Check Valves

Check valves allow water to flow in only one direction through your spa's plumbing, preventing backflow that can cause equipment damage or contaminate the water system. They are commonly used in ozone injection lines and chemical feeder connections. A failed check valve may allow chemical or ozone backflow into the pump or heater. Spa Guy Parts carries replacement check valves in common spa plumbing sizes. Protect your spa's plumbing system integrity—free shipping on orders over $75.
