Fernco check valves allow for the unrestricted flow of water up and out through the pipes, but when the pump turns off, the water in the pipes doesn?t flow backwards back into the sump pit causing more work and wear on the sump pump.
Features:
- Installs with Fernco flexible couplings for fast and easy installation
- Full flow positive sealing flapper design
- Heavy duty for long life
- Eliminates backflow and wear on pump
- Durable thermoplastic body
