Today is the first day of Fix a Leak Week, the Environmental Protection Agency's nationwide effort to find and fix hidden water leaks in homes. Did you know the average home wastes about 10,000 gallons of water a year due to running toilets and drippy faucets? One way to find out if you're wasting water is to turn off every faucet, shower, washing machine, etc. Check your water meter, and then come back a few hours later -- if the meter reads the same, you're good to go. If there's a difference, you probably have a leak.
