Over time, the rubber plug was modified and it received the name of the bottom valve in the mixer, although the device has more to do with the siphon than the mixer, without affecting the supply of consumer tap water. But due to the fact that the valve often comes bundled with a mixer and is connected with it by a system of levers, it is customary to refer to it in relation to the mixer.

Structurally, the bottom valve is designed as a plug, driven by a lever mounted on the back of the mixer. The device is also equipped with a needle that connects the plug with a mixing lever and a threaded connection for connecting the drain pipe or the siphon. In order to close the cork, it is enough to press the lever with one finger and the water will not drain into the sewer system. This will allow rinsing the washed dishes in the sink, washing out small things or placing aquarium fish there while cleaning the aquarium.

This is especially true for sinks and kitchen sinks, in which the washing of dirty dishes and washing. Another drawback of the installation of bottom valves is the implementation of continuous monitoring of the level of fluid in the sink. The use of a locking device requires the constant presence of a person in the room, otherwise the water will reach the edge of the sink and flow.

However, the most modern models are equipped with the overflow function, and immediately open the valve when the pressure increases or the liquid rises above the critical level. Among the disadvantages is the need to lower the hand in the sink with dirty water when using spring valves. However, this deficiency can be easily corrected by choosing a lever model, which, when used, does not need to lower hands into the water.

Varieties

The modern market of plumbing represents two types of bottom valves. The first one is represented by lever automatic models consisting of a control lever, a cork and a connecting rod.

The second type of valves is represented by mechanical models of the click-click system under the general name Push Open. Structurally, such products are arranged much simpler than automatic analogs, and consist of a plug-cap, a central rod, a spring, and a clamp. Such valves, undoubtedly, are more effective than lever, but in terms of usability and hygiene, they are somewhat inferior to them. The fact is that mechanical models are autonomous devices and have no connection to the mixer. The valve is controlled by pressing the plug, for which you have to put your hands in polluted water.

For more sophisticated classic bathtubs and washbasins, valves of gold and bronze colors are used. Products can also be matte or glossy or be artificially aged.

Tips for choosing

Before you start buying a bottom valve, you need to determine for yourself a number of important criteria, the first of which will be the choice of the model design and method of controlling the plug. So, if the device is purchased for a kitchen sink, in which it is supposed to wash dirty dishes, it is better to opt for automatic lever options. If the valve is installed in the sink for a set of water for the purpose of small washing, then we can limit ourselves to a more inexpensive mechanical model. No less important criterion is the type of sink.

In addition, when buying, you should carefully read the instructions or other accompanying documentation. In it, as a rule, the maximum permissible level of temperature of the liquid, the metal of manufacture and recommendations for proper operation are indicated.
