The meter dial contains a leak detector indicator. This is a small, red asterisk to the left of the center of the dial. This indicator rotates, even when there are minute amounts of water flow. If all water-using appliances are turned off and not using water, the leak indicator should not be moving at all. If it is, there is a leak somewhere inside the home or building. It is the customer's responsibility to have leaks repaired unless the leak is within the meter itself.
