Szentjakabfa is reported at 549.7 mg/L as CaCO₃ in the 2024 NNGYK data, which is very hard and the highest in this batch. The dataset does not name the source, so we cannot explain the cause for this village. Heavy limescale in heaters and appliances is likely, and a softener or regular descaling is worth considering.
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

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).
