Our water meter is in the basement. We had a leak in our line between the shut off and the house which is our responsibility for repair but the leak didn't go through the meter so we weren't responsible for the lost water.
Keep bugging the water works to replace the meter. If you have a licenced plumber that says there are no leaks they should listen.
The same guy from the city witnessed the meter run the first time and not run the second time . He said the leak didnt fix itself but couldnt explain why it is happening. I just dont want to deal with a sporatic meter in the future
