Outside the Home
Check around the house and yard for any very green or wet spots.
Check your sprinkler system. Broken heads only leak when the system is operating, but they don’t usually add a lot of water usage unless they are turned on. A broken pipe in the system leaks regardless if it is turned on or off, and can add many more gallons to the usage.
The best place to detect a leak is at the water meter outside. If all the faucets are turned off inside the home, upon the request a meter reader can observe the meter dial hand and note its movement over the span of 3-5 minutes, if the dial hand does not move, there is no leak.
If the dial hand moves, that indicates a possible leak. The meter reader will not be able to determine the origin of the leak. You may need to call a licensed plumber at that time.
