I'm not sure if I've shared this information previously, but in the odd chance that it's not been said before, here goes.
Anyone considering stainless boiler systems attempting to use it outside of either Sydney or Melbourne capital cities needs to seriously re-think their options - especially if it's LM. Other manufacturers might be more forgiving.
As for Brisbane, I lived in Tarragindi for 9 years and the water in our area was pretty naff most of the time (we had to install filtration on the drinking water), probably because we were up high at the end of the line and likely to have improved since. Luckily I used a simple copper boiler machine.
We have clients with commercial LM gear installed in their cafes, along with 2 stage filtration systems of the best quality available, yet the LM stuff has often failed like a wet paper bag.
I'm not going to dive into the detail and the statement above could be considered libel, but it's impossible to dispute the evidence ........LM failed to honor warranty on brand new equipment because it was installed outside of the metro area and the water is obviously (in their minds) toxic.
There is no way on earth you would expect to see holes in stainless boilers after 18 months......seriously, this is not how it's supposed to be and $6K later in repairs it's a painful lesson, even when the cafe owner provided detailed water analysis records from their local authority, LM just run and hide. It's almost as if their stainless was not real.
I've traveled all over Australia and the water in some regional towns is exceptional, others not so.
Also aware of commercial Synesso's, Slayers and other stainless equipment failing in regional towns prematurely - reasons are not always obvious upfront, but many can be linked back to water or some aspect relating to water when the post mortem has concluded.
If water in your area is not ideal, just keep it simple with good filters and copper systems.
