Oatey® Sure-Vent® Air Admittance Valves (AAVs) provide a reliable, space-saving solution for ventilation in plumbing systems, eliminating the need for costly and complex vent piping installations. Designed to open under negative pressure, these valves allow air to enter the drainage system to equalize pressure, effectively preventing the siphoning of trap seals and blocking the escape of sewer gases.
Each Sure-Vent AAV is manufactured with precision to meet ASSE Standards 1050 and 1051, and all sizes are IAPMO listed for assured quality. Available in four sizes, from 8 Stack/20 Branch DFU to 160 Branch/500 Stack DFU, Oatey Sure-Vent AAVs suit a range of residential and commercial needs, offering efficiency, durability, and compliance across various applications.
