Okay, here is where we are today. I found the house main cut-off and turned it off. When I do that, the meter stops running. I wasn't expecting this, I really thought I would find a leak in the ground between the city main and the house main.
No toilets are running, I shut them off and the meter still crept. I turned off the HW heater, didn't do anything (the drain was dry anyway...200Gallons a day, it would be noticable.)
Well...I will keep trucking, certainly interesting.
