*by G***E on 9 December 2021*

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.
