Johnson Tee Setup with Window

[Robert McNeil]

I have been reading through the threads on Johnson Tees. I was not aware of them until recently. I attached a picture of my current drain setup. I have a window above where the sink will be and the top of the sil framing is at 41-1/4” from the subfloor. The dishwasher will be to the left of the sink. I have seen suggestions that the cleanout be between the two tees when installing the double fixture fitting. However, where it stands now the dishwasher would cover a cleanout. I am wondering what my options are for making a johnson tee work. Thanks all.

You can place the clean out through the outside wall.

Would it be ok to move the waste drain and double tee over to the left since I have a crawl space below. And angle up and to the right with the vent. That way I could keep the cleanout on the inside and put it in the cabinet to the left of the dishwasher.

Never plumbed a Johnson tee but if you want one the way I see is remove santee put a double fixture santee the stud to left of your 2 inch stack leave alone but the second stud move to allow a ptrap in the bay then run stand pipe to correct height .
