Trying to reduce your household water consumption? Look no further than your toilet, the number-one water guzzler. One of the all-time thirstiest fixtures, toilets are estimated to be responsible for upwards of 30 percent of household water consumption. And those predating the 1992 federal restrictions of 1.6 gallons per flush (gpf) are especially inefficient. Thanks to technological advances, a new breed of toilets offers increased efficiency and performance (early adopters may still wince at the less-than-stellar flushing capabilities of the first low-flow models). Replacing an older model with a high-efficiency
WaterSense-certified toilet will reduce water consumption and lower your costs.
We’ve singled out seven notable toilets that meet EPA flushing guidelines of 1.28 gpf or less, and use at least 20 percent less water than the celebrated 1.6 gpf models. This is especially important if you live in California, which now limits toilets sold in the state to the 1.28 gallons per flush standard.
