Check Your Water Meter: The easiest way to check if you have a leak is to look at your water meter, normally located outside your home. If you don’t know where it is, call your local utility department and they can help you. When you check the meter, make sure no one is using water in your home. Then view the leak indicator dial on the water meter that indicates a leak is occurring.

Determine if the Leak Is Indoors or Outdoors: Turn off the main water valve in your home. Normally this is in your basement or garage, or sometimes outside by an outdoor water faucet. Then check the water meter and leak indicator again, making sure that no one uses water inside or outside your home during the test.
