If you suspect a leak, track your usage on each billing statement. Look for abnormal increases. (Note: Most people use more water in the summer than the winter when watering the lawn, filling pools, etc.)
Make sure no water is being used inside or outside of your house. Next locate your meter and check the flow indicator to see if it is moving. Or, you can take a meter reading and wait 1 or 2 hours and take another meter reading (make sure no water is used during this time). If the reading has changed, you have a leak.
After you have determined that you have a leak, the next step is to determine if the leak is inside or outside of your house.
Turn off the water at your shut-off valve. If you do not have one, turn off ALL water-using fixtures: toilets, faucets, dishwasher, washing machine, ice maker, etc.
Check the flow indicator: if it stopped spinning or if there is no symbol on the digital meter, the leak is likely inside your home.
If it is still spinning or if there is an arrow and plus symbol on the digital meter, the leak is likely outside between the meter and your house.
Things you can check:
- Running toilets
- Dripping faucets
- Check the yard from the meter to the house for soft or greener areas
- Water lines under the house
