These tags are not specific to fire hydrants .. or anything else.

If you need to tag a specific check than possibly check_date:flow=*

functional_check=* is not specific enough .. and falls into the same problems as check_date=* and survey:date=*.
Note these are for the use of fellow mappers (i.e. they don't render), unless you make your own map.
