The peninsula sink piping detail shows a sink connected to a 3-inch sanitary stack via a vent stack routing through the nearest partition. The fixture vent rises inside the cabinet as high as possible toward the drainboard, maintaining dimension X at a minimum of 6 inches above the bottom of the fixture. A cleanout is provided for the vent, with horizontal runs sloped downward toward the stack. The vent stack extends upward through the roof as a vent through roof penetration.
