Avoiding scale with pourover espresso machine

For some years I used Volvic water as recommended in another jim's guide. No problems & almost no scale in reservoir. Switched to Geyser Spring, also recommended, I think, because of availability & cost. After a few months, reservoir and water tubs crusted with scale. I have a Quick Mill Andreas Premium with heat exchanger boiler, so hard to descale. Ideas? Knowledge? (Everything I know and do I got from you all.) MobyD

You have to be careful with the Crystal Geyser Alpine water. It comes from seven different bottling plants, each with a different mineral content. You have to look closely on the bottle for the source, then check the numbers. Eric S posted a nice summary table of those numbers here: Blonding too fast. Profitec 700.
Note that the Johnstown NY source has a calcium hardness of 130 mg/L and alkalinity of 140 mg/L (in CaCO3 equivalents, of course.) That would scale.

If you are getting the Johnstown source Crystal Geyser, it would probably be fine with some dilution with distilled or RO water.
