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!
It looks as if your sinks are connected to they drain into one pipe. One fix is to get 2 one way valves so when you drain the sink, it goes out the valve and if you have the one on the other side, it cant go back into it.
