Hello,

I've noticed this photo used in conversations concerning laundry room plumbing and was my original plan. However, for reasons I can go into later, I need the clothes washer "downstream" of the utility sink. Would you simply run a horizontal branch below the standpipe p-trap, and take the washer trap arm to a san-tee, and down to this horizontal branch?

Yes. First fitting would be a san tee low horizontally to your sink location. Atop that san tee and high enough that the bottom of the trap clears over the top of the sink drain.

Utah use IPC 2015.

Is that sink a laundry sink that is right next to the standpipe? If so, there is ones solution:
http://media.iccsafe.org/news/icc-enews/2018v15n13/2018SC-IPC802.pdf describes a standpipe trap shared with a laundry tub. As I read it, the 2018 change was to allow it in apartments, and this was available for houses in earlier versions.

index.php


If not, under IPC, once other waste joins the laundry standpipe, officially the pipe size should increase from 2 to 3 inch. You may be able to get a pass on that for existing available drain.

Unfortunately in the UPC, should have started with that. So, I'm pretty sure I can't use the above solution? Thanks for the quick replies.

But with UPC you can run both traps into the 2 inch drain line without a variance, so good.
