My bathroom sink backs up to my kitchen sink both seem to back up when I do dishes toilet and shower have no problems I have had soneone come in and snake out drain and flows fine for a while than when I do dishes it backs up into bathroom sink and takes forever to drain what is the problem

More details please,
Howe old ism your home?
Do you have a dishwasher? Disposal? Are your kitchen and bathroom back to back?
When you have it snaked out do they snake from a roof vent or from under the kitchen sink?
Back to you, Tom

Your drain pipes look a bit like branches on a tree all leading to a trunk. Your clog is in one branch but before the trunk. Whoever did the roding for you either pushed the clog downstream or just didn'treach it. How long ago did he do the rodding and how much did you pay?
