AAV as a vent on a main waste stack
We have two waste stacks in our house.
One is used as a main stack for solid waste (serving two full baths and a powder room), while the other was used for kitchen sink and laundry sink.
During renovation they cut out the vent for the secondary stack (the one that serves kitchen and old laundry sink). I was told that the plumber plans to use AAV on the secondary stuck in lieu of the vent that is gone (both kitchen sinks that will drain to this stuck will also have AAV on them so there will be no traditional vent on any of the fixtures that will drain to that stack). Laundry sink had no individual vent (was utilizing the vent that was cut off). Is this OK? I am in CT.
