About This Item
The Hayward Filter Head with Check Valve and Locking Ring (CX400BA) is the OEM replacement filter head assembly, incorporating an integrated check valve and locking ring as a matched assembly.
This assembly serves as the upper sealing and flow-control housing for the filter tank. The integrated check valve prevents backflow when the system is shut down, while the locking ring secures the filter head to the tank body, maintaining a sealed pressure vessel during operation. Replacing this assembly restores the filter's structural integrity, pressure retention, and backflow protection in a single service step.

Poolaroo Pro Tip
When installing this filter head assembly, inspect the tank O-ring seat and the mating surfaces of the tank body for cracks, warping, or mineral scale before seating the new head. A compromised seating surface will cause leaks regardless of how well the locking ring is tightened. Clean the seat thoroughly and ensure the locking ring engages evenly around its full circumference before applying operating pressure.
