Watts 800 M4 Vent Kit

This transparent vent kit is designed for use with Watts Series 800 M4 assemblies. It provides a direct replacement component for maintaining proper venting function in plumbing systems. The kit includes the bonnet O-ring and float vent disc assembly with vent float seal and spring. It is supplied new and ready for installation.

For maintenance of Series 800 M4 units

This kit suits plumbers or facility managers servicing existing Watts Series 800 M4 vacuum breakers in one-inch configurations. It restores the venting mechanism when the original components wear or fail. Buyers needing a complete vacuum breaker assembly or a different series compatibility should look elsewhere. The product is restricted from sale in certain jurisdictions due to chemical content regulations.

Sustained load behaviour

Under continuous system pressure the float vent disc assembly regulates airflow to prevent vacuum formation. The bonnet O-ring maintains a consistent seal during repeated cycling. The transparent housing allows visual confirmation of float movement without disassembly. The included spring ensures reliable return action over extended service periods.

Questions about this item

Which Watts valve series must I already have installed for this kit to fit?

The kit is made for the Watts Series 800 M4 vacuum breaker, so that valve body must already be in place.

Will the bonnet O-ring and float vent disc assembly in this kit replace the original parts on an older Series 800 M4 unit?

Yes, the kit includes a bonnet O-ring and a float vent disc assembly with vent float seal and spring that match the original Series 800 M4 components.

After installing the repair kit, how can I confirm the vacuum breaker is operating correctly?

Pressurise the line and watch for leakage at the bonnet; a properly sealed repair will hold pressure without water escaping through the vent.
