DWV closet flanges are PVC plumbing fittings used as the connection point between a toilet drain and the DWV piping system. DWV closet flanges securely attach toilets to the floor and connect them to the building’s sewer drainage system for a reliable installation. DWV closet flanges are made to fit over or inside the Features and Benefits
DWV sewer pipe. They include a mounting surface that sits flush with the floor and include bolt holes for completing hookups. The flange provides a tight seal to prevent leaks and the release of odors. They are used to maintain hygiene and functionality in bathroom installations by preventing sewer gasses from entering the building and ensuring wastewater is properly directed into the sewer drainage system.
Available DWV toilet flange types include closet flanges with a ring, one piece closet flanges, and reducing closet flanges. Reducing closet flanges fit over 3" pipes while connecting to a 4” toilet. DWV flanges are a standard 4” in size to match common toilet drain hookup sizes.

Applications and Uses
PVC DWV closet flanges are found in virtually any plumbing system with toilets. They are used extensively in homes, apartments, and other residential dwellings as well as restrooms in offices, restaurants, schools, and other commercial spaces. DWV closet flanges are used in new constructions, renovations, and repair projects to properly mount and connect toilets. They work by creating a sealed connection between a toilet's outlet and the drainage pipe that leads to a sewer or septic tank. They are often installed over or inside the drainpipe and then bolted to the floor for stability. A wax ring or similar sealant is often placed between the toilet and the flange to ensure leak prevention. Once installed, they allow wastewater from the toilet to flow into the sewage system for sanitary and efficient waste disposal.
