Hayward CHECK VALVE

The Hayward Check Valve is a heavy-duty hydraulic safety component engineered to maintain unidirectional water flow and prevent the damaging effects of backflow within pool and spa plumbing systems. Constructed from a high-impact, transparent or opaque CPVC body, it features a spring-loaded or swing-style flapper mechanism that automatically seals when the pump is deactivated, protecting sensitive equipment like heaters and chlorinators from the reverse flow of concentrated chemicals or debris. Its robust design is specifically built to withstand high hydraulic pressures and the corrosive environment of salt and chlorine-treated water, while the clear-cover versions allow for easy visual inspection of the internal seal and debris accumulation without needing to disassemble the plumbing. By ensuring that the pump remains primed and that water moves only in the intended direction, this valve optimizes overall system efficiency and prevents air from entering the filtration lines. For shipping and logistical purposes, the estimated weight of a standard Hayward Check Valve is approximately 1.6 pounds in its retail packaging, while the actual weight of the valve unit itself is roughly 1.2 pounds.
