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.

Questions about this item

Which Watts Series 009 models does the 1-inch Total Relief Kit fit?

The kit is made for Watts Series 009 valves in the M2 or 1-inch sizes, covering both variants with a single package.

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.

How often should the rubber diaphragms and O-rings in this relief kit be inspected or replaced?

Inspect the diaphragm, seat O-ring, stem O-ring and cover O-ring annually; replace any that show cracking, hardening or loss of elasticity to maintain proper relief function.
