When I fill one side and release water the other side will back up
When I fill one side of double sink in kitchen and pull the plug out the water in opposite sink will have water back up into it. Have used draino but it still happens. So if I wash any dishes in sink I have learned not to release till I have dried dishes that I put in empty side.
How can I stop this?
Thanks for any replies!
