    I live in a state that uses the NSPC.....
    I have read some of the code about venting but don't see any reference about the use of an AAV device.
    I live in an older home that was built with NO proper vent for most of the fixtures in the home.
    I have corrected some of this by adding a new proper vent thru the roof for the second floor bathroom fixtures....
    There is no way to add a proper vent for two kitchen sinks on the first floor or tie into either the original main stack vent or the new vent I installed.

    I have installed AAV's for both kitchen sinks as I have no other option.......

    Just wondering if this is would be accepted in this situation......
