Anyone know the proper way to size a water softener?
So I was getting ready to buy a 48,000 grain capacity water softener when some guy on another forum told me if I want to size it properly for maximum hardness, I'll need a 64,000 grain capacity softener. My problem is that our water company softens water to about 11-12 gpg, and then during the "irrigation season" they dont soften at all, and the water gets to 30 gpg. So i suppose that's a little unusual. We have 3 people in the house, 4 baths (3 full baths) and none of our showers have more than one shower head. We're on city water. All the water softener companies I talked to suggested 48,000 grains. So I dont really know what to do and would greatly appreciate your help.
Thanks a ton!
