Watts 800M4 Repair Kit

The Watts 800M4 1st Check Kit is a vacuum breaker repair package designed for Watts Series 800 M4 assemblies. It contains a bonnet O-ring, check disc assembly with disc and holder, and a check spring for restoring proper backflow prevention function.

Replaces worn internal components

This kit replaces deteriorated seals and check mechanisms inside the vacuum breaker. The jump is worth it when the existing bonnet O-ring leaks or the check disc assembly fails to seat, causing discharge or loss of protection.

Suits maintenance on Series 800 M4 units

It suits plumbers and facility managers servicing Watts Series 800 M4 vacuum breakers. It does not suit installations using other series or models, nor buyers needing a complete valve replacement rather than internal repair parts.

Yes, the repair kit contains the bonnet O-ring, check disc assembly with disc and holder, and the check spring for the Series 800 M4 1 in unit.

How is the kit installed, and which step is often missed?
