I would like the p trap to be in the wall instead of outside. I dont have enough space to place a dryer next to the washer with the exterior p trap.

I currently have 1 1/2" pipe for the drain and p trap and I was told 2" is required? I'm in california.

My issue is that there is not enough space in the wall. The drain pipe is attached to a 3" vent pipe that occupies most of the space.

I was hoping to remove the existing 1 1/2" drain and attach directly to the 3" vent pipe. Will that work. I attached pictures that are obviously not to scale but I hope you can understand them.
