Sink vent pipe

In modern plumbing, a drain-waste- vent (or DWV) is part of a system that removes sewage and greywater from a building, and regulates air pressure in the waste-system pipes to aid free flow. Waste is produced at fixtures such as toilets, sinks , and showers, and exits. Vents generally rise from each fixture to join a main vent stack that extends through the roof. Install the vent between the sink P-trap and the point where the waste line leading from the trap drops to the main sewer. All traps need venting in all cases.
