This diagram represents a residential DWV (Drain-Waste-Vent) system. In plumbing, there are two distinct flows happening simultaneously in these pipes: 1. Gravity (Waste/Water): Flows down to the sewer. 2. Air (Venting): Flows up to the roof to balance pressure and allow the water to move smoothly without gurgling or stopping. 1.
