Frequently Asked Questions
How do I know if I need a water softener?
Test your water hardness. Above 7 grains per gallon (GPG) is considered hard and benefits from softening. Signs include white scale on fixtures, soap that doesn't lather well, and dry skin/hair.
Do water softeners add sodium to drinking water?
Yes, but a very small amount — about 12-25 mg per 8 oz glass for moderately hard water. This is less than a slice of bread. For sodium-free options, consider a reverse osmosis filter at the kitchen tap.
Why does water softener installation cost different in San Jose than other cities?
San Jose's costs reflect local labor rates driven by the tech-manufacturing economy, mediterranean climate conditions that affect materials and scheduling, and strict permitting requirements. The expensive labor market also influences competitive pricing.
