I had wondered that too. If I turn off the mains (where the water main comes into the house - not at the city boundary) the noise stops. I figure based on that, the leak was somewhere inside the house and not outside the house. I don't know if that's a sound assumption to make or not though. Short of digging up the yard out to the city shut off, I'm not sure what I can do to test on my end. I've read that some specialty plumbers have sonar equipment that can detect these leaks. That might be my best bet.
Sure, shoot me the number of the plumber if you can find it. Thanks!
