Anything above 10.5 grains per gallon is classified very hard. That is not a sales figure — it is what comes out of the tap here.

So here is the part nobody prints — what the standard package does not cover.
Illustrative example, not a quote. Your final installed price is confirmed by the licensed contractor based on site conditions.
