Your water bill jumps, and nothing in the house has changed. No new guests, no new lawn watering, no long showers. That jump is one of the most common plumbing calls in Brentwood, and it usually means water is going somewhere you cannot see. A pinhole leak in a copper line, a toilet that runs at night, or a slab leak under the floor can waste hundreds of gallons a month while the house looks dry. The good news is that the first check is free and takes five minutes: the water meter. Turn off every tap and water-using appliance, then watch the meter leak indicator. If it moves, water is leaving the house. Note the reading, wait an hour with everything off, and read it again. A higher second reading confirms the leak. From there, the pattern tells the story. A bill that climbs slowly, month after month, points to a small, steady leak. A bill that jumps suddenly points to a bigger failure, like a slab leak or a burst line. A warm spot on the floor or the sound of running water with taps off narrows it further. Brentwood homes have two local reasons for these leaks. The water is moderately hard, so scale and corrosion wear on fittings and older copper lines. Many homes built in the 1970s and 1980s still run copper supply lines that develop pinhole leaks, often with green staining at the joint. Expansive clay soil adds movement that stresses joints under slabs. If your meter confirms a leak, shut the water off at the meter if you need to, take photos of the meter readings, and call us. We confirm the leak with a pressure test, narrow it with acoustic and thermal tools, and repair only the section that failed. Keep the bill and the meter readings: your insurer may ask for them if there is water damage.

Frequently Asked Questions
What should I do first if my water bill jumps?
Check the meter leak indicator with all taps off. If it moves, you have a leak. Note the reading, wait an hour, and read it again, then call (615) 576-1152.
Can a running toilet really raise my bill that much?
Yes. A toilet with a worn flapper can waste hundreds of gallons a day, and it often runs quietly at night when no one hears it.
Is a high bill always a leak?
Not always. A new lawn watering schedule, a houseguest, or a faulty meter can also raise a bill. A meter test with everything off separates a leak from a use change.
Will my water provider help?
Brentwood City Water Services can confirm your usage history. That record helps us see when the jump started, which narrows the search.
