What Affects Water Softener Costs?

1. System type — Salt-based ion exchange systems ($800–2,500) are most effective for San Diego's very hard water. Salt-free conditioners ($500–1,500) don't remove minerals but can reduce scale.
2. Grain capacity — A 32,000-grain unit handles a family of 4; 48,000–64,000 grains for larger households. Higher capacity costs more upfront.
3. Installation requirements — Installing a dedicated outlet, drain line, and bypass valve adds $200–500. Homes with existing plumbing prep cost less.
