OATEY 39012 – Frequently Asked Questions

1) Will the Oatey 39012 air admittance vent thread onto 1-1/2 inch pipe?
The 39012 is a 1-1/2 inch NPT connection, so it threads onto a 1-1/2 inch male NPT adapter. On a solvent weld ABS or PVC drain arm you add a threaded adapter at the stub to take it. It will not solvent weld directly.
2) How many fixtures can one Oatey 39012 in-line vent handle?
It carries a DFU rating of 20 on a branch and 8 on a stack. That covers a typical sink, tub or shower group, but size the branch load before you rely on a single unit for a multi-fixture run.
3) Can I use an in-line air admittance vent instead of running a vent through the roof?
An in-line vent like the Oatey 39012 admits air when the drain pulls negative pressure and seals shut under positive pressure, so sewer gas stays in the line. That lets you vent a sink, tub or shower where running a pipe to the roof is impractical, such as an island sink or a remodel with no chase. Local plumbing code decides whether it can substitute for a through-roof vent, and the system still needs a main stack vent.
4) Is the Oatey 39012 approved for use in an RV or trailer?
Yes. The 39012 carries an NSF-24 listing for use in recreational vehicles, which is the standard that covers plumbing components in RVs.
5) Is the Oatey 39012 vent ABS or PVC, and does that matter for my drain line?
The body is ABS in black. Since it connects by 1-1/2 inch NPT threads rather than solvent cement, it works on either an ABS or a PVC drain as long as the threaded adapter at the stub matches your pipe material.
6) Does this Oatey air admittance vent have to be installed upright?
Yes. It is a spring-loaded, gravity-assisted valve, so it mounts vertically with the vent cap up. Mounting it on its side or inverted will keep the seal from seating properly against positive pressure.
