Temperature and Pressure Relief Valve by Rheem.

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
