About This Item
The Hayward Check Valve (ECX4077B1) is the OEM replacement check valve for select StarClear cartridge filters and Perflex Extended-Cycle DE filters.
This check valve is installed within the internal plumbing of the compatible filter tank assembly, maintaining the one-way flow path specified by Hayward for these filter models. It is sized and configured specifically for the StarClear and Perflex DE filter housings listed below — it is not a universal or field-adjustable component.

Poolaroo Pro Tip
When replacing this check valve, inspect the mating surfaces and seating area inside the filter housing for cracks, debris, or wear before installing the new part — a poor seal at this joint is a common source of air lock or pressure loss in StarClear and Perflex DE filter systems.
