Oatey 39239 Installation Kit with Tubular Adapter Air Admittance Valve

The Oatey Sure-Vent 6 DFU Capacity Air Admittance Valve is a one-way valve specifically designed to allow air to enter the plumbing drainage system in instances where negative pressures occur within the piping system. This serves the crucial purpose of preventing sewer gases from escaping into a building without the need for a vent pipe that extends to the open air.

The main function of the Air Admittance Valve is to offer a convenient method for air to enter the plumbing drainage system, effectively closing by gravity and sealing the vent terminal when there is zero differential pressure or under positive internal pressures. Oatey products, including the Sure-Vent air admittance valve, are widely used in both residential and commercial settings and have established a reputation for quality among consumers.

The Sure-Vent air admittance valve installation pack is a comprehensive solution that can be used as an alternative to a secondary vent in a DWV system. It is designed to vent up to 20 DFU Branch or 8 DFU Stack and includes essential components such as the AAV, P-trap, 6-inch extension tube, PVC threaded adapter, and deep box flange. This versatile pack is approved to handle vent pipes of up to 2 inches in size.

The air admittance valve opens and closes as required by the building's plumbing system and includes a protective sleeve to facilitate installation and keep the valve free from debris. Additionally, all Oatey products, including the Sure-Vent air admittance valve, undergo rigorous testing to ensure trouble-free performance, complying with standards such as ASSE Standard 1050 and 1051, as well as being approved by the International Plumbing Code (IPC) and Uniform Plumbing Code (UPC).
