Bottom valves

Valves

— the bottom valve is a spring stopper (auto stopper), which allows you to block / open the entrance to the sewer with a slight movement of the hand. This type of shut-off valve is designed for installation in kitchen sinks, washbasins, deep shower trays, jacuzzis, hot tubs, etc. The original purpose of the foot valve is to save water. That is, instead of using running water, which in a half-clean state goes into the sewer drain, it is better to draw it into the plumbing bowl, which will allow you to reuse the water. There are two most common types of bottom valves: lever (which is raised/lowered with a lever) and push ("click-clack"), which must be pressed with a finger/hand.
