Is amenity suited? man_made=fire hydrant would be better to my opinion, because an hydrant is not intended to be used by everybody. And it it not used in a convenient/pleasant way. ---user:HB9DTX

Agree, but it comes in same category as amenity=prison and amenity=architect_office. I do not find a prison pleasant (prefer not to have one close to my house or near my hotel), and never used an architect_office in a pleasant way... --Skippern 01:00, 6 January 2010 (UTC)

I think the standard tag should be emergency=fire_hydrant. My reasoning is that an amenity is a general use or large population use location, where a hydrant is only legally used by emergency services. A prison still fits into amenity for the same reason, as the general population (criminal) is housed in such a location, but the facility isn't exclusively used by inmates - for example visitors. A fire hydrant is only used by emergency services and occasionally by some member of the government aka water authority. I also think the 'man_made' feature is silly, there is no need to define that a fireplug is man made because the structure is not created naturally. Man_made makes sense for things like ponds which also can be natural to differentiate the two types. Rjhawkin 03:14, 31 July 2011 (BST)

With your argument about prisons, one could also include apartment buildings, a lot of people are housed in them. --Skippern 03:48, 6 September 2011 (BST)
That is a spurious argument as people living in an apartment house are doing so under a limited amount of choice while a prison is less about living location.Rjhawkin 18:36, 20 January 2013 (UTC)

Wrench used to open

In the place where I live, there are some hydrants that are secured, that is you have to open it using a square or pentagonal wrench. I think that this distinction could be useful (which wrench has to be used, if any...) --SteveVG 17:22, 20 July 2012 (BST)

This is not needed in my opinion. The people who have legitimate needs to access a hydrant know what types of wrenches are needed. Knowing where a hydrant is on the other hand is important in the sense that it allows generation of fire protection area maps and can affect the response time during a fire or related emergency. It could even affect how long it would take to fill a private pool since they are used for that purpose as well. The problem with unauthorized opening of fire plugs is that because the volume of water is so great it can decrease the water pressure available in that area for other municipal users and potentially have it so that there isn't enough pressure at another location making a fire harder to fight.Rjhawkin 18:36, 20 January 2013 (UTC)
To the point of those with a legitimate need knowing, actually they may not know. Firefighters on Mutual Aid calls may not know what the correct wrench is, in particular in cases where they are providing support in places that are significant distances from their home district (think Upstate NY firefighters helping out in NYC after various issues in the recent past.)

I favor adding this tag. there are potential applications of OSM in emergency response where documenting this could be quite useful. Nfgusedautoparts (talk) 17:41, 27 February 2014 (UTC)

Adjustments to fire_hydrant:type, addition of fire_hydrant:water_source

there is an easily correctable issue with the current configuration of fire_hydrant:type=*; the problem is that it inappropriately conflates true types (pillar, underground, etc.) with a water source (pond). i recommend that pond be deprecated as a type, and that fire_hydrant:water_source=pond,stream,main be added. additionally, i'd like to see two more specific types added, dry_barrel and wet_barrel. these are proper subtypes of fire_hydrant:type=pillar.

Potable water

I think it is good to tag if the water is potable (drinkable) or not; this can at times be useful. See for example color codes here.

I am currently using fire_hydrant:potable=yes;no;unknown; unknown would be the default value if none is specified.

Service Water Hydrant for Livestock Watering

Any sugestion how to tag these kind of "hydrants"?

They are used to fill mobile watering tank trailers (which are placed on cattle pastures).

amenity=watering_place, amenity=drinking_water or emergency=fire_hydrant doesn't seem to fit here. --Bmog (talk) 19:20, 12 October 2014 (UTC)

The function is similar to railway=water_crane ?
But the meaning is amenity=water_point.
We could add water_point=water_crane ?

New tags

Hungarian mapping community works together with water works and firemen. We suggest new keys for hydrants:

Kolesár (talk) 12:47, 19 March 2015 (UTC)

fire_hydrant:signage=marker
fire_hydrant:signage=plate
fire_hydrant:colour=* use colour=*
fire_hydrant:signage=missing : Why not something more general like fire_hydrant:issue=missing_signage ?

Clarification of diameter

Please make it more clear/plain that "diameter" refers to the source feed of the hydrant, and not the hydrant pipe (pillar) itself. The present phrasing of the second sentence is also ambigous: while the signboard has the diameter of the feed (like "H300"), the cast iron pillar has the diameter of its connection (like "DN80") - so should I read the pillar or the sign? ITinerisKft (talk) 14:52, 17 January 2019 (UTC)

You are right. Afer a brief consultation on tagging mailing list, we have verified that fire_hydrant:diameter was created for the diameter of the water main going along the street and in many countries you can read this diameter on the signboard above the hydrant.
When I rewrote fire hydrant page, I did an error: I confused the diameter of the water main going along the street with the diameter of the flanged connection between the water main and the hydrant, because here in Italy the diameter of the water main is not reported anywhere (nor on signboard nor on hydrant).
Now I will fix fire_hydrant:diameter legend, removing references to the flanged connection. Contestually I will remove fire_hydrant:diameter tags that I added, because they report wrong values. --Viking81 (talk) 18:05, 31 January 2019 (UTC)
In france, this is the internal diameter of the largest connector. The minimum size is DN80 (mean normalised diameter of 80 mm), but usually this is DN100.
There is no signboard, but the color of the top of the hydrant (or the reflector) give the diameter: White DN100, Yellow DN150.
