What Causes a Sink to Gurgle When You Flush a Toilet?

The most common cause of a gurgling sink is a clogged drain. When you flush the toilet, the water from the toilet bowl flows down the drain and pushes the clog further down the drainpipe. This can cause the air in the drainpipe to become trapped, which can create a gurgling sound.

Other possible causes of a gurgling sink include:

• A loose or damaged drain pipe.

How Can I Fix a Gurgling Sink?

If your sink is gurgling because of a clogged drain, you can try to clear the clog yourself using a plunger or a drain snake.

To use a plunger, first fill the sink with enough water to cover the bottom of the plunger. Then, place the plunger over the drain and push and pull the plunger up and down vigorously. The suction created by the plunger should help to loosen the clog and push it down the drain.

If you do not have a plunger, you can try using a drain snake. A drain snake is a long, flexible wire that is inserted into the drain to loosen and remove the clog.

To use a drain snake, first insert the snake into the drain until you feel resistance. Then, slowly turn the snake clockwise while pulling it out of the drain. The snake should help to loosen the clog and pull it out of the drain.

If you are unable to clear the clog yourself, you will need to call a plumber to fix the problem.
