Check your water meter when there is no usage. Most meters have a small triangular mechanism on the meter face that should be perfectly still. If it is gently rocking or turning it is an indication that there may be a small leak in the house. Check your water meter reading before going to bed and read it when you wake up, to make sure no water is leaking that you’re not aware of.
If you do find the meter reading has changed, check for leaks in your home. Put a few drops of food coloring in your toilet tank and wait 15 minutes. Check the bowl-if the dye has seeped into the bowl you have a leak, and need to replace the parts in the tank. Read your meter again the following morning.
The difference between the 2 morning readings is the amount of water used in a day, but it is measured in cubic feet. Take the amount of water used and multiply it by 7.5 and you will know how many gallons your household used. Water use habits vary, but the recommended amount of water per person per day is 62 gallons or less.
