Water is backing up into one of my kitchen sinks when draining the other side and when the washing machine or dishwasher are draining. It's a small amount, but enough to be disgusting and to leave residue in the sink. We live in the country and have a septic tank, which has shown no indication of being over full. We have tried pouring Liquid Plumber down the sink with no results. Can someone help me solve this problem?
