Leaks beneath a concrete slab can be difficult to locate without the right equipment. Because the piping is not visible, identifying the exact source of the problem requires specialized tools and a careful diagnostic process.
For this project in Coeur d’Alene, we performed leak detection at a church facility after signs of a hidden plumbing issue were identified. Situations like this often involve underground piping where traditional inspection methods are not effective.
Using professional leak detection equipment, we were able to narrow down the location of the problem without unnecessary excavation.
Locating a Leak Beneath the Slab
The source of the issue was found in a hot water recirculating line beneath the concrete slab. Recirculation lines are designed to keep hot water readily available, but when a leak develops in this type of system, it can be difficult to detect without specialized tools.
Electronic detection equipment was used to identify the exact location of the leak by analyzing sound and pressure changes within the system.

Why Accurate Leak Detection Matters
Pinpointing the location of a leak before opening the slab helps minimize disruption and reduces the amount of demolition required to access the damaged pipe.
Without accurate detection, multiple areas may need to be opened in an attempt to locate the problem, increasing both time and cost.
Projects like this are part of the plumbing work we perform throughout the area, including specialized diagnostics in Coeur d’Alene. You can learn more about our services on our Coeur d’Alene plumbing page.
Identifying leaks early and locating them accurately is key to preventing further damage and completing repairs efficiently.
