If you are doing an import you should check beforehand if there is

I do a proximity check: however there is a problem in that legitimate
drinking fountain spacing can be far smaller than normal GPS or air
photo resolution. The proximity conflation can produce false results.
It is usually impossible to pick out the fountains on even the best air
photos (and OSM does not have the best air photos).
