Why would using our kitchen sink or dishwasher cause this odor in upstairs bathroom?
In the kitchen, there is a double sink, with a dishwasher connected to a garbage disposal, on the drain to the right, and an AAV on the drain to the left.
No odor on the level with the kitchen when using sink or dishwasher.
There’s water in the traps of bathroom fixtures upstairs (no siphoning). The AAVs in the kitchen and bathroom have been replaced. There’s no clogged drains in kitchen or bathroom. I’ve used Bio-cleaner, a powder bacteria drain cleaner, on all drains to no avail.
