DIY'er just moved into mid-Michigan ranch built in 1971. 1st floor laundry drains through 2-inch pvc pipe to under the utility sink in basement. Need to move the pipe running down the wall into a to-be-built 2x4 stud wall going in behind the sink.

Any suggestions on what I should consider regarding running the pipe inside the new all or observations/corrections based on these pics?

Thank you all! The site is very helpful

The sink drain for sure and maybe the laundry drain both need venting.

Thanks. I checked based on your comment. The laundry pipe is vented. Wouldn't that vent support both sink and laundry?

Unless local code states otherwise, you can't wet vent(utility sink) from a fixture on a different floor level. The utility sink could use an AAV if allowed or run the sink vent up and connect it to the laundry vent pipe, at least 6" above the top of the standpipe.

Thank you! Glad I checked before I started framing walls. I'll get a plumber for venting, moving the sink to the left a foot or two and routing the laundry drainpipe down through the proposed new wall that will go up against the basement block wall behind the utility sink.
