| In the early days of 1.6 gallon toilets, some homeowners were having to flush three or four times or continually unclog their new toilets; giving the name ‘ultra low flush’ a bad reputation. By the late 1990’s new designs improved performance dramatically. Since then manufacturers have responded to the demand for a better looking toilet that saves even more water by introducing the first High Efficiency Toilet functioning at 1.28 gallons per flush. Today these new toilets are as good as or better than the 1.6 gallon toilets of today. Performance testing by the California Urban Water Conservation Council found that new HET models use less water and remove more waste than older 1.6 gallon models.
HETs are available at local plumbing stores; just tell them you want a toilet using an average of 1.28 gallons per flush or less.
There are three types of HETs:
1. Single flush - 1.28 gallons per flush
2. Dual flush - 0.8 gallons per flush for liquids and 1.6 gallons per flush for solids (averages 1.28 gallons per flush)
3. Pressure assist - 1.1 gallons per flush (recommended for commercial use due to louder flush).
With the district retrofit credit along with money saved on your water bill, the toilets usually pay for themselves in less than two years.
