Watts 800M2 Vacuum Breaker Repair Kit

This kit provides genuine replacement components for Watts Series 800M2 vacuum breakers sized from 1/2 to 1 inch. It contains a bonnet O-ring, a check disc assembly with holder, and a check spring to restore proper backflow prevention. Professional installers and maintenance teams use it to keep irrigation and plumbing systems compliant.

Replaces worn internal seals and check mechanisms

When the original bonnet O-ring, disc assembly or spring degrade, the vacuum breaker can leak or fail to prevent back-siphonage. Installing this kit renews those parts without removing the valve body from the line. It is not suited for larger valve sizes, different series models or applications requiring a complete valve replacement.
