1. Exceptional Backflow Protection: Ensure the longevity of your system by preventing pumped water from flowing back into the sump basin. This eliminates the risk of inefficient double pumping, extends the lifespan of the sump pump, and guarantees a more durable and reliable plumbing system. 2. Quiet Operation Strategy: Enjoy the peaceful sound of silence thanks to the unique springloaded flapper design of our sump pump check valve. It specifically targets and eliminates the water hammer noises produced by most check valves, making it for noisesensitive environments like bedrooms or living spaces. 3. Smart Visibility: The transparent body of this check valve is more than just an elegant design choice. It provides a clear view of water movement, giving you confidence that water flows smoothly, pipes remain obstruction, and the pump operates at peak efficiency. 4. Precise and Hassle Installation: This check valve is designed to fit with a 11/2' Schedule 40 pipe, seamlessly integrating into your existing plumbing setup. Its compact design requires only a 51/8' clearance, ensuring a secure fit with minimal installation effort.
