I have new construction with 4" drain and 2x4 exterior walls. I am building a detached shop/living quarters with 2x4 walls and all plumbing is in one exterior wall.
- how would you run it? :)
- are cripples considered load bearing and does the 60% rule if doubled apply?
- can i go thru 3 cripples and then wrap around the king/jack studs? code says you can drill thru 2 on load bearing so question 2 is key. I could cut the window shorter and take bathtub vent straight up if needed I guess.
- if tying in vent lines on the horizontal how much angle required? just thought of this - can probably lookup myself.
