Water Softener - which one?
I need your help as I got wide range of recommendations from "professionals". Here's my info:
3,400 square feet home with 4.5 baths
4 family members
Water Hardness at 21gpg, no iron or any other issues
Currently have Culligan Hi Flo PV-45B which is 45,000 grains with 1.5" water line.
The Culligan has not been reliable to the point that I've decided to not to spend any more money on it after 8 years. I'm not sure if 45,000 grains is the right size since it hasn't really worked well for past 2 years.
Here's my dilemma where I researched all over the place.
If I go strictly by water hardness and # of people, the right size would proably 48,000 grain or possibly 64,000 grain. The problem with this is that the water line size of which the largest I found was 1.25" (Fleck 7000sxt) when my house has a main line of 1.5" (and I don't want to go Culligan again).
If I look for 1.5" line water softener (typically light commercial version), then the smallest grain capacity I found was 90,000 grain (Fleck 2850sxt).It also comes with 24" wide brine tank which takes up more of my garage space than I would like (vs current 18" brine tank).
I'm tempted to go towards Fleck 7000sxt just purely based on cost and size but I'm really concerned losing water pressure.
Fleck 2850sxt solves the water line size issue but 90,000 grain may be too much (=inefficient water and salt usage) and takes up too much floor space.
So which is better?
Or is there a 3rd option (other than Culligan) that I should consider?
Would I lose significant water pressure if go with 1.25" line for such large home?
Thanks in advance for your help.
