Hi all,
I want to install a utility sink in my basement by tying it into the existing 3" vertical drain pipe that comes from the second floor washroom. There is currently a clean-out located 13" up from the basement floor. My plan was to put in a 3"x3"x1.5" sanitary tee below the clean-out and orient it such that the 1.5" connection point on the tee would be facing outwards rather than to the side. I'd connect an elbow there and run the 1.5" branch line from the sink to the sanitary tee on the outside of the wall to avoid having to cut open the wall and cut studs. The sink will about 3' away from the current drain. So here are my questions:
1. should the tee be above or below the clean-out or does it matter?
2. is it ok to orient the tee the way described and run the 1.5" drain line from the sink on the outside of the wall?
3. any venting concerns? My house is 13 years old so I can only assume that this drain stack is tied into the primary vent stack at some point above.
I've done some plumbing in the past - installed and replaced sinks and toilets, moving hot water tanks, completed all PVC plumbing for an above ground swimming pool - so I'm not a complete newbie. I may very well engage a pro to do this for me but I'm curious at this point to know if this is a major piece of work for a DIY'er with some experience or if this should be a relatively straight forward job.
Appreciate any input on this.
Thanks everyone!
