Check all the faucets in your house for leaks. A single dripping faucet can waste more water in one day than a family member would need for drinking in a whole week! Is it possible that a toilet has a silent leak? Even a small leak of about two tablespoons a minute adds up to 15 gallons a day…or 105 gallons a week and 5,460 gallons a year down the drain! Be a leak detective.
