If your kitchen sink won't drain, the first thing to check is your garbage disposal. This is a common culprit for clogged drains, especially if you frequently put food scraps down the drain. Turn off the disposal and check for any large or hard objects that may be blocking the blades. You can use tongs or pliers to safely remove any debris. Once cleared, try running hot water to see if the sink drains properly.Check the garbage disposal
Another potential cause for a clogged kitchen sink is the drain stopper. This is the small device that sits in the sink basin and can be lifted or pushed down to allow water to drain. If the stopper is stuck in the closed position, water will not be able to flow through the drain. To check this, simply lift the stopper and see if the sink begins to drain. If it does, you may need to clean or adjust the stopper to prevent future clogs.Check the drain stopper
If the garbage disposal and drain stopper are not the issue, you can try using a plunger to clear the clog. Fill the sink with a few inches of water and place the plunger over the drain. Push down and pull up several times to create suction and hopefully dislodge the clog. This method works best for small to medium sized clogs and may require a few attempts to fully clear the drain.Use a plunger
If the plunger doesn't do the trick, you can try using a drain snake to remove the clog. This tool is a long, flexible wire with a small auger on the end. Insert the snake into the drain and twist it as you push it further down. This will help break up and remove any blockages in the pipe. Once finished, run hot water to flush out any remaining debris.Try a drain snake
The P-trap, also known as the U-bend, is a curved pipe located under your sink. This pipe is designed to trap debris and prevent it from entering the main drain. However, these traps can also become clogged with buildup or debris. Place a bucket under the trap and use pliers to loosen the connections. Once removed, clean out any debris and reattach the trap. This should allow water to flow freely through the drain once again.Check the P-trap
A natural and effective way to unclog a kitchen sink is by using a mixture of baking soda and vinegar. This combination creates a chemical reaction that can help break up and remove clogs. Pour ½ cup of baking soda down the drain, followed by ½ cup of vinegar. Let the mixture sit for about 15 minutes before flushing with hot water. Repeat if necessary.Use a mixture of baking soda and vinegar
If you have a dishwasher connected to your kitchen sink, it's important to check this appliance as well if your sink won't drain. Some dishwashers share the same drain as the sink, so a clog in the dishwasher may be causing the issue. Run the dishwasher and see if the water drains properly. If not, you may need to clean or unclog the dishwasher drain hose.Check the dishwasher
