Main Water Line Leak Detection in Spokane
The service line between your meter and house can leak underground for months, especially in older galvanized or copper lines. Wet spots in the yard, oddly green grass or a sinking area near the front of the house are clues. We use line tracers to map the pipe and ground microphones to hear the leak. That keeps excavation to a small, focused hole.

Sewer Line Leak Detection in Spokane, WA
Sewer line leaks can cause unpleasant odors, slow drains and potential health hazards. Our team uses camera inspections to visually identify breaks, cracks or blockages within your sewer lines. This method allows for precise location of the leak without guesswork, leading to more efficient and targeted repairs. We address sewer leaks in all types of piping materials common in Spokane homes, from PVC to cast iron.
Irrigation and Yard Leak Detection in Spokane, WA
Drip and sprinkler systems are a common source of hidden water loss in most yards. A cracked lateral or a stuck valve can waste thousands of gallons before anyone notices. We test the irrigation system separately from the house and trace leaks along buried lines. Many water providers recommend checking irrigation first when bills spike in summer.
Commercial Leak Detection in Spokane
FHN Plumbing offers complete leak detection services for commercial properties throughout Spokane. Businesses cannot afford the downtime or damage caused by undetected leaks. We work efficiently to locate leaks in complex commercial plumbing systems, including large water mains, fire suppression lines and HVAC systems. Our goal is to minimize disruption to your operations while protecting the integrity of your building's plumbing.
Fixture and Appliance Leak Detection in Spokane, WA
Running toilets, worn faucet cartridges and leaking water heater connections waste more water than most people realize. A silent toilet leak can lose hundreds of gallons a day. We check flappers, fill valves, supply lines, softeners and water heater fittings. These repairs are typically quick and inexpensive.
Gas Leak Detection Services in Spokane
Gas leaks are extremely dangerous and require immediate professional attention. Our team is equipped with highly sensitive gas leak detectors to promptly identify the location and severity of any gas escape. We put safety first and will guide you through the necessary steps, including shutting off the gas supply and coordinating with your utility company, to ensure your home is secure.
Pool and Spa Leak Detection in Spokane
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak safeguards the pool shell and the soil around it.

Underground Water Line Leak Detection in Spokane, WA
Leaks in underground water lines, often leading from the meter to your home, can result in serious water loss and property damage. We employ ground microphones and tracer gas detection to locate these buried leaks precisely. Factors like tree roots, ground shifting and corrosion in older galvanized pipes can contribute to these issues, making professional detection important.

Frequently Asked Questions About Leak Detection in Spokane
The cost of leak detection in Spokane, WA can range from $250 to $800, depending on the complexity and location of the leak. Factors like slab leaks or hard-to-reach pipe leaks may be at the higher end. We provide a written estimate after our initial assessment.
Many homeowner's insurance policies cover the cost of repairing sudden and accidental leaks, and sometimes the cost of leak detection itself, especially if it leads to a covered repair. It's best to check your specific policy or contact your insurance provider for details.
Small repairs typically do not, but reroutes, repipes and main line replacements often do. Requirements vary by city and county. We handle any permits needed.
Municipal water west of the mountains in Washington is generally soft, while supplies on the drier east side tend to run harder. Hard or aggressive water can cause pinhole corrosion in copper pipes over time. Slab foundations on shifting soils also put stress on pipes underneath the house, and high water pressure in some areas adds more stress.
If you suspect a gas leak, immediately evacuate everyone from the property, do not use any electrical devices, and call your gas utility company and FHN Plumbing from a safe location. Gas leaks are very dangerous and require immediate professional attention.
We use acoustic ground microphones, thermal imaging cameras from brands like FLIR, line tracers, moisture meters and pressure test gauges. Each tool helps confirm a different type of leak. Using several together gives reliable results.
Older galvanized steel pipes are prone to corrosion, and some older polybutylene pipes are known for early failure. However, even modern materials like copper or PEX can leak due to improper installation, high water pressure or foundation movement.
Older homes may have galvanized steel or polybutylene pipes, both known for higher leak rates due to corrosion or material breakdown. Copper pipes can develop pinhole leaks over time, while PVC and PEX are generally more reliable but can still leak at fittings or due to installation errors.
