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. ## 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.sc/products/11548688-studor-20381-redi-vent-air-admittance-valve-with-recessed-box](https://www.desertcart.sc/products/11548688-studor-20381-redi-vent-air-admittance-valve-with-recessed-box) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-18*
