There's water coming up under my floorboards. Is it a slab leak or something else?
It can also be a leaking dishwasher line, a failed water heater, or storm water that came in low. A slab leak usually shows up with one of the other signs — a moving meter with everything off, a warm patch on the floor, or the sound of running water in a quiet house. A plumber confirms it; the drying starts either way.
