Adding drinking water spot (with photo).

Change drinking_water=yes and adding drinking_water:legal=no as the fountain has "no drinking water" but it's drinkable (at your own risk) according https://wiki.openstreetmap.org/wiki/Key:drinking_water the recommended way.

Adding photo and description of apprx. amount of water flowing.

It's marked "no drinking water" on the fountain on site, therefore drinking_water=no, but adding quality=drinkable as it's drinkable (I did). Public water sources in this region are scarce, so worth to mention.

Just adding a tag (bottle = yes).

In Hauenstein are no drinkable fountains/water sources (all marked "no drinking water") - but they are drinkable at your own risk, so I mark at least one prominent water source for hikers.
