Editor’s Pick: Top 10 Best Dual Flush Toilets in 2022

Dual Flush Toilets are designed with two types of levers. These modern-day toilets use a unique mechanism that involves using two buttons or levers, which, on pressing, release different amounts of water. Both of these buttons are connected to their respective exit valve.

The main aim of a dual-flush toilet is the conservation of water. Around 30′ of the total consumed water is used while flushing. This amount is much more than the required for any other household chore.

A full flush in a dual flush toilet lets out around 6 liters of water in one flush. At the same time, a half flush releases only 3 liters of water in one flush. Hence, every time you use the half flush button, 3 liters of water is saved. In total, a person can save up to 24 liters of water each day by using this mechanism.

Victor Papanek initially introduced this concept in his book called ‘Design for the real world.’ This technique first came into usage in Australia in 1980.
