Check for LeaksWater leaks cost money. If you have a leak, have it repaired as soon as possible as your water meter measure all water used, even the drips. You are charged for the amount of water you use so the repair of small leaks will save you money.

To detect if there is a leak that requires further investigatin in your home you can use your water meter. 

Turn off all water fixtures in your house, including items such as humidifiers, air conditioners, and ice makers. Next, watch the low-flow indicator (red or white triangle generally located in the middle of the meter). If the triangle is moving closckwise, you have a leak.

Numbers on the water meter can also indicate a leak. This is only useful if the number is checked in the evening when water is no longer being used and again in the morning before any water is turned on. If the numbers have increased (similar to a cars odometer) than you likely have a water leak.

Toilet leaks are the the most common water waster in a home. Most customers are surprised as to how much water can flow through a toilet without being noticed. The hard part is that leaks in your toilet are also difficult to detect.

To find out if you have a leak add some food colouring or old coffee to your tank. Wait about 30 minutes to an hour and come back and check the bowl. If the colour from the coffee or dye has seeped into the bowl, then you have a leak. If you have found a leak in your toilet contact a licensed plumber to make the repairs or visit your local hardware store from more information.

You should check your home for leaks every 6 months to save money and potential damage to your home.The most common place a leak occurs in your home is the toilet but other places to check for leaks in the home include: 
showerheads
faucets
hotwater tank
furnace humidifier
washing machine
sump pump (if it water powered)
refrigerator if it has an ice maker and/or cold water dispenser
dishwasher
boilers
water softener
pool/hot tub
sprinkler system
outdoor hose (check annually for leaks)

Besides the obvious leaking facet dripping make sure to look for water marks on the floor, walls, ceilings or signs of mould which can indicate indoor leaks. If you find these signs you could have a leak that needs to be fixed. Consult with a professional to determine a best plan of action.
