I am currently renovating a 1940s home 100% solo. I am adding two bathrooms back to back and was wondering how to avoid turning my roof into a pincushion of vent stacks. All and all I want to do things the right way but what is the best way to reduce the amount of vents through the roof? Can I just put a single 3" stack through the roof that all fixtures connect to in the attic? I would use AAVs but they say you have to provide access to them and I won’t be having any vanities to tuck them into (all pedestal sinks). Can you put AAVs in the attic? Thanks for any advise!
