A fully functional sump pump check valve can increase pump life expectancy by preventing water from being pumped twice. Keep water out: this check valve is designed to keep pumped water within the discharge pipe from falling back into the sump basin.

We also offer smart sump Pump Systems that automatically track incoming data and check that a sump pump is working properly.

About us: pumpspy provides sump pump systems that help eliminate the unknowns of a sump outage and prevents costly damage.
