What Can Cause a Toilet to Gurgle?

Why Is My Toilet Making a Gurgling Sound?

Typically, when you flush your commode, you’ll hear water leave the bowl and re-enter — but there’s always a chance you might hear a strange gurgling sound when you least expect it. Although it may seem as if you can use your toilet plunger to help save the day, the root of the problem may lie deeper and require a professional’s assistance. Here’s what you need to know.

Possible Reasons Why a Toilet Starts to Gurgle

Lack of Proper Venting

One reason why your toilet may be making that gurgling noise is due to a lack of proper venting. In this case, a reverse suction occurs in the P-trap when the water is pulled out of the bowl. And without the appropriate ventilation, various appliances in your humble abode (i.e., your dishwasher) can pull air, causing your “throne” to create that dreaded gurgling sound.

A Clog in Your Sewer Line

Unlike a traditional clog in your toilet that can be solved with a plunger, there may be a deeper obstruction within your sewer line. When this is the case, air escapes from the blocked pipe, causing the gurgling sound. Some of the items that could be causing the blockage include:

  • Minerals

  • Sediment

  • “Flushable” wipes

  • Tree roots

To help get to the bottom of this problem, you’ll need to rely on the help of a professional plumber. Using a toilet auger, our team of experts can navigate the pipe and snake out the clog that may create the gurgling sound.
