Cost Of Leaks
One drip per second from a leaky hot-water faucet or shower-head sends about 175 gallons a month down the drain. That's cash down the drain!Show your whole family what a little drip costs.
Use a leaky faucet or adjust a kitchen sink tap (cold water, please) to produce a steady drip, drip. You need an 8-ounce measuring cup, plus pencil, paper and a clock.
Catch 10 minutes worth of drips in the glass. Let's say it's 3 ounces. Here's how to figure out how much energy you're wasting with that one little drip.
(1) Multiply the number of ounces by 6 to give the number per hour and then by 24 to give the total per day, 3 ounces x 6 x 24 = 432 ounces per day.
(2) To find the number of gallons per year multiply by 365 days and divide by 160 ounces in a gallon. 432 ounces per day x 365 days ~- 160 ounces = 985.5 gallons per year.
(3) To find the number of Btu used to heat the water you must first know the temperature of the tap water, before and after it is heated. Assume the tap water temperature when it enters the hot-water heater is 40°F, and 140°F after it is heated. The difference is the number of degrees for which energy is required to heat the water. To find^ the Btu required, multiply the number of gallons per year by 10 pounds (weight of a gallon) and by the 100F degrees difference. 985.5 gallons per year x 10 pounds x 100F degrees = 985,500 Btu.
