Review on 🔇 Efficient & Silent 1-1/2" Sump Pump Check Valve for Noise-Free Operation by Leandro Gray

My drain pump runs a lot and it's right under my bedroom. I was always annoyed by the loud water hammer from my old check valves and couldn't find a solution. When I saw this check valve at Revain I was intrigued but skeptical. I ordered it and it came faster than promised and I installed it quickly. I was surprised! Such a simple design, but IT WORKS! The only sound I hear from the swamp now is water flowing through the pipes. If you are also annoyed by the loud rattling of the check valve, I can warmly recommend this low-noise check valve. I will be ordering a second one to have on hand as a backup.
