Dishwasher not draining, kitchen sink and bathtub draining slowly?
Recently everything seems to be draining slowly. I snaked the bathtub and removed a chunk of hair but it's still draining slow. My dishwasher isn't draining properly and the sinks partially fill up when dishwasher is running. Also the kitchen sink drains slowly. Could this be an air vent block? Last winter we had a similar issue with our kitchen sink, after snaking, baking soda and vinegar etc it still would not drain well. We thought it might be ice buildup in the pipes? If it is an air vent block how would one go about unclogging? Also is there any chance the air vent would come out of the side of the house and not the top?
