Reply To: Water fountain on Shabbos

Sometimes there is no one to ask if the water fountain is ok, so how would I know if it’s ok on my own? Most water fountains don’t have a visible plug, so you can’t tell if it’s unplugged. Would there be something about the water fountain, aside for the plug, which would help me identify if it’s a mechanical one? Sam2 said about the “perfect stream”-but is that true?
