He stated 1.5 cuft and 40K. 8 minutes refill is not sufficient salt in lbs to regenerate 40K in a 1.5 cuft or a 40K 1.25 cuft softener. That makes his programming way off, incorrect, wrong for either a 1.25 or 1.5 cuft softener.

And to come up with the math to prove that you do not need to know anything about the water analysis or how many people are in the house etc.. all you need is the volume of resin and the lbs of salt used and you have the K of capacity. In this case the refill minutes = x lbs of salt.

His slow rinse/brine draw time is way low at 25 minutes.

Here's what he said in his first post, #1 in the thread.

**Regen Draw time ?? **
I have a clack EE with 1.5 ft3 high capacity resin.

1 person household, but I bought a 40000 grain unit to size for the house.

water usage is 30 gpd. (5700 gal/6 months)

My ? is I have seen a 60 min draw time used by most posters here- My brine tank is empty 15 min into the "Draw" cycle. Does the resin need the rest of the 60 min to regen, or can I set my draw time to 15 min?

my times are:

13 min backwash

25 min draw

10 min backwash

15 min rinse

8 min fill

Set to regen every 1500 gallons of water use- I know this regens the resin every 50 days- but weekly or bi-weekly would be a waste of salt and water.
