Why Does The Toilet Water In Australia Flow Backwards?
What To Know
- The direction of toilet water flow is primarily determined by the design of the toilet bowl, the shape of the drain, and the initial force of the flush.
- The Coriolis effect has a negligible influence on the direction of the flush, and the primary factors that determine the water’s flow are the toilet bowl design, drain shape, and initial flush force.

The age-old question of “does the toilet water in Australia flow backwards” has puzzled many travelers and sparked countless debates. This blog post aims to delve into the fascinating science behind this phenomenon and provide a definitive answer to this perplexing question.
The Coriolis Effect: A Global Force
The Coriolis effect is a fascinating phenomenon that influences the direction of moving objects on Earth. It is caused by the Earth’s rotation and deflects objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
Does the Coriolis Effect Affect Toilet Water?
The Coriolis effect does have a very minor influence on the direction of toilet water as it flushes. However, the effect is so small that it is virtually unnoticeable to the naked eye.
Factors Affecting Toilet Flush Direction
The direction of toilet water flow is primarily determined by the design of the toilet bowl, the shape of the drain, and the initial force of the flush. The Coriolis effect plays a negligible role in comparison to these factors.
Toilet Bowl Design
The shape of the toilet bowl can influence the direction of the flush. Bowls that have a clockwise spiral design in the Northern Hemisphere and a counterclockwise spiral design in the Southern Hemisphere can create a slight vortex that influences the water’s direction. However, this effect is still very subtle.
Drain Shape
The shape of the drain hole can also affect the direction of the flush. Drains that are slightly oval or elongated can create a slight asymmetry that influences the water’s flow.
Initial Flush Force
The initial force of the flush can also affect the direction of the water. A strong flush can create a powerful vortex that overrides any minor influences from the Coriolis effect or the toilet bowl design.
Myth Debunked
Based on the scientific evidence, it is clear that the toilet water in Australia does not flow backwards. The Coriolis effect has a negligible influence on the direction of the flush, and the primary factors that determine the water’s flow are the toilet bowl design, drain shape, and initial flush force.
Why the Myth Persists
Despite the scientific evidence, the myth that toilet water flows backwards in Australia persists for several reasons:
- Optical Illusion: The swirling motion of the water during a flush can create an optical illusion that makes it appear to flow backwards.
- Confirmation Bias: People who believe the myth may be more likely to notice and remember cases where the water appears to flow backwards, while ignoring cases where it flows in the opposite direction.
- Cultural Beliefs: In some cultures, it is believed that the Coriolis effect has a stronger influence than it actually does, leading to the perpetuation of the myth.
In a nutshell: Unraveling the Mystery
The question of whether toilet water in Australia flows backwards has been thoroughly investigated and debunked. The Coriolis effect has a negligible influence on the direction of the flush, and the primary factors that determine the water’s flow are the toilet bowl design, drain shape, and initial flush force. Therefore, the myth that toilet water flows backwards in Australia is scientifically unfounded.
Questions We Hear a Lot
1. Why does my toilet water sometimes swirl in a different direction?
The direction of the swirl can be influenced by factors such as the design of the toilet bowl, drain shape, and initial flush force. It is not necessarily an indication of the Coriolis effect.
2. Is the Coriolis effect stronger in Australia than in other countries?
No, the strength of the Coriolis effect depends on the latitude and not the country. It is slightly stronger in Australia than in countries near the equator but the difference is negligible.
3. Can I use the Coriolis effect to predict the direction of the toilet flush?
No, the Coriolis effect has a very minor influence on the direction of the flush and cannot be used as a reliable predictor.
4. Why is the myth that toilet water flows backwards so persistent?
The myth persists due to optical illusions, confirmation bias, and cultural beliefs.
5. Is there any scientific evidence to support the myth?
No, there is no credible scientific evidence to support the myth that toilet water flows backwards in Australia.
