Modern toilets often feature dual flush buttons, yet many don’t realize their purpose beyond flushing. These buttons allow for water conservation: the larger button flushes about 6-9 liters of water for solid waste, while the smaller uses 3-4.5 liters for liquid waste. By using the appropriate button, a household can save up to 20,000 liters of water annually compared to single-flush toilets. Although the initial installation may be costlier, it benefits both the environment and your water bill. Introduced by Victor Papanek in 1976, the concept was first implemented in Australia in 1980.
