∑ 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 wheel that rotates when water is flowing through the meter. If the dial is moving, you may have a leak.
Or, you can also take a meter reading and wait 2 hours and take another meter reading (make sure no water is used during this time). If the reading has changed, you may have a leak.
∑ Walk through your house listening for running toilets and looking for drips.
∑ Find out if your toilet is leaking silently by placing a drop of food coloring in the toilet tank. If color shows up in the toilet bowl after 10 minutes without flushing, you have a leak. Once you finish, flush a few times so you donít stain the toilet.
