How Many Gallons of Water Does It Take to Flush a Toilet?
Toilets manufactured from the 1980s use 3.5 gallons per flush, and models manufactured before that use even more, between 7 and 5 gallons per flush. When you consider the typical individual flushes five times per day, this may account for a appreciable amount of water use, particularly in multiperson families.
Low-flush Toilets Preserve Water
Every toilet manufactured since 1994 utilizes a maximum of 1.6 gallons per flush. Some newer versions use as few as 1.28 gallons per flush. While early models utilized to draw complaints about their poor flushing capabilities, low-flush toilets now flush only as well as their old, water-wasting counterparts. Toilets account for almost one-third of all household water use, meaning a multiperson household can save several thousand gallons annually by changing to a low-flush toilet.
