hi wasp,
thanks for providing the info, i keep hearing conflicting advice on this issue so its hard to know which way to go on the issue, i'd be really keen to hear if anyone in chch has used both tap water and ro/di and what their observations have been. i've been looking at ro/di units but i'm not really sure what i should be looking for in a unit, and how they work in terms of how much water they produce, whether they only product ro/di when turned on or whether they continually produce etc. If anyones got some info on what to look for in a unit and how they work etc i'd be keen to know
