fire_hydrant:main_diameter is the same as fire_hydrant:diameter - at
least in the current tagging usage and 'mappers meaning'.
fire_hydrant:diameter is used for the _main_ _pipeline_ diameter, where
the hydrant is fed from - as this is indicating the possible value of
the water supply. (In theory the pressure is normalized ... in practice,
Sure, this is a bit misleading ... it was developed from a german point
of view regarding the signs and a short-as-possible key ...
The hydrant pipe inner diameter is not tagged yet - afaik.
In Germany the interfaces are standardized anyway - and the
(underground) standpipe diameter may possibly vary (50, 80, 100), as it
is a movable part from the fire brigade.
