This type of arrangement is known as Dual Flush. Modern toilets have 2 types of levers or buttons and both buttons are attached to the exit valve. The two buttons dis-engage valves at different heights in the flush tank. Usually, the smaller one has its exit valve at a higher level which gives a smaller discharge of water. The second button is connected to the lower exit valve and empties the complete tank.
In short, pressing the big button gives 6 to 9 liters of water, and pressing the small button gives 3 to 4.5 liters of water. Clearly, the larger one is to flush solid waste and the smaller one is to flush liquid waste. This is a smart way of water conservation.
According to the reports, if Dual Flushing is adopted instead of Single Flush at a house, then 20 thousand liters of water can be saved annually. You must have been surprised to hear this, but it is true. Though the installation may cost you a little more than the normal flush, it is eco-friendly and helps cut down on water bills. So, the next time you use the toilet, flush as per your need.
