How do I determine whether I have a leak?
Make sure all the water in your home is turned off (no washing machine or dishwasher running). Go to your water meter in the ground, remove the lid and see whether the dial is moving. If the dial moves at all, and you are sure no water on your property is on, then there is a leak in your plumbing, or between the meter and your home. If you have a crawl space, be sure to check there as well.
