OATEY 39223 Air Admittance Valve
The OATEY 39223 air admittance valve provides venting for plumbing systems without a traditional roof penetration. It accepts a 3 in to 4 in inlet connection and is rated for 500 DFU capacity. The body is constructed from PVC material. This valve suits installers needing code-compliant venting in confined spaces.
Sustained-load behavior
Under continuous drainage demand the valve operates at a maximum pressure of .01 psi. The 5 1/4 in vent height allows consistent airflow relief during prolonged fixture use. The PVC body resists corrosion from sewer gases over extended service periods. No external power or mechanical assistance is required for operation.

Questions about this item
How much heat or noise does the 39223 valve generate when it operates continuously?
The valve is a passive plumbing component with no moving parts, so it produces no heat and no audible noise during all-day operation.
What existing pipework must I already have for the 39223 valve to fit and function?
You need a 3-inch or 4-inch PVC drain line and a vent stack that can accommodate the 5 1/4-inch vent height of the valve body.
