We noticed that we had standing water in our driveway and in our yard, even though there was no rain. We checked our meter to see if there was a leak and at first there wasn't. We checked back 30 minutes later, and still the dial had not moved. So, we turned off all the water applicances in our house, took a picture of the meter before we left for work then took a picture when we got back. The dial had moved....slightly. We now know we have a leak, our question is where is it coming from? What do we do to try to find the leak...do we call a plumber first, or do we call a sprinkler guy first (we have a sprinkler system). We just need a starting place and we don't want to tear up our whole yard to find a leak.
