Can you have a slab leak and not know it?
Yes. Cold-water leaks give no warm spot, and small ones barely move the meter. A pressure-gauge test catches leaks too small to see any other way.
How long can a slab leak go undetected?
It can run for months or longer if the water soaks into the soil rather than surfacing. Often the only clue is a water bill that keeps climbing.
How do you find a cold water leak under a slab?
Because a cold leak does not warm the tile, a thermal camera will not see it. Each line is isolated and tested, then the run is followed with acoustic equipment.
