Fleck 5600SXT 64,000 grain Settings Review

[GoBears316]

Hi All: First time poster. I've looked at several threads and am hopefully close. I'm attempting to go for a good efficiency of both water and salt, but not compromise hardness too much. We don't need the water "super slick" (as we've not had a softener before) - but clearly don't want to "fowl" the resin or have short term gain for long term pain. Appreciate a quick review. Thank you!

Water: City water supply - 30 gpg hardness, 0.1 ppm iron, 7 ppb manganese

Softener: Fleck 5600SXT Valve (Pentair Brand), Injector 2 (label), Drain Flow 3.5gpm (label), 3/4" paddle meter, 2.0 cu ft resin, 64,000 grain capacity (assume BLFC is 0.5gpm but no label)

Household: 2 adults, 1 teen, 2 children. 160 gal use / day (12 mo avg per water bill).

DF - GAL
VT - dF1b
CT - Fd
NT - 1
C - 44
H - 35
RS - RC
RC - 160 gal
DO - 15
RT - 2 am
BW - 5 min
BD - 55 min
RR - 5 min
BF - 9 min
FM - p0.7

The less salt per cubic ft, the more salt efficient, but more hardness breakthrough.

Your current choice of BF=9 is good to match your stated objectives. You coud back that off to 6 for a little more salt savings.

Thanks for your quick reply Reach 4!

Just to make sure I'm reading this correctly - your good with all my settings above, but you think it would / could make sense to go down to a C of 36 and CF of 6 (so 4.5 lb salt) or are you suggesting 6 lbs of salt which would be a C of 42 and BF of 8?

Also thinking about water usage as I think they told me this would be about 70 gallons down the drain each regen cycle ..

The second: 6 lbs of salt per cubic ft of resin, with BF=8 is as lean as I would go to start for most people.

5*3.5 gallons for backwash.
5*3.5 gallons for fast rinse
4 gallons for brine fill.
55* (~0.65 depending on injector) for BD+slow rinse) (see graph in manual for slow rinse)
Add them up.
