## Questions & Answers

**Q: can it be mounted outside upside down?**
A: I believe this would allow water to sit inside it and affect it's capability to work properly. Also, if you live in a cold climate then it could freeze.

**Q: Is this an actual air admittance valve, or simply a charcoal filter?**
A: It's both a vent and a filter. I use it to keep rain and snow out of the venting system. The air comes out the bottom of the cap. Works fine for me.

**Q: Does this include the filter cartridge? Thanks**
A: Yes - it includes the filter.

**Q: Is it a 2’’ Studor vent?**
A: No, 4"
