Is Brisbane's Water Hard? What It Does to Your Plumbing
Brisbane's water is officially 'moderately hard'. Not Adelaide-level, but enough to shorten the life of every appliance in your home.
What Hardness Actually Does
Dissolved calcium and magnesium precipitate out when heated, coating heating elements and pipe walls. A 3mm scale layer inside a hot water system cuts efficiency by ~25%.
Visible Signs
Scale rings in kettles, white spots on tapware, reduced flow at showerheads, and gradually rising energy bills.
Filtration Options
Whole-of-house softeners: $2,400–$3,800 installed. Point-of-use filters at kitchen: $450–$650. Showerhead descaling filters: $80–$120 each.
Is It Worth Softening?
For most Brisbane homes: no, hardness is manageable. For homes with young kids on scale-sensitive appliances, or with existing scale damage: yes.
Frequently Asked Questions
Does softened water taste different?
Slightly saltier because the softening exchanges calcium for sodium ions. Most people don't notice.
