Water is becoming scarce due to the ever-growing population. We waste several thousands of gallons of water every day without even knowing it. For instance, a conventional toilet uses 5-7 gallons of water during a flush and since an average person flushes more than 5 times a day, it adds up to 30 gallons of water per day.
The solution to this problem comes with dual flush toilets. They consist of two flush buttons that send down water with twice the intensity and clear all types of waste in one go.
It eliminates the need to activate a second flush, thus saving gallons of water every year. It is important that you pick the best dual flush toilet to enjoy all the benefits they have to offer.
You can save about 13,000 gallons of water every year by merely changing your toilet, according to a report published by the EPA (the United States Environmental Protection Agency).
So without much ado, let’s have a look at some of the best dual flush toilets on the market:
