The picture attached is of the 2nd floor plumbing in a 3 floor building.
Today I was using the sink here on the 2nd floor and the upstairs apartment either flushed their toilet or also used some kitchen water. At the exact same time a load of water splurted out the washer drain pipe and then a load of sewage air.
This sounds like a venting problem, maybe it doesn't happen normally as the sink could unintentionally be used as a air vent in this pipe setup. But the water backing up is odd.
Any ideas what could cause that and how to fix?
