Modern dual-flush toilets are often misunderstood, with many people thinking the two buttons are merely decorative.
However, these buttons are designed to save water: the larger button is for solid waste, using 6-9 liters of water, while the smaller button is for liquid waste, using 3-4.5 liters.
When used properly, dual-flush toilets can help households save up to 20,000 liters of water each year compared to traditional single-flush systems. Though initially more costly, this system, introduced in Australia in 1980, benefits both the environment and household finances.
