Flotec 1-1/4 in. or 1-1/2 in. Sump Pump Check Valve

The Flotec 1-1/4 in. or 1-1/2 in. Sump Pump Check Valve is engineered to keep your basement and drainage systems running efficiently. Built with a durable PVC body, this check valve prevents water in the discharge line from flowing backward into the sump basin when the pump cycles off. Its flapper-style mechanism operates with minimal unseat pressure to ensure smooth flow and dependable backflow prevention. Designed for versatile plumbing options, this valve can be connected with accordion sump discharge hoses, flexible polyethylene, rigid PVC, or galvanized pipe. The integrated anti-airlock relief hole minimizes the risk of pump air-locking, helping extend pump life and maintain reliable drainage performance.
