Question: How do I vent a new basement bathroom when there is no overhead vent line to tie into to carry out through the roof?
Back story: a double wide house put on a full basement foundation in 2007. Basement bathroom plumbing was roughed in at time of build. I am now finishing the basement off and do not know how to vent. I have toilet, sink, tub, and shower. I would really like to not use AAVs (even if they are allowed). There is one story above with vaulted ceilings so I do not have an attic to work in. There is a first floor bathroom directly above the basement bathroom with a vent through the roof.
Can I shoot a vent out the rim joists out the side, or do I have to open up the first story bathroom to tie in in the wall? Or any other ideas?
