Compatibility and Installation
This kit is specifically designed as a First Check Repair Kit for 3/4 inch Watts 009M3 Reduced Pressure Zone (RPZ) backflow preventer assemblies. It provides the essential components to replace the first check assembly and the cover O-ring for this particular model. Watts Series 009 backflow preventers have undergone several "modifications" (009, 009M1, 009M2, 009M3), and while they may appear similar externally, their internal components are distinct. It is critical to confirm your device is precisely a 3/4 inch 009M3 to ensure compatibility. No specialized tools are needed for the servicing process, making it a straightforward factory replacement.

Kit Contents
- Check Assembly (First Check)
- Cover O-ring
Watts Series 009 Reduced Pressure Zone Assemblies, including the 009M3 modification, are designed with a one-cover system where check modules slide into the body and are secured by a retainer. Over the years, Watts has made slight redesigns, creating "modifications" like the M3 model. It is crucial to ensure your backflow preventer is specifically a 3/4 inch 009M3 model, as internal parts differ significantly between modifications (009, 009M1, 009M2, 009M3).
