-Turn off all water in and outside of your house. DO NOT TURN OFF THE MASTER VALVE.
-Record the reading on your meter.
-Do not use any water in your home for at least 1 hours.
-Recheck the meter every 20 minutes for 1 hour. The reading should be identical to the reading taken earlier. If it is higher, you have a leak.. It is your responsibility to have it repaired.
NOTE: Continuously running toilets can be a silent culprit. Check the overflow pipes in the toilet tanks to be sure water isn't draining. Place a few drops of food coloring in the tank, don't flush and check the bowl in about 15 minutes. If any of the colorings appear in the bowl, you probably have a tank to toilet bowl leak, which will require a repair.
