Help me size water softener
Hi, I need some advice regarding correct size of water softener.
A little bit of background info: My house is 4000 sq feet wiht 4 bathrooms. There are 2 adults and 2 kids and our average monthly usage is 300 gallons of water based on water bill. Some of this water used by sprinklers, but I am not sure how to calculate that portion out. Water hardness is 35 gpg.
I need advice on which size of water softener would work for me: single tank Fleck 7000 96K grains, 3cu ft or Fleck 7000 110K grains 3.5 cu ft . Or should I consider some other size of softener like 64K or 80K or different valve (like Fleck 5800 -- I want to stay with Fleck). What about 64K, would it regenerate too often based on my water usage and hardness? Thank you very much.
