La Marzocco Linea Mini running the wrong water softener.
In general, if you don't go RO, you need to choose between taste or machine life.
KH filters taste better, for sure - but a lower pH and clorides in water near and above the boiling point makes the water aggressive and is a path of destruction for your espresso machine.
All brass will become crisp as corn flakes, glue with be "eaten" by the "unsaturated" water.
I know dH filters are more bland and heavy tasting, but at least you are only drinking water and coffee - and not also you espresso machine... #waterfilter #watersoftner #youaredoingitwrong #lamarzoccolineamini #lamarzocco - 2 hours ago
