Wilkins 112-975XL2 Backflow Preventer 1-1/2 Inch Fnpt Bronze

Product Description

The WILKINS 112-975XL2 is a reduced pressure zone (RPZ) backflow preventer designed for potable water systems where cross-contamination prevention is required by code. Built with a bronze body and featuring FNPT end connections in a 1-1/2 inch nominal size, this assembly uses a quarter-turn ball valve design for straightforward shutoff. RPZ assemblies like this one provide the highest level of backflow protection, making them the standard choice for commercial and industrial plumbing installations where backsiphonage or backpressure hazards exist.

This backflow preventer is suited for domestic water service applications in commercial buildings, light industrial facilities, and residential plumbing systems where local codes require reduced pressure protection. The FNPT end style allows direct threaded connection to standard pipe, and the quarter-turn ball valve shutoffs simplify isolation during testing and annual inspection. Licensed plumbers and backflow prevention specialists are the typical installers for this type of assembly.

• Reduced pressure zone design provides maximum backflow protection for potable water lines
• 1-1/2 inch nominal FNPT threaded end connections for standard pipe compatibility

Installation Notes

Installation must be performed by a licensed plumber or certified backflow prevention specialist in accordance with local plumbing codes and ASSE 1013 standards. Shut off the water supply and relieve system pressure before beginning installation or service. The assembly must be installed in an accessible location to allow for annual testing and inspection as required by most jurisdictions.
