How can the water meter tell me if I have a leak?

Newer types of water meters have a leak indicator on the face of the dial; see the photo. It is a triangular or diamond-shaped indicator that revolves 354 times for every gallon of water that passes through the meter.

To check for leaks, look at the indicator when no one is drawing water. It should not be moving. If it is moving, check every plumbing fixture at the property, i.e., toilet, sink, outside sprinkler, washer, etc. Shut off the valves that supply each fixture, one by one, and check the indicator after each shutoff. When closing a valve stops the indicator from moving, or slows its movement, you have found the location of a leak. There may be more than one leak!Once the leak is repaired, check the leak indicator again and make sure all leaks are repaired.
