These devices differ among themselves in several parameters:
The main metals and alloys for the manufacture of these plumbing devices are bronze, brass, aluminum alloy with silicon (Silumin). They are chrome or nickel to give them to give an aesthetic appearance, shine and protection from rust. The faucets can also be matte.
In terms of action, the most common are two types:
ball (with one lever). The design is one handle, which, with vertical lift, turns on water and regulates its pressure, and when moving in a horizontal plane changes the water temperature.
Two -tarnital. The traditional type of mixers, in which hot and cold water is supplied separately. Have an affordable price, many design options. Previously, rubber gaskets were used as internal seals, which quickly failed and were subject to frequent replacement. Modern manufacturers set ceramic parts instead, with which the service life is significantly prolonged.
The faucets also differ in the location: washing in the kitchen, shell in the bathroom, shower mixers. For each type of plumbing, you need to choose the right mechanism so that it performs its functional tasks. For example, the length of the nose (spout) plays an important value. Too short nose at the mixer for the kitchen can be inconvenient in operation. If you plan to use one mixer for the washbasin and bath, then you should choose a device with a fairly long spout, which can be moved to the right place.
