OATEY 39220 Air Admittance Valve for plumbing

This OATEY 39220 Air Admittance Valve serves plumbing systems requiring venting without a traditional roof penetration. It accepts an inlet size of 2 in to 3 in using the included adapter and handles up to 160 DFU. The body material is PVC. It is not intended for buyers who need a higher pressure rating than 0.01 psi or a different DFU capacity.

Thermals noise and power draw in normal use

This valve operates passively with no moving parts, so it produces no noise and draws no power. Thermal performance is not a factor for this component. Installers who require active mechanical ventilation or powered venting should note that this device provides neither.

Highlights

  • Handles 160 DFU for high-capacity venting

Questions about this item

How do I fit the supplied adapter onto the 2 in to 3 in inlet of the Oatey 39220 Air Admittance Valve?

Slide the adapter onto the valve inlet, apply PVC solvent cement to both surfaces, push fully home and hold until the joint sets; the step most people rush is allowing enough cure time before testing the system.

What ongoing maintenance does the 160 DFU Air Admittance Valve require after installation?

The valve is designed to operate without routine servicing; if the internal membrane ever fails to seal under the rated 0.01 psi pressure, the entire unit is replaced rather than repaired.
