Watts 0887298 Repair Kit

The Watts 0887298 Total Repair Kit (Model RK 009-T) provides all necessary internal components to restore the functionality of a 1/2-inch Series 009 Reduced Pressure Zone (RPZ) backflow preventer. This comprehensive kit is engineered for field technicians performing required annual maintenance or repairing catastrophic seal failures. It includes the first and second check valve assemblies, the relief valve assembly, and all essential o-rings and seat gaskets. Maintaining the backflow preventer assembly with genuine OEM Watts 009 repair parts ensures the system meets local plumbing codes regarding potable water protection. Because these bronze-bodied valves often face mineral scaling or debris intrusion, the RK 009-T repair kit allows for a full internal rebuild without removing the valve body from the line. Precise tolerances on the check valve seats and the relief valve diaphragm ensure the differential pressure stays within the required 2.0 PSI threshold to prevent fouling and nuisance discharge.

• Full Internal Restoration: Includes both check modules and the complete relief valve assembly for a total system overhaul.
• OEM Compatibility: Specifically designed for the 1/2" Watts 009 and 009M2 series, ensuring a drop-in fit without field modifications.
• Material Durability: High-grade elastomers and stainless steel springs resist chloramines and thermal expansion for extended service life.
• Code Compliance: Restores the factory-certified safety ratings required for RPZ backflow preventer certification and site inspection.

Does this kit work for both the 009 and 009M2 models?
Yes, the 0887298 kit is compatible with the standard 1/2-inch 009 and 009M2 series reduced pressure zone assemblies.

Why is my relief valve still dripping after installing the kit?
Continuous discharge usually indicates debris is trapped in the first check valve or the seat is nicked. Ensure the bronze seats are cleaned or replaced if the check valve assembly does not seal completely.

Do I need special tools to replace the check modules?
Standard hand tools are sufficient for the 1/2-inch series, though a seat removal tool is recommended if you find the internal seats are damaged and require replacement beyond what is in the standard kit.
