The thing was reported as 'working, but discharging a (very) forceful jet' : hence an implied warning : 'take care and stand back if you don't want to get splashed'. 

Would have marked this as 'needs adjusting' rather than repair; searched for 'osm wiki repair' or '... adjustment' , then 'lifecycle' : no suitable tag found; 

Would we need to introduce a 'needs repair' tag, or would it be more appropriate to inform the care taker / operator (not listed on OSM, but usually on info panel near entrance. 

Would we need to include on OSM that the item needs adjustment? Would the operator regularly scan OSM for instances of 'needs repair / needs adjustment'  If it really splashed people, would it have been adjusted yet? 

The use of Description seems in line with the wiki, tempted to remove the 'state-of-repair' tag? Done, closed?
