Water Leak Under a Driveway in Nampa: A Wet Strip, the Meter Test and Why Digging Starts at a Marked Spot

A water leak under a driveway in Nampa shows as a wet strip or a green patch, and the leak itself is never visible — the service line is buried under concrete, and water follows the path of least resistance, so the wet patch may appear at the edge of the driveway, at a joint, or in the yard beside it, rather than directly above the failed pipe. The test that separates a supply leak from irrigation is the meter test with irrigation off: turn the irrigation system off completely, turn off taps, showers, washing machine, dishwasher and ice makers, note the meter reading and whether the leak indicator is moving, wait without using water, then recheck. If the meter moves, water is leaving the supply line, and a wet strip along the meter-to-house route points to the buried line. If the meter is still and the strip dries between watering days, irrigation or drainage is the more likely cause. A sinking slab is a later sign: it means soil is being washed away under the concrete, and it should be checked promptly rather than watched. On a detection visit, listening along the meter-to-house route and pressure checks narrow the line to a marked spot, and digging starts at that marked spot, not at the wet patch.
