Inside the Home
To check for toilets leaks, put a few drops of colored liquid (food coloring, Kool-Aid, soda, etc.) into the tank. Wait approximately 10-15 minutes. If color shows up in the bowl, you have a leak. Sometimes these leaks go undetected as they cannot be seen or heard. Oftentimes, replacing the flapper alone will fix most toilets.
If a toilet is "running," then there is a faulty flushing mechanism and it needs to be replaced.
Check faucets to see if they are dripping and check all exposed pipes for leaks.
Outside the Home
Check around the house and yard for areas that may be greener than the rest of the lawn or wet spots. These may be an indication of a water leak.
Automated irrigation system? Broken sprinkler 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. If automated, check the timer. During a power outage your timers can reset, causing your system to run continuously when you are not aware.
Hoses & Spigots
Watering with a water hose? Check the hose to make sure there are no large holes or slits allowing extra water to run out.
Check all outside spigots for leaks.
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 and note its movement over the span of 3-5 minutes, if the register does not move, there is no leak.
If the digital register 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.
