Hello all.
I am finishing up a bathroom in our basement and we were "lucky" to have a rough in already in place. According to blueprints it was 3 pipes. 1 for shower with built in trap, 1 toilet, and 1 sink.
We did not add a shower so that one is capped and unused. We added a toilet and a sink. On the sink line we included an AAV based on local inspectors suggestion as a need. We have one other tub sink in the basement that was original that had an AAV on it.
So we installed the toilet and sink and the sink works good. But the toilet will not flush well. It goes down but very very slowly.
To test I did a few things.
1. removed the AAV on the sink next to toilet.
RESULT: The toilet flushes well, but I hear ALOT of bubbles and air movement in the opening where the AAV would be.
2. put the AAV back on.
RESULT: the first flush or two will work, but I get air and water movement in the SINK next to the toilet. From that point on, the flushing is back to minimal slow drain only.
I believe I have a positive pressure problem? Everything I was told was a wet vent like I installed would work. But it is obviously not.
Any ideas what I can try next? There are no other known issues with plumbing in the house. Here are pictures of the rough in before work, and the AAV installation. Last is a video of what it sounds like when the AAV is removed and the toilet is flushed.
Thanks for any tips. (I have called a plumber for arrival next week, but I am trying to see if I can get to the root myself before then)
