The smaller flush uses only.8 gallon of water, and the bigger flush uses only 1.8 gallons, meaning this toilet meets the new standard for best high efficiency toilets via http://www.watermatrix.com/products/
New, standard toilets use 1.8 gallons with every flush, so by using this dual flush toilet, you could save thousands of gallons per year!
Installing and using HET toilets can add green building points if you are wanting to achieve LEED green building certification.
Although this high efficiency toilet reduces water consumption, it is still a high quality toilet that doesn’t stop up easily. This toilet has some serious flushing power that can be put to the test against standard toilets.
Because this toilet’s flushing action is different that standard toilets, it does a better job of cleaning out the bowl with much less water. It works by using a “wash down” style of flushing rather than relying on gravity suction. This way, the bowl of the toilet is evenly rinsed using much less water.
Another bonus of this toilet is that it makes much less noise because there is less water and lower volume. Not only is the flushing quiet, but the inlet valve used to refill is also very quiet, as well. Flush buttons and accent pieces come in best quality.
