I am wondering what the recommendation is for the grains per gallon (gpg)
setting of a water softener.
Our city states the gpg is about 23, but a few years ago I had Sears do the
water test and they said that the sample (after it had went through
softener) was, if I remember correctly, 27. Thus I changed the setting to 25
on my softener since after that it requires increments of 5.
Today I had the water retested and Sears said the hardness was about 3 gpg,
which would mean the actual gpg before the softener is 28 gpg.
I called our city water department and spoke with the engineer who said it
is 23 gpg and that getting the gpg to 0 is not recommended as water that
soft is also not good for pipes, etc. His recommendation was to keep the
setting at 25 since it was showing about 3 gpg.
I called GE whose recommendation is to go 5 above the actual gpg and they
suggested going from 25 to 30 gpg.
So, knowing that my softener goes increments of 1 until 25 then increments
of 5 after that, what is best?
Thanks for your comments,
