    Re: Tap water or distilled water in coffee machine?

    OK, time for me to jump in with a few comments.

    As previously stated when this and similar discussions have occurred terms really must be defined. Despite several comments to this effect here yall have not done this. Hence youre most likely talking about different things when using the same terms.

    For purposes of this discussion Reverse Osmosis (RO) water refers to RO water produced with over-the-counter home RO units.

    Reverse Osmosis (RO) water != Pure water

    Reverse Osmosis water (I suspect the same is true for most Distilled, and De-ionized waters available to home users also.) is not pure water! There-for any discussion of the effects that pure water have are meaningless when discussing RO water!

    Pure water = H2O  [b]With nothing else present in the solution!

    The RO membrane will remove (most) dissolved solids. Among other things it does not remove dissolved gases! Ergo RO water is not pure water! Therefor any discussion of the reactivity of the H2O molecule is only part of the equation of the reactivity of RO water. To claim that RO water is non-corrosive/reactive because the H2O molecule has no free ion(s) is at best an uninformed comment and at worst disingenuous.

    So, with all this said is RO water bad for pipes and boilers made from such things as copper and brass and therefor bad for espresso machines? Yes.

      Well put Java "with the clear mind" phile.

      1: Water with minerals / irons and other extras tastes GREAT  

      2: Some of the "extras" are not kind to our bodies and or equipment...  

      3: There are ways manage the un desirables without compromising TASTE or the EQUIPMENT.

      Any thing else just falls into a Conspiracy theory where no one wins...  :-*

        Yes, this thread is getting us nowhere

        I have glossed over the dissolved gases (and many other things), I was wondering when it would raise its head. Ill just leave with the comment that you need special treatment to remove gases. Neither distilling, deioinsiation or RO will remove dissolved gases but they are also present untreated water that they have been produced from so they are all on the same foot in this area

            So from what I have read we are going to agree to disagree about the effect of "pure" water (RO etc) on the internals of a coffee machine but nobody should use it because it is a negative on taste of the resultant coffee, hope I have read it right.

            It is a fantastic discussion I love it when "the accepted wisdom" is challenged as there is much in the world that people accept because everyone says so (ie the world being flat).

              What are you trying to say... It is FLAT or we would fall off...

              AS to coffee machines..

              1: We all appear to agree that TASTE is important..

              2: Equipment maintenance is up to the user and any problems that might be had: with the supplier.  However the supplier also have a strong position and regardless of your perceptions / beliefs....  They will make the call if it comes to a disscussion as to if the unit has been used / maintained in the manner they recommend.
