DWV stands for drain waste vent and it refers to a specific type of PVC pipe and fittings designed for non-pressurized applications like venting and drainage for sanitation. DWV fittings are generally less expensive than standard pressurized schedule 40 PVC pipe, though it is similar in appearance.

DWV fittings are white in color and are made of PVC, but they are different from standard PVC fittings in design. DWV fittings generally come in larger sizes than standard schedule 40 PVC fittings and use hub connection ends in addition to standard male pipe thread, female pipe thread, etc. The smaller sized fittings are made by molding, while larger and less common fittings are fabricated from the same white PVC material.

Drain waste vent fittings are recommended for temperatures up to 140 degrees Fahrenheit. Our fittings are made to ASTM standards for DWV and are NSF 14 certified. DWV is used mostly for drainage or venting sewage. You may have seen DWV fittings coming out the ground around large buildings. Those fittings are called cleanout fittings.
