While it may not seem like a lot, a dripping water faucet can add up fast. One gallon is equal to 15,140 drops. Suppose a faucet drips 10 times in a minute. That adds up to 14,400 drips per day or 347 gallons per year. Now, that's only from one tap. If you had three doing this, that comes out to 1,041 gallons per year! If you have a dripping faucet, don't wait!
