In a sump pump application, latching of the SCR allows the pump to remain activated after the liquid level is reduced below the upper probe.doi:US5216288 AJames L. GreeneUSUS5216288 1991年11月15日 1993年6月1日 The Marley Company Water level control circuit for sump pumps and the likeUS...
A simple installation provides a pump control float switch that turns on the backup pump only water in the pumping chamber reaches a level above that normally handled by the primary sump pump. This approach provides both pump backup and the ability to handle surges in building water entry loads...

According to some writers a sump pump should be connected to a GFCI circuit. But we find that wet locations sometimes keep tripping off the GFCI - a safe condition, but it means the building is likely to become flooded because the circuit powering it has shut down. Some writers and ...

Basic sump pump maintenance is usually as simple as doing these few jobs. Make sure the pump is plugged in to a working ground fault circuit interrupter (GFCI) outlet and the cord is in good shape. In damp areas, GFCI breakers may trip, effectively shutting off the sump pump. Check in ...
