Watts 0864943 Repair Kit

The Watts 0864943 Repair Kit provides all essential components for rebuilding a 3/4" 25AUB water pressure reducing valve. As a veteran tech, you know that sediment buildup and mineral debris are the primary culprits for pressure creep or a total loss of regulation. This kit allows you to maintain the integrity of the 25AUB-RK-3/4 series without the cost of a full valve replacement. It is designed to handle high-demand residential and commercial applications where maintaining a consistent 50 PSI factory setting is critical for protecting downstream plumbing fixtures. Using the Watts 25AUB repair kit ensures that your lead-free water pressure regulator continues to operate with a functional thermal expansion bypass, preventing system spikes even under no-flow conditions. Integrating a new standard capacity pressure regulator kit restores the valve's ability to throttle flow effectively, eliminating the "whistling" noise often associated with worn-out seats or vibrating stems.

• Full Rebuild Capabilities: Includes a high-grade diaphragm, O-ring, union gasket, strainer, and all necessary gaskets to seal the bottom and strainer plugs.
• Optimized Performance: Restores the water pressure regulator to factory specifications, ensuring accurate PSI adjustment and stable downstream pressure.
• High-Quality Internals: Features a durable disc and seat assembly designed to resist the abrasive effects of "hard water" scale and pipe scale.
• Drop-In Compatibility: Specifically engineered for the Watts 25AUB series, ensuring all threads and tolerances match the original equipment for a leak-free fit.

• Why is my downstream pressure rising when no water is running? This "pressure creep" is typically caused by debris stuck on the valve seat or a ruptured diaphragm. Installing the 0864943 repair kit replaces these wear points to restore a tight seal.
• Does this kit include the strainer screen? Yes, the Watts 0864943 includes a replacement strainer screen, which is vital for protecting the internal mechanism from large particulate damage.
• Is this compatible with the Lead Free (LF) versions? Yes, the 25AUB-RK is the correct internal service kit for both the standard 25AUB and the LF25AUB 3/4" models.
