Why Does My Toilet Gurgle After Flushing? Common Causes Explained

When using a toilet, some people may encounter a gurgling sound after flushing. This issue can be attributed to several reasons, which I will briefly explain below.

1、Toilet Clogging

The gurgling sound can occur if the toilet is blocked by foreign objects. For instance, if coins or other items accidentally fall into the toilet, it can lead to a blockage. Poor quality ceramic material can accumulate limescale, causing clogs as well. Additionally, regularly pouring food waste and contaminants into the toilet can also contribute to blockages. It's essential to promptly use a plunger or similar tools to clear the blockage, and if it cannot be resolved independently, consider calling a professional for assistance.

2、Drainage Pipe Blockage

If the drainage pipe connected to the toilet is blocked, it can also result in a gurgling noise when flushing. For example, during renovations, construction debris like cement, mortar, or bricks may inadvertently fall into the drainage pipe. If this occurs, you can open the inspection hatch to attempt to clear the blockage.

3、Vent Pipe Blockage

In a building, there are typically vent pipes and sewage pipes. If the vent pipe is blocked, air cannot escape from the drainage pipe, leading to a gurgling noise. If you suspect a blockage in the vent pipe, it’s advisable to contact the property management for help.

How to Deal with Toilet Clogs

If your toilet is clogged, you can use a plumbing drain cleaner to resolve the issue. When using a chemical drain cleaner, ensure to follow safety precautions and adhere to the instructions on the label to avoid excessive spillage that could irritate the skin. Alternatively, you can use a mixture of vinegar and baking soda for unclogging. A plumbing snake can also help in removing the blockage. If the clog is caused by a solid object, it may be best to seek professional assistance for clearing it.
