Watts 007 M3 3/4 Double Check Valve Repair Kit

Repair Kit for Watts Series 007 M3 3/4 Valves

This kit supplies the internal rubber components required to service a Watts Series 007 double check valve assembly in the M3 or 3/4 inch size. It is intended for plumbers or facility managers performing scheduled backflow preventer maintenance. The package contains two disc assemblies, two seat O-rings and one cover O-ring.

Rubber Components Designed for Direct Replacement

Each elastomer part matches the original equipment dimensions so the valve reseals without modification. The discs and O-rings install inside the existing body using standard hand tools, allowing the repair to be completed without removing the valve from the pipeline. Fresh rubber restores the tight shut-off needed for cross-connection control.
