How many gallons of water does an average 10 minute shower use?
If your house was built in (<1980 is 5-7, 1981-1991 is 3.5, 1992> is 2.5) the standard flow for showerheads then was 5-7/3.5/2.5 gallons per minute. Today many high quality showerheads are available, which have a maximum of flow of 2.5 gallons per minute. Replacing old showerheads with new ones can save you as much as 750 gallons per month. (Example – 10-minute shower at 5 gallons per minute is 50 gallons of water used per shower. A 10-minute shower at 2.5 gallons per minute is 25 gallons of water used per shower. 50 gallons x 30 days = 1500 gallons, 25 gallons x 30 days =750 gallons, which is a 750 gallons of water per month savings). http://www.hiddenvalleylakecsd.com/watertip.
