Hey folks. I have a very foul odor coming from under the kitchen sink. I have traced it to the AAV. I tried replacing the AAV and still have the odor. I tried blocking off where the AAV screws in with duct tape and the oder went away. Any ideas what to look now? Does the AAV have an adjustment - couldn't find one. Finally, do I really need the AAV or can I just block it off? Thanks for the help!
