Last month, my water bill was about $500. I checked the meter and found the spinner was running at various speed. Sometimes, it was running quite fast and at the next second it would slow down, then speeding up again. This all happened when there was no water usage. I thought a leak would cause the meter to run at constant speed, not up and down. True?
This is not about where the system leaks but meter behavior. I have hired a plumber to dig and install valves in many places. Yet, he couldn't find the leak.
