The Mystery of the Dual Flush Toilet: Why Two Buttons?
Have you ever wondered why modern toilets have two flush buttons—one smaller than the other? They are called “dual flush” toilets, and there’s a good reason for having that choice. Let’s dive into the exciting world of toilet design and find out why!
What is Dual Flush?
In today’s bathrooms, most toilets come with two buttons or levers. Each button is linked to a different exit valve, and one is bigger than the other. But why? The answer is simple: it’s all about saving water.
“The smaller flush uses less water, while the larger flush handles the heavier stuff,” explains bathroom design expert Sarah Richards.
This design allows us to choose how much water we use depending on what we’re flushing. The larger button uses around 6 to 9 liters of water, while the smaller one only uses about 3 to 4.5 liters. So, if you’re just flushing liquids, you can use the smaller amount of water. But if it’s time for something more solid, you hit the larger flush. It’s that simple!
How Much Water Do You Actually Save?
Switching to a dual flush toilet can save a lot of water—up to 20,000 liters per year! Imagine that: every year, your household could save enough water to fill a whole swimming pool just by choosing the right flush.
Not only is this great for the environment, but it also helps you save on your water bills. Sure, the installation might cost a bit more than a regular toilet, but it’s an investment that keeps paying off over time.
“Saving water is one of the easiest ways to help the planet,” says environmentalist Emily Hayes. “With a dual flush toilet, you’re making a difference every day, without even trying.”
How Did It All Start?
Believe it or not, the idea of the dual flush toilet came from a famous American designer named Victor Papanek. In his 1976 book, Design for the Real World, he introduced the concept of toilets that could flush different amounts of water depending on the need. It wasn’t until 1980 that Australia became the first country to adopt the dual flush system, and it quickly spread around the world.
“Good design should always consider how it impacts the environment,” Papanek wrote. His forward-thinking ideas have since changed the way we think about bathroom efficiency.
How to Use the Dual Flush Toilet Like a Pro
Next time you’re in the bathroom, try becoming a water-saving expert! If you only need to flush liquid waste, press the smaller button. This button is often marked with a symbol, like a small circle or a raindrop.
It’s a visual reminder that it’s meant for light flushing. If you need to flush solid waste, go for the bigger button—it’s usually bigger or clearly marked with something like a full circle to indicate it uses more water.
“It’s a simple choice,” says bathroom designer Mark Fisher. “You just need to think about what you’re flushing, and you’ll be making the right decision for both your wallet and the planet.”
