It fits 1.5" to 2" PVC Sch. 40 pipes and vents up to 160 DFU branch or 24 DFU stack, ensuring efficient drainage and preventing sewer gas escape. Tested rigorously at multiple pressure levels and compliant with major plumbing codes, it offers a reliable, easy-to-install upgrade trusted by pros for over a century. ## Description Product Description Eliminate the need for a branch vent with the Oatey Sure-Vent Air Admittance Valve. This air admittance valve (AAV) provides the ideal venting solution for island sinks, remote bathroom groups, and remodel jobs by eliminating the need to be connected directly into the stack vent. This AAV keeps the sewer and atmospheric pressures equalized, allowing water to drain freely. Its one-way valve is designed to allow air to enter the plumbing drainage system when negative pressures develop without the use of a vent extended to open air and to prevent sewer gases from escaping into the building. The Oatey Sure-Vent AAV is sensitive to pressure changes to consistently open and close as needed by the plumbing system, closing by gravity and sealing the vent terminal at zero differential pressure (no flow conditions) and under positive internal pressures. This 1.5" x 2" PVC air admittance valve is approved to handle up to 3" vent pipe and has a 20 DFU (Drainage Fixture Unit) capacity. It complies to ASSE (American Society of Safety Engineers) Standard 1050 and 1051 for use a secondary vent.

From the Manufacturer Oatey Sure-Vent Air Admittance Valves provide the ideal venting solution for island sinks, remote bathrooms and remodel jobs by eliminating the need for a stack vent.

The bottom part of the vent is an adapter that allows solvent welding to 1.5" or 2" PVC (not ABS). So, for 1.5" ABS pipe with male threads, you need to use a 1.5 Female to 2.0 female adapter/coupler or, if no threads on the ABS, solvent weld on a 1.5" ABS to 2" female pipe thread adapter. **Q: Can I cut the vents coming through the roof and cap them in the attic with this?** A: Per code, you need one 3" vent out the roof. The others can be air admittance valves as long as there is access to replace them and they can get air to work properly. **Q: What is the difference between the 39016 and the 39017?** A: Just a different model number. They're both the same size for the same size pipe. **Q: i have 2 fixtures to the same drain, kitchen sink and sump pump, where should this Valve be placed? Both go to septic, Sink won't drain with pump on** A: First off I would highly recommend to not put sump pump discharge through your house waste system. It should always be run to the outside. One reason is that your system is not designed for the volume and another is that you are pushing sediment through it. It should be run to the outside away from the foundation or into a drywall system with your gutters if so eqiupt. If you do it the right way you don't need this valve. Also, what happened to your original vent? Lots of questions here....you should only need this for an island sink or difficult remodel situations. That said you can install this on a t above your trap arm or weir or somewhere above that ## Customer Reviews ### ⭐⭐⭐⭐⭐ Delivered on time, great produtc. *by A***L on April 10, 2026* Great product. work perfectly, solve a big problem in my project. delivered on time. thanks ### ⭐⭐⭐⭐⭐ All AAVs fail. Just replace it before you try anything else. *by M***E on February 23, 2026* I replaced my failed Sioux Chief turbo vent with this Oaty. Instant improvement. Most gurgling is gone. Drain is quiet. I only wish I had figured this out earlier before I tried everything else (thinking I had a clog or other issue). ### ⭐⭐⭐⭐⭐ You must be just what I needed... *by K***L on April 25, 2025* The plumbers who installed the original Studor vent also used pipe glue on the valve when they screwed it in. SIGH. Fortunately, when I purchased this as a replacement, the included hardware was exactly what I needed. If you need a valve like this, you know what it is. FUNCTION: Before installing it, I put it over my mouth and looked upward (it's meant to operate vertically). It would not allow air to flow outward, but would allow air inward exactly as desired. The flap inside seems to be higher quality than the original Studor I replaced. INSTALLATION: Very simple. Because of my unique previous install issue with the glue, I cut the existing pipe as close to the top as possible -- cutting off the previous screw-in ring. This included adapter has two levels of inlet rings: 1-1/2 and 2", depending on which pipe you have. They're two separate tapers on the same adapter. I've seen reviews where people seem confused that the smaller ring inside is actually what they need on the same pipe. I hand-tightened the vent and then glued the adapter back to the top if my (now bare) pipe. All of the old symptoms of a failing value went away. Inspecting the old valve (I wasn't about to put my mouth on it), I could tell that it wasn't completely closing anymore. Some dirt or residue was inside it and lightly just blocked the path. 7 year life span on the old one and now a 5-minute replacement next time due to the lack of glue on the threads hah. ## Frequently Bought Together - Oatey Sure-Vent 1-1/2 in.–2 in. 160 Branch, 24 Stack DFU Air Admittance Valve with White PVC Sch. 40 Adapter - Oatey 39260 Wall Box with Plastic Louvered Faceplate Air Admittance Valve, White - HeSun Washing Machine Outlet Box, 1/2 Inch Crimp Pex Inlet x 3/4 Inch MHT Outlet Connection, Pex Washer Laundry Box with Center Drain --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/12443771-oatey-sure-vent-1-1-2-in-2-in-160](https://www.desertcart.kg/products/12443771-oatey-sure-vent-1-1-2-in-2-in-160) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-13*
