How Does A Sump Pump Work Automatically?

Dec. 26, 2022

As we know, the submersible pumps are operated automatically in most working conditions. This is due to the float switch attached to the pump which controls pump start and stop at certain levels and avoid unnecessary dry running. 

Question: how does the float switch work? 

The float switch controls pump by the water level change. When the water is lower to half of the pump, it will cut off the power and stops work. When the water rises to submerge the pump again, it controls the pump running again.

Note: A pump without float switch will only be stopped by manually cutting off the power.
