Watts 0864946 Repair Kit

For contractors servicing high-capacity water systems, the Watts 0864946 Repair Kit (Model 25AUB-RK) is the essential OEM solution for rebuilding 2-inch Watts 25AUB-Z3 Series water pressure reducing valves. Maintaining line pressure integrity is critical in commercial and industrial plumbing, and this lead-free pressure regulator rebuild kit provides all necessary components to eliminate weeping, pressure creep, and hydraulic noise. The kit includes a high-durability diaphragm, diaphragm liner, disc, seat, union gasket, and O-rings, as well as the strainer and plug gaskets. Engineering precise setpoints requires high-quality internals; this 25AUB-RK 2" repair kit ensures your Watts 2" PRV continues to protect downstream fixtures from thermal expansion and excessive municipal head pressure. Utilizing genuine Watts replacement parts prevents compatibility issues often found with substandard aftermarket seals, ensuring a tight shut-off and reliable water pressure regulation across residential and commercial 2-inch supply lines.

Key Benefits for Technicians:

• Complete Internal Restoration: Includes essential wear items like the disc and seat assembly and diaphragm to fix pressure fluctuations.
• Code Compliance: Lead-free construction meets all safe drinking water standards for potable water systems.
• Extended Service Life: Targeted component replacement avoids the high cost of full 2-inch valve body replacement.
• Simplified Maintenance: Designed for standard field service without the need for specialized hydraulic tools.
• Universal Series Compatibility: Specifically engineered for the RK-25AUB-Z3 series 2" valves.

Common Technical Questions:

Does this kit include the strainer?
Yes, the 0864946 kit includes the replacement strainer and the corresponding strainer plug gasket, which are critical for preventing debris from fouling the seat.

How do I know if my 25AUB-Z3 needs a rebuild?
If you observe "creep" (static pressure rising above the setpoint) or water leaking from the vent hole in the spring cage, the internals or diaphragm have likely failed.

Is this kit compatible with other Watts PRV models?
This kit is specifically calibrated for the 2" 25AUB-Z3 series. Using these parts in different sizes or series may result in improper pressure regulation or seal failure.
