I've been thinking of purchasing one of these as of late because of the tap water in my apartment. Can anyone explain how they work? Do these permanently plumb into existing faucets, or do you connect a hose to them, then transfer water into a water holding container to reconstitute it. The tap water is horrible, has a funny smell, and a horrible taste to it. I beleive it is ran through a water softener as my gH measures <1 degrees, and my kH measures 5.6 degrees. What brand would you recommend?
