Hayward CL-Series Check Valve with Inlet Fitting Adapter | CLX220EA

The Hayward CLX220EA is a genuine OEM check valve and inlet fitting adapter assembly for Hayward's CL-Series offline chlorine and bromine feeders. This two-component assembly performs two essential functions: the inlet fitting adapter connects the water supply line to the chlorinator's inlet port, and the built-in ball check valve prevents concentrated chlorinated water from backflowing into pool equipment — particularly heaters and heat exchangers — when the pump shuts off. Without a properly functioning check valve, highly concentrated chlorine can flow back through the plumbing during pump-off cycles, causing severe corrosion damage to heat exchangers and other sensitive pool equipment over time. Compatible with Hayward chlorinator models CL100, CL110, CL110BR, CL200, CL220, and CL220BR, the CLX220EA is a small but critical component that protects some of the most expensive equipment in any pool system.

Highlights

• Genuine Hayward OEM Assembly: Factory-authorized CLX220EA check valve and inlet fitting adapter manufactured by Hayward to exact OEM specifications — ensuring proper integration with CL100, CL110, CL110BR, CL200, CL220, and CL220BR offline chlorinator and brominator models.
• Prevents Backflow of Concentrated Chlorine: The internal ball check valve closes automatically when the pump shuts off, blocking highly concentrated chlorinated or brominated water from flowing backward through the plumbing — protecting heaters, heat exchangers, and other pool equipment from chemical corrosion damage.
• Critical Heater & Equipment Protection: A failed or degraded check valve is one of the most overlooked causes of premature heat exchanger corrosion — replacing a worn CLX220EA is a low-cost investment that helps extend the service life of far more expensive downstream pool equipment.
• Complete Adapter Assembly — Ready to Install: Includes the check valve, inlet fitting adapter, and compression nut, providing everything needed for a complete, leak-free replacement of the chlorinator's inlet connection in one convenient assembly.
• Broad CL-Series Chlorinator Compatibility: Fits the full range of Hayward's most widely installed offline chlorine and bromine feeders — CL100, CL110, CL110BR, CL200, CL220, and CL220BR — making it one of the most universally needed replacement parts in the Hayward chlorinator parts catalog.
