Is it acceptable to run a 2 foot T from a vent pipe to my single bathroom sink drain? I have a 1 1/2" vent pipe in the wall about 2 feet from my sink. I have double wall below the countertop but single wall above it so I can't run any venting above sink. The vertical vent pipe is in a double wall in the shower next to the sink. I would like to just run a sloped ABS section from the vertical vent to the middle of the area below sink and attach my sink p trap there. What do you think? Thanks.
