Hi, I'm adding a laundry sink to a washer drain, and want to make sure I do it properly and vent it properly. The new sink will have a P-trap under it and come in from the left in the picture. Is it acceptable to tie in a new TEE above the existing TEE where the washer drain ties in? I believe the washer drain is 2" and the vent pipe above the existing TEE is 1.5". If this is not acceptable, what is the proper way to do this? Thank you in advance!
