Hayward CHECK VALVE

The Hayward Check Valve is a critical plumbing component designed to ensure unidirectional water flow within a pool or spa circulation system, effectively preventing the hazardous backflow of water when the pump is deactivated. Manufactured from high-impact, UV-stabilized CPVC or clear acrylic, this valve is engineered to withstand high hydraulic pressures and the corrosive effects of concentrated pool chemicals. Its primary mechanical function is to protect sensitive equipment, such as chlorinators and heaters, from the reverse flow of highly sanitized water that can cause internal corrosion or scaling. The internal mechanism typically features a spring-loaded or swing-style flapper with a specialized elastomeric seal that creates a watertight closure even under low-pressure conditions. Designed for minimal flow restriction, the valve helps maintain system efficiency while providing a clear housing in many models for easy visual inspection of the internal assembly and debris accumulation. For shipping and logistical purposes, the estimated weight of the Hayward Check Valve is approximately 1.4 pounds in its retail protective packaging, while the actual dry weight of the individual valve unit is roughly 1.1 pounds.
