Laundry Sink Addition & Max Sink Drain Rough-in

[chaschl]

I am moving my washer leftward to stack appliances and maximize space. My research findings tell me that the max height for a sink rough-in is 16-in. My current situation will either give me a drain rough in at approximately 25-in or I would have to remove a framed wall and chip out concrete to replace so much more hardware.

I have found a 16” standard height and a range of 14 -20” height. In my situation, the lowest I can hope to install in in existing pipe is 25”.

I attached my solution drawing and photo of the existing drainage system.

Thank you for helping me solve this problem

You could put the laundry tee where the cleanout is, the utility sink tee right above the that, and the cleanout above that.

number of ways to do it cut that mess out is one way . another way use the clean out which is a 2 inch santee put a wye in for a cleanout and add a aav under the new sink assuming az allows aav instead of real vents

AZ code permits air admittance valves, but there is not enough pipe to cut the existing for new connectors. Is there a way to loosen the pipe adhesive? Otherwise, I would have to break into the concrete.

I’m trying to avoid breaking out the concrete to change the DWV pipes. If I could remove current connections this would be an easier job

Does my concept drawing work? Or is it a bad plan?

just use the clean out for the sink
