If your kitchen sink won't drain after plunging, the first thing you should check is your garbage disposal. Sometimes, food particles or other debris can get trapped in the disposal and cause a blockage. To check this, turn off the power to your disposal and use a flashlight to look inside. If you see any obstructions, use tongs or pliers to remove them. Once you have cleared the disposal, turn the power back on and try running the water to see if the blockage is gone.Check the garbage disposal
If the garbage disposal doesn't seem to be the issue, the next step is to try using a drain snake. This tool is designed to break up and remove clogs in your pipes. To use a drain snake, insert the end with the auger into the drain and twist it as you push it down. This will break up any blockages and allow water to flow freely again. If you don't have a drain snake, you can also try using a wire hanger or a plunger with a snake attachment.Use a drain snake
The P-trap is the curved pipe under your sink that is designed to catch debris and prevent it from entering your pipes. However, this trap can also become clogged over time. To check the P-trap, place a bucket or bowl under the pipe and use a wrench to unscrew the nuts at each end. Once the trap is removed, clean it out and then reattach it. This should help to clear any blockages and allow your sink to drain properly.Check the P-trap
If the above methods don't seem to be working, you can try using a chemical drain cleaner. These products work by breaking down any organic materials in your pipes that may be causing a blockage. However, be cautious when using these cleaners as they can be harmful to your pipes and the environment. Make sure to follow the instructions carefully and use protective gear when handling these chemicals.Try a chemical drain cleaner
If you have tried all of the above methods and your kitchen sink still won't drain, the issue may be a clog further down in your pipes. You can try using a plumbing snake or auger to reach the clog and clear it out. If you are not comfortable doing this yourself, it's best to call a professional plumber to handle the job.Check for clogs in the pipes
If you are using a plunger to try and clear a blockage in your kitchen sink, it's important to use one with a flat bottom. This will create a better seal around the drain and allow for more effective plunging. You can also try using a plunger with a snake attachment for extra power.Use a plunger with a flat bottom
Another possible cause of a kitchen sink not draining after plunging is a blocked air vent. This vent is designed to allow air to flow through your pipes and prevent suction from forming, which can lead to clogs. You can check the vent on your roof or under your sink to make sure it is not blocked by debris. If it is, use a wire brush or a plumbing snake to clear it out.Check the air vent
If you prefer to use natural methods, you can try making your own drain cleaner using ingredients you may already have at home. One popular recipe is a mixture of baking soda and vinegar. Simply pour half a cup of baking soda down the drain, followed by half a cup of vinegar. Let it sit for a few minutes, then pour hot water down the drain. The chemical reaction between the baking soda and vinegar can help break up any clogs and clear your pipes.Try a homemade drain cleaner
