The bottom valve appeared on the Russian plumbing market only two decades ago. Faucets equipped with this device were invented in Europe. And now, a large assortment of them is produced by domestic manufacturers. The device gained popularity due to its purpose. This is a cap for plumbing, which reduces water consumption.
Description
The bottom valve closes the drain when it is necessary to draw water, wash clothes or wash dishes, rather than pouring dozens of liters of liquid in vain. They are equipped with faucets. In fact, this is an improved model of an ordinary plastic stopper plug, only more reliable. It is attached to the bottom of the sink. Varieties of bottom valves:
- Mechanical. This valve is mounted in the sink. To activate it, you need to press the lid. The inner spring will open up and slide the plug covering the drain. Some manufacturers refer to this product as Click-Clack or Push Open. It works regardless of the mixer. Installed in shower trays, washbasins, bidets, siphons and bathtubs.
- An automatic basin mixer with bottom valve is supplied. It is controlled by a lever located behind the washbasin or to the side of the mixer. This is a more popular variety, as it is convenient and hygienic to use. Suitable automatic bottom valve for washbasin and bidet.
It was the equipment with the mixer that aroused the interest of local consumers, because immediately the benefit of its use became clear. And another important plus is that during installation it is not necessary to dismantle an already installed sink. Most of the structures are located under the sink, do not catch the eye and do not spoil the appearance.
The bottom valve with mixer can come with and without overflow. By external signs, the differences are almost imperceptible. But the difference in functions is visible. In the first case, after the shell is completely filled, water will not overflow. The excess will merge into the sewer. In the second case, you need to be careful not to leave the closed valve under the stream of water unattended.
Operating principle
Mechanical valves are a pressure plug with a spring. The device is easier to install than automatic. These models are represented by a diverse design and are very compact. Plus such an invention in a more attractive appearance. There are no bulky levers, but only a steel, bronze or bottom chrome valve.
The automatic equipment includes the following details:
- Stub. This is the valve that closes the drain hole.
- A pen. To actuate the mechanism, you need to turn the lever.
- Kernel. The connecting element is between the handle and the plug.
- Thread. The device is connected to the siphon by thread.
- Siphon. Options for draining the water.
Application advantages
There are several significant advantages to using a bottom valve:
- Saving. With an increase in utility tariffs, a device that saves water is very important. On average, the easiest valve today can be purchased for 500 rubles. More advanced models are available at a price of 2 thousand rubles. This is a very modest price to save the budget.
- Ease of use. To actuate the valve, simply press a finger or turn the knob. No need to make an effort. Even a child can cope.
- Convenient shape. The device is easy to clean from dirt and blockages.
- Interesting design. Smooth chrome plug looks nicer than an empty hole in the washbasin.
- Strong fastening. Screwed parts, in contrast to obsolete plugs on the chain, are much more reliable during operation.
- Odor barrier. A common occurrence is the spread of ammonia smell from sewage. Household chemicals do not always help. The problem can be solved by simply closing the hole.
The bottom valve has almost no flaws. In mechanical devices, the unpleasant moment is that you need to lower your hands in dirty water. The only way to merge it. And in the automatic, it is necessary to clean the parts included in the kit, which are located under the sink.
How to choose?
When purchasing a product, it is better not to save. Moreover, the price of the plugs "do not bite." The more expensive the valve, the better it is. The cost depends on the additional availability of overflow function, control method, material, design and manufacturer.
The device is selected according to the type of washbasin. You also need to focus on the purpose for which the product is purchased. If you plan to wash in the sink, you can install a regular valve. And for washing greasy dishes, it is better not to save money and purchase a valve complete with a mixer.
Conclusion
The bottom valve is a useful and necessary thing in the household. But if it fails, it can cause a number of troubles. Therefore, the choice is best taken responsibly and give preference to trusted brands.
