Our home is in a rural area and we have a septic system. In the lower level of our home, we have a septic pit that handles the gray and septic waste from a 3 piece bathroom. The septic pit is directly vented to the main vent of the building that leads to the roof. When the septic pit is full, a pump comes on and pumps the effluent to the main septic line for the septic system. But the pump is so powerful that every time it worked, it also emptied every P trap and toilet in the house. This is not only annoying but also a very dangerous situation that then allows septic gases to enter the home. I purchased this Air Admittance Valve and attached it above the 2" vent pipe coming directly out of the septic pit. It works perfectly, drawing only the air from the immediate area and not from the entire venting system. No more worries about septic gases. However, the 2" ABS adapter that comes with the product is only designed to take the Air Admittance Valve that screws in at one end, and a 2" ABS pipe that you seal to the other. This was fine for me, but if you were intending to attach it to a 1 1/2" ABS pipe, you would also need an additional adapter to do so.

We had stinky grey tanks on our brand new Grand Design 397THS. After googling and watching some videos, this product was recommended as the first course of action. I was skeptical for sure - our rig is brand new and I was doubtful this little part would save us from the killer stench that seemed to be emanating out of the kitchen sink. It is literally replaced in under 30 seconds - unscrew the old part, screw in this part. I installed it over the weekend and 3 days later I still have been living in nasal bliss! I will update in another week or so just to confirm we have been saved :) UPDATE Grey tank smell GONE! Using this for a number of weeks now and the smell has not returned, so success :)
