Today my wife was in the kitchen and black water came up through the

first-floor kitchen drain back up when no water was running anywhere
in the house? I could understand it if a basement drain had also
backed up.


was it extremely windy?

It was not windy; I thought of that. Nor was the dishwasher running. Today the drain is pretty well clogged. Drano didn't help. Tomorrow I remove the traps on the sink and disposer and clean it all out.
