Kitchen sink won't drain, seems like there is an obstruction. Liquid drain cleaners have not worked.
This issue is with the left side of a double kitchen sink, which will not drain at all. The right side drains fine. We do not have a garbage disposal or dishwasher. Liquid drain cleaners have not worked. My husband used a snake in the sink, it only went in about an inch and it felt like it was hitting something very hard like metal all th way around. What could be the problem?
