Best Sump Pump Float Switch FAQs

How does a sump pump float switch work?

A sump pump float switch is an essential component of a sump pump system. It works by activating the pump when the water level in the sump pit rises above a certain point. The float switch is attached to a rod that is connected to the pump's motor. When the water level rises, the float switch rises with it, triggering the rod to activate the motor and pump the water out of the sump pit.
