If your double kitchen sink is not clogged but won't drain, the first thing you should check is the garbage disposal. This is often the culprit when it comes to slow or clogged drains. Garbage disposal units can become clogged or jammed with food particles, which can prevent water from draining properly. To check if this is the issue, turn off the power to the disposal and use tongs or pliers to remove any visible debris from the unit. Then, run water through the disposal to see if the problem is resolved.1. Check the garbage disposal
If the garbage disposal is not the issue, the next step is to try using a plunger. This common household tool can be effective in clearing out any clogs in the drain. Plungers work by creating suction and pressure to dislodge and push any clogs through the pipes. To use, place the plunger over the drain and vigorously pump up and down. If the water starts to drain, continue plunging until the sink is completely clear.2. Use a plunger
If a plunger doesn't do the trick, a drain snake may be the solution. This tool is designed to reach deep into the pipes and grab onto any clogs, allowing you to pull them out. To use, insert the drain snake into the drain and turn the handle to push it further into the pipes. Once you feel resistance, twist and pull the snake back out, hopefully bringing the clog with it.3. Try a drain snake
The P-trap is a curved section of pipe located under the sink that is designed to trap debris and prevent it from clogging the pipes. However, this also means that the P-trap can become clogged itself. To clean it out, place a bucket under the trap and use pliers to loosen the slip nuts on either end. Remove the trap and clean out any debris, then reattach it and run water to see if the drain is clear.4. Clean the P-trap
Air vents are essential for proper drainage in your kitchen sink. These pipes allow air to enter the plumbing system, preventing a vacuum from forming and blocking the flow of water. If the air vent is blocked, it can cause slow or clogged drains. Check the air vent on your roof or exterior wall to make sure it is clear of debris or obstructions.5. Check the air vent
If none of the above methods work, you may need to turn to a chemical drain cleaner. These products are designed to dissolve any organic material clogging the pipes. However, they can also be harsh and damaging to your plumbing, so use them sparingly and follow the instructions carefully. Also, be sure to wear gloves and eye protection when handling these chemicals.6. Use a chemical drain cleaner
If your double kitchen sink is still not draining properly, the issue may be in the main drain line. This is the large pipe that connects all of the drains in your house to the sewer line. If there is a clog in the main drain line, it can affect all of your sinks and drains. Check for a clog by running water in other sinks and tubs to see if they are also draining slowly. If this is the case, you may need to call a professional plumber to clear the blockage.7. Check for a clog in the main drain line

If your double kitchen sink is old or has a damaged drain assembly, it may be time to replace it. The drain assembly is the part of the sink that connects to the pipes and controls the flow of water. Over time, these parts can wear out or become damaged, leading to drainage issues. You can purchase a replacement assembly at a hardware store and follow the instructions to install it yourself, or hire a professional if you are not comfortable with DIY plumbing projects.9.

If you don't already have a garbage disposal, consider installing one to prevent future clogs and drainage issues. Garbage disposals can grind up and dispose of food scraps, making it less likely for food particles to clog your drains. They are also relatively easy to install and can be a worthwhile investment in the long run. In conclusion, if your double kitchen sink is not clogged but won't drain, there are several steps you can take to try and resolve the issue. From checking the garbage disposal to installing a new drain assembly, these methods can help get your sink back to functioning properly. If the problem persists, don't hesitate to call a plumber for professional assistance.
