English Translation
Bubbling or gurgling sounds from the toilet are usually a warning sign of trapped air somewhere inside the piping system. This issue must never be ignored, as it may indicate a clogged sewer pipe or a problem with the ventilation system.
Quick Answers
- A blocked vent pipe causes trapped air pressure.

Real-Life Scenario
A homeowner reported that toilet bubbling only happened when the washing machine drained. The actual cause was a partially blocked main sewer line, which created negative pressure inside the pipes.
