Frequently Asked Questions About Leak Detection

We handle both precision detection and complete plumbing repairs! Unlike diagnostic-only firms that simply locate a leak and leave you searching for another contractor, Medford Leak Detectives is a fully plumbing services contractor. Once our precision acoustic and thermal equipment isolates the likely failure area, our technicians can perform immediate spot repairs, sub-slab copper soldering, acoustic overhead PEX line rerouting, main water service line replacements, or pressure regulator installations. One phone call takes care of the diagnosis and the permanent fix from start to finish.

Turn off every faucet, valve, appliance, and outdoor irrigation line in your home. Locate your Medford Water Commission meter box near the street curb. Open the lid and check the leak indicator—either a small red triangle, a silver spinner, or a digital readout. If this indicator is moving while all indoor and outdoor water valves are firmly shut, water is escaping through a pressurized leak in your plumbing system or main service line.

Under Medford Water Commission guidelines, the municipal utility owns and maintains the water main and the water meter. The property owner is responsible for the private service line running from the meter outlet into the residence or commercial building. If a leak occurs between the meter and your home, the property owner is responsible for detection and repair.

Common symptoms include unexplained warm areas on hardwood, tile, or carpet; the faint hissing or rushing sound of running water behind baseboards; sudden drops in hot water pressure; cracks appearing in foundation walls or flooring; damp, mildewed drywall near the floor; and sharp spikes in your monthly water utility bill.

We utilize high-sensitivity acoustic ground sensors and correlators that amplify the high-frequency vibration of water escaping under pressure. We combine this with thermal infrared cameras that map thermal gradients (hot or cold water pooling under floors) and non-toxic helium tracer gas to help locate leaks within inches without opening walls or jackhammering concrete.

Most standard homeowner insurance policies cover the cost of accessing the leak and repairing resultant water damage if the leak is sudden and accidental. While the pipe repair itself is often a maintenance cost, our specialized acoustic diagnostic reports provide the documentation required by insurance adjusters for claim approval.

Winter freeze-thaw cycles in the Rogue Valley cause water trapped in uninsulated crawl spaces, exterior hose bibs, or unheated attics to freeze. As water freezes into ice, it expands, causing internal pressure to spike up to several thousand PSI until the copper, PEX, or galvanized pipe wall ruptures.

Our Medford-based mobile service fleet allows us to reach any neighborhood in Medford — including East Medford, West Medford, Downtown, and surrounding areas — promptly with priority emergency response.

Yes. We perform specialized pressure decay tests and underground line tracing for residential and commercial irrigation systems, locating cracked PVC pipes, failing zone valves, and root-damaged lines beneath lawns and hardscaping.

Yes. Medford Leak Detectives provides full-service plumbing repairs across Medford and Jackson County.

It is a useful warning sign, but it does not identify the cause by itself. Make sure toilets have finished refilling and that irrigation, ice makers, water softeners, and other automatic water users are not running. A leaking toilet flapper or an outdoor line can also register use. If the meter continues to show flow with water use stopped, note the reading and arrange a plumbing or leak-detection assessment. For a suspected private service-line issue, confirm which side of the meter is involved.

Describe what first alerted you—such as a higher bill, damp flooring, a warm patch, a ceiling stain, or a meter that continues to move. Tell them which fixtures and water-using equipment you have checked, whether the main shutoff changes the meter reading, and whether the suspected area is under a slab, in a wall, or outside. Share any prior pressure tests or repairs. These details help the technician choose a suitable test; no single tool is effective for every pipe material or leak condition.
