What Causes a Gurgling Toilet?

While your toilet “gurgling” when you flush the toilet may not seem like a serious problem, it may be a sign that the plumbing in your bathroom is not functioning properly.

Clogs
The weird sound may be the result of air escaping a blocked pipe. Sediment, minerals, debris and non-flushable items are common culprits of clogged pipes. While a plunger will clear minimal blockage near your toilet bowl, the clog may be occurring in any part of your sewer line (including the septic system).

Defective tank equipment

The components of your toilet (the float, fill system and flapper) allow it to flush properly and refill with clean water. However, these components can become corroded over time. Faulty toilet hardware can cause disruptive noises and even reduce the efficiency of your home’s utilities. Because identifying and fixing issues with tank equipment can be difficult, it’s best to seek professional plumbing services in St. Charles, IL, for the job.

Reverse suction

When the water in your toilet’s built-in P-trap (the device that prevents odorous gas in drains and sewers from rising) is pulled out of the bowl and back into your plumbing system, reverse suction occurs. This is usually due to a lack of proper venting. Other appliances such as washing machines can create backflow that will pull air from your toilet, also resulting in a gurgle.
