How to tell if you have a leaking pipe
Wait until everyone is finished using the water for the evening (showers, toilets, dishwashers, etc). Locate your water meter which is normally just outside the front boundary of your property and most are covered by a green lid that will be flush with the ground. Open the lid (you may need a small screwdriver to pry the lid open) and you will see a small lever handle at one end and a water meter in the middle. Write down the meter reading on a piece of paper. Ensure nobody uses the water till morning when you check the meter again and write down number again. If the morning figure is higher then it is quite probable that you have a water leak that needs to be located and repaired as soon as possible.
