If you’re budgeting a water softener installation in San Jose, most projects run $1,041-$4,163, 30% above the $1,500 national average. What moves that number most is usually one thing: System Capacity and Grain Rating. On its own it can swing the cost by $300 - $2,500 in equipment, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Test your water hardness before buying a system - either with a $10 test kit from a hardware store or a free test from your water utility. This determines the size you actually need.
