Can I Use a Water Meter Test to Find a Leak Myself?

Yes, a water meter test can help you confirm a hidden plumbing leak at home. The most common reason the meter moves when no water is in use is a running toilet, with service-line leaks another frequent cause. If your test points to a problem, Lanz uses electronic leak detection, sewer cameras, and other non-invasive tools to pinpoint the source before recommending repairs. Homeowners we serve across Champaign benefit from minimally invasive options that reduce disruption.

Try this simple meter test:

• Shut off all fixtures, irrigation, and appliances; check the meter’s leak indicator or dial.
• If it moves, isolate fixtures; start with toilets by closing their shutoff valves and retesting.
• If it seems still, record the reading, wait 30 minutes, then recheck; any change confirms a leak.
• Close the home’s main shutoff; if the meter still moves, the leak is likely between the meter and the house.

If the meter indicates a leak, avoid digging or guessing and schedule a professional diagnosis to prevent extra damage.
