Tying into 4” Vertical Drain

[VTMike24]

Looking for feedback on my plan to tie a 2” drain for a washer/sink into my existing 4” drain.

I am thinking about adding a 4x2” sanitary tee just above the slab, then adding a 4” wye back in above the tee. This would allow me to keep the p trap for the washer between 6-18” off the ground. If I cut off the current wye, there would be about 2” of stub above the slab.

The washer will be located just around the corner from the main drain (on the right in the picture).

Thoughts?

Just make sure you are venting the new sink to prevent siphoning of the p-trap.

Thanks, Terry. I will be.
