Dual Flush Toilets Are Newest Way to Save Water

    NEW YORK, April 16 /PRNewswire/ -- Long showers or leaving the water
 running while brushing your teeth may be thought to be the most wanton
 waste of water, but the real guzzler of the house is the toilet. Each
 household member flushes the toilet four or more times daily on average,
 accounting for more than 20 gallons per person. If the toilets in the house
 were installed before 1994, they account for 40% of the household's total
 use of water.
     Today, homeowners have options to save water. In fact, there are two.
 Caroma, an Australian company, has dual flush toilets that feature two
 buttons: one for liquid waste, the other for solid waste. It works on the
 theory that less water is needed to rid the bowl of liquid than solids. The
 buttons provide a direct-to-the-consumer means to further conserve water
 each time the toilet is flushed. Choose to use either .8 gallons or 1.6.
 The average of the two - .95 gpf - makes a dual flush model the most water-
 conscious toilet on the market today.
     It is a brilliantly plausible concept made effective by redesigning the
 flushing technology and enlarging the trapway to nearly double that of the
 industry average. The look of Caroma toilets is similar to traditional
 toilets, but inside they function on a unique principle which has allowed
 the brand to develop a worldwide reputation as the water-saving toilet that
 is nearly impossible to clog.
     There are an estimated 100 million toilets in the US still guzzling 3.5
 to 7 gallons of water each time they are flushed, well above the 1.6
 maximum set by the National Energy Policy Act for toilets sold after 1994.
 The initial rush by domestic manufacturers to comply with the mandate for
 low flush toilets (LFTs or ULFTs, as they are called) resulted in a spate
 of toilets that did not perform well. Multiple flushes were often
 necessary, negating the water savings, and early models were plagued with
     Today's marketplace is eager to conserve water, but demands efficiency
 in performance, too. The latest plumbing lingo now includes HET and MaP. An
 HET, high efficiency toilet, has an even higher standard in water usage,
 reducing flow to 1.28 gallons per flush. All HETs are scored for flushing
 efficiency. The MaP (Maximum Performance) score is the best measure yet of
 a water saving toilet that functions effectively.
     Dual flush technology is now the prevailing technology all over the
 world, just not yet in North America. But, consumers here are starting to
 learn about the two button toilet from Down Under, which puts the household
 toilet way down the list in the water-waster category, well behind the
 washer, faucets and shower, even short ones.
