This kit provides the internal components needed to service a Watts Series LF909 backflow preventer. It fits valves sized from 1-1/4 inches to 2 inches with the M1 designation. The package includes a cover O-ring, disc assembly, lubricant, seat, seat O-ring and spring. All parts comply with NSF lead-free requirements.

Repair scope limited to first check valve

The kit addresses only the first check valve assembly within the LF909 unit. It does not contain parts for the second check valve, relief valve or shut-off handles. If those sections are worn, additional kits will be required. The included lubricant is intended solely for the supplied O-rings and seat during reassembly.
