How to Fix a Gurgling Toilet

Gurgling ToiletOther than when flushing and refilling the tank, toilets are supposed to be quiet. However, some homeowners have reported bubbling in the water and the strange strangling sounds. This is not normal. We’ll explain what causes a gurgling toilet, why it’s bad, and how to fix it.

Why Does a Toilet Gurgle?

Faulty Tank Equipment

The tank interior contains a flapper and a float and fill system. If any of these components are faulty or loose, the toilet may make a gurgling noise or sound.. All of the parts inside the tank are available at your local hardware store. A residential plumber can replace all worn parts.


A clogged toilet will gurgle and produce bubbles when it flushes. This is where a trusty plunger comes in handy. The suction should loosen the blockage. If that doesn’t work, then contact a professional. A plumber may have to use an auger and access the pipes through the toilet vent located on the roof.

Clogging may also occur in the tank’s water line due to buildup of calcium and magnesium from hard water scale.

Air in the Pipes

Gurgling may also be the result of air in the water fill line. This causes the fill line to spit and spur, which leads to the gurgling. To remove the air, give this a try: turn on all the faucets in the home and let them run until the water is flowing smoothly. If this doesn’t fix the problem, then the air may be entering from a hole in the pipe.
