First, it would be nice to determine which mixer is more suitable in a particular bathroom — a single -leaf, two -wagon or thermostat. A single -leaf mixer is more convenient to use and easy to install, but the water temperature will have to be adjusted all the time. The two -welfare will have to be “twisted”, but the desired degree of water will be accurate. At the same time, it is worth finding out which seal is used in the mixer, t. To. Ceramic serves longer, and rubber is indispensable with hard water. There is another type of mixer — thermostat. Externally — this is a panel with handles, one of which is responsible for the supply of water, the other for the temperature. The main plus of the thermostat is that a comfortable degree of water can be set once, which means that no burns and hypothermias are scary to the user. Moreover, if desired, such a function can be disabled.
