Second Check Valve Kit for Watts Series 009

This repair kit restores the second check valve on Watts Series 009 backflow preventers sized from 3/4 to 1 inch. It is intended for plumbers and facility managers maintaining potable-water assemblies. The package supplies the check assembly and cover O-ring needed for a complete rebuild. California Proposition 65 warns that the product contains a chemical known to cause birth defects or other reproductive harm.

Installation notes and common issues

Installation requires depressurising the system and removing the existing check assembly before fitting the new components. A frequent problem is reusing the old cover O-ring, which can leak after the repair. Another issue is misaligning the check assembly during reassembly, preventing proper sealing. Correct torque on the cover bolts and a clean seating surface avoid most callbacks.

Compatibility — Watts Series 009 3/4 to 1 inch only

This kit fits exclusively Watts Series 009 devices in the 3/4 to 1 inch size range. It will not work on other series, larger sizes or different manufacturers' valves. Buyers who need parts for a different series or a larger diameter valve must source the correct kit for that specific model.
