Pre-1994 residential and pre-1997 commercial flush toilets use 3.4 US
gallons (13 L) of water per flush (gpf or lpf). In 1992, the United
States Congress passed the Energy Policy Act of 1992, which mandated
that beginning in 1994 common flush toilets use only 1.6 US gallons
(6.1 L).[19] In response to the Act, manufacturers produced low-flow
toilets, which many consumers did not like because they often required
more than one flush to remove solids. People unhappy with the reduced
performance of the low-flow toilets resorted to driving across the
border to Canada or Mexico, or buying salvaged toilets from older
buildings.[20] Manufacturers responded to consumers' complaints by
improving the toilets. The improved products are generally identified
as high efficiency toilets or HETs. HETs possess an effective flush
volume of 1.3 US gallons (4.9 L) or less.[21] HETs may be single-flush
or dual-flush. A dual-flush toilet permits its user to choose between
two amounts of water.[22] Some HETs are pressure-assisted (or
power-assisted or pump-assisted or vacuum-assisted).
