Watts 0881263 Repair Kit

Maintaining a high-capacity reduced pressure zone assembly requires a Watts 0881263 kit to address common failure points like mineral buildup and O-ring displacement. Also recognized as the 47BFP-RK, this factory replacement kit is engineered for the 900-1-1/2 series backflow preventer. When a unit displays nuisance dripping from the relief valve, it typically signals a fouled first check or a compromised second check valve. This comprehensive kit provides the necessary components to restore the internal pressure differential, preventing the reverse flow of non-potable water into the supply line.

For a veteran technician, the Watts backflow repair kit offers a precise fit for 1-1/2 inch and 2 inch 900 series assemblies. The 0881263 includes high-quality elastomers and springs designed to withstand fluctuating supply pressures and water hammer. Using the included maintenance tool and silicone grease ensures that first and second check valve modules seat correctly against the epoxy-coated body, eliminating leaks without the need for specialized external tools. Prioritize flushing the lines before installation to protect these new internal components from debris-related fouling.

• Universal Compatibility: The Watts 0881263 is identical to the 47BFP-RK, ensuring a perfect match for 1-1/2" to 2" 900 Series valves.
• Minimized Downtime: This complete repair kit includes everything from check valve assemblies to union nut gaskets, allowing for a total internal overhaul in one service call.
• Superior Materials: Engineered with heavy-duty springs and stem O-rings to handle the mechanical stresses of high-capacity thermal expansion and backpressure.

What is in the Watts 0881263 repair kit?
This Watts 47BFP-RK contains an inlet adapter gasket, first check valve assembly (with spring and O-ring), second check valve spring, two union nut gaskets, relief valve spring, second check valve assembly, stem O-ring, maintenance tool, and silicone grease.

Why is my Watts 900 series backflow preventer leaking from the relief valve?
A dripping relief valve usually indicates debris in the first check valve or a failed second check valve. If the dripping stops when you close the downstream shutoff, the second check is likely the culprit. This kit provides all components to fix both issues.

Is the 47BFP-RK the same as the 0881263?
Yes, the 0881263 is the specific ordering code for the 47BFP-RK repair kit, ensuring you receive the correct factory parts for 1-1/2" 900 series assemblies.
