Question– “I have two connected kitchen sinks. I tried a small snake, unclogging liquid and soda and vinegar, and hot water and it still won’t unclog the kitchen sink. What should I do?” 

Answer– In our opinion, you need a longer snake. The snake needs to be long enough to go from the kitchen sink to the main line drain that it ties into to be able to clear the clog.  If you don’t have a longer snake it maybe cheaper to call your local plumbing company to do this for you since long drain snakes are expensive to buy.
