Inside the meter box is a meter with a row of numbers. A customer is billed for every 1,000 gallons used. Starting on the left side of the numbers, the first four digits is the current reading the City would use for billing. These numbers can help you determine if you have a leak from the meter to your home.
With no water fixtures running, the last digits should not change or a red dial should not move. However, if either one of those two things move after a couple of seconds, you may have a leak. Generally a running toilet, a dripping faucet or a leaking irrigation valve are the most common issues.
Private leak detection companies can locate your leaks. The City does not locate leaks on private water systems.
