Review: Easy to install, works like a charm! - I recently had to replace a 20 year old sump pump and I initially made the mistake of not replacing the also 20 year old check valve. I went ahead and ordered this relatively inexpensive part. Installation was super easy. No need to worry about screwing this on a threaded PVC piece, I just slipped the rubber ends on and tightened the metal bands using a flathead and it was nice and snug. Once I turned on the new sump pump, it worked like a charm and super seamless! No leaks and it was really quiet too! I love that I can also visibly see the little stopper that’s inside. Save yourself the labor costs getting a plumber to install, you can do it yourself with YouTube and some good ol’ fashioned manual labor.
Review: Best thing since sliced bread! - I wish I had known about this years ago. No more water hammer! This thing is whisper quiet and takes stress off the pump.

## Features

- QUIET OPERATION: Our sump pump check valve has a unique spring-loaded flapper that helps eliminate the water hammer noise that standard check valves produce. The water hammer noise occurs when the discharged water slams the check valve flapper down. This silent check valve can bring a quiet operation to your sump pump.
- CLEAR VALVE BODY: This check valve will provide visibility to water movement. With the valve's clear body, it's easy to visually confirm that pumped contents are moving, the pipes are not clogged, and the pump in the basin is fully operational.
- INCLUSIONS: Our silent sump pump check valve comes with stainless steel clamps and Buna-N rubber couplings for quick installation. The clamps and couplings fit a 1-1/2" Schedule 40 pipe. Fits within a 5-1/8" gap.
- KEEP WATER OUT: This check valve is designed to keep pumped water within the discharge pipe from falling back into the sump basin. A fully functional sump pump check valve can increase pump life expectancy by preventing water from being pumped twice.
- ABOUT US: PumpSpy provides sump pump systems that help eliminate the unknowns of a sump outage and prevents costly damage. We also offer Smart Sump Pump Systems that automatically track incoming data and check that a sump pump is working properly.
