Watts 0887185 Rubber Parts Kit

The Watts 0887185 (RK 009-RT 1 1/4-2) is a comprehensive rubber parts kit engineered for the field service and maintenance of 1 1/4" to 2" Watts 009 Series Reduced Pressure Zone (RPZ) assemblies. Designed for high-performance backflow prevention, this 009-RT-RK repair kit includes all necessary elastomeric components to restore the seal integrity of both the first and second check valves, as well as the relief valve assembly. This kit is a direct replacement for 887185 and is compatible with standard 009 and LF009 models. Utilizing genuine Watts backflow parts ensures precise fitment and adherence to original equipment specifications, which is critical for maintaining the safety of potable water systems against backsiphonage and backpressure.

This Watts repair kit features high-grade rubber components, including disc assemblies and O-rings, to address common failure points such as relief valve spitting or consistent weeping. By replacing worn internal seals, contractors can extend the service life of the backflow preventer without requiring a full valve replacement. Pro-tip for technicians: ensure all surfaces are seated correctly and lubricate O-rings with FDA-approved silicone grease during reassembly to provide a leak-free seal and prevent binding in the sensing passage.

• Complete Seal Restoration: Includes both check assembly O-rings, disc assemblies, and the relief valve diaphragm for a total system overhaul.
• Broad Compatibility: Specifically designed for 1-1/4 to 2 inch Watts 009 reduced pressure zone assemblies, including lead-free variants.
• OEM Reliability: Genuine Watts 0887185 components ensure dimensional accuracy and material compatibility with the valve body.
• Internal Component Maintenance: Prevents bypass and maintains the required pressure differential between the supply and the zone.

What causes the relief valve to discharge water?
Continuous dripping usually indicates a fouled second check valve or debris on the relief valve seat, while intermittent spitting often points to supply pressure fluctuations or a fouled first check valve.

Does this kit work for the Lead Free (LF) versions?
Yes, the 0887185 rubber parts kit is compatible with both the standard 009 and the LF009 series in the 1 1/4" to 2" size range.

Are special tools required for installation?
No, these kits are designed for straightforward field service. Standard tools are sufficient to access the single-cover top-entry design of the 009 series.
