Čichtice in Jihočeský kraj is served by ČEVAK a.s. The reported hardness is 115.1 mg/L as CaCO₃, in the moderate category, and the value dates from 2025, so it may be a little older than most. The source gives no information on the origin of the water. Limescale appears slowly at this level, mainly in kettles and on taps.
Czech suppliers report "Vápník a hořčík" in mmol/L; the recommended range is 2–3.5 mmol/L.

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).
