Drain it Dry: There's more to the humble sump pump than you'd expect

Zoeflen Cycling - how many times the motor runs in the pump. If it's cycling with a high frequency in the pump, that's not a good sign. If the pump comes on but won't shut off, the float switch is out of adjustment If the pump is running but not pumping, the pump is probabh/ air locked. Make sure your 3/16" vent hole has been drilled and it is not clogged If it has not been drilled, disconnect the pump from your power source and drill the hole.
