Pipe under the concrete
Valley homes on a slab often run copper supply pipe under or through the concrete, where wear and movement go unseen.
Clay that moves
Clay soils in the San Ramon Valley swell in the wet winter and shrink in the dry summer, which puts stress on the slab and the pipe beneath it.
The water spreads first
A slab leak can run for weeks before it shows, soaking flooring, baseboards and the bottom of walls well away from the pipe.

Slab Leak Warning Check questions
What is the meter test?
Turn off every faucet and water-using appliance, then watch the water meter for 15 minutes. If the dial or leak indicator moves, water is going somewhere.
Why does a slab leak make a warm spot?
A leak on the hot water side heats the concrete above it, so a warm patch on tile or wood is a common sign.
Who finds the leak?
A plumber with leak detection equipment locates it, then repairs the pipe or reroutes it through the walls or attic.
What should happen if the floor is wet?
Shut the main valve, keep wet flooring from being covered, and photograph the floor before anything is lifted.
Does a slab leak always show water?
No. Many slab leaks drain into the soil and show only as a higher bill, a warm floor or the sound of running water.
