Make sure no one in the house is using water, like dishwashers, showers or washing machine. Go out to the meter and shine a flashlight on it (regular light, not LED) Most homes are now equipped with a new electronic meter that is solar powered. If you see an image of a drippy faucet appear, this indicates a leak between the meter and.your home or business. On an older style meter, there may be a small pea size circle with a blue or red triangle on it. Watch this triangle for 5 to 10 minutes and if it moves, you have a leak. If no triangle is present, simply see if any of the numbers on the dials change. This also indicates a leak.
