    Yes, it will. However it's been suggested that Reverse Osmosis may lower the TDS to too low a level, unless it's mixed with some regular water. Many coffee machines have an auto-fill circuit which needs the water to be conductive for it to work. If the TDS is too low the water becomes non-conductive.

    Most people on here are probably using ion-exchange resin cartridges, which 'soften' the water (replaces the calcium with sodium), leaving the TDS pretty much unchanged.

The installation company didnt sell ro units so no vested interest, they said that carbon filters werenot adequate. Both surgery and home are on tank water, at home typically 12 ppm tds so i have great water for beer making and coffee. If i lived in SA with their shitty water i would install a ro system for beer and coffee.
      Why is SA water shitty for brewing beer or coffee?

        From a Crow Eater, sadly SA is well known for having water that is a little below par taste wise, however like most things in life, you get used to it.

          Everything that enters the Murray-Darling catchment finds its way downstream, but I believe the main effect is the saline groundwater in the basin that gets flushed down the Murray / Darling Rivers. Water extracted from the system for irrigation further increases the salinity of the water that makes it SA. That's my understanding anyway...I'm sure some SA people would have more details.

            If it's not shitty then why do you use tank water for brewing?

              Seriously though, I had a very bad experience with SA water about 20 years ago, was down that way competing in Australian surf titles and was advised not to drink the water. Being young, indestructible, and a smart arse ( dangerous combo) I drank the tap water and spent 24 hours shitting and throwing up, scarred me for life. When I travel that way now I drink only wine and beer (excellent down that way) still end up crook sometimes, doesn't put me off the grog though.

                Thanks for the information Bill So I guess I was grasping the concept of limescale fine then.. :P

                Jisgren, I would say that "damage control" is probably an ill worded description, as that implies PWS has done something wrong.. I'm simply standing up for the company I work for, which i (and the company) have a right to do on a public forum, don't you think?

                  I seriously doubt it was the water seamad, the stuff in some area's can be pretty hard but in my time (and I've been around for quite a while) I've never heard of any contamination that would produce the symptoms you describe.
                  Perhaps it was a crook stubby.

                    I hope you don't mind me contributing to the thread some more, i'm actually quite interested in everyones views/opinions and i'm always looking for more information from people such as yourselves

                    Water contamination problems - Giardia and Cryptosporidium There is a tonne of information out there about water borne parasites.. they are in all bodies of water with a source of protein in it. The national water guidelines state that there can be up to 5 of each of these guys in a 250ml glass of water before it becomes 'unsafe', but they also loosened regulations on the testing of the water for these guys back in 09, so there is a very good chance you copped a few..

                    They are also pumping CSG wastewater back into the top of the Murray Darling catchment - 8 olympic swimming pools a day is it? Lateline - 24/11/2011: Qld approves CSG water discharge

                    So that might be contributing to some of the water issues down there?? I'm not really sure but it doesn't sound too nice..

                      @Seamad - crook from tap water? How much sea water did you ingest whilst competing and how much alcohol did you also consume. Anecdotal evidence from a single data point is dangerous - i thought someone in the medical field might know that or are you a homeopath/naturopath/chiropractor?

                      I use rainwater for brewing to get more control by adding back the salts. I did win ANAWBS back in 2008 using tap water so apparently someone thought it was ok - cough 46/50 cough beer of show cough. A lot of more experienced and more awarded brewers than I use Adelaide tap water.

                      I also use rainwater for coffee but that means i only need to carbon filter it as it contains <0.1ppm Ca and Mg (tested by ICP-MS) so it saves me spending money on a filtration setup i don't need. I hope that people are testing their water before buying ion exchange setups.

                      Adelaide tap water gets a bad wrap due to the chlorine/chloramine content, both of which are easily filtered out.

                        Unfortunately, this is how a lot of the mis-information about water starts.

                        Perhaps someone would like to quote some actual statistics showing how many people have suffered any ill-effects from Australian potable water in, say, the last 10 years? If you want to pull the tolerances in for the sake of making coffee (or anything else for that matter) then you can test that you are getting the results you want from whatever products you choose.

                          you a homeopath/naturopath/chiropractor?
                          No , no ducks here.
                          I know anecdotal evidence is poor form but @ 10 of use got crook. We never drank alcohol during competition and had eaten at different places. We were not in Adelaide, I think it was Victor Harbour ?? The owner of the motel warned us about the water, those who hadn't drunk it were OK. There were more of us crook after the comps but that was certainly alcohol related.
                          I am sure your beers are tops , I have made your rye version of the golden ale several times and it's a cracker.

                          Getting back to coffee and RO, If I lived in a place where my kettle got a lot of scale then I would head down the RO path, cheap insurance if you have an expensive machine.

                            20 years ago and in Victor Harbour. That explains a lot - another world down there. I think they got electricty about that time...... surprised they had mains water. May not have been treated back then, many rural areas only got treated water in the last 20 years.

                            Back on topic - no scale in my kettle. Water in Adelaide just isn't that hard. I should dig out the data last time i tested both rainwater and tap water. Might help kill a few urban myths.

                              You need to check a few facts before posting DrS, Melbourne has the softest water in Aust and Adelaide the hardest see here Hard water - Wikipedia, the free encyclopedia no urban myths involved.
                              Victor Harbour is a city with a population of well over 10,000 situated approx 60km south of Adelaide, it's a busy holiday and tourist destination as well as being a popular retirement location, as far as only got power 20 years ago

                                Would have been late 80's, and it seemed the arsehole of the universe to us surfers paradise sophisticates.

                                SA seems to have a pretty variable water supply, from some discussions on AHB some areas have extremely hard water, whilst others have good water.
