Simple, straightforward and low shipping rates for these check valves.



Sump Pump Check Valves


Keep water from returning to the sump pit or crawl space after the pump shuts off with a Sump Pump Check Valve. Keeping the basin or crawl space free of water and preventing backflow is vital, and a sump pump check valve allows for easy pump service without cutting any pipe. We also offer Swing Check Valves, which are compression mount and provide an easy solution to servicing the pump without cutting pipe, plus there is no messy glue to set before testing or using the pump. For other check valves, check here.

Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that PlumbingSupply.com® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.

Frequently Asked Questions

Q. "Why are spring check valves not commonly used for sump and sewage installations?"
A. Some spring check valves have a center spring and shaft that can snare particles or debris and cause the check valve to not properly close.
