I am looking at connecting a laundry stand pipe and utility sink to my main sewer line and need some help on determining the proper method of going about that. I was hoping that a double wye would be acceptable but after reading through numerous post, I am not entirely sure.
I have attached a photo of the soon to be laundry room, in it you can see the laundry stand pipe to the left and the utility sink to the right. Both will be connected to a 1.5" vent that runs up to the attic before tying back into the 4" main stack as it goes through the roof. The 4" stack in the middle of the picture is what I am trying to connect the laundry room to, this line has the first floor toilet, tub, bath sink and kitchen sink all tied to it. I don't know if it matters but I should also mention further down the line I also have a basement bath attached to this line (shower, bath, sink) these are all attached to that 1.5" vent line as well. The state I am in is Wisconsin.
Questions
Is it acceptable to use a double wye in this situation? or a double tee?
I have thought about stacking wyes or tee but it will put the drain to high for the utility sink or make the drop from the stand box to the p-trap right a little bit less than the required 18" minimum.
Any help would be greatly appreciated and thank you in advance.
