I'm not sure if I don't get what you're saying or you aren't understanding my drawings (hard to believe as impressive as they are)

This is the old toilet (left), new toilet (right) and path of waste pipe (brown) that needs to go through the 4x6 beam (yellow).




There's a vent out of the roof near the existing toilet. The plumber (we had someone come out to discuss the feasibility and rough estimate) said that he would put a vent in near the new toilet. It was special. I think it may have been an "air admitance valve"
