I have a 3 year old house in the suburbs with city sewer. My Washer is above my basement. The drain hose goes into the sink next to it. When the washer discharges, it create a flood in the utility room below from the drain. When I fill the sink with regular faucet water and drain it it does not backup. It only backs up from the soap water. I had a plumber snake out 80 feet and it did not work. Does the bubbles from the rinse water cause problems? Should I switch detergent? Thanks

As a rule when this happens it indicates a blockage downstream from the floor drain where it backed up. However since you had a plumber snake the line out and you can let a sink full of water go without backing up about the only thing left is the type of detergent that you're using. Change your detergent and let me know. Good luck, Tom
