When it drains, it pressurizes the box. The studor only lets the air in and not out. So this is where I need help. What can be done to have this work right? I can't leave the vent open cause it will stink and also allow the gases to come out. I need help. Thanks in advance.

Your plumber needs to come back and correct his mistake. The pit vent MUST be a separate and vent air out as well as in. A Studore Vent will only allow air to vent in. The solution is to remove the AAV and extend the vent line to the outside, (do not tie back to the house vent system). The cost of this should be on the plumber who didn't complete the job. Good luck, Tom

Had the plumber come back and fix it up. In one area, he actually used a half in pipe and tied it in with the sewar vent. The bar sink he tied into the sewar line itself. Everything seems to be OK now, but is tying into the sear line OK? It seems to work OK now but want to make sure it was OK to do
