Watts 009 M2 1 Total Relief Kit

The Watts 009 M2 1 Total Relief Kit is a complete rebuild package for Watts Series 009 backflow preventers. It contains every internal component required for a full service, including the cover O-ring, RV spring, seat, seat O-ring, stem and diaphragm assembly, and stem O-ring. This kit suits maintenance technicians and facility managers responsible for cross-connection control compliance.

Replaces all wearable internals in a single service

This kit replaces the diaphragm, seat, spring, stem and all associated seals at once, eliminating the need to source parts individually. The jump is worth it when a test reveals leakage, chatter or reduced flow, or during the scheduled annual rebuild mandated by many local codes. It is not for installers needing only a single O-ring or those servicing a different valve series.

Straightforward bench rebuild with common tools

Installation is a standard bench procedure: remove the cover, swap the stem assembly, seat and spring, then reinstall the cover with the new O-ring. What usually goes wrong is reusing the old seat O-ring or misaligning the diaphragm, both of which cause immediate test failure. The kit includes every seal so nothing is left to chance.

What is the correct order to reassemble the stem and diaphragm assembly after replacing the seat and O-rings?

Install the new seat with its O-ring, then the RV spring, followed by the stem and diaphragm assembly and stem O-ring, finishing with the cover O-ring.
