Wilkins 12-P1500XL Pressure Relief Valve 0.5 in Lead Free

Product Description

The WILKINS 12-P1500XL is a lead-free pressure relief valve designed to protect plumbing systems from overpressure conditions. When system pressure exceeds the set point, the valve opens and discharges fluid to relieve excess pressure, then reseats once normal operating pressure is restored. At 0.5 inches in size, this valve fits standard residential and light commercial plumbing lines. It is installed by licensed plumbers as part of water heater assemblies, boiler systems, and potable water distribution lines where code-mandated pressure protection is required. The lead-free construction meets current safe drinking water standards.

The 12-P1500XL is suited for residential and light commercial plumbing applications where a compact, code-compliant pressure relief valve is needed. Typical installations include water heater discharge lines, pressure-reducing valve bypass assemblies, and domestic hot and cold water supply systems. Its 0.5-inch connection size makes it a practical fit for branch lines and smaller-diameter service runs commonly found in residential construction and retrofit projects.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before removing any existing valve or making new connections. Do not plug, cap, or restrict the discharge outlet of the relief valve. Ensure the discharge pipe directs flow to a safe, visible drain point as required by code.
