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.

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.
