|In response to Re: How do I get 3" drain past floor joist?|
You van cut a 3.5" hole in a 2x8" joist, but you need to reinforce the joist by both sistering and adding double blocking. Pay strict attention to adequate nailing, and you can even use steel reinforcements (made by Simpson Strong-Tie) in the area that you will have to cut out.
: : Is there any engineering solution? I would be willing to add floor joists, although these new joists would have to have a hole drilled through them also.
