According to the Environmental Protection Agency (EPA), toilets account for nearly 30% of the indoor water consumption in an average home, making them the main source of water use. But gone are the days when this throne unnecessarily guzzled gallons and gallons of water. Innovations like gravity-fed and pressure-assisted flushing ensure a complete flush with far less water usage.
The maximum allowable toilet flush volume (also known as gallons per flush, or GpF) in the U.S. is 1.6 GpF. For a toilet to earn the EPA's WaterSense label, it must use no more than 1.28 GpF. And there are effective and efficient toilets on the market today using even less water.
According to the EPA, if all of the old, inefficient toilets in the U.S. were replaced with WaterSense models, we could collectively save 360 billion gallons of water annually.
And the big question... will a single flush still do the trick? Yes! Today's toilets are effective and efficient. With enough oomph to flush more than a normal amount of waste while using less water than it takes to boil pasta, it’s easy to go with the flow.
