Thanks for all the responses =). I tried a couple of more times, and I
think I like tea better with purified water than just plain tap water
-- even if it lacks almost any minerals. As I said, I don't want to
continue to buy bottled water after my familly has installed this
system -- it's a waste of money. I'll try different things out, like
seeing if the tea tastes better with virtually mineral-less water or if
a splash of regular tap water will improve the taste. Thanks!
