If your kitchen sink won't drain, the first thing you should check for is a clogged drain. This is a common issue that can be caused by a variety of things, such as food scraps, grease, and other debris getting stuck in the pipes. The water in your sink may drain slowly or not at all if there is a clog. To fix this issue, you can try using a plunger or a drain snake to remove the blockage.1. Clogged Drain
In some cases, the clog in your kitchen sink may be caused by blocked pipes. This can happen if something gets lodged in the pipes, such as a large piece of food or a foreign object.

Another common issue with kitchen sinks is a slow draining sink. This can be caused by a clog, as mentioned above, but it can also be due to a buildup of soap scum or mineral deposits in the pipes.

A plunger is a common tool used to unclog drains and can be effective for smaller blockages in your kitchen sink.

You may need to repeat this process a few times to completely clear the drain.5. Plunger
A drain snake, also known as a plumber's snake, is a long, flexible tool used to remove clogs from drains. To use a drain snake, insert it into the drain and slowly push it through the pipes. When you encounter the clog, twist and turn the snake to break it up and remove it. Drain snakes can be purchased at most hardware stores and can be a useful tool for stubborn clogs.6. Drain Snake
