Our basement shower hasn't been draining properly for months. During the course of a 5-10 minute shower water will back up to above ankle height. Drain cleaner had no effect. I just pulled a wad of hair out of the drain and tried snaking it. Now dirty grey water is backing up out of the drain, especially when I run the sink next to the shower. Any idea what's wrong with the drain?
I got the snake in no more than three feet. I cranked it until it developed what appears to be a permanent kink.
All other sinks and showers appear to be draining correctly.
