Rwc 23576-0150 Tp Relief Valve 150 Psi 3/4 Inch

Product Description

The RWC 23576-0150 is a temperature and pressure relief valve designed for residential and light commercial water heating systems. Built around the NCLX-5 platform, it features a cast bronze body with brass and stainless steel internal components, a silicone seat disc, and a stainless steel spring. The valve operates automatically, opening to relieve excess temperature or pressure and re-seating once conditions normalize. Rated at 150 psi, the 3/4-inch valve includes a test lever for field verification of function. Licensed plumbers and HVAC technicians install this valve as a required safety device on water heaters and hydronic systems.

The 23576-0150 is suited for residential and light commercial water heater installations where a reliable T and P relief valve is required by code. The NCLX-5 series incorporates an inert thermal element coating that provides effective isolation from mineral deposits, making it well suited for installations in areas with hard water or elevated mineral content in the water supply. The valve is available with male inlets and female outlets, and comes in several shank and element length options to match varied tank configurations.

Key Features

• Cast bronze body with brass and stainless steel internal parts for corrosion resistance
• Silicone seat disc provides a reliable, re-seating seal after pressure or temperature relief events
• Stainless steel spring maintains consistent valve performance over time
• Inert thermal element coating resists mineral deposit buildup and liming
• Integrated test lever allows field verification without additional tools
• Fully automatic operation — re-seats after temperature or pressure relief

Compatibility

Designed as an OEM-style replacement or new-installation T and P relief valve for residential and light commercial water heaters requiring a 3/4-inch connection rated at 150 psi.

Installation Notes

Installation of temperature and pressure relief valves is typically performed by a licensed plumber in accordance with local plumbing codes and ASME requirements. Shut off water supply and allow the system to cool before replacing an existing T and P valve. The discharge port must be piped to a safe drain location per IPC and local code requirements — never cap or plug the discharge outlet. Use thread sealant rated for potable water on inlet threads only.
