This question deals with someone who has a cup of a drink and carries it around all day long, possibly refilling it, etc. I am wondering, for someone who drinks from a drinking fountain every time he walks by it, should he make a new bracha each time he drinks? Does it matter how much time goes by between episodes? What other considerations are there?
I heard from a student of Rabbi Yisroel Labkowski (the Rabbi is word-for-word boki in Shulchan Aruch, you start reading anything, and he can finish it) that he said there are 5 reasons in halacha why you are not allowed to drink directly from a water fountain.
I don't remember all 5, but the one I do remember is that you have to see the item you are making a Bracha on, and the water you drink from a water fountain is not the water you see when you say the Bracha.
Assuming you avoid this, or your LOR tells you it is not a problem, the answer there would seem to apply equally to here.
