1.5–2-Inch PVC Air Admittance Valve for Secondary DWV Venting, 20 DFU, Single or Two-Pack - Oatey 39016
1.5–2-Inch PVC Air Admittance Valve for Secondary DWV Venting, 20 DFU, Single or Two-Pack - Oatey 39016
An air admittance valve opens when negative pressure develops in a drainage system, allowing air into the piping, then closes at zero or positive pressure to help contain sewer gas. Oatey Sure-Vent model 39016 is designed as a secondary vent for compatible drain-waste-vent systems using a 1.5-to-2-inch straight Schedule 40 PVC adapter.
Choose one valve or a two-pack. The source identifies a 20-DFU retail rating for DWV piping 2 inches and smaller, while the included-component text separately lists 160 branch and 24 stack DFU capacity; system design and code determine the applicable rating. The valve is also described as approved for vent pipe up to 3 inches and compliant with ASSE 1050 and 1051. Install only where local code allows, keep it accessible and upright, and have a qualified plumber confirm sizing, placement and solvent-weld connection.
