Sizing water softener for best efficiency
So I'm hoping to buy the proper sized softener to use salt efficiently. Hardness is 23 GPG, on city water, 2.5 bathrooms, 2 people in the house and pretty much never have guests. I've attached my actual water usage for the past 3 years below. Average has always been under 3,000 gal. per month, but there have been spikes. The Sept spike from this year is when I needed to use the hose to help water some small sod patches, so that is a rare occurrence. We also got a new more efficient washer late last year and have recently upgraded our dishwasher as well. not sure what specifically, if anything, caused the usage spikes in the past. I was looking at the Fleck 5600 SXT 40,000 grain w/1.25 cu. feet of resin. Thanks in advance for any help.
