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.\u003c\/p\u003e\u003cp\u003eChoose 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.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: Oatey\u003c\/li\u003e\n\u003cli\u003eProduct: Air admittance valve\u003c\/li\u003e\n\u003cli\u003eSeries: Sure-Vent\u003c\/li\u003e\n\u003cli\u003eModel: 39016\u003c\/li\u003e\n\u003cli\u003ePack options: 1 or 2 valves\u003c\/li\u003e\n\u003cli\u003eConnection range: 1.5 to 2 inches\u003c\/li\u003e\n\u003cli\u003eAdapter: Straight Schedule 40 PVC\u003c\/li\u003e\n\u003cli\u003eMaterial: PVC\u003c\/li\u003e\n\u003cli\u003eValve type: One-way air valve\u003c\/li\u003e\n\u003cli\u003eUse: Secondary DWV vent\u003c\/li\u003e\n\u003cli\u003eRetail rating: 20 DFU for DWV 2 inches and smaller\u003c\/li\u003e\n\u003cli\u003eIncluded-text rating: 160 branch \/ 24 stack DFU\u003c\/li\u003e\n\u003cli\u003eVent pipe approval: Up to 3 inches as stated\u003c\/li\u003e\n\u003cli\u003eStandards: ASSE 1050 and ASSE 1051\u003c\/li\u003e\n\u003cli\u003eDimensions: 2.9 x 2.9 x 5.2 inches\u003c\/li\u003e\n\u003cli\u003eDocumented weight: 4.8 oz\u003c\/li\u003e\n\u003cli\u003eInstallation: Must follow local plumbing code\u003c\/li\u003e\n\u003c\/ul\u003e\u003csection class=\"product-faq\"\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eWhat does the Oatey air admittance valve do?\u003c\/h3\u003e\n\u003cp\u003eIt opens to admit air under negative drain pressure and closes at zero or positive pressure to help contain sewer gas.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eWhich connection sizes fit model 39016?\u003c\/h3\u003e\n\u003cp\u003eThe included straight PVC adapter is listed for 1.5-to-2-inch connections.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eHow many valves can I order?\u003c\/h3\u003e\n\u003cp\u003eChoose the single-valve option or a two-pack.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"qa\"\u003e\n\u003ch3\u003eCan this valve be installed anywhere instead of an open vent?\u003c\/h3\u003e\n\u003cp\u003eNo. Placement and use depend on local plumbing code and DWV design so a qualified plumber should confirm the installation.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"My Store","offers":[{"title":"1.5-2\" (Pack of 2)","offer_id":64470981935473,"sku":"B0HG3LDXJ3","price":73.98,"currency_code":"USD","in_stock":true},{"title":"1.5-2\"","offer_id":64470981968241,"sku":"B000BVMX62","price":46.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/7064\/0241\/files\/615_l3xrRPL._AC_SL1500.jpg?v=1787907637","url":"https:\/\/allkindora.shop\/products\/oatey-air-admittance-valve-1-1-2in-2in-20dfu-39016-1-each","provider":"All Kindora","version":"1.0","type":"link"}
