Hey there folks. First time to the forum. I had a remodel done where I added a tub to my bathroom system. The toilet and tub are wet vented to the basin, which has the dry vent. The issue I have is that when the toilet is flushed (only certain times), the tub has a gurgling noise. I think the wet vent setup is syphoning from the tub's P-trap. Running water remedies the noise... I don't let it get too bad (meaning there has been no odors).
To permanently remedy this and to avid the occasional running of water in the tub, can I increase airflow or prevent the negative air pressure somehow by adding an AAV to the basin after its p-trap? I know the right way is to vent the tub, but everything is in cement (tiles are in place) and I'm out of money.
See images below to hopefully better explain my dilema.
