Te problem is on GPS side.
Viking explained the GPS he use only take POI with a name field without
additional attributes.
Then it's harder to distinguish presurized hydrants vs suction points but
not impossible : concatenate water_source with ref or arbitrary label
(hydrants don't usually have names) and you're done.

+1 on idea

Capacity is used several hunder thousand times but flow_capacity never
(fire_hydrant:flow_capacity about 7k).
Since capacity definition is "The tag describes the capacity a facility is
suitable for", it can fit for pipelines, hydrant, canals, drains... in m3/s
or m3/h, can't you ?
