Function
Float type automatic air vent designed to vent air from water at high
points in plumbing system piping. Example applications include risers,
domestic hot water storage tanks and recirculation system pump
inlets.
The automatic air vent is installed in the vertical position in parts of
the system where a concentration of air pockets is to be expected. It
is supplied complete with a safety hygroscopic cap that automatically
closes the air discharge in case of contact with water.
This vent is certified by ICC-ES to be in compliance with the International
Plumbing Code (IPC), International Residential Code (IRC), Uniform
Plumbing Code (UPC), National Plumbing Code of Canada (NPC). It
is certified by ICC-ES to be in compliance with standard NSF/ANSI
372-2011, California Health and Safety Code 116875 S.3874 (AB1953),
and Vermont S152.
