The only thing that I find questionable is the section in the green circle. The 2 fixtures are not both draining in the same vertical continuous waste and vent.
That's the way I interpret the code anyway
The code clause you quoted is referring to a system where you have to wet vented fixtures draining into a vertical soil or waste stack, or branch, or w/e and they are connected at the SAME vertical elevation you must connect them with a double fitting.
There is only one vertical portion of piping that is wet vented and that's from the sink.
Krow not to be argumentative but how would you wet vent a bathroom group in a basement then?
inspection passed today as a wc,lav,and bath tub wet vent, shower dry vented at a 45 degree angle as discussed previously thanks again mr doherty.
