Step 3: Multiply the answer from Step 2 by 365 — this gives the number of ounces per year leaking through the faucet.

384 ounces per day X 365 = 140,160 ounces per year

Step 4: Divide the answer from Step 3 by 128 — this gives the number of gallons per year leaking through the faucet.

140,160 ounces per year ÷ 128 = 1095 gallons per year

That’s a lot of water! And it took a lot of energy to make it hot. You can figure out approximately how much oil, or gas, or electricity was wasted by doing the following calculations:

For an oil fired hot water beater: Divide the answer from Step 4 by 110 —this gives the approximate number of gallons of oil wasted.

1095 ÷ 110 = 9.95 gallons of oil per year.

For a gas-fired hot water beater: Multiply the answer from Step 4 by 1.2 —this gives the approximate number of cubic feet of gas.

1095 X 1.2 = 1,314 cubic feet of gas per year

For an electric hot water heater: Multiply the answer from Step 4 by 0.25 —this gives the approximate number of kilowatt-hours of electricity wasted.

1095 X 0.25 = 274 kilowatt-hours per year
