Rheem Temperature & Pressure Relief Valve – Code-Compliant Protection for Pressurized Hot Water Systems
The Rheem Temperature & Pressure (T&P) Relief Valve is engineered to safeguard water heaters by discharging water when internal temperature or pressure exceeds system design limits. This factory-set safety device is rated to relieve at 210°F and up to 150 psi, protecting against potential tank rupture and ensuring compliance with plumbing safety codes.
Constructed with a corrosion-resistant bronze body, this valve is suitable for use in residential and commercial storage tank applications and includes a manual test lever for periodic system checks.
Contractor-Grade Features
- Dual Relief Protection – Opens automatically at 210°F or when pressure exceeds rated limit
- Heavy-Duty Brass Body – Forged construction for long service life in hot water environments
- Manual Test Lever – Allows easy verification of valve operation and drainage system function
- Standard Threading – 3/4″ male NPT inlet and 3/4″ female NPT outlet for compatibility with common water heater ports
- Certified for Performance – ASME Section IV rated and CSA B125.3 listed for pressure relief compliance

Installation Requirements
This valve must be installed in the designated relief port of a tank-style water heater. Discharge piping should be properly routed to a safe drain location per local code. For safety and compliance, installation should be performed by a licensed plumbing professional. Improper installation can lead to valve failure or unsafe pressure conditions.
Typical Use Cases
- OEM replacement for Rheem, Ruud, and Richmond electric or gas storage water heaters
- New installations where ASME-rated pressure relief is required
- Code-compliant upgrades for aging or corroded relief valves
