Meter close up Water use is measured by a meter which is usually located on the sidewalk in front of your home. The meter’s read dial is an effective tool for detecting blind or hidden plumbing leaks in single-family properties.

Detect Leaks with Your Home's Water Meter

If all water fixtures are not in use (ie. bath and showers, washing machines, irrigation, toilet flushing) and the dial rotates continuously in one direction even slightly, this could mean there is a leak somewhere on the property. Check your water meter before and after a two-hour period when no water is being used. If the meter dial does not read exactly the same, you probably have a leak. See our detailed instructions on how to read your water meter.

Hidden Plumbing Leaks

There are many causes for hidden plumbing plumbing leaks. If you can’t see dripping or a constant stream coming from a particular fixture, a good place to start looking is your toilets, the most common household leak. We can help you learn more about identifying leaks and provide standard toilet repair parts during a free in- home Water Wise Evaluation.

When Do I need to call a plumber?

  • When making repairs to leaks between the meter and the home or in the water supply line
  • If you suspect leaking on a large appliance such as the water heater or dishwasher
  • If you think you might have a blind leak and need help addressing it immediately, call a plumber right away.
