Installations
This valve is designed for installation in a continuous pressure
potable water supply system 12” above the highest point of the
downstream piping. The valve must be installed with the supply
connected to the bottom and in a vertical position. Allow adequate
space for periodic inspection, servicing or testing. The valve should
not be installed in an area where freezing or spillage will cause
damage. Adequate drainage/freeze protection must be provided in
cold weather applications. 1.5psi (.10 bar) must be exerted against
the float spring to seal the float and air inlet. Do not undersize sup-
ply and discharge piping.
Vacuum breakers are not desiged, tested or
approved to protect against backpressure backflow or water ham-
mer shock. For protection against backpressure backflow, install
Watts 909/009 Reduced Pressure Zone Backflow Preventer. For
Protection against water hammer shock install a Watts Series 15
Water Hammer Arrestor utilizing good plumbing practice.
