Switching to an ultra-low flush toilet is an effective way to make your home or office more water efficient. Ultra-low flush (ULF) toilets use no more than 1.6 gallons per flush (gpf) rather than 3.5 to 7 gallons of water used by other designs. That's why new plumbing codes are requiring ULF toilets to be installed in all new construction, bathroom remodels and additions and toilet replacements.
A flush toilet is a toilet that disposes of human excreta (urine and feces), by using water to flush it through a drainpipe to another location for disposal, thus maintaining a separation between humans and their excreta.
