@mgplumbinginc: A 1st floor full bath that consists of a Sink, toilet and a Tub/Shower combo unit. 1 wet vent takes care of this entire bathroom group. A bathroom group is 5DFUs Simple enough. I always arm over to a sink so I don't interfere with the electrical box for the light fixture above center of sink. It's easier to drill across studs in a wall than drilling below in joists and screw the tinner. #teamwork #plumber #dayinthelife #bluecollar
