One of the most common causes of a kitchen sink not draining is a clogged garbage disposal. Food particles, grease, and other debris can build up in the disposal, causing it to become clogged and preventing water from flowing through. To check if this is the issue, turn off the disposal and use a flashlight to look down the drain. If you see any food or debris, use tongs or pliers to remove it. You can also try running cold water and turning on the disposal to see if it helps clear the clog.1. Check the garbage disposal
If the garbage disposal doesn't seem to be the problem, try using a plunger to clear the clog. Fill the sink with enough water to cover the plunger and place it over the drain. Push down and pull up quickly to create suction and try to dislodge the clog. You may need to repeat this process a few times for it to be effective.2. Use a plunger
If the plunger doesn't work, a drain snake may be a more effective tool for removing the clog. Insert the snake into the drain and twist it as you push it through the pipes. This will help to break up and remove any clogs. You can also try using a wire hanger if you don't have a drain snake on hand.3. Try a drain snake
A natural and effective way to unclog a drain is by using a mixture of baking soda and vinegar. Pour a cup of baking soda down the drain, followed by a cup of vinegar. Let it sit for a few minutes before pouring hot water down the drain to flush out the clog. The chemical reaction between the baking soda and vinegar can help to break up and dissolve the clog.4.

The P-trap, or U-shaped pipe under the sink, can also become clogged with debris. Place a bucket under the P-trap to catch any water and then use pliers to loosen the nuts and remove the trap. Clean out any debris and then put the trap back in place. This should help to clear the clog and allow water to flow freely again.5. Check the P-trap
If you have a wet/dry vacuum, you can use it to help remove a clog from your kitchen sink. First, place a rag over the overflow opening and then create a seal around the vacuum hose and the drain. Turn on the vacuum and let it run for a few minutes to hopefully suck out the clog.6. Use a wet/dry vacuum
If your kitchen sink is connected to a dishwasher, a clog may be caused by a blockage in the dishwasher drain hose. Check to make sure the hose is not kinked or clogged. You can also try disconnecting the hose and running hot water through it to remove any debris.7. Check the dishwasher connection

They can be harmful to skin and eyes, so wear gloves and safety glasses. If the clog is still not cleared after using a drain cleaner, it may be time to call a professional plumber.8.
