Studor 20349 Redi-Vent Air Admittance Valve with ABS Adapter, 1-1/2- or 2-Inch Connection

Cumplió con las expectativas para lo cual la compré satisfecho al 100

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.

I had a stinky bathroom for a very long time. Thought the vent was plugged or pipes backed up. Nope. My really old air admittance valve had finally fallen apart. This is a different style and did the trick right away. And me- a single grandma was able to replace it so easily.

Easy to install.

Replacing these did help with tank odor inside the camper but did not eliminate it completely. I still recommend replacing them.
