## Description

PumpSpy's Silent Sump or Sewage Pump Check Valve brings quiet operation and visibility to your pump system. This check valve is designed to allow maximum flow from your pump. The clear valve body shows if the contents are moving and if the pump works as designed. The spring-loaded flapper keeps the operation quiet, with no jarring water hammer noises. Our sump or sewage pump check valves are made with easy installation in mind and come with stainless steel clamps and Buna-N couplings that fit 2″ pipe. This sump pump check valve can quietly prevent water from being pumped twice and extend the life of a pump. Product Specs: Model: CV-200, 2-inch check valve, spring-loaded flapper Dimensions: ‎10 x 4 x 4 inches; Weight: ‎1 pound.

## 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 2" Schedule 40 pipe. Fits within a 7-1/4" gap.
- KEEP WATER OUT: This check valve is designed to keep pumped contents within the discharge pipe from falling back into the sump basin. A fully functional check valve can increase pump life expectancy by preventing contents from being pumped twice.
- ABOUT US: PumpSpy provides sump pump systems that help eliminate the unknowns of a sump outage and prevent costly damage. We also offer Smart Sump Pump Systems that automatically track incoming data and check that a sump pump is working properly.

## Customer Reviews

### ⭐⭐⭐⭐⭐ This should be considered a mandatory upgrade part for any sewage sump.
*by J***N on April 28, 2025*

Once you get past the horror of replacing the old one with this, which thank the heavens is a quick task with the band clamps (have a large bucket in place, and pray you don't have six feet of "effluence" trapped above it when you undo that last clamp), and have finished decontaminating everything in sight in case it splashed out, you can enjoy the spectacle of safely watching your poo flow by every time the pump kicks on. It's like a tiny little pooquarium most of the time, at least in vertical installations, as whatever poo-water is still in the vertical pipe above the valve when the pump stops, stays in the vertical pipe above the valve. It always did, just now you can see it. Which is helpful for seeing at a glance if the pump is actually moving anything when it runs, and what exactly, in disgusting detail, is being moved. If your old valve was a cheap Home Depot special like mine was, and would always thump loudly like a demon pounding to get out of the poo-well, startling the bejeezus out of you in the middle of the night every time the pump stopped becuase a six foot column of poo water slammed the valve close, these geniuses somehow also made your new pooquarium virtually silent too. Great upgrade to a rather horrifying part of your plumbing system, giving you a way to easily monitor and partly diagnose what's going on with it, when necessary, without having to traumitize yourself by actually unsealing the lid of that cursed pit, until you know you have to. Or if you've decided to traumatize your plumber instead, you'll be able to give him a little more information to work with beforehand.

### ⭐⭐⭐⭐⭐ Easy to put in and very quiet
*by C***E on June 8, 2025*

Have tried many check valves and this one is the best hands down. Easy to install, silent, and can see water in.

### ⭐⭐⭐⭐⭐ Stopped the air hammer.
*by A***R on May 18, 2025*
