EDITED*** initial post updated and irrelevant plan removed... If that's a no-no please let me know! Just trying to keep the post relevant to anyone reading now or in the future.
Per the previous, I am attempting to install a laundry sink next to my washing machine and still keep the standpipe. I confirmed that as of today we use 2020 MPC here after talking with the inspector and verifying on the DLI website. Seems to be based upon UPC based upon the foreword. After a chat with the inspector a new plan was drawn up that should meet code. Just a couple issues that I was hoping for seasoned opinions on.
First, the existing load bearing wall. Code allows me to bore 40-60% if studs are doubled with no more than two successive doubled studs. Technically it can be done to code for my purpose, but I don't love boring 2" drains and 1.5" vents through two studs, basically killing the bearing capacity of 1/3 of the wall. While I doubt anything will collapse, I don't really want anything cosmetic to pop up in the bathroom above (drywall/tile cracks, soggy floor, etc). I have lumber, time, and an extra 3.5" of space and was considering just framing in a non-bearing 2x4 partition wall in front of the existing bearing wall to run utilities, which I could then run unencumbered through 3 stud bays. You guys see this stuff everyday and me... not so much. This seem like cheap insurance or am I being anal and creating extra work where none is necessary? I do tend to over-engineer anything I build because I am not a SE.
Second, per the plan below. When it comes to the two tees referenced (one from the main vent stack to auxiliary vent, and then from the new 2" tub drain to the 1.5" vertical auxiliary vent), should I just use regular DWV tees here? I tried finding them locally and can only find sanitary tees to varying degrees. I found that odd and then second guessed if I was hunting for the right fittings. Just trying to make sure I put in fittings with the right sweep.
Any other input or advice on the below would be appreciated before I tear into this. Thanks again!
