OATEY 39225 – Frequently Asked Questions

1) Will the Oatey 39225 Sure-Vent air admittance valve fit 1-1/2 inch pipe, and can it be used on 2 inch vent pipe?
The 39225 comes with a 1.5 in. white tubular adapter and a 1.5 in. connection size, so it lands directly on 1-1/2 inch tubular. The valve head itself is one size approved to handle up to 2 inch vent pipe, so the same AAV covers both runs as long as you use the right adapter for the pipe you are tying into.
2) How many fixtures can the Oatey 39225 Sure-Vent handle?
It is rated 20 DFU on a branch and 8 DFU on a stack. That covers a typical island sink, a lav, or a small group of fixtures on a branch line. If you are venting a whole stack serving more than 8 drainage fixture units, this one is undersized and you need a higher-capacity AAV.
3) Can an air admittance valve replace the main vent through the roof?
No. The Sure-Vent 39225 is for use as a secondary vent only. Every drainage system still needs its primary vent open to atmosphere; the AAV handles individual fixtures or branches where running a vent through the roof is impractical, like an island sink or a remodeled bath.
4) Is the Oatey Sure-Vent 39225 code approved for IPC and UPC jurisdictions?
It is approved under both the International Plumbing Code and the Uniform Plumbing Code, and it complies with ASSE Standard 1050 and 1051. Local amendments still govern where AAVs are permitted, but the product carries the listings inspectors normally ask for.
5) At what pressure does the Sure-Vent valve open, and does it let sewer gas back out?
Sweet Spot technology opens the valve at -0.01 psi and seals at 0 psi and above, so it admits air the instant a fixture discharges and closes as soon as pressure equalizes. Every unit is functionally tested at 1/4 inch H2O and 30 inch H2O. Screening on the air inlets guards the seal against debris.
6) What material is the Oatey 39225 air admittance valve and its adapter?
Both the valve body and the tubular adapter are PVC, finished white so it blends with standard white tubular drain work under a sink. Unit weight is about 0.5 lb.
7) What is the protective sleeve on the Oatey Sure-Vent for, and should I leave it on?
The sleeve gives you something to grip while you thread the valve onto the adapter, and it keeps drywall dust and debris out of the valve during construction. Leave it in place after install; it stays on in service to keep the valve clean.
