• Maintenance Efficient: Simplifies field service, ensuring the reduced pressure zone assembly meets local plumbing codes during testing.

• Does this kit include parts for the relief valve? No, the 0887129 is a check rubber kit. To service the relief valve, you will need the RK 909-RV or a complete total rubber parts kit.
• Will this fit the 1-1/4" Watts 909? No, this kit is specifically sized for the 3/4" and 1" bodies. Larger sizes require the RK 909-M1 series kits.
• When should I replace these rubber parts? We recommend replacing the internal check valve rubber if the device fails its annual backflow test or if you observe constant dripping from the relief valve vent.
