Watts 0886011 Repair Kit

Maintain peak performance and system reliability with the Watts 0886011 Repair Kit, specifically engineered for the RK9DM3-T dual check valve with atmospheric vent. This professional-grade service kit is essential for addressing common failure points in 1/2-inch Series 9D backflow preventers, particularly when faced with continuous discharge from the atmospheric vent or debris-related seal failure. Designed for veterans in the field, this comprehensive bundle includes a high-durability diaphragm assembly, disc assembly, seat, seat O-ring, and two union seals to ensure a leak-free reassembly. These components are factory-rated for non-potable water applications, making them the standard choice for heating systems and industrial fluid management. Utilizing genuine replacement parts ensures exact clearance tolerances and material compatibility with the Watts RK9DM3-T body, preventing the pressure differential fluctuations that lead to premature wear. For contractors performing scheduled maintenance or troubleshooting fouled check valves, this kit provides everything required to restore atmospheric vent backflow preventer functionality without specialized tooling.

Key Benefits:

• Ensures accurate seating and pressure differential in 1/2" dual check valves.
• Includes a complete diaphragm and disc assembly for total internal overhaul.
• Restores the functionality of the intermediate atmospheric vent to prevent floor flooding.
• Optimized for high-temperature and hydraulic pressure demands found in HVACR boilers.
• Directly compatible with 0886011 and legacy series 9DM2 and 9DM3 units.

Common Questions:

Does this kit resolve a dripping atmospheric vent?
Yes, a dripping or leaking vent often indicates debris accumulation or a fouled second check valve. Replacing the internal components using this kit typically restores the seal and stops the discharge.

Is the Watts 0886011 suitable for potable water systems?
No, this specific series is designated for non-potable applications. It does not meet the low-lead requirements of the Safe Drinking Water Act for human consumption systems.

Are special tools required for the RK9DM3-T installation?
No specialized tools are required. The assembly is designed for straightforward field service, though standard wrenches and O-ring lubrication are recommended for a proper seal.
