How can I as a homeowner check for household leaks myself?

Some leaks are more obvious then others, such as dripping faucets and running toilets, however, others are not so obvious.  The easiest way to check for leaks is to look at your meter when no one is using water in the house.  On the top you will see a large sweep hand but you will also notice a small triangle.  The triangle is a low flow indicator.  When water is passing through the meter, regardless of the amount, that triangle will rotate.  If that triangle is spinning when no one is using water then you can be sure you have a leak somewhere.
