Description

Air Admittance Valves (AAV's) shall consist of a one-way valve designed to allow air to enter the plumbing drainage system when a negative pressure develops.  The device shall be closed by gravity under zero differential pressure (no flow condition) and seal under conditions of positive internal pressure.

Scope

This Standard establishes basic performance requirements and test procedures for stack AAVs used in plumbing drainage systems.


Note: AAVs for drain, waste, and vent stacks are designed to be installed on the top of stacks with six (6) branch intervals or less. Where these AAV's are installed, there must be at least one (1) vent which extends to the atmosphere outside the building serving the same drainage system.
