PumpSpy 1-1/2 in. PVC Freeze Drain

The Sump Pump Discharge Freeze Protection Device allows water to escape through its perforations when a sump pump discharge line gets clogged. By giving the water a secondary escape route, the Freeze Protection Device will prevent the pump from overworking and the basement from flooding. Fits 4 in. and 1-1/2 in. standard schedule 40 PVC piping.
