The wash sink in my bathroom has a very slow drain. I have used commercial drain cleaners many times but now even they will not work. The back up is not in the gooseneck but after it enters the wall. This is an older house with iron drain pipes. When I plunge it I get some nasty looking brown gunk coming into the sink. Does anyone have any suggestions other than "call a plumber". Thanks.
