The old way of finding a slab leak was jackhammering exploratory holes and hoping. The modern way is genuinely impressive: sensitive microphones hear water escaping through a pinhole, infrared cameras see heat blooming through tile, and tracer gas sniffed at the surface traces the exact path of the leak. This section explains each method, when pros use which, and what a proper diagnosis should include.
