I'm remodeling a bathroom which had a single sink, and I'm going to a double. Problem is I cannot run the drain over from the second sink to the existing trap because of drawers in the vanity. I also cannot go in the wall and over because of other pipes.
I can tie into the bathroom vent above, creating a wet vent, and run that down to the basement; then connecting into the main waste stack. The drop from the p-trap to where it ends in the photo is about 9 feet (its a multi-level home).
If I can do this, is it best to use a wye or tee into the main? I was going to position the tee/wye on the main stack pointing up, then run over to the new drain/vent using 45's. I also have two places where I can connect to the main (is there a better place?). Below is a photo; thank you for your advice.
