Modern-day toilets come with two types of flushes, one is smaller than the other. They are called ‘dual flush’ toilets but ever questioned why are you given that option? We tell you.

The modern-day double flush toilets come with two different types of buttons. One is larger, while the other is smaller and each button is connected to its own exit valve.

The larger lever is to flush out around 6 to 9 liters of water, whereas the smaller lever is to flush out around 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.

It has been calculated that if a family adopts the practice of dual flushing, it can save up to 20,000 liters of water in a year when compared with single flushes. Though the fitting may cost you a little more than the normal flush, it is eco-friendly and helps cut down on water bills.

The dual flush concept is the brainchild of American industrial designer Victor Papanek, proposed by him in his book ‘Design for the real world’ in 1976. It was first implemented in Australia in 1980.

So, the next time you use the toilet, flush as per your need. If you only urinate, go for the smaller lever. It can either be small in size or will have an image, such as a half or small circle or a small raindrop, indicating that it is the small flush. If you go to take a dump, only then you must press the larger lever, which again will either be bigger in size or have visual indicators.
