Keep water from returning to the sump pit or crawl space after the pump shuts off with a Sump Pump Check Valve. Keeping the basin or crawl space free of water and preventing backflow is vital, and a sump pump check valve allows for easy pump service without cutting any pipe. We also offer Swing Check Valves, which are compression mount and provide an easy solution to servicing the pump without cutting pipe, plus there is no messy glue to set before testing or using the pump.
