## Questions & Answers

**Q: What size is the inlet?**
A: The inlet fits a 2" studor.

**Q: can it be use in 2x3 stud wall**
A: It is 2 3/4" from the back of the enclosure to the back of the drywall flange. 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.
