Check Valves

Check valves in the valves and flow control category serve the same anti-backflow function as plumbing check valves but are stocked here for easy access during valve system repairs. These one-directional flow components are particularly important in ozone and chemical lines where backflow could contaminate equipment. Spa Guy Parts carries check valves in common hot tub sizes with both barb and slip connection options. Protect your spa plumbing from harmful backflow—free shipping over $75.
