Detecting a Leak

To help conserve water and reduce waste on your property, SCWA encourages all customers to regularly check for leaks. Here are some tips to help you get started.

Follow these quick Steps

  • Turn off all water inside and outside of the house, including showers, sinks, the washing machine, and any appliance that uses water.
  • Take the lid off the meter box.  Be careful, as lids can be heavy, and sometimes bugs and small animals hide inside meter boxes
  • Watch the meter
  • Shine a light onto the water meter to wake up the LED screen.
  • Check to see if the leak indicator is on (The leak indicator is a picture of a faucet). If leak indicator is showing a picture of a faucet, the water meter is potentially detecting a leak that is located past the water meter.
  • Locate the main shut-off valve in your house.  It is usually located near the hot water heater in the basement, garage, or crawl space.
  • Turn off the valve.
  • Turn on a faucet inside the house to test.
  • If water still flows from the faucet after several seconds, the shut-off valve is not working.  There is no way to tell if the leak is indoors or outdoors.
  • If no water flows through the faucet, the shut-off valve is working.  Return to the meter.
  • Check if the meter’s leak indicator is on (The leak indicator is a picture of a faucet).
  • While having the shut-off valve at the house closed, if the leak indicator is showing a picture of a faucet and the gallons number is increasing, the water meter is potentially detecting a leak that is located between the water meter and the shut-off valve. That means you have an underground leak.
  • While having the shut-off valve at the house closed, if leak indicator is showing a picture of a faucet and the gallons number is not increasing, the water meter is potentially detecting a leak that is located indoors.

The most common type of water loss is through a toilet malfunction.  To test your toilets, place water base food coloring or dark liquid in the backside of the toilet tank.  Wait approximately 45-60 minutes and check the toilet bowl.  If the water in the bowl has started to change colors, then you have what is known as the silent leak in your toilet.
