and remove the cover.
2. Carefully inspect the float. If the part is under water, it is necessary to raise it. As a rule, it clings to the valve lever for draining.
3. Check if the mechanism works correctly. For this purpose, drain the water and check how much the float rises. When the required level is reached, the valve closes the flow of water.

Over time, the membrane of the sealing ring loses its elasticity. Therefore, it is advised to replace it. Choose the same model.

Trouble in the drain tank equipped with a button

When the button is pressed, the water enters the toilet bowl. The float goes to the bottom. The hole is closed by the valve. When the water enters the tank, the float begins to rise. Having reached the required height, it helps to close the nozzle opening.

If the water is collected in the tank, the cause should be sought:

1. In the wrong position of the float. To do this, remove the cover or repair the problem.
2. Possible loose fit of the pear to the drainpipe. In order to conduct a test, you need to press the pear on top. If the water does not drain into the toilet, the cause is found. To eliminate this breakdown, you should weight the pear with any load.
3. The pear of rubber fell into disrepair. It does not seal the drain pipe and must be replaced. To this end, you should fix the float above, remove the old pear and buy a similar size of soft rubber.

To remove the cover equipped with a button, unscrew the locking ring around the button. Do not press too hard, as you can break it.

Features of the design from different manufacturers

What is necessary to know the features of the mechanismswith the lower type of podvodki from different manufacturers? Without this, it is very difficult to fix a problem that can characterize a particular device. Consider the models that are most popular.

Fittings for a drain tank with a bottom connection fromfirm Cersanit differs simple design. The device is very reliable. It is made according to the classical scheme: the locking mechanism is fixed by means of a pear.

The most common problems in this device are:

1. Improper adjustment of the valve responsible for the supply of water. As a result, the liquid is quickly consumed.
2. Too much pear. Sometimes the device clings to rough thermal walls, because of which water overflows.

In general, the products of this company are distinguished by quality and reliability.

Valves for a drain tank with a bottom connection"Keramin" has its own distinctive feature. It is in the position of the float. It, like in devices manufactured abroad, is mounted not on the horizontal, but on the vertical axis of the valve. This design is reliable, and the float does not jam.

One of the most qualitative are the models frommanufacturer Porta. Most models of tanks of this company are made with one button. The pear is regulated very simply. Thanks to this, any level of water filling can be ensured. This valve is designed for a tank with a small volume.

The same features of the design of the valve for the toilet tank with a lower supply of water from Sanita and Colombo. At first glance, their device seems too simple. But to carry out repairs, you need to know the principles of recovery.

The valves for the drain tank with the bottom connection Iddis are made of high quality ABS plastic.

The material is different:

• strength;
• high resistance to alkalis and acids;
• resistance to wear;
• ecological safety.

Uniform regulation of the amount of water supply contributes to the economical use of the liquid.

Summing up

It can be said with certainty that, if observedall the rules for the installation and use of the water filter, the valves for the drain tank with the bottom connection are reliable and comfortable. It does not make noise when the tank is filled with water. But it should be noted that devices with a top connection are much cheaper and easier to repair.
