[Tagging] fire hydrants

[Viking]

Hi.

I have a question about this wiki definition:

 

 <https://wiki.openstreetmap.org/wiki/Key:fire_hydrant:diameter>
fire_hydrant:diameter=# (optional, in mm, inches or letters. This is the
diameter of the water main feeding the hydrant. )

 

Is this the diameter of the underground pipe or the diameter of the threaded
outlet?

In case of the underground pipe diameter, it is almost always unkwown for a
normal OSM mapper.

In case of the threaded outlet, we have often multiple outlets with
different diameters as in this case [1]: which diameter should we tag? The
bigger one? Or all diameters separated by semicolons?

And finally, how we tag the number of multiple outlets? fire_hydrant:count=#
should be used to tag the number of hydrants, not of outlets, right?

 

Perhaps to tag an hydrant like this [1], supposing it has two 45 mm outlets
and one 100 mm outlet, it would be correct to use:

emergency=fire_hydrant

fire_hydrant:type=pillar

fire_hydrant:diameter=45;45;100
