Recommended for this suburb

Wirrina Cove's tap water is 'very hard' at 258 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.
