So the answer would no. You could flange it out if you had to make it work. **Q: what is the diameter of the bottom hole of the recessed box? 1.5” or 2” and is it threaded?** A: Both, 2&1.5”, 2” pipe slips over the connector and 1.5 slides inside of the connector of the box. No threads, it is for solvent connections. **Q: does this come WITH the air admittance valve as shown in the picture? is that for 1 1/2 drain vent, or 2"?** A: Mine came with everything shown; air admitance valve, mounting box, and the cover plate. Was a 2” kit as it was what I needed. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saves a lot of work by not needing to go thru the attic roof vent *by on Reviewed in the United States 6 April 2026* I had to move a bathtub drain and needed a way to vent it, I didn’t want to notch-cut thru 3 joints that would be located under the bathtub as it would weaken them, and an island-tub full of water with occupant is extremely heavy. This valve was my saving grace, It works perfectly and if your handy installation is relatively easy. It is well made and the wall box is just what I needed. Just make sure the vent is slightly above the bathtub overflow (or higher) so if the main drain gets completely blocked (rare occurrence) the water won’t be able to rise higher then the vent backup through the valve. The valve is designed to keep sewer gas out, it is not designed to stop water. ### ⭐⭐ Incompatible con tuberia de mexico *by on Reviewed in Mexico 10 April 2023* Cumple su funcionalidad, pero no es compatible con las tuberías PVC de méxico, tuve que buscar un adaptador y aun así quedó flojo y tuve que rellenar la junta con espuma ### ⭐⭐⭐⭐ Don't know yet *by on Reviewed in Canada 16 September 2018* I have not installed it yet but i do like the look and way it works will update the review when installation is completelater G ## Frequently Bought Together - Studor 20381 Redi-Vent Air Admittance Valve with Recessed Box and Grill, White - Studor 20380 Recessed Air Admittance Valve Box and Grill - Oatey Sure-Vent 1-1/2 in.–2 in. 160 Branch, 24 Stack DFU Air Admittance Valve with White PVC Sch. 40 Adapter --- ## 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.com.pa/products/304156867-studor-20381-low-profile-recess-box-with-grille-and-redi](https://www.desertcart.com.pa/products/304156867-studor-20381-low-profile-recess-box-with-grille-and-redi) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-09-11*
