Watts Series 007 Double Check Valve Repair Kit 3/4 to 1 in

Watts Series 007 Repair Kit

This kit provides replacement components for Watts Series 007 double check valve assemblies sized from 3/4 to 1 inch. It contains two disc assemblies, two seat O-rings and a cover O-ring to restore sealing performance. The parts are designed for direct fit during routine maintenance or repair work. Suitable for plumbers and facility managers servicing backflow prevention devices.

Verify valve series and size before ordering

Confirm that the installed backflow preventer is a Watts Series 007 unit with a nominal size between 3/4 and 1 inch. Check the model marking on the valve body to ensure compatibility with the disc assemblies and O-rings supplied. This kit does not fit other series or larger valve sizes. California Proposition 65 warning applies to the materials used.

Replaces worn internal seals and discs

The kit renews the critical sealing surfaces that degrade over time due to water chemistry and pressure cycles. Installing new disc assemblies and O-rings restores proper check valve operation and helps the assembly pass periodic test requirements. The upgrade is worth it when leakage, failed test results or visible wear are observed during inspection.
