i am in a condo association for a triple decker. we have many over flows. I think that it is related to a washer in basement that is not vented combined with extremely high usage of the washer. sometimes 25 cu ft /hr for 12 hours straight. its location is very close to where the kitchen stack sewage line merges with the bathroom stack sewage line. my friend says that while the washer is not professionally vented, the drain pipe is loosely connected and therefore air is getting in. i think that he is wrong, and there is a reason why code requires proper venting for washing machines.
