Answer: 
From the manufacturer's literature:
Sure-Vent® AAV are intended for installation in the
confines of a structure, cannot be exposed to outside
elements and are intended for use between -40° F and
150° F. AAVs must be accessible for inspection and
service.

Maybe. Be aware it is designed to handle up to 10 PSI of pressure. Figure almost half a pound per foot of elevation. So if the basement in under a single level home it should be fine, but in a two story it might fail to hold the pressure.

To fix it, simply poor a pint to a quart of water down the floor drain every 3 months or so. Read Less

Answer: 
I would only use on a sink. If your going to use it for the toilet and sink I would go with the next size up, it would fit on a 3" and 4" with the adapter.

Answer: 
The building must have at least one vent that vents through the roof. The AAV can be used where you do not wish to penetrate the roof.

Sure-Vent 1-1/2 in. x 2 in. PVC Air Admittance Valve is rated 4.8 out of 5 by 7.
Rated 5 out of 5 by from Works Great so Far My sink would gargle when trying to drain large volumes of water. Based on how the plumbing was originally installed, the air vent is too far away from the trap, creating the vacuum. This solved the problem and has been working great so far. Although the actual price to manufacture this product is far lower than the sale price, I still gave it an excellent value because I compared the price of this to the price of breaking into my walls to fix the air vent problem. Great product and easy to install!

Rated 5 out of 5 by from Great for gurgle and drainage issues This is a great product for resolving suction issue that can end up letting sewer gas back into house. Used this in my kitchen where the old cast iron vent rusted in wall. This was a quick resolution for fixing a gurgling sound and slow drainage in kitchen sink. I would recommend to anyone who doesn't want to tear into existing walls to repair or install a vent stack.

Rated 5 out of 5 by from Big help for installing utility sink in basement The air admittance valve makes it relatively easy to install a new sink in an existing structure by making it unnecessary to find or add a vent line. This unit is well made, and the instructions are clear and concise. It fits either a 1-1/2 inch or 2 inch drain pipe, which will cover most installations.

Rated 5 out of 5 by from Performed as advertised!! The vent was very easy to install even under the sink where it was needed. I was skeptical at first if the vent would fix the drain problem I was having, but after the installation the problem was gone.

Rated 5 out of 5 by from Sure-Vent I gave the rating on value average because it was a small plastic piece that was overpriced for the amount of materials it contained and that it was made in China for peanuts. I don’t know the quality since it was just purchased and I don’t know how long it will last. It was very easy to install especially since it was only the top piece that needed to be replaced. The old piece was simply unscrewed and the new replacement piece screwed back on.

Rated 3 out of 5 by from Sure Vent The vent still seems to allow sewer smell back into the under-sink space.

Rated 5 out of 5 by from Works as intended Served its intended purpose. However, screwing valve onto adapter can only be done by hand as there are no flat faces for a wrench.
