I started to rough-in my laundry drain box, not thinking to check the 2018 IRC. I was using information that I had from 14+ years ago (see attached).
Based on my p-trap at 12" above the floor, at what elevation do I need to mount the bottom of the drain box? Based on 2018 IRC, it would seem I need to be at 42" above the floor. If so, luckily I have only dry fitted the box to the standpipe.
Any help clarifying this would be greatly appreciated.
