Hayward CLX220EA – Check Valve & Inlet Fitting Adapter Assembly for CL200/CL220 Chlorinators
The CLX220EA is a genuine OEM check-valve/inlet-adapter assembly made for Hayward CL-series (CL200 / CL220) salt or chemical feeders. It ensures proper water flow to the feeder and prevents backflow of pool water — protecting equipment and ensuring safe, controlled chemical distribution.
Key Features
- Integrated check valve — prevents pool water from siphoning back into the chemical feeder when the pump stops.
- Inlet fitting adapter — connects the feeder to the plumbing, supplying consistent chemical feed under pressure.
- OEM-spec part — ensures correct fit and compatibility with Hayward CL-series feeders and existing plumbing.
- Simple installation — replaces old or damaged adapters to restore safe chemical flow and back-flow protection.
Specifications
- Brand: Hayward
- Part Number: CLX220EA
- Type: Check valve + inlet fitting adapter assembly
- Compatible With: Hayward CL200, CL220 and related off-line/in-line chlorinator systems
- Typical Application: Prevent chemical feeder backflow, secure chemical delivery, restore check-valve function
When to Use / Replace
Replace this assembly if your chlorinator or feeder is leaking, if the check valve is stuck or nonfunctional, or after a feeder installation when plumbing changes are made. A functioning check valve is essential to prevent corrosive back-flow and protect pool equipment from chemical damage.
Installation & Maintenance Tips
- Shut off pump and relieve system pressure before removing old parts.
- Remove the existing inlet adapter and check valve, clean connection points, and install the new CLX220EA assembly per manufacturer instructions.
- Verify correct orientation — check valve must face downstream toward the feeder to block back-flow.
- After installation, run the system and inspect for leaks; ensure chemical feed lines stay dry when the pump is off.
