Plumbing/code experts-
I am looking to redo the bathroom in my basement. Currently 3 drains exist (toilet, shower, and sink) and none are tied into a vent stack. They are close to the main 4" sewer line (within 5"), but the closest 3" stack is approx 15' away along the side of a different wall. I'd like to properly vent the 3 fixtures and was curious if I could tie the vents for those fixtures into one and punch it out the side of my exterior wall, above grade (similar to a sump pump discharge), and finish it off with a nice looking cover. Is this acceptable? Reason is that there is no space above this general area to run a new vent to the attic. It makes sense to me, just don't know if it's legal...
If it's not legal, then am I allowed an unlimited horizontal run of vent pipe to reach one of the existing stacks?
Thanks for the advice...
