Air Admittance Valves (AAVs) are plumbing devices that allow air to enter a drainage system when negative pressure occurs, helping maintain proper system pressure while preventing sewer gases from entering the building.
Are Oatey air admittance valves code-compliant?
Yes, Oatey Sure-Vent Air Admittance Valves comply with ASSE Standards 1050 and 1051 and are IAPMO listed, making them acceptable under many plumbing codes when installed in accordance with local regulations and manufacturer instructions.
What are the benefits of using an AAV over a traditional vent?
AAVs simplify installation, reduce roof penetrations, and are ideal for remodels or locations where venting through the roof is not feasible.
Air Admittance Valves open automatically to admit air into the drainage system when wastewater flows and negative pressure develops, equalizing pressure and supporting proper drainage. When not in use, the valve closes to block sewer gases from escaping into occupied spaces.
