Zurn Wilkins 975XLU 1" Reduced Pressure Backflow Preventer (Bronze) - 1-975XLUS

Zurn  Wilkins 975XLU 1" Reduced Pressure Backflow Preventer (Bronze) - 1-975XLUS

The Wilkins 975XLU Reduced Pressure Principle Assembly (SKU: 1-975XLUS) is a 1" bronze backflow preventer engineered for high-hazard protection in non-potable and irrigation systems. This wye-pattern assembly is supplied with union ball valve shutoffs and a bronze Y-type strainer to simplify isolation, maintenance, and debris protection.

This assembly is ideal for irrigation, landscape, and other non-potable water systems where code-compliant reduced pressure protection is required. The union ball valves and Y-strainer make routine testing and maintenance faster, and the bronze body helps ensure long-term reliability in outdoor and mechanical-room installations. For installation, follow local plumbing codes and the manufacturer's specification sheet for testing intervals, orientation, and service procedures.

Q&A

Maintenance Tips

• Inspect regularly for leaks, corrosion, and relief valve discharge issues.
• Test at least annually by a certified tester to ensure proper reduced pressure zone performance.
• Flush the system periodically to remove sediment and maintain smooth operation of check valves.
• Clean strainers and internal components to prevent clogging and pressure loss.
• Replace worn seals, O-rings, or check assemblies with approved repair kits as needed.
• Protect from freezing and keep adequate clearance for maintenance, testing, and repairs.
