If your kitchen sink has started making gurgling sounds, the most common culprit is a clogged drain. Over time, food particles, grease, and other debris can build up in your drain and cause blockages. This can disrupt the flow of water and create air pockets, resulting in gurgling sounds. To resolve this issue, you can try using a plunger or a drain snake to clear out the blockage. If that doesn't work, it may be time to call a professional plumber to thoroughly clean your drain.1.

Another possible reason for gurgling sounds in your kitchen sink could be air in the pipes. This can happen when there is a leak or crack in your pipes, allowing air to enter the system. As water flows through the pipes, it can cause the air to bubble and create gurgling noises. If you suspect this is the issue, you should have your pipes inspected by a plumber and repaired if necessary.2. Air in the Pipes
The plumbing vent is a crucial component of your kitchen sink's drainage system. It allows air to escape as water flows through the pipes, preventing air pockets from forming and creating gurgling sounds. However, if the vent becomes blocked by debris or animals, it can disrupt the airflow and cause gurgling noises. In this case, you may need to have your vent cleaned or repaired by a professional.3.

You can try cleaning the drain trap yourself, but if the issue persists, it's best to have a plumber take a look.4. Faulty Drain Trap
