Bottom valve for sink: types, mixer, device and choice

Bottom valves, although they appeared relatively recently, are already in high demand in sanitary ware shops. This product has spread all over the world, including CIS countries from Great Britain. The cost of utilities there is quite high, so the inventive English invented a simple device that holds water in the washbasin. Another reason for using bottom valves is the absence of a mixer. To get water in the sink of the necessary temperature, it is closed by a plug and mixed with hot and cold water.

Adjust the state of the bottom valve using a special button or lever located on the valve. This is very convenient, because you do not need to raise and lower the plug yourself.

In our country many sets of mixers come with such valves. A stylish metal valve is much better in the sink than a simple rubber stopper, which is not always hygienic to use.

The use of the bottom valve has many advantages, the main ones of which are:

1. Reducing water costs.
2. Ease of operation.
3. Attractive design.
4. Durable installation in the drain hole.
5. Prevents odors from entering the drain pipe.
6. Easy to clean.

Bottom valves are divided into the following basic types:

1. Mechanical. The Click-Clack system is based on the operation of the spring, under which the valve opens or closes. It is enough only one push on the lid of the product.
2. Automatic. The valve is adjusted using a small lever. The automatic system consists of small rods made of metal, the working part of which is located directly under the sink. Man acts on the lever, located in the body of the mixer.

Today you can buy a variety of valves, depending on the design and color. It can be modern, antique or stylized bronze, with a smooth or chrome surface.

These valves are the most common models. A special lever is provided for the control, which can be installed over, on the side or on top of the mixer. It comes complete with the entire kit, it is an actual inconspicuous, but very useful detail. The lever opens or closes the drain.

Less common Push Open valves. Their main disadvantage is that to open the drain hole, it is necessary to manually act on the valve, that is, to wet the hand. But such a valve is mounted quite quickly and is much easier to maintain. It is also used for baths, bidets.

The bottom valve device depends on its type. So, automatic valves have such a device:

1. .
2. Lever opening and closing the drain hole.
3. A spoke that connects the lever to the valve.
4. Threaded connection, thanks to which a drain pipe can be connected to the valve.

A mechanical valve is a single device operating on the basis of a highly compressed spring.

The installation of the bottom valve takes place immediately after the installation of the mixer, with which it is supplied. For proper installation it is necessary to follow the following steps:

1. The valve is inserted into the drain hole.
2. Special knitting needles on the valve cross each other.
3. A spoke is connected to the lever and the eyelet by means of which the closing and opening of the plug is effected.

It is necessary to pay attention to the design of the drain, because if there is overflow, a special design valve is bought. Then a siphon is connected to the valve, through which water is drained. Water is turned on, all connections are tight. If there are no leaks, then it is possible to diagnose the operation of the bottom valve. If it closes and water does not leak and then opens quickly, you can assume that the installation of the device is completed successfully.

Thus, the bottom valve is a functional product that is convenient to use and saves water. You can install it yourself using the instructions.
