This figure is over 3 years old; hardness may have changed.
Eichenau is supplied through the network of the AmperVerband (Zweckverband Wasserversorgung der Ampergruppe), and the figure of 12.8 °dH comes from a shared network sample, not from Eichenau alone. The utility's extract is dated 27.09.2022, so it is more than four years old and the page marks it as stale. The same network also serves Gröbenzell, and the analysis classes the water as medium hard. Check the AmperVerband's current analysis before relying on the number.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.

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).
