Review: Working sump pump check valve - Installed today on a 1hp sump pump, and the check valve appears to be working well. I don’t see water returning to the pit from the discharge pipe. I had tested the unit out of the box (pre-installation) and noticed there was a small trickle from the flap. I believe this trickle is only due to not having enough water weight as compared to a full discharge tube of water pressing down on the flap. It’s a nice, quiet check valve, with a pre-drilled weap hole, easy to thread onto the sump pump, etc. Far better than the Wayne brand that is similar and similarly priced ~$20. Nice compact design that fits in narrow sump pit or a multi pump pit.
Review: No gluing PVC makes install a breeze - Paired this with a Zoeller 1/2 horse pump. Works perfect and is quiet. Makes installation a breeze. No glue needed.

### ⭐⭐⭐⭐⭐ Working sump pump check valve

### ⭐⭐⭐⭐⭐ No gluing PVC makes install a breeze
*by D***S on November 30, 2025*

Paired this with a Zoeller 1/2 horse pump. Works perfect and is quiet. Makes installation a breeze. No glue needed.

### ⭐⭐⭐⭐⭐ If you're looking for a check valve that simply works, look no further.
*by D***R on August 12, 2024*

By installation has a little over 9ft. rise and so far (three months into use with a number of large storms driving much sump pump activity) this valve has simply been great. Not only has the check valve kept the pipe filled above the valve during active periods. it's held water over day. There's no audible sound from the valve. Highly recommend.
