Hi I just framed out my laundry room in my basement and I'm looking to run add a utility sink and I need to add a drain line for both the washer and the utility sink though the utility sink is going to be the left of the washer so I'm not sure how I would branch off a drain from the washer drain. Here is a picture to make things a little easier to explain.
The utility sink is going to be to the far left and originally there was just a trap coming off of where the main drain line which I cut.
If I was having the utility sink before the washer near the main drain this wouldn't be an issue but since I need to run a trap for the washer how then do I branch off of that to run the line for the utility sink? Thanks
