"Toilets must meet criteria in the following areas to be considered water efficient: 1) effective flush volume shall not exceed 1.28 gallons 2) solid waste removal must be 350 grams or greater 3) the toilet must conform to the adjustability and other supplementary requirements. The WaterSense program was designed by the US Environmental Protection Agency to encourage water efficiency in the US through the use of a special label (which is featured above on the page) on consumer products. WaterSense-rated faucets and faucet accessories are high performing water efficient fixtures."
This is what I am setting out to find tomorrow. I will be limiting my choices to Kohler and American Standard brands because of their high consumer satisfaction ratings. They also manufacture toilets which meet the above criteria. I will update you tomorrow on my choice.
