Please keep in mind, there already a rather big list of possible tags:
(only in German) and what the OpenFireMap displays (the diameter):

See http://de.wikipedia.org/wiki/Hinweisschilder_zu_Stra%C3%9Feneinbauten
(sorry, also German).

Most important value (and shown on OpenFireMap in z17) is the nominal diameter,
which classifies the hydrant. It is the inner diameter of the pipeline in
millimeter and is typically 50, 80, 100, 150, 200, 250, 300, 400.
