Hi, I have a question that would seem to have an obvious answer but I am having trouble finding it.
I'm installing a new bathroom vanity in our downstairs half bath which is taller than the old one. This is the model:

The problem is that the fixed bottom of the upper cabinet is exactly in line with where the waste line goes into the wall. I could cut away some of that bottom to make room, and that's a backup plan, but I don't like the idea of the P-trap hanging out in the open like that. Granted, most people wouldn't notice it, but I'LL KNOW IT'S THERE. You get me.
So, I'm thinking about cutting into the wall and moving the sanitary tee upward maybe 6 inches. It's got a typical vent pipe up/waste pipe down from there. My questions are three:
1. There's an upstairs bath pretty much right above, both installed by the builder 25 years ago when the house was built. My guess is that the vent is used as a waste pipe for the bath above, but I can't find anything specific that says whether or not that's allowed. Is it? Are there any gotchas I need to know?
2. I was trying to figure out how to attach the new tee into the line. Since vent and waste pipes cannot be moved, my best guess of how to splice it in is to cement the tee normally on the top and use a no-hub or flexible coupling on the drain side of the tee. Like this:
Is that the way to go? And should it be a no-hub or flexible coupling?
3. I know I can use a short hacksaw to cut the pipe in the wall. But I just bought one of those nifty oscillating tools and it seems like that might be just the tool for the job. Thoughts?
Thanks!
