Many people still assume these two buttons are solely for flushing

Many people still believe that the two buttons on modern toilets are just for flushing, but dual flush toilets offer much more than that. These toilets feature two separate flush options: a smaller one for liquid waste and a larger one for solid waste. Each button is connected to its own exit valve, allowing users to select the flush that matches their needs. The smaller flush uses around 3 to 4.5 liters of water, while the larger one releases 6 to 9 liters, making it a simple way to conserve water without sacrificing performance.

Switching to dual flush toilets can save a household up to 20,000 liters of water per year compared to single-flush models. While the initial installation may cost slightly more, the long-term benefits include lower water bills and a reduced environmental footprint. The concept was first proposed by American designer Victor Papanek in his 1976 book, Design for the Real World, and Australia began implementing dual flush toilets in 1980.

Today, this design is used worldwide, promoting both efficiency and sustainability. To use these toilets effectively, pay attention to the visual cues on the buttons. The smaller lever, often marked with a half-circle or small raindrop, is for liquid waste, while the larger button, typically a full circle, is for solid waste.

By making the right choice each time, you not only save water but also help the environment and reduce utility costs. A small action, like pressing the correct flush, can have a meaningful impact over time. Dual flush toilets are a simple, effective, and eco-friendly solution for every home.
