Water softener and filter costs in San Jose
A salt-based water softener in San Jose typically costs $1,200 to $3,800 installed, and a whole-house filter $850 to $3,500. These are published national ranges with California labor noted, not local quotes.
Why San Jose jobs vary
San Jose has three water utilities and several supplies, so the right system changes by address. See which water you have.
- Hard well or creek water: the job is usually a softener, often with reverse osmosis for drinking water.
- Chloraminated imported water: the job usually includes catalytic carbon, which costs more than standard carbon.
- Existing softener loop: a home without one needs new plumbing, about $350 to $650 on the West Coast.
