What do you do now? Fortunately for you, this frequent problem can be easily solved, and you can incorporate multiple methods to ensure that it will not get stuck again.

Why does the kitchen sink drain flange become stuck?

How to Replace a Sink Strainer?

If the problem persists even after unclogging the sink, then you may need to replace the sink strainer. This may seem like a daunting task, but it is a lot easier than you think assuming that you have the right tools for the job.

Step 1: Remove the Current Sink Strainer

To remove the existing sink strainer, unscrew it from the sink using a screwdriver or wrench. If the strainer is difficult to remove, you may need to use some pliers.

Step 2: Clean out debris

Once the strainer is removed, clean out any debris that may be stuck in the drain. This can be done with a plunger or a snake.
