C5851A43 4 In. x 3 In. ABS Reducing Adjustable Closet Flange with Plastic Coated Steel Flange (Hub). DWV is used for non pressurized sanitary system Drain, Waste, and Vent. There are two types of DWV plastic: ABS (black plastic) and PVC (white plastic). The sanitary drainage and vent piping systems are installed to remove waste water and water-borne wastes from the plumbing fixtures and appliances. DWV also provides a circulation of air within the drainage piping. ABS (black) and PVC (white) plastic pipe and fittings have identical uses. The only reason for selecting one material over another is either the cost of the material or local plumbing code restrictions.
