## Questions & Answers

**Q: So can this vent inside a basement with no odor? We bought a house that has zero roof vents. Can this be used in place of those?**
A: Don't think I 'd iinstall it in the basement.  It needs to be above the fixture(s)  that it vents.  I've used smaller AAVs for indivuaul fixtures and placed them under the cabinet/sink or in the wall.  The larger AAVs are desgined to handle several fixtures and replace the need for a large vent that penetrates the roof.  These I've placed in the attack (below the roof but inside the building) and have not had any problems.

**Q: How long does one of these last until it needs to be replaced? Is there a way to tell if it has failed besides escaped sewer gas smell?**
A: Package shows limited lifetime warranty. I assume when you smell sewer gasses, it has failed, but I really don't expect it to fail. All I know, is that it works and so far, I'm very pleased with the performance.

**Q: Does it come with a push-fit connector donut (wide o-ring) for connecting to inside of 4" pipe? Shown on spec sheet, but not for item.**
A: No… just the item. Fits inside 4” sch 40 PVC coupling or 4” Fernco rubber coupling

**Q: Is it acceptable to use a rubber boot?**
A: This goes INSIDE the attic. No boot needed.
