Pressure Testing & Isolation in Spokane Valley
When a leak is suspected, we can perform pressure tests on individual water lines. By isolating sections of your plumbing system and monitoring pressure gauges, we can confirm the presence of a leak and often determine which particular line is compromised. This systematic approach is crucial for homes with complex plumbing layouts, giving you an accurate diagnosis before any excavation in Spokane Valley, WA.

Repiping After Multiple Slab Leaks in Spokane Valley, WA
If your home has had two or more slab leaks, the remaining pipe is likely corroded too. Repiping replaces all supply lines with new PEX or copper run through the walls and attic. It is a bigger project, but it ends the cycle of repeat slab leaks. We can usually complete a full repipe in two to four days.

Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are equipped to identify both types of leaks, which present different challenges.

Electronic Leak Detection in Spokane Valley
For elusive leaks, our electronic leak detection equipment sends a signal through your pipes and measures changes that indicate a breach. This technology allows us to locate leaks in various pipe materials, including copper, PEX and PVC, commonly found in Spokane Valley homes.

Video Pipe Inspection for Sewer Leaks in Spokane Valley, WA
Sewer line issues under a slab can also mimic slab leak symptoms. We use high-resolution video cameras to inspect the interior of your drain lines, identifying cracks, blockages or separations.

Frequently Asked Questions About Slab Leak Detection in Spokane Valley
The cost of slab leak detection in Spokane Valley, WA typically ranges from $250 to $700, depending on the complexity of the leak and the time required for detection. This cost covers the specialized equipment and expertise needed to accurately locate the leak, which is crucial before any repair work can begin.
Yes. Water leaking under the slab can cause expansive soil to swell or wash away supporting soil. Over time this can lead to cracks and sinking. Fixing leaks quickly protects the foundation.
Many homeowner insurance policies cover the cost of water damage from a sudden or accidental slab leak, and sometimes the cost of accessing the leak for repair. However, coverage varies a lot, so it's essential to check your specific policy with your insurance provider.
For significant slab leak repairs, especially those involving excavation or extensive re-piping, a plumbing permit from the local building department is often required. FHN Plumbing handles all necessary permitting processes so your repair is compliant with local codes and regulations, protecting your investment.
While you can look for the signs, precisely detecting a slab leak requires specialized equipment and expertise that most homeowners don't have. DIY attempts often lead to more damage or misdiagnosis, making professional detection a more cost-effective and reliable solution in the long run.
Common pipe materials prone to slab leaks include older copper pipes susceptible to corrosion from hard water or soil acidity, and sometimes PEX or CPVC if they were improperly installed or exposed to extreme temperatures. Galvanized steel pipes, though less common under slabs today, can also corrode and leak.
FHN Plumbing relies on industry-leading brands for our slab leak detection equipment, including but not limited to LeakTronics, FLIR thermal cameras and specialized acoustic sensors. These tools are chosen for their accuracy and dependability in various leak detection scenarios, delivering the best results for your home.
Direct repair works well for a single leak on otherwise healthy pipe in an accessible spot. Rerouting is often better under tile or hardwood and avoids future leaks on that line. We help you compare both.
