Hi Guys. New to this forum. Joined to ask a question about my current bathroom remodel.
I am a licensed Civil PE, but work primarily in the oversight of heavy highway construction. I am an advanced DIYer at my house and have/can do just about anything.
I am redoing my master math and all the plumbing needed to be relocated. The other side of the wall shown is the hall bathroom and the 1-1/2" PVC originally drained that sink only. During the remodel of the master bath, coincidentally, the left dual vanity sink almost fell in line with the sink behind it. Originally, I was going to run an independent arm to the copper stack, but last minute decided to cut into the existing drain for the other bathroom's sink and tie in as shown. (In the photo, the 90* is obviously not installed, just twisted up to avoid being hit). My thought process for doing this was to avoid cutting up the copper stack.
Now the issue!! Since the day I cut into the 1-1/2" PVC, the functioning sink in the hall bath has had a sewer smell. Conceptually, I can't wrap my head around how this could be happening so I am here to ask for advice.
Hoping someone can point me in the right direction before I go cutting a hole in my almost finished bathroom wall. Some photos of the plumbing and general bathroom work attached. Thanks!
