    I want to re-route my 3" ABS vertical main stack through a wall in the 2nd story bathroom. I want to use a double wye tee. One 45 to be toilet drain, the other 45 to offset the stack to continue through the roof. The center 3" opening would be capped. [See diagram] This is to avoid cutting a floor joist. Is this a workable solution?
