We recommend that customers take the first reading before they go to sleep and then the second when they wake up (before using any water). The two readings should be the same if no one has used water in the house for several hours. If the readings are not the same, you probably have a leak.
There is also a small triangle or diamond on the face of the water meter known as the fine flow indicator. During the meter inspection while all of your water appliances are off, the indicator should not move. If the indicator is moving then this means that water is going through the meter and into the house.
Remember: humidifiers, refrigerator units, ice makers, toilets and all water softeners use water. If these items are in use, water will pass through your meter and affect the reading.
