Normal filtered water should be fine.. The over processed / RO water is not suitable for many reasons...Originally Posted by 4F545542575E4C52483B0 link=1256363051/0#0 date=1256363051
While you can re introduce the required minerals etc the trick is to not take them out in teh first place.. Thus *Filtered water and if possible a softener cartridge..
NOTE: Just because you have a filtered water tap... Does not mean it is filtered.. The filters etc need to be in a working condition..
