Before reading a meter, check whether the situation is safe
Use only a meter display that is safely accessible to you. Some meters sit in buried pits or locked utility housings; do not enter pits, open sealed equipment, or interfere with utility-owned fittings. If you cannot safely read the meter, ask the water utility for its instructions or a usage report.
The two-hour no-water-use comparison
Choose a period when nobody will use taps, toilets, appliances, irrigation or other water-using systems. Record the meter reading, the time, and if possible a clear photo of the display. Wait approximately two hours with no intentional water use and compare the display. EPA WaterSense advises that a change can indicate a leak. Different meters have different units and display formats; follow your utility's meter-reading instructions.
What a changing reading tells you—and does not tell you
A changed reading during a truly inactive period raises a leakage concern, but it does not identify which fixture, pipe or valve is involved. First make sure there was no toilet refill, washing cycle, water-softener regeneration, irrigation, humidifier or other intended draw. If any water use occurred, repeat the controlled observation before assuming a hidden pipe failure.
Separate obvious fixtures from a possible hidden loss
With normal access and no safety concern, look for dripping faucets, moisture under fixtures, a running toilet, dampness around supply hoses and changes in outdoor irrigation. A toilet dye test can reveal an internal tank leak even when the floor is dry. Do not start excavation or open finished walls solely because a meter reading changed.
When to contact a utility versus a plumber
Ask the utility about meter accuracy, display interpretation, unexpected billed usage, or responsibility for the service line before assuming every component is yours to repair. Ask a qualified plumber about a persistent unexplained reading, wet structure, damaged fittings, or a repeated leak indication. Responsibility and permit requirements can vary by local authority and the location of the fault.
Provide a useful evidence pack
Keep the two readings, timestamps, photos, relevant billing comparison and a list of fixtures that were deliberately kept off. Record any water-softener cycles, outside irrigation, recent renovations and nearby moisture. This lets an independent professional evaluate the suspected supply-side problem rather than treating a single high bill as proof.
Quote questions without invented prices
Ask whether the proposed service is inspection, leak localization, repair or restoration. Understand diagnostic fees, whether detection work is non-invasive, what evidence supports invasive access, who handles municipal permission, and whether repairs affect landscaping or interior finishes. Request written scope and warranty terms; there is no credible blanket repair cost for all Ohio properties.

Common homeowner questions
Why should I wait two hours for a water-meter check?
EPA WaterSense uses a two-hour period without water use to compare readings. This is a homeowner screening method rather than a pressure test or definitive professional diagnosis.
Can I open the street meter box to inspect the supply line?
Do not open locked, sealed, unsafe or utility-controlled equipment. Ask your water utility for safe access and reading guidance.
