Rheem Temperature & Pressure Relief Valve – Certified Safety for Pressurized Hot Water Systems
The Rheem T&P Relief Valve is a critical safety device engineered to protect tank-type water heaters from excessive internal temperature and pressure conditions. This factory-calibrated valve opens at 210°F and 150 psi, discharging water to prevent tank damage and ensure compliance with national plumbing and mechanical code requirements.
Constructed with a forged bronze body and corrosion-resistant components, this valve is suitable for installation in residential or light commercial water heating systems. It meets ASME and CSA safety standards and includes a test lever for periodic functional checks.
Professional Features
- Dual Relief Function – Opens automatically at 210°F or 150 psi to protect the water heater tank from overpressure or overheating
- Rugged Brass Construction – Designed for durability in high-temperature potable water environments
- Manual Test Lever – Allows for field verification of valve operation and drainage system integrity
- Code Compliant – ASME Section IV rated and CSA listed for pressure relief in hot water storage tanks
- Universal NPT Threads – 3/4″ male inlet and 3/4″ female outlet for compatibility with standard tank tappings
Technical Specifications
- Relief Temperature: 210°F (99°C)
- Relief Pressure: Factory-set at 150 psi (10.3 bar)
- Body Material: Bronze
- Inlet Connection: 3/4″ MNPT
- Outlet Connection: 3/4″ FNPT
- Approvals: ASME Section IV, CSA B125.3
Installation Considerations
The T&P valve should be installed in accordance with local codes on the designated relief port of the water heater. Discharge piping must be routed to a safe drainage location, sloped for gravity drainage, and not capped or restricted. Installation by a licensed plumber is recommended to ensure code compliance and proper performance.
Typical Applications
- Residential and commercial tank-type water heaters
- Booster tanks or indirect storage tanks
- Replacements or OEM upgrades where a 3/4″ T&P valve is required
