In the northern hills, supply is drawn from karst springs and wells in limestone and volcanic rock; the exact source for Detk is not confirmed here. Limestone-fed karst water is the hardest in the area, while water from volcanic rock is softer; the 2024 national report lists Detk at 414.1 mg/L CaCO₃ (very hard). Limescale forms fast on heating elements, taps and glass, which makes a softener or descale routine worthwhile.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
