In my unfinished basement with 3-piece rough-in, I assume the pipe that goes all the way up serves as the vent for the other two pipes (for tub and toilet). If a vanity sink drains through this vent pipe, will it block the vent to the tub and toilt pipe? If I also install a wet bar in the basement, can I also use this vent pipe to drain without adding any new vent? Thanks!
