Bottled water tastes fairly crap. But potable/tap water ...even in a part of Australia with good infra (i tested my tap water to have 17tds) tastes like a combination of metal/bleach. It is "hard" in the chemistry sense...and difficult to chug (the body doesnt like large amounts of it too quickly) Once youve drunk ph adjusted (higher alkalinity) from a 4 cartridge RO water filter...everything tastes like shit.
