NNGYK's 2024 drinking-water report lists tap water in Szin at 421.2 mg/L as CaCO₃, which falls in the very hard band. We have not confirmed which supply source serves the village, so this note describes the figure rather than the geology. At this level, expect limescale on kettles, shower screens and heating elements.
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).
Estimates for planning, not a quote. Check your appliance manual for exact settings.
