Bottom valve for the sink - the russian economy in the
A distinctive feature of Europeans is manic saving on everything, including on water. This fact, coupled with the specificity of the water supply - the lack of mixers, was the reason for the emergence of a bottom valve, of which England became the mother. This supplement for the sink is still in the category of new products for domestic consumers and its testing on the Russian open spaces is still ongoing.

Sink and mentality
Having heard the words “bottom valve” for the first time, not every person will be able to immediately understand what it is. And this invention of the British, who did not guess to invent a mixer or who considered this convenience as extremely unaffordable luxury. Although it is probably convenient to wash or wash your hair in a sink pool.
It is difficult for a Slav to understand this, for every wash of his face he makes with renewed water. In most cases, a modified shell in our country is a fashion or a simple human curiosity. And since the valve is included in the kit of many models of mixers, then why not install it, especially since the sparkling circle looks prettier than the drain hole.

It is fair to admit that in some cases the bottom valve can be very convenient - wash the little things, kids splash, handle the steam before the cosmetic procedure or cool head after the holiday to cool. But in the kitchen sink and bathroom water valve will undoubtedly be a more useful and economical device.
The part itself does not have an exceptional sense, and therefore does not require a fateful change in the installation of the mixer-sink-drain chain for the sink with a bottom valve. The device is installed / removed in minutes, which makes it extremely easy to clean.
Note! Over time, valve wear can lead to a leak, so it is advisable to have a sink with overflow in order to avoid neighbors flooding.
Types of bottom locking devices
Valves are available in 2 types:
- mechanical (spring) - Click-Clack, which are regulated with one touch of a finger on the cover of the device;

- automatic, controlled by levers.
The lever system is a thin metal rods, the main connection of which is located under the sink. The lever with which the person will directly “work” is located in a slot in the back or side of the mixer housing.

The meaning of the use of bottom valve
Hydraulic closure suitable for any sink - angular, moidydra, pedestal.
The price of valves can vary from 900 to 4000 rubles or more and depends on several parameters:
- material (brass, bronze, ceramics);
- type of coating - chrome, color;
- type of cartridge responsible for mixing hot / cold water. Italian Newform cartridges are able to withstand a hydraulic shock up to 35 atm;
- manufacturer.
Operation of the water cap is comfortable and pleasant for several reasons:
- convenient and easy control with one finger;
- outwardly attractive appearance that has nothing to do with the former traditional traffic jams made of plastic and rubber;
- easy cleaning due to ergonomic shape;
- reliable fastening in the drain hole, which excludes the possibility of getting lost, before the plugs were attached to a fishing line or chain;
- protection from unpleasant odors from the drain - it is not enough that it can happen;
- keep your jewelry from traveling to the depths of sewer pipes;
- water saving.
Some annoyance can cause:
- spring models, opening / closing which need to lower the hand into the dirty water;
- the inconvenience of cleaning the levers under the sink;
- and a hole in the mixer, which is located behind - out of sight.

Installation of the water stop
A full siphon, equipped with an exhaust pipe, which is fed to a drain hole at the bottom of the sink, allows you to install the mixer for the washbasin in the kit with a foot valve. A semi-siphon for a sink with a bottom valve that does not have an outlet will allow the selection of a Click-Clack system valve.
Note! To avoid scratching chrome surfaces, use tools with sponges. If not, you can use cardboard, copper or brass pads.
Since the water gate is often supplied with a mixer, consideration of the installation work will include the installation of both of these nodes.
- The flexible hoses and the lever of the valve are moving away from the mixer - this is all displayed in the hole below.

- The body of the crane is mounted with a gland nut over the corresponding hole on the pedestal of the sink. Rubber pads must be placed on both sides of the mounting hole.
Note! If the supply is made of rigid tubes, they may have to bend with their own hands, which requires a certain skill. If the tubes need to be shortened, then when cutting and grinding, the chips can get inside and ruin the work of the crane - it will not turn. It will help the dismantling of the aerator and flushing the "insides" with a strong jet of water.
- Attach hoses to hot / cold water connections with rubber gasket nuts.. U-shaped bending of pipes is allowed, S-shaped is unacceptable, because it impedes the movement of water flow and increases pressure, which adversely affects the points of connection.
- Place the trap in the drain hole.
- The spokes (levers) of the device folded crosswise and secure with a special plastic cross.

- One end of the needle is connected to the lever and with the eye of the valve. Moving up and down, the lever will move the needle, which will allow the valve to move.

- Connect siphon or flute from below.
- Bring the hose to the drain pipe.
- Test the assembled system as required by the instructions.. First let the water flow in the usual way, and then try out the valve: close it, fill the sink and drain.
- If a leak is detected, tighten the threaded connections.. It is possible that in these places will need sealing tape.
- If all joints are dry, you can congratulate yourself.
Summarizing
At first glance, useless devices for bathrooms, showers or sinks may actually be indispensable. Providing comfort, they become both design elements and create a relaxed atmosphere. And the practical application of such innovations, such as, for example, the bottom valve, will expand as we get used to the European “little thing”. Because if in Europe people are economical, then in Russia they are creative.
Any theory should be supported by the case and the video in this article can be for you a practical tool for installing a bottom valve.
