Hi all,
I have a plumbing scenario I need help with. Trying to confirm what code allows for and what is best. for my side split house I have a 2pc powder room (currently under reno) on main level and 3pc bath upstairs (being added). I'm tying a stack into the the existing 3" line that comes up from the basement for the powder room. How can I do it? with a long sweep? or do I have to dig the drain down lower and drill a new hole through the concrete to accommodate a tee?
The 3" stack will run straight up through the roof. The 3pc upstairs washroom will drain down it. So I'll use the wet stack to vent the 2pc bath. and for the 3pc upstairs venting I will connect venting lines to it in attic before it exits the roof. The only part I haven't figured out is how I'm allowed to make the drain connection. I live in Ontario Canada.
If option B is the required choice - do I have to also use a long sweep turn through the concrete wall?
refer to the drawing attached, I can send pics as well if it helps.
Thanks!
