Your Water Bill Jumped and You Don't Know Why: A Leak Checklist

Start with the meter, not the guesswork

The EPA's WaterSense program estimates that the average American household loses more than 10,000 gallons a year to leaks that go unnoticed, and that nationwide, household leaks waste more than 1 trillion gallons annually. A jump in your Calhoun Utilities bill with no obvious explanation, like a new appliance or a guest staying longer, is worth taking seriously rather than shrugging off.

The test costs nothing and takes fifteen minutes. Turn off every fixture and appliance in the house, including anything on a timer like an ice maker or irrigation system, then read your water meter. Wait fifteen minutes without using any water, and read it again. If the dial has moved at all, water is escaping somewhere between the meter and your fixtures.

Where to look next, in order

Toilets are the single most common source of a silent leak, usually from a worn flapper that lets tank water seep into the bowl continuously. Drop a few drops of food coloring into the tank and check the bowl after ten minutes without flushing; color in the bowl means the flapper is leaking.

After toilets, check under every sink for a slow drip at the supply line or trap, and check outdoor spigots and any irrigation system, which are easy to overlook and just as capable of running up a bill as an indoor leak.

If none of that turns anything up but the meter still moved during your test, the leak is likely somewhere you can't see: under a slab, inside a wall, or in the yard line between the meter and the house.

A number worth knowing before you call

A faucet dripping once per second wastes more than 3,000 gallons a year, according to EPA WaterSense data, and a showerhead leaking at just 10 drips a minute wastes more than 500 gallons annually. Those are small, fixable problems that add up fast, which is worth keeping in mind if you're tempted to live with a minor drip rather than fixing it.

Why hidden leaks take longer to find here

Gordon County's newer housing carries an unusually high share of hardwood, tile, and luxury vinyl plank flooring, a byproduct of Shaw and Mohawk both running major plants in Calhoun. Those materials hide a leak underneath far longer than carpet does, which is part of why the meter test matters more here than in a lot of towns: your own eyes may not catch a slab or under-floor leak until the bill already has.

A mistake worth avoiding with leak detection

Assuming a leak has to be dramatic to matter is a common and costly mistake. A slow leak that barely moves the meter dial can still run for months, and months of even a small continuous leak adds up to real money and, eventually, real damage if it happens to be under flooring rather than somewhere visible. The meter test doesn't care how small the movement is; any movement at all is worth investigating.

The other mistake is checking only the obvious spots, under sinks and around the water heater, and stopping there when the meter test still shows movement. If the visible fixtures check out clean but the meter keeps moving, the leak is somewhere you genuinely cannot see without equipment, and continuing to search visually just delays finding it.

Why acting on a small movement matters here specifically

Because Gordon County's newer housing carries so much hardwood, tile, and vinyl plank flooring tied to the local flooring manufacturing industry, a leak that would show up fast under carpet in another town can run quietly under a Calhoun home's floor for a long time. That's exactly the gap between what the meter test tells you and what your eyes can confirm, which is why a positive meter test result is worth acting on promptly rather than monitoring it for another billing cycle to see if it gets worse.

A seasonal note worth knowing

Irrigation systems are a common, easy-to-miss leak source specifically in the warmer months when they're actively running, and a cracked line or a stuck valve can waste a significant amount of water before anyone notices, since it's happening outside and often out of daily sight. If your bill jumps specifically after your irrigation system starts running for the season, check it directly rather than assuming the leak is indoors.

Conversely, a leak that appears in winter with no irrigation running at all more reliably points indoors, toward a fixture, a slab line, or in rare cases a frozen and cracked section that hasn't fully failed yet. The season a jump appears in is itself a useful clue worth factoring into where you look first.

Where your responsibility ends and the utility's begins

Calhoun Utilities is generally responsible for the water main and the service line up to and including the meter itself; everything from the meter into your house is the homeowner's responsibility, which is exactly the boundary the meter test is designed to check. If the meter test shows no movement but you're seeing wet ground near the street or the meter box, that's worth reporting directly to Calhoun Utilities rather than treating as a plumbing issue.

This distinction matters because a leak on the utility side of the meter doesn't show up on your bill or your meter reading at all, since you're not billed for water that never reached your meter. A wet spot in the yard between the street and your meter, with your own meter test showing no movement, points toward the utility's line, not yours.

A word on outdoor spigots specifically

Frost-free outdoor spigots have a long internal stem that can develop a slow leak inside the wall, invisible from outside, if the spigot was ever left connected to a hose over winter or the stem washer has simply worn out over years of use. Disconnecting hoses before winter and checking each outdoor spigot briefly each spring, before irrigation season ramps up, catches this specific leak type early rather than discovering it through a rising bill months later.
