One of the most important considerations when installing irrigation systems is preventing unsanitary water from reversing back into the source. Manual check valves offer basic insurance against backflow by closing off when they sense water flow switching directions. While not approved in some jurisdictions for drinking water protection, they are excellent for shielding irrigation water from getting into pools, birdbaths and other fixtures. They also can be installed in-line for above-ground runs, which uses less pipe than an anti-siphon valve.

Professionals can shop at SiteOne Landscape Supply for hundreds of manual backwater valve solutions from NDS, Spears, American Granby and other brands. We offer all types of check valves, including swing check valves for reduced turbulence, stop check valves that double as a shut-off valve and double-tap check valves for attaching a pressure gauge. You can get a lightweight PVC check valve, heavy-duty bronze valve, rustproof aluminum valve and many others. Contact or visit your local SiteOne branch for answers to any check valve irrigation challenge.
