Recommended for this suburb

Ngarkat's tap water is 'very hard' at 228 mg/L — and scale is building up in your home right now.

Every time you boil a kettle or run the hot tap, calcium is baking onto heating elements. Hot water systems, dishwashers, coffee machines, shower screens and glassware all take the same damage. "Descaler tablets" treat the symptom; they don't stop the mineral from entering your home in the first place.

A reverse-osmosis system blocks 95%+ of dissolved minerals before the water reaches your tap. No plumber needed — it fits under the kitchen sink in a Saturday. The drinking water, ice, tea and coffee all taste clean for the first time. Reducing scale at the tap helps protect the appliances you use every day.
