Hayward CHXRLV1930 – ¾″ Male Pressure Relief Valve
Product Overview
The Hayward CHXRLV1930 is a factory-authorized replacement pressure relief valve used on select Hayward H-Series pool and spa heaters. It protects the heater and plumbing system by opening automatically if internal pressure rises above a safe operating level.
Key Features
- ¾″ male threaded relief valve for direct installation into compatible heater ports.
- Opens at a preset pressure to prevent heater and plumbing damage.
- OEM-grade component designed specifically for Hayward heating systems.
- Durable metal construction suitable for high-temperature and chemical environments.
Technical Specifications
- Part Number: CHXRLV1930
- Connection: ¾″ male NPT
- Application: Pressure relief valve for select Hayward H-Series heaters
- Material: Metal safety valve assembly
Applications & Compatibility
The CHXRLV1930 valve fits multiple Hayward H-Series heater models, including various millivolt and electronic ignition versions. It is commonly used on H150, H200, H250 and similar models. Always verify your heater’s parts list to confirm compatibility prior to ordering.
Installation Instructions
- Turn off all power and shut off gas to the heater before servicing.
- Allow the heater to cool completely and relieve any pressure in the system.
- Unscrew the old relief valve from its port.
- Apply appropriate thread sealant or Teflon tape to the new valve threads.
- Thread the new CHXRLV1930 valve into place and tighten securely by hand or with a wrench (without overtightening).
- Restore power and gas, then run the heater briefly to check for leaks.
Troubleshooting
- Valve dripping or seeping: Verify the valve is tightened correctly and that thread sealant is properly applied.
- Valve opening frequently: Investigate underlying system pressure issues such as restricted flow, dirty filter or pump problems.
- No relief function: Replace immediately—relief valves that do not open properly pose a safety risk.
Maintenance Tip
Inspect the pressure relief valve during annual heater service. Replace immediately if signs of corrosion, leaking, or mechanical sticking are present. Maintaining a functioning relief valve is essential for safe and reliable heater operation.
