On your water meter, there is a small red triangle shaped piece on the dial that is a low flow indicator. It will rotate if there is any flow through the meter. It is useful when checking for leaks. To check for leaks, shut off all the water flow in the house, such as faucets, washing machines, ice makers, etc. Watch the red triangle for at least 15 minutes. If it moves there is flow through the meter and you have water running somewhere. Another way to check for leaks is to write down the numbers and the location of the dial indicator. Do not use water for 2 hours. After the 2 hours read the meter again. If the dial has moved you may have a leak and need to repair or contact a plumber as soon as possible for assistance to avoid a high water bill.
