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.

water backs up from the drain in my dishwasher and smells. what is the problem?


Two things can cause this problem:
1. The check valve in your dishwasher may be defective, allowing water and food debris to seep (or run) back into your dishwasher.
2. Your drain hose may not be "mounted up" the way it should be. Look under your sink. Look at how your drain hose is connected to your garbage disposal. If the hose runs down to the floor of your cabinet and into your dishwasher, that is wrong. Instead, it should be mounted up so that water from the sink and garbage disposal would have to flow up first to get into the dishwasher. If you do this, then even if you have a bad check-valve in the dishwasher, it will prevent the problem (or greatly reduce the problem) of dirty water flowing back into your dishwasher.

why does kitchen sink drain water from drain side to garbage disposal side


The two drains are connected, but below the disposal. Likely if it's not draining down, you still have a clog, and the person the "cleared" the drain didn't.

How do I drain my dishwasher?


As far as draining the backed up water you may have to run a short cycle wash to help it. In California homes we have a by-pass vent which runs from the dishwasher drain hose up to a port in the kitchen sink. From there it is attached to the side port of a garbage disposer. In the event of a backwash the by-pass vent is high enough that it can't reach a level that wiould flow back into the dishwasher.

Our sink and garbage disposal was clogged up. We got the sink unclogged, but the dishwasher had dirty water in the bottom and won't drain.


Your dishwasher drains into the garbage disposal. It you tried to use a plunger to clear your clogged sink or run the disposal with to much junk in it you may have force debris into the dishwasher drain hose. With both the dishwasher and garbage disposal disconnect from power disconnect the dishwasher drain hose from the garbage disposal. This is usually about a one inch black hose. Clear out any debris in the hose and inlet nipple on the garbage disposal. If debris is compacted far down the hose it will need to be disconnected from the dishwasher end and remove to clear the blockage.

Good luck!

I have a Badger 5xp & a double sink. When I turn the disposal on I get a small eruption of water, air and disposed of debris from the other drain.


Take apart the tubular drain pipes beneath sink and clean out everything.
Take photos before removing pipes so parts go back together easily.
Loosen 2 nuts on trap, and trap falls loose.
Remove 2 bolts/screws and remove tailpiece from side of disposal.
Then run snake down drain line leading away from sink to make sure blockage is removed.

I wrote ez disposal steps that give tips on reconnecting tubular drain pipes:
