Watts 0886999 Rubber Parts Kit

For field technicians maintaining potable water systems, the Watts 0886999 Rubber Parts Kit is the industry-standard solution for rapid in-line servicing of 3/4 inch 009M2 reduced pressure zone assembly units. This comprehensive RK 009M2-RT repair kit provides all necessary elastomer components to restore seal integrity across the entire backflow preventer. The kit is engineered for full compatibility with both the lead-free LF009M2 and 009M2 Series, ensuring a precise fit for the backflow preventer rubber parts required during annual inspections or emergency leak repairs. As a total rubber parts kit 009M2-3/4, this package includes the diaphragm, two disc assemblies, stem O-rings, a cover O-ring, two seat O-rings, and the critical relief valve seat O-ring. By replacing these high-wear Watts 0886999 components, contractors can eliminate relief valve dripping and "spitting" caused by debris fouling or rubber degradation, maintaining system compliance with national plumbing codes without needing a full unit replacement.

• Full System Coverage: Includes all internal elastomer seals for both the first and second check valves plus the relief valve assembly.
• Direct Cross-Reference: 0886999 is identical to RK009M2RT-3/4, ensuring 100% compatibility with 3/4" 009M2 valve bodies.
• Optimized Performance: Prevents backflow preventer failure by replacing worn silicone discs and O-rings that lead to pressure loss.
• In-Line Serviceability: Designed for quick installation through the single access cover, reducing downtime for the contractor.

• Does this kit work for the 009M3 series? While the 009M2 and 009M3 share some body characteristics, this kit is specifically spec'd for the M2. Always check the nameplate as check valve designs vary between these generations.
• Why is my relief valve still dripping after full assembly? Ensure all seats were cleaned and O-rings were lubricated with FDA-approved silicone grease. Even minor debris or a pinched O-ring can prevent the tight seal required for RPZ units.
• How do I know if I need the total rubber kit versus just a check kit? If you are seeing discharge from the relief valve vent, it often indicates the need for a total rubber kit to address both the check modules and the RV diaphragm simultaneously.
