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?

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?

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.

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?

This goes INSIDE the attic. No boot needed.
