Ich habe eine (Namhafte) Enthärtungsanlage in einem anderen Stadtteil montiert und in Betrieb genommen. (Ich bin SHK Fachmann). Mit dem Wassertester der Enthärtungsanlage habe ich dann auch mal die Wasserhärte in Iserbrook (Hamburg) mehrfach getestet, an unterschiedlichen Zeiten und Tagen. Stand August 2021 liegt die Härte zwischen 11 und 12 °dH.

The water hardness directory is a community that allows each user to enter values for each city in the directory. Nothing but a user account is needed. The system controls itself practically, since each one can convey a value and from all values the average degree of hardness is determined. Nevertheless, all information is given without guarantee and should be checked in case of doubt.
