Marketing InformationAvailable in models with a variety of different patterns and installation options, Water-Tite® closet flanges are a great choice for efficient and secure toilet installations. These durable plastic toilet flanges sit flush with the floor, allowing installers to quickly and easily connect water closet outlets to plumbing systems. Choose from standard or long pattern models (with or without knockouts or pipe stops) to fit either ABS or PVC piping. Intended for solvent-weld installations only, these closet flanges fit SCH 40 DWV (drain, waste and vent) pipe in 3, 4 in or both sizes.
