Watts 0887793 Total Repair Kit

The Watts 0887793 RK 009M2-T 1" Total Repair Kit provides a comprehensive solution for servicing the 1-inch Watts Series 009 reduced pressure zone (RPZ) backflow preventer. Designed for field technicians, this kit addresses common failure points in potable water applications and industrial plumbing systems where high-hazard cross-connection control is required. The kit features a modular check assembly design, facilitating efficient component replacement without removing the valve body from the line. Each component is engineered to withstand the rigorous pressure differentials necessary to maintain the air gap and prevent back-siphonage or backpressure backflow. This 009M2 total repair kit includes all necessary EPDM rubber parts, check seat O-rings, and stainless steel springs to restore the assembly to original factory specifications. Utilizing genuine Watts 0887793 replacement parts ensures consistent seating performance and long-term backflow preventer maintenance reliability under varying thermal and hydraulic loads.

Key Benefits for Contractors

• Comprehensive Service Coverage: Includes all internal components for both the first and second check valves, plus the relief valve assembly.
• Durable Material Composition: High-grade elastomers and stainless steel springs provide superior resistance to scale buildup and chemical degradation.
• Streamlined Installation: Designed for an exact fit within the 1-inch RK 009M2-T housing, reducing labor time during annual testing and certification.
• Reliable Pressure Regulation: Ensures precise relief valve opening points to maintain the required safety factor in high-hazard environments.

Common Questions

Is this kit compatible with the original Series 009 or only the M2 version?
This kit is specifically engineered for the 1" 009M2-T series. While many components look similar across Watts generations, the seat dimensions and relief valve stem designs are specific to the M2 series backflow preventer to ensure proper sealing pressure.

Does this kit resolve a constant drip from the relief valve discharge?
Yes, a constant discharge usually indicates a fouled first check or a compromised relief valve diaphragm. This total repair kit replaces all check valve rubber parts and the relief valve seat, which typically corrects discharge issues caused by debris or seat wear.

What is the difference between a total kit and a rubber-only kit?
While a rubber kit only provides O-rings and diaphragms, the Watts 0887793 includes the check springs and check modules, which is recommended if the unit has been in service for several years or has undergone significant thermal cycling.
