  • Adelaide water quality

    After a year of buying bottled water I decided to test my water as Adelaide water is supposed to be very hard. To my surprise The test strip said my water was around 100ppm hardness. My water is filtered through a Puratap filter which doesn't do anything for water hardness. I then tested the water from the machine which has an in tank water softener and that showed a hardness of around 50ppm.

    I'm thinking of upgrading to a new machine next year to a HX machine. I have read that the new stainless steel boilers really need the Brita c150 finest filter to keep the stainless steel in good condition. Before replacing my Puratap I was wondering what the taste of the water is like with these filters? I hear it's great for espresso but haven't heard anything about using it for drinking water. Here is a breakdown of my mains water from water S.AYour local drinking water report.pdf

    Plenty of discussion of various filters here.

      Yep, I read through that thread. It's a few years old.

      I use a Brita C150 Finest cartridge under my kitchen sink, feeding our benchtop filtered water tap, used as drinking water. We have no concerns with the taste.

        Other water parameters to consider are pH and chlorides (Cl-) which should be within certain ranges to minimize the risk of stainless steel corrosion. Manufacturers often specify these ranges for their equipment, which can guide the choice of filtration.

          Is there any safe bottled water for stainless steel boilers? I was using mt Franklin bottled water previously and while the hardness is very low I'm not sure about the pH as I couldn't find anything online.

            Pureau is safe for all machines to my knowledge

              Really? I thought Pureau was RO Water and had no minerals...

                There's a couple of other threads around with multiple people reporting that a manufacturer / machine supplier instructed them to use it if they couldn't install suitable filtration

                  Found a few posts with people saying Pureau water is good for machines. It's strange tho looking at the mineral content it has 0 minerals which I always thought was bad. I seen a few people using Pureau water as a base for making brew water.

                    Adelaide water is not as diabolical as people claim.

                    I've been using unfiltered Adelaide water in espresso machines for over 20 years without any problems.

                    Have your machine serviced regularly or do it yourself if your handy, the money you save on filter setups and bottled water will more than pay for servicing.😉

                      I have never been able to work out how the same water could produce both Coopers and Southwark.
                      Sublime to disgusting.

                    Without my Puratap the water tasted horrible but the hardness is really not that bad. The thing that concerns me is the new stainless steel boilers which pretty much all new machines come out with now. I have read only the brita finest filter is suitable for these boilers. Also looking at my local water report it's very high in chloride which seems to be a problem aswell. ATM I do service my machine (Lelit pl41tmp) but it's a single boiler machine so it's alot easier to descale and such.

                      Cant comment on stainless, all of my machines have had copper boilers.

                      Seems odd, stainless is meant to be superior to copper but has more issues.🙄

                      Hmmmm, just checked, seems most of the Bezzera machines still have copper boilers.🙂

                        Apparently SS is more sensitive to acid damage from low PH water.

                        Seems so. The Bezzera Magica looks like a great machine for the price.

                        I'm a big fan of Bezzera machines, mind you I am a little biased.

                      From my understanding, yes. The PH needs to be correct and there can't be high amounts of chlorides in stainless steel.

                        I understand that completely pure water can be problematic because the water level sensors in certain boilers require some dissolved solids (ions) in order to function correctly. Also, it seems generally accepted that a certain level of hardness (carbonate) is required in the water to optimize the flavour profile of coffee. This is why users of reverse osmosis systems re-mineralise their water in a variety of ways.
