Water meter running when nothing is on? Here's Who to Call
If your water meter keeps spinning even when every faucet, toilet, and appliance is off, you likely have a hidden leak. Underground slab leaks, pinhole corrosion in copper lines, or a silently running toilet flapper can waste thousands of gallons a month and cause structural damage before you ever see a puddle. A licensed plumber can perform a pressure test, use electronic leak detection equipment, and pinpoint the exact location without tearing up your home.
