The method

Very much so. Leaks on the cold side stay invisible because they add no warmth, and the water can soak away into the ground rather than show up indoors.
Without heat to follow, the search relies on isolation and sound. Each cold branch is tested on its own, then listening equipment homes in on the failure.
It happens. Hot lines, in-floor heat or sunlight can warm a spot. A gauge test settles it quickly, so you are not paying for a repair you do not need.
