    Default Water Softener, I'm learning but still a bit confused....

    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.

    The bigger the unit, the more water will be used the regenerate it, but it will have to regen less often than a smaller unit. You will use less water by getting an electronic unit vs a mechanical one. Clack and Fleck make very good electronic unit that you can program for a specific amount of discharge water. The average discharge per cubic foot of resin may be backwash 10 min @2.4 GPM, brine 60 min @ .33 GPM and final rinse 10 min @ 2.4 GPM. I did not mention refill because you will reuse that water.

    What model is it? Do you know how I calculate what size I need? Thank you for the reply.

    If money were no object, would an RO system do the job and "waste" less water?

    Reverse Osmosis - water to be treated is forced through a membrane to remove just about any impurities. In theory you would end up with pure water on one side of the membrane, and the impurities would go down the drain, much like when you sift sand through a screen, but apparently in practice you have to waste a lot of water to make that happen.

    Tom, any quantitative data on just how much water it takes to end up with one good gallon?

    I would need to know the water quality to answer. The water treatment plant should have or post the water test results. I need to know the hardness, iron amount and pH.
