Apparently, I cannot spell at all on Sunday evenings :D. Should read: reverted my previous changeset which mistakenly deleted a pump completely+updated its details; added a drinking fountain.
Context: the pump at the Marktplatz is dismounted, and I have deleted the corresponding node completely while surveying with Streetcomplete. However, even the pump is dismounted, the well is still there, so I rolled back my previous changes and corrected the tags.
