Home Leak Detection


In this video PSA we help you understand your water meter and how to detect if you have a water leak.



  1. A good practice when you go away from home for extended periods of time is to close off your incoming service valve before you leave. Having your own shut off valve installed on your side allows you to turn water on and off to your property.
  2. Watch the face of your assigned water meter and see if the little triangle (your leak indicator) or dial in the meter moves. Wait for about 2 minutes. If it moves then you have a leak.
  3. Request GWA to unlock your meter box so that you can observe the leak indicator on the face of the meter.
  4. Close off your incoming service valve right away. Also, make sure you have your own shut off valve installed on your side so you can turn water on and off to your property.
  5. Turn off all noises in house such as air conditioner and other appliances. Listen for any water that might be hissing, or gushing. That’s a leak.
  6. Check hot water heater which is often a source of leaks. Place palm on surface of floors and walls for temperature changes on surface.
  7. Look for water accumulation (ponding) or accumulated weed-grass-brush growth. Or areas around your home that may have algae or other green growth around it. Especially during a dry spell.
  8. Check your toilet tank. Drop some food coloring in the toilet tank and observe the toilet bowl. When you see the water in the toilet bowl turn the color you dropped in the tank, you have a toilet leak.
  9. Check your water lines. That is those lines that come into your house from the meter. Those lines are your responsibility to fix not GWA’s.
  10. Check the consumption on your water bill. Ask the GWA customer service division to run a data control log on your account. If it goes up suddenly you may have a new leak or if it goes up just a little every month you could have a small leak which could get bigger.
