OK, I reviewed what you posted. 2.5.2.1(d) refers to the wet vent section only, and does not apply to the drain downstream of the wet vent section. Also, subsection (f) limits the hydraulic load of separately vented fixtures draining through the wet vent to 2 fixture units, so what is the hydraulic load for your laundry standpipe? The code I am under assigns 3 DFUs to a laundry standpipe, in which case the standpipe would be required to come in after the WC. In any event, it will be better to move it to after the WC.I posted the wet venting rules from the Canadian code earlier in the thread along with the diagram showing the kitchen sink coming in upstream of the WC. It says under the wet venting rules that "water closets are installed downstream of all other fixtures". The way it reads makes it seem to me that this applies even in the case of the separately vented washer. There are a few other examples provided, but none of them have anything come in downstream of the WC.
