First Check Valve Repair Kit

This kit restores the first check valve in Watts Series 007 M1 backflow preventers sized from 3/4 to 1 inch. It contains the check cage, cover O-ring, disc assembly, seat, seat O-ring and spring needed for a complete rebuild. Plumbers and facility technicians use it to return the assembly to working order without replacing the whole valve body.

Component-Level Restoration

The kit replaces the internal wear parts that degrade with age, debris or mineral buildup. Swapping these components is worthwhile when the valve body remains sound but the check mechanism no longer seals or opens reliably. It avoids the labour and cost of removing the full preventer from the piping system.

Sustained Service Performance

Once installed, the refreshed check valve resists continuous pressure cycles and flow variations in potable or irrigation lines. The included spring and disc assembly maintain consistent seating force over long periods, while the O-rings preserve a tight seal against the cover and seat. California Proposition 65 applies to this product.
