General Specifications
An air admittance valve shall be acceptable as a vent termination for
any individual vent, common vent, circuit vent, loop vent, island fixture
vent, vent stack or stack vent that is provided to prevent siphonage of
a fixture trap.
An AAV is used as an alternative to secondary venting through the
roof open to atmosphere and to prevent sewer gases from escaping
into a building. Additionally, it is a one-way valve designed to allow
air to enter the plumbing drainage system when negative pressure
develops in a piping system without the use of a vent extended to
open air. The device shall close by gravity and seal the vent terminal
at zero differential pressure (no flow conditions) and under positive
internal pressures.
Product Location Specifications
· Should be located a minimum of 4" above the weir of fixture trap for
single fixture and branch venting and 6" above flood level of highest
fixture for stack venting
· Each valve should be installed in an accessible location
