Common reasons why condensate pump keep running continuously – Float switchThe sump pump float switch, an instrument of diminutive proportions, is a device of utmost significance that regulates the functioning of your sump pump. Embedded within the sump pit, it comprises a buoyant ball or cylinder that levitates atop the water level. In an event where the water level in the sump pit escalates, the float switch gradually ascends with it. Upon reaching a predetermined altitude, the float switch triggers the sump pump to commence its operation and begin purging the water from the pit.

The float switch comes in two primary categories: vertical and tethered. The vertical float switch is an optimal choice for smaller sump pits as they require less space for operation. However, if one possesses a larger sump pit, then tethered float switches would be a more fitting alternative. These float switches provide enhanced flexibility concerning water level adjustments, thereby offering greater accuracy in regulating the sump pump’s activity.
