I had no idea softening water was so complex. I'm here because I'm trying to figure out if a non box store water softener uses less water when regenerating among other things. I won't go into the whole story as to why, but my small community is on one water treatment plant. The less water we send down the drain the better and we also want to reduce our water usage in general. As we've been replacing toilets, fixtures etc as we fix up our house, we go for the more efficient options always. I've heard that the box store water softener can use up to 50 gallons to regenerate and that could happen a couple times a week for our family of 4. That seems like quite a lot of water. Do the various softeners discussed on here use less? Is there an average number of gallons per regen? I read over sizing is an option but then does it become cost prohibitive?
My last question is about sizing. I've seen it mentioned on here about sizing then system, but I must have missed the formula so if anyone has a link. For info, we are a family of 4, 1500 sq ft house, 1 shower. 1 shower/bath combo, 2 toilets, sinks in kitchen and both baths and we are on a small community well. I used a hard water test strip from lowes and said we are a 15.
Sorry for the long post as my first, but wanted to paint a picture of our situation. Thank you in advance for any help you are able to provide.
