Recommended for this suburb

Dalkey's water is hard at 138 mg/L — you're cleaning scale off things that shouldn't need cleaning.

At this level, you'll see white rings inside the kettle, cloudy spots on glassware, and shampoo that never lathers properly. Over 5–10 years, scale slowly kills heating elements in your hot water system and dishwasher — the damage is invisible until they fail 2–3 years early. Boiling doesn't help; it concentrates the minerals.
