Andy asks:
I have built a room in the attic space and would like to add a sink and a urinal to it.....
Is it acceptable to connect the drain line by "T"ing into the vent stack from a bathroom below ??. It would only be liquid waste and low flow.
The area I live in does not require inspections or permits, but I'd like to do it in the proper manner if possible.
Any advice on this from informed sources would be appreciated...
