Watts 0887547 Rubber Parts Kit

The Watts 0887547 (RK 009-M2-RT) is a critical backflow preventer repair kit designed specifically for the maintenance of 2-inch Series 009-M2 reduced pressure zone assemblies. When servicing an RPZ, replacing the elastomer components is a standard preventative measure to address persistent relief valve weeping or failure to hold tight against backpressure. This rubber parts kit includes the essential check valve O-rings, cover O-rings, and the relief valve diaphragm required for a complete internal overhaul. Utilizing 0887547 ensures the assembly maintains its ASSE 1013 compliance and operational integrity under variable pressure conditions. Professional contractors should note that this kit (also referenced as 887547) is engineered for the M2 design iteration; verify the nameplate on the brass body to confirm the series, as non-M2 components are not interchangeable. High-tolerance EPDM and silicone components provide the necessary chemical resistance and sealing memory for long-term potable water system protection.

• System Restoration: Stops external relief valve discharge and internal cross-connection risks by replacing worn check and relief valve seals.
• Exact OEM Fit: Specifically machined for the 2" Series 009-M2, preventing the bypass leakage often found with generic aftermarket seals.
• Comprehensive Contents: Includes all necessary O-rings and the relief valve diaphragm for a standard semi-annual or annual service interval.
• Material Durability: High-grade elastomers are designed to withstand thermal expansion and pressure fluctuations common in commercial plumbing headers.

What is included in the Watts 0887547 repair kit?
This kit contains the rubber elastomers only: two check valve O-rings, one relief valve diaphragm, and the cover O-rings. It does not include the check valve springs or seats.

Will this rubber parts kit work for the standard 009 series?
No, the 0887547 is specifically for the 009-M2 modified design. Standard 009 and 009-M1 units require different part numbers due to variations in seating surface dimensions.

How do I know if I need the full total repair kit or just the rubber parts kit?
If the metallic seats and springs show no signs of scale build-up, pitting, or fatigue, the 0887547 rubber parts kit is the cost-effective solution for restoring a "pass" status during backflow testing.
