Repair Kit for Watts Series 800

This kit services Watts Series 800 vacuum breakers in the M4 or 1/2 to 3/4 in sizes. It supplies the bonnet O-ring and the float vent disc assembly with vent float seal and spring. The parts restore the anti-siphon function on compatible bath faucets. It is not for fixtures that use a different series or connection size.

Thermals Noise and Power Draw

This is a passive plumbing component with no electrical or thermal characteristics. It adds no heat, noise or power draw to the installation. Buyers needing an active venting device should look elsewhere.

Replaces Worn Internal Parts

The kit replaces the bonnet O-ring and float vent disc assembly inside an existing Series 800 breaker. The jump is worth it when the original seals leak or the vent float fails to seat. It does not replace the breaker body or adapt the fitting to a new pipe size.

Questions about this item

How do I install the float vent disc assembly in the Watts 800 vacuum breaker?

Remove the old bonnet, lubricate the new bonnet O-ring from the kit, seat the float vent disc assembly with its spring oriented upward, then hand-tighten the bonnet to avoid cross-threading.

Which parts in the 800M4 kit will need replacement again after extended service?

The bonnet O-ring and float vent disc assembly are the wear items; plan to replace both when you notice leakage or reduced vacuum-breaking performance.

What is the first limitation that appears when the vacuum breaker operates continuously under back-siphonage conditions?

The float vent disc assembly reaches its maximum travel and can no longer vent additional air, so the device relies on the spring return to reset before the next cycle.
