The pumps consist of a cylinder, inside which runs up and down tightly adjacent to the walls of the piston. At the bottom of the cylinder and in the pistons are installed valves that come off only upwards. When the piston moves upwards, the water enters the tube under the influence of atmospheric pressure, lifts the lower valve and moves behind the piston. When the piston moves down, the water under the piston presses on the lower valve and it closes. Simultaneously, under the pressure of the water, a valve inside the piston opens and the water passes into the space above the piston. In the subsequent movement of the piston up with it rises and the water above it, which is poured into the drainpipe.
