Hayward FILTER HEAD W/VENT VALUE

The Hayward Filter Head with Vent Valve is a critical structural component designed for use with Star-Clear series cartridge filters, serving as the pressurized lid that seals the filtration tank. Manufactured from a high-strength, glass-reinforced thermoplastic, this assembly is engineered to withstand the rigorous hydraulic pressures of a pool's circulation system while resisting UV damage and chemical degradation over time. The integrated manual air relief vent valve is a key safety and functional feature, allowing the operator to safely bleed trapped air from the system during pump startup and to depressurize the tank before opening it for maintenance. The head also typically includes a threaded port for a pressure gauge, enabling real-time monitoring of filter performance and debris accumulation. For shipping and logistical purposes, the estimated weight of the Hayward Filter Head with Vent Valve is approximately 4.5 pounds in its protective packaging, while the actual weight of the molded head and valve assembly is roughly 3.6 pounds.
