Overview

The Letzgo Sump Bobber is a float switch that monitors the water level in a sump pump well. Clamp it to the return pipe slightly above the point where the pump normally starts.

Connect it to a warning device or alarm system and it signals when the water rises past the pump. The float is reversible. Fit it one way for a normally closed circuit, the other way for normally open: remove the C clip, reverse the float and refit the clip. The sealed reed switch keeps the circuit isolated if the pump wiring breaks down.

Good for: Sump pits where a tethered float keeps sticking.
