How do I know if I have a hidden water leak?
Turn off every faucet and water-using appliance, then check your water meter. If the meter’s leak indicator (a small triangle or dial) keeps moving, water is escaping somewhere. Other signs include a sudden jump in your bill, damp spots, mildew smells and the sound of running water.

- Meter moving with all water off

How professional leak detection works
Plumbers combine several non-invasive tools to narrow a leak to a small area before cutting anything — saving drywall, tile and money.
Acoustic listening
Ground microphones pick up the sound of pressurized water escaping, even under concrete.
Thermal imaging
Infrared cameras reveal temperature differences from hot-water leaks and wet materials.
Pressure & isolation tests
Isolating hot, cold and irrigation lines shows which system is leaking.

Leak Detection FAQs
How much does leak detection cost in Maricopa?
Most leak detection visits in Maricopa cost about $150–$500. Larger homes or multiple suspected leaks may cost more.
Can a plumber find a leak without breaking walls?
Usually, yes. Acoustic, thermal and pressure tools let plumbers pinpoint most leaks to a small area, so only a minimal opening is needed for the repair.
Why is my water bill so high?
A leaking toilet flapper, an irrigation leak or a hidden slab leak are the most common causes. Do the meter test with all water off to confirm a leak.
Does homeowners insurance pay for leak detection?
Some policies cover the cost of finding and accessing a leak when it causes sudden water damage. Coverage varies, so check your policy and keep all invoices.
