One reason is that there is more room to cross a 1 1/2" vent with a water line than there is with a 2" one. : : Does the two inch limitation apply to vents as well? i.e., is it OK for the shower vent to be 1-1/2" where it comes up vertically out of the cement at a stud wall. : : I often wonder why some folks bother to use 11/2 vent if they already are running a 2" waste line why not just continue with 2" : : Unless space is a consideration why not just run everything the same size rather then trying to save a few cents. : Yes an 11/2 Vent is legal in most codes but 2" would be the way I would go.
