FAQ

What affects water softener cost?

Hardness level, system capacity and type, plumbing access and whether new drain or bypass lines are needed.

Do I need a water test first?

Yes — hardness and iron levels determine the right system and size.

Salt-based or salt-free?

Salt-based removes hardness minerals; salt-free conditioners reduce scale but do not remove minerals.
