Watts 007 M1 First Check Repair Kit

This repair kit fits Watts Series 007 M1 backflow preventers sized from 1-1/2 to 2 inches. It contains the check cage, cover O-ring, disc assembly, seat, seat O-ring and spring needed for a complete first check valve overhaul. Plumbers and facility managers use it to restore proper flow direction without replacing the entire valve body. The kit addresses wear that can allow reverse flow in potable water systems.

Normal operation thermals noise and power

The kit consists of passive mechanical components that generate no heat, noise or electrical draw during service. Installation requires only standard hand tools and the existing valve body pressure rating governs system limits. No external power source or cooling is involved in the repair process. California Proposition 65 warns that the product contains a chemical known to cause birth defects or other reproductive harm.

Compatibility limited to Series 007 M1 1-1/2 to 2 in

This kit fits only Watts Series 007 M1 valves in the 1-1/2 to 2 inch size range. It will not work with other Watts series, different manufacturers or larger valve sizes. Buyers needing parts for other series or pipe diameters must source the correct model-specific kit. Verify the valve series and size stamped on the body before ordering.

Questions about this item

How do I install the first-check repair kit on a Watts 007 M1 valve, and what step is often missed?

Shut off the water supply, relieve pressure, remove the cover, then replace the check cage, disc assembly, seat, both O-rings and the spring; the step most often missed is lubricating the new cover O-ring before reassembly.

Which parts in the Watts 007 M1 first-check kit will need replacement again over time?

The disc assembly, seat, both O-rings and the spring are wear items; the check cage typically lasts longer unless damaged by debris.

What limit appears first on a Watts 007 M1 valve when the first-check components wear under sustained use?

The disc assembly and seat O-rings degrade first, allowing back-flow past the check valve and triggering a failed test.
