Installation Instructions
- 【COMPLETE INSTALLATION KIT】 Unlike other pressure reducing valves that leave you with missing parts, Our 1-1/4 inch PRV comes with TWO complete union nut sets – one for each side of the valve. Open the box and install immediately. No searching for missing tailpieces, no frustration. We include everything you need to get the job done right the first time. Replacement for Zurn 114-NR3XLDU and NR3XL series. Fits 1-1/4 inch copper, PEX, and CPVC plumbing with FNPT connections.
- 【BRONZE CONSTRUCTION + STAINLESS STEEL STRAINER】 Built from corrosion-resistant bronze for long-lasting performance in water systems. The robust body withstands high inlet pressures up to 400 PSI and temperatures up to 140°F. Integrated stainless steel strainer traps sediment, debris, and particles before they can damage your pipes, faucets, and appliances. This 2-in-1 protection extends the service life of your entire plumbing system and reduces maintenance costs over time.
- 【SPACE-SAVING DESIGN】 This 114-NR3XLDU pressure reducing valves 6.85" length, 3" width, and 7.5" height ensures a perfect fit in tight spaces under sinks and in utility closets. Dual union FNPT connections match standard 1-1/4 inch plumbing systems. Factory preset to 50 PSI with an adjustable range of 15-75 PSI to meet your specific water pressure needs.
- 【PROTECT YOUR HOME & EASY ADJUSTMENT】 Excessive water pressure damages pipes and wastes water. Factory preset to 50 PSI (adjustable via the center bolt). Critical Adjustment Tips: (1) Always use a downstream pressure gauge (like Model HGJ-25) when adjusting; (2) Turn bolt clockwise to RAISE pressure, counter-clockwise to LOWER; (3) NEVER bottom out the adjustment bolt against the bell housing to avoid internal damage. Consistent pressure protects fixtures and reduces water waste.
- 【TROUBLESHOOTING & MAINTENANCE KIT】 If outlet pressure slowly creeps up, clean the cartridge strainer (instructions included). If pressure jumps immediately to supply pressure, the cartridge may need replacing. Note: Pressure rise during water heater operation is normal thermal expansion – consider installing an expansion tank. Complete kit includes 2 union nuts + 2 gaskets for a hassle-free install.
