Hi Montanhès,

are you sure that "Font" is the real name of the water tap? 

Many new mappers think they have to give everything a "name". But many things do not have a proper name, and all the info can be conveyed with the other tags. See also

If needed, a "description" tag can be used. 

cheers, daganzdaanda
