In plumbing terminology, what does the acronym DWV stand for?

Explanation:
DWV stands for Drain, Waste, Vent. This naming points to the part of a plumbing system that handles removing used water and waste from fixtures while also venting sewer gases to the outdoors. The Drain portion moves liquids away from each fixture, the Waste portion carries solids and other waste, and the Vent portion provides an opening to the atmosphere to balance pressure and allow gases to escape. This system is separate from water-supply lines, which is why options that include Water or a Valve don’t fit. The standard phrase uses Drain, Waste, Vent.
