Many people are unaware of the true function of these two toilet buttons.

Modern toilets often come with dual flush buttons, but many people don’t fully understand their purpose. These buttons help conserve water: the larger button uses 6-9 liters for solid waste, while the smaller one uses 3-4.5 liters for liquid waste. By choosing the correct button, households can save up to 20,000 liters of water per year compared to traditional single-flush toilets. While the initial installation may be more expensive, it’s beneficial for both the environment and your water bill. The idea, first introduced by Victor Papanek in 1976, was implemented in Australia in 1980.
