High Water Bill? Water Meter Leak Detection

A Cobb County Water System bill that climbs with no visible leak is one of the most common reasons people call us in Smyrna. A slab leak stays under the floor. A silently leaking toilet flapper runs into the bowl and down the drain unnoticed. Your water meter registers every gallon passing through whether or not you can see where that water went, making it the fastest, cheapest diagnostic step before we ever send a truck.

Run the Test Yourself, Right Now

Turn off every fixture and appliance that uses water, including anything on an automatic cycle like an irrigation timer. Find your meter, note the reading, wait at least two hours without using any water, then read it again. Any movement means water left the system somewhere between the meter and your fixtures, even with everything off.

Fast Flow vs. Slow Flow

A fast, steady flow points toward a supply side leak, a slab, yard, or service line failure running continuously. A slower or intermittent flow more often points toward a fixture, most commonly a silently leaking toilet flapper, which can waste hundreds of gallons a day without ever overflowing or making a sound. A bill that has been high for several cycles usually means a smaller, slower leak rather than a sudden failure.

Common Causes Behind a High Bill

Slab leaks are common in Smyrna's mid-century concrete slab homes, see our slab leak page. Silent toilet leaks are next most common. Food coloring in the tank showing up in the bowl within ten minutes confirms it. Once you have confirmed loss with the meter test, we combine that flow rate data with acoustic listening and thermal imaging to pinpoint exactly where the water is going.
