Locate your water meter and check the leak indicator to see if it is moving. Depending on the brand of your meter, the leak indicator could be a small triangular shaped dial or a small silver wheel that rotates when water is flowing through the meter. If the dial is moving, chances are, you have a leak.
Or, you can also take a meter reading and wait 1 or 2 hours and take another meter reading (make sure no water is used during this time). If the reading has changed, you have a leak.
There are several undetected ways through which water manages to leak out. A leakage need not be a large one. Even the smallest leaks if left ignored for long, can lead to severe damage to the structure of the building. Such leaks can be found inside construction, behind walls, under concrete slabs and asphalt of a building. Sometimes, drains, landscaping and fountains also experience leakages and can go undetected for a long time. If at any time you experience that a water body containing water around your building seems to be losing out on water at a more than the reasonable rate or that a space that should not be moist shows signs of moisture, there is a very good chance there is an underground water leakage.
