PVC DWV Fittings
DWV is an abbreviation for Drain/Waste/Vent, which indicates that these fittings are intended for typical sewer drainage and venting applications. DWV fittings are very common and are accepted by code practically everywhere. They are installed in combination with Schedule 40 PVC pipe using solvent cement and primer. PVC DWV fittings are designed for no-pressure, gravity-flow applications only, but can handle up to 25 psi for the purposes of air pressure testing.
