An ice maker line leaks under the kitchen and into the basement
This is a pattern we see in newer Lehi homes near Thanksgiving Point and the Silicon Slopes corridor: the small plastic or braided line feeding a refrigerator's ice maker cracks behind the fridge, and water runs under the kitchen floor and down into the finished basement below.
These leaks are often found late. The water runs behind and under the refrigerator where no one looks, soaks under the flooring, and only shows up as a stain on the basement ceiling or a damp spot on the carpet downstairs. On the call we have you shut the valve behind the fridge or the main, and we ask whether anything below is near ceiling lights or recessed cans.
We document both floors before touching anything: photos of the failed line, the kitchen, the basement ceiling, and each wall, plus moisture readings marked on a floor plan. Newer Lehi kitchens usually have luxury vinyl plank or laminate over an underlayment, and that floor looks fine from above while holding water underneath. Readings are what tell us how far it spread — often under the island and into the next room.
The kitchen decisions come down to materials. Cabinet toe-kicks are pulled so air can reach under the boxes; particleboard cabinet bases that swelled are noted for replacement, while sound ones are dried. Luxury vinyl plank is waterproof on top but traps water beneath it, so a few rows are lifted to dry the subfloor. Laminate with a fiberboard core and foam underlayment that soaked up water can't be dried back flat and is replaced. The OSB subfloor is usually dried in place with airflow and dehumidification and verified with readings.
Downstairs, the basement ceiling drywall and any insulation above it get the same careful look. Clean water caught within a day or two often lets us dry the ceiling in place with a few access holes; drywall that sagged, or insulation that soaked through, comes out. Following the IICRC S500 reasoning, those calls depend on the water category (this started clean), the class of loss (how much and how deep), how long it sat, and whether each material can release moisture where it is. Every removal is photographed with its reason.
When both levels reach the dry standard, we write a rebuild scope that covers the kitchen floor, any cabinet bases or toe-kicks, the basement ceiling patch and paint, and a new braided ice maker line so the failure doesn't repeat.
