Studor 20349 Redi-Vent Air Admittance Valve with ABS Adapter

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.

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

I believe its doing a good job! The one i removed was absolutely nasty.

Had to replace same model that failed during sink clog episode after it started allowing water out, which it is designed not to do. I confirmed the failed device had to be replaced by tyring to float it in a cup of water and within 20 seconds it submerged below the level of the side vents. A working device would have kept afloat above those vents. This new one has a 2 in 1 sized adapter which I don't care for because it is larger. I preferred to keep the old adapter in place since it takes up less space. Note that product came without instructions, just a QR code. You also need to buy teflon thread seal tape to install it, not included. I like that it has warranty but only for the original purchaser, which is why I could not cash in on the failed unit. It is not transferable.

Perfect size I was looking for. Fit my project easily.

The Redi- Vent makes it doable to vent a sink with out the need to cut thru the roof to extend the vent pipe

Works perfectly

Arrived and works as advertised.

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.

Easy to install.

Ok

I’ve had it couple weeks and works quite well hopefully it will last long time
