I tried to edit the above post but the machine won't let me. Re-reading it, it seems to be a bit snarky which was not my intention.
I was probably wrong to launch into the details of ion contents etc. For our purposes, a more important figure is the hardness and as a rough estimate in Melbourne water you can assume it is half the TDS or less, making the water quite soft.
The comment about chloride was a cover all bases thing: stainless steel doesn't like elevated chloride levels.

Not sure what you want to know.
TDS by itself doesn't tell you very much (except that logically a low TDS means that ion concentrations are also low).
You specifically asked whether you needed to treat the water to keep your machine "good". At the ion concentrations that are typical in Melbourne water with the TDS figures you mention, you don't need to.

Hi Lyrebird
Could you explain further your inferences. Ie Are you saying that TDS above 50 is contributing to scale ( using the 54 total from above). I think the wider used 'ideal' measure is up to 75 ppm - but i am not sure about the chloride values. ( I am definitely not a water chemistry boffin!!)
I am not trying to be narky here,,, just interested in this. Cheers darryl

That's a pretty typical analysis for Melbourne water, I used to live in Willy and got similar results routinely at my kitchen tap (I have my own TDS meter and access to a winery laboratory).
The total level of scale forming ions (Ca, Mg) will be around 5 ppm and chloride under 10 ppm so there is no need to do anything to protect your machine even if it has a stainless boiler.

Water filtering and treatment
Hi all,
I did search but couldn't find anything, apologies in advance if this has been discussed.
I just ordered a new espresso machine and want to keep it good.
I tested my tap water (Western suburbs) and got 54ppm and 7.95 pH.
Do I need to filter out treat my water for my machine?
Is there anyone else with similar results? If so how do you treat or filter water before filling your espresso machine?
Thanks in advance.
