Watts 0887301 Repair Kit

The Watts 0887301 (RK 009M2-CK2) is a professional-grade second check repair kit engineered specifically for 1-1/4" and 1-1/2" Watts 009M2 Reduced Pressure Zone (RPZ) backflow preventers. This kit is essential for maintaining the mechanical integrity of the backflow preventer, ensuring the assembly continues to protect potable water supplies from high-hazard backsiphonage and backpressure. For technicians servicing LF009M2 or standard series 009 units, this kit provides direct-replacement internal components including a complete check assembly, a durable cover O-ring, and a sensing passage O-ring. Utilizing genuine factory parts is critical to maintaining the ASSE 1013 and AWWA C511-92 certifications of the existing valve. The modular check construction allows for efficient field service without the need for specialized tools, while the high-quality elastomer seat discs ensure positive seating under varying pressure differentials. Proper installation of this Reduced Pressure Zone assembly kit restores the low pressure drop performance and reliability of the secondary check module.

• Precise Compatibility: Specifically designed for 1-1/4" – 1-1/2" Watts 009M2 and LF009M2 series backflow assemblies.
• Complete Internal Refresh: Includes the second check assembly and necessary O-rings to address seal failure and pressure fluctuations.
• Lead-Free Construction: Complies with all lead-free requirements for potable water applications.
• Field-Serviceable Design: Modular components allow for rapid top-entry maintenance, reducing labor time for contractors.
• Standardized Compliance: Helps maintain backflow preventer compliance with USC and ASSE 1013 standards.

How do I know if I need the first check or second check repair kit?
Failing backflow tests usually pinpoint the culprit. Constant discharge from the relief valve often indicates a fouled first check, while backpressure failure or failing the second check test requires the Watts 0887301 kit. Always check the serial plate for the 'M2' designation to ensure correct sizing.

Are special tools required for the 009M2 second check replacement?
No, the 009M2 series features a single access cover and modular check construction that can be serviced with standard hand tools. Always ensure the system is depressurized before removing the stainless steel cover bolts.

Will this kit work on the Lead-Free (LF) versions of the 009M2?
Yes, this 0887301 repair kit is fully compatible with both the standard bronze 009M2 and the LF009M2 lead-free models in the 1-1/4" to 1-1/2" size range.
