Hi and merry christmas 
our water softener has been up and running for three weeks and is doing a fine job
5.1cbm = about 1341 gallons were softened in the time. Our pipes are 30-50 years old and have substantial limestone buildup. While the flow is still acceptable, there is not much headroom left.
In the first two weeks, i measured 3gpg in hot water and 2 gpg in cold water. After two weeks, both went down to less than 0.5gpg which is the minimum with my hardness drops (1 drop =1 gpg, or 0.5gpg in a bigger sample).
I was hoping for the soft water to dissolve some limestone. Since the hardness dropped from 2 and 3 to <=0.5, there is not much hope left.
What hardness should I expect from softened water that passed through about 60 feet of old pipes with lots of deposit, is there some hope that more CaCO3 dissolves after the initial success? I suppose the initial water hardness came from fresh calcite that wasn't fully hardened.
Best,
Detlev
