I own one condo unit on the fifth floor of a seven floor building. In the kitchen there is a dishwasher sink and garbage disposal. The drain is very slow and backs up into the dishwasher. Took off garbage disposal and ran a 25 foot snake through as well as using liquid plumber and everything appears to be clean. If I fill the sink with water it bubbles as it drains and goes slow but if I turn on the disposal it drains normally. With my limited knowledge this leads me to believe that there is a vent issue. I don't have access to the vents as they are in the common part of the building.
My question: Can I simply add an AAV or a studor vent right at the fixture, underneath the sink, to help compensate for a potentially blocked vent pipe? If so is there a specific one to use?
