I seem to have a failed AAV. At first, my drain line was blocked with crud. I cleaned all the crud and snaked into the wall. All is clear. However, while that fixed one issue, I still was unable to drain. I was flabbergasted and I finally buttoned up the pipe and removed the AAV and voila, the water drained. I was able to run the water and no more did the water back up. But once I put the AAV back, bam, no more drainage...or extremely slow drainage. The AAV, when removed seemed to still have a flapper working as I could feel it when I tipped it or shook it.
So, here is the AAV....I have no experience, thus here to ask those who do and/or are pro's...is there a specific replacement AAV I must adhere too or can I use any AAV that I can screw into the 1-1/2", 2" as stamped on my existing AAV?
I would prefer to get/replace with same exact, but unsure if thats attainable or maybe I dont since the damn thing is only 14 years old!
Here is my current
