A normal sump pump operating cycle should last between 10 to 30 seconds, depending entirely on your sump pit basin size and groundwater inflow volume. The pump should activate when water reaches the upper float switch threshold, rapidly expel the accumulated water out through the exterior discharge pipe, and shut off automatically once the water level drops back down to the bottom of the basin. Verification: Observe a complete pumping cycle to confirm the motor turns off automatically once the pit empties.
