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 valve is the part inside the tank of the toilet that moves the water into the bowl. Toilet flush valves come in different sizes from 2â to 4â depending on the manufacturing of the toilet.
