Vent Kit for Series 800 Vacuum Breakers

This Watts 800M3 vent kit repairs vacuum breakers in the Series 800 range. It fits models designated M3 or sized from 1/2 to 3/4 inches. The kit restores proper backflow prevention in bath plumbing systems. It is intended for maintenance professionals and experienced DIYers.

Includes Bonnet O-Ring and Float Vent Disc Assembly

The package supplies a bonnet O-ring and a complete float vent disc assembly with vent float seal and spring. These components replace worn internal parts without removing the valve body. No special tools beyond standard plumbing equipment are required. The repair returns the device to code-compliant operation.

Maintains Seal Integrity Under Continuous Pressure

The replacement seals and spring are built to withstand sustained supply pressure in residential and commercial bath installations. They resist degradation from constant water contact and temperature cycling. The kit addresses leaks that develop during prolonged service rather than brief pressure spikes. California Proposition 65 warning applies.
