Scale still appears where groundwater is in the mix, but mechanical and electronic faults take a larger share of our calls here. We confirm the supply before assuming scale.
Sunnyvale's blended Hetch Hetchy supply runs softer than San Jose Water's, which changes what fails and why.

Usually mineral content and restricted water flow. Hard water leaves cloudy cubes and slowly chokes the fill valve, cutting cube size. We diagnose the flow restriction and fix the cause, not just the symptom.
