The Myth of Lid-Closing During Toilet Flushing: Debunked

Have you ever wondered whether closing the lid when flushing a toilet really helps prevent splashing? Some believe it does, while others dismiss it as a mere myth. This article delves into the mechanics of toilet flushing, the potential risks associated with a lidless flush, and real-world examples that challenge the notion of lid-closing's effectiveness.

The Science Behind Toilet Flushing

To understand the debate, it is essential to comprehend the science and mechanics of toilet flushing. Modern toilets use a siphonic action to clear the bowl efficiently. When the tank empties, the water and waste are pushed down the bowl with force, creating a fine mist of water and particles. This mist is often referred to as a toilet plume.

Health Risks of Toilet Plume

According to Dr. Oz, closing the toilet lid before flushing can minimize the risk of splashing and the spread of bacteria such as E. coli. These bacteria can be harmful if they come into contact with surfaces or open wounds. In fact, seating your face near the flushing scene can expose you to respiratory pathogens.

Real-World Experiences and Observations

First-hand observations suggest that the effectiveness of lid-closing can depend on the type and model of the toilet. In New York City, for instance, the toilets often have extremely powerful flushing speeds, which can create a mist similar to Niagara Falls. This experience supports the myth that lid-closing is indeed necessary to mitigate the splash.

Stepmother, a former health inspector, adds to the validity of the myth by emphasizing the risks associated with toilet plume. She explains that the more powerful the flush, the higher the likelihood of a toilet plume, which can carry contaminants into the air.

The Debate Continues

While some believe that closing the lid prevents any splashing, others argue that the results may vary. According to Pee Guy, the effect may be negligible in modern toilets that use less water but have more powerful flushing mechanisms. Additionally, the act of closing and opening the lid can introduce air into the toilet bowl, potentially exacerbating the situation.

Some suggest that keeping the toothbrush and other personal items away from the toilet is a better solution. Pewit Tinto, a health enthusiast, recommends storing such items in a medicine cabinet or other enclosed space to minimize the risk of contamination.

Conclusion

The debate over whether closing the lid when flushing a toilet is a myth or an effective practice is far from settled. While anecdotal evidence and health inspector validations suggest that it does help in reducing the toilet plume, the study’s results can vary based on the specific toilet model used. As with many customs, what works in one situation may not work in another. For now, it seems that closing the lid is better safety practice, especially in situations where a powerful flush is a factor.
