Not cooling, ice maker calcium, seasonal scale — Same-day, fixed quote.
Herriman refrigerator repair confronts the single most dramatic water-hardness swing anywhere on the Wasatch Front. During off-peak months, the city draws from Jordan Valley Water Conservancy surface water at a moderate 10-15 grains per gallon. During peak summer demand, Herriman activates groundwater wells — some testing 50-60 grains per gallon, roughly 850-1,000+ PPM. A refrigerator installed in February faces dramatically different conditions by August.
GPG off-peak — Jordan Valley Water Conservancy surface supply
GPG peak summer — well water, among the hardest documented anywhere
Most hard-water markets have one number that stays roughly consistent year-round. Herriman doesn't work that way. As summer demand rises, the city activates wells — Hamilton Well, Well #1, Wells #3 and #4, Stillman Well — that can run 35-60 GPG, compared to 10-15 GPG from surface supply the rest of the year. This means an ice maker fill valve that shows zero symptoms all winter can begin rapid calcium accumulation the moment peak-season wells come online in June or July. We size inline filtration for Herriman's worst-case summer hardness, not the gentler winter baseline.
