Backed Up Kitchen Double Sink Fix with Garbage Disposal- Quick and Simple Fix
Here's how to fix a backed-up double sink (running water down one side/sink causing dirty water to well up out of the drain on the other side, with slow or no emptying). Note that this quick-and-easy tip only works if you have a functioning garbage disposal.
What you will need: a stopper, and possibly a clean toilet plunger (the cup-shaped kind that stands on its own, not the kind that is bulb-shaped)
Stopper up the side in which the water is rising up out of the drain. Make sure you hold down the stopper as well; if you don't, the stopper will shoot up on a geyser of dirty water when you perform the next step. Once you have the stopper in place and are holding it down, run water on the other side/sink and turn on the garbage disposal. Once you have done that for a reasonable amount of time, shut off the garbage disposal and water, and unstopper* the other side. Run water on both sides to make sure everything is draining properly. Doing this should save you the hassle of taking the pipes apart or plunging one side repeatedly to clear the clog.
*Note: If the stopper is stuck, place the plunger so it completely covers the opening the stopper is stuck in and give it two good plunges. The plunger should create a vacuum that will suck out the stopper, and is more effective than you trying to pry or pull on it. Do this ONLY after you have shut off the garbage disposal and water.
What is happening is that there is a clog in your pipes. When water goes down one side, it hits the clog somewhere in the pipes, has nowhere to go, and gets pushed back up the pipe leading to the other side of the double sink. By stopping up the side without the garbage disposal, you are creating a barrier preventing the water from coming back up. At the same time, the garbage disposal running on the other side is forcing the water down. Since the water now cannot escape up the stoppered side, it has nowhere to go but down, forcing the clog out with it.
