How the Water Meter can Help Find a Leak

Go through your house and make sure no faucets are dripping
Check each toilet carefully:
- You shouldn’t hear a sound
- You shouldn’t see water running into the bowl
Turn off everything that uses water in your house, like the clothes washer or dish washer.
Make sure you don’t have an outdoor faucet turned on to water plants or to use a sprinkler.
Now, go out to your meter register and open the door.
Look for the little red or blue triangle near the center of the dial. If it is stationery (not turning at all), then you do not have a leak. If it is turning, even a little bit, that means there is water running somewhere in your house or underground. If it is moving and everything is turned off, you have a hidden leak.
Next, find the main valve where the water pipe enters your house, and turn it off.
Go out to your meter again and look at the little triangle. If it is not moving now, but it was moving before, it means the leak is in your house somewhere.
If the triangle is moving now, it means the leak is underground, between the meter and the supply valve that you just turned off.
If that triangle moves and everything is turned off and faucets are not leaking, call your plumber.
