I have a gurgling sink after a remodel project.
The old setup was a large cement sink in the basement where the washing machine emptied into. This sink had no vent pipe or visable trap, but it worked fine. The drain pipe went right into the cement slab. I assume after this point the drain pipe connects to the main waste pipe which connects to the city sewer.
We replaced this sink and I added a trap and an AAV. We also remodeled the kitchen directly above it and moved the kitchen sink which now drains into the same drain pipe. I added an AAV to this sink as well.
Now, when the washing machine empties into the basement sink, the kitchen sink gurgles a bit.
