Leak Detection Guide
Pressurized water escaping through even a small opening creates a distinct sound signature, one that travels through pipes and surrounding material. Acoustic equipment amplifies and isolates that specific frequency, letting a technician trace it to a precise point rather than guessing at a general area.
Thermal cameras detect temperature differences, which is useful because a leaking water line — hot or cold — changes the surface temperature of the material around it just slightly. That temperature variance shows up clearly on a thermal image even when nothing is visible to the naked eye.
A waterproof camera is fed directly into sewer or drain lines, sending back a live video feed of the pipe's interior condition — showing cracks, root intrusion, or blockages exactly as they appear, rather than inferring the problem from outside symptoms.
Pressure testing involves sealing a line and monitoring whether it holds pressure over time. A drop in pressure confirms a leak exists somewhere in that section, which then narrows the search for the more precise acoustic or camera-based methods.
Without precise detection, finding a leak the old-fashioned way often means opening up much more wall, flooring, or ground than the leak actually requires, just to visually locate it. Precision detection means the eventual repair only touches the exact point that needs it.
Even with precise detection, the confirmed leak point still generally needs to be accessed for the actual repair — but that's a small, targeted opening at one specific spot, not exploratory digging or demolition across a wide area.
