Hi, it's been a while since I've posted here. I always appreciate the helpful advice.

I recently changed the size of the injector, the BLFC, and the DLFC on my Fleck 7000SE water softener valve, as per advice I received here.

The old injector was yellow, I changed it to the correct #00 (violet) one. The BLFC was a .50 gpm, I changed to a .125 gpm. I replaced the worn out DLFC with a new 2.0 gpm one. I received these correct sizes from "dittohead" (thank you) via a link to the Pentair Service Bulletin #599 (the link doesn't seem to work anymore).

I would appreciate any advice on programming the settings properly and determining a good salt dose setting.

My system :

Inline Clack PVC Air Injector (to oxidize the Iron)
Well-X-Trol pressure tank
10" x 54" pH Neutralizer (85% Calcite, 15% Corosex)
9" x 48" Softener with 1 cuft of resin

My water basics :

(Hach test kits at un-conditioned water)
pH 6.5
Iron .45 mg/L
Hardness 15 gpg

Note : Hardness (after pH neutralizer) is +/- 17 gpg (ToBeConfirmed)

(Hach test kits after conditioning)
pH 7.4
Iron .05 mg/L (ToBeConfirmed)
Hardness 0 gpg


Current Fleck 7000SE Softener valve settings :

Feed water hardness = H-25
(I am considering changing the Feed Water Hardness setting to 20 but have left it as it is because I can't test the water after the pH neutralizer tank, yet.
Safety Factor = 0%
(Should I considering changing this?)

Previous Regeneration Cycle step times seem to be set up for the dF category as they were as follows :
Cycle Step 1 : Backwash = 9, Step 2 : Brine Draw = 59, Step 3 : 2nd Backwash = 4, Step 4 : Rapid Rinse = 9, Step 5 : Refill = 11

I changed the (brine tank) Refill time to 22 minutes to compensate for the smaller injector and BLFC.

I received this info from "F6Hawk" (thank you) at this forum :

"11 minutes times 0.5 gpm yields 5.5 gallons, times 3 lbs per gallon gives you 16.5 lbs per regen."

"22 minutes times .125 gpm yields 2.75 gallons, times 3 lbs per gallon gives you 8.25 lbs per regen."


I used the sizing calculator at : http://www.qualitywaterassociates.com/sizing.php
to check the "Total Grains of Capacity needed" and it looks like I need 18240 "Total Grains of Capacity for approximately once per week regeneration with a 24 hr reserve". The chart shows that if I use 6 Pounds of salt Per Cubic Foot of Resin then the "Salt Dose Capacity" will be 20000
grains and there will be 9 "Days between regenerations". It also shows that I will have 1053 gallons available to use between regenerations.


Should I change the Brine Refill time to 16 minutes? (16 x .125 = 2.0 gallons x 3 lbs = 6 lbs per regen) will this be correct if I want to regen only using 6 lbs of salt?

Are there any adverse effects to using this minimum amount of salt?
Are there any adverse effects to regenerating only once per week, considering I have +/- .45 mg/L Iron in my water?

Note : I will update the Iron and pH testing after I install a drain valve, post pH Neut tank, to see how much Iron it is able to filter out prior to going to the softener.


Thanks for the help.

I put your info into a spreadsheet. I would be glad to discuss any differences you would like. Im not a pro.

I used C=20 as you were thinking about, an I expect you will monitor the water and increase that if you see hardness leakage as you approach regen time. Otherwise I think my numbers match your pretty well.

System info (not programmed)

salt lb/cuft : 6
BLFC : 0.125
cubic ft resin : 1.0
Raw hardness : 20.0
Estimated gal/day : 120.0
Estimated days each regen : 7.6



Fleck 7000SXT Settings:

DF = Gal
VT = dF2b
CT = Fd
C = 20.0
H = 20.0
RS = cr
CR = 0.0
DO = 14
RT = 2:00
B1 = 8.0
Bd = 60.0
B2 = 5.0
RR = 10.0
BF = 16.0
FM = t1.2 (usual)

Thank you for the response,

The Master Programming Mode is a bit different for my Fleck 7000SE versus the SXT
as shown here http://www.discountwatersofteners.com/static-content/Fleck-7000SE-Quick-Startup-Guide.pdf

I copied and pasted the info from the above link.
My notes are in italics and in Bold



US/Metric Dislay Format
Example: Gallons [U--1] = Default
Metric [U--2]

Regenerant Flow
Example: Downflow [dF] = Default
Downflow Fill First [dFFF] (I have read here on this forum that this may be a viable option)
Filter [Fltr]

Regeneration Type
Example: Time Clock Delayed [7--1]
Meter Immediate [7--2]
Meter Delayed [7--3] = Default
Meter Delayed - Variable Brining [7--4]
Days of the Week [7--5]
*(Skip to Regeneration Time if [7--5]

System Capacity
Example: 24 Kilogram Capacity, Gallon Format [C-24] = Default (I will need to change this to 20)
180 Degree-Liters, Metric Format [C180]
*Not Applicable to [7--5]

Feed Water Hardness
Example: 5 Grains/Gallon [H-15] = Default (I will need to change this to 20)
25 Degrees, Metric [H-25]
*Not Applicable to [7--5]

Regeneration Time
Example: 2 O’Clock A.M. [2:00] = Default

Regeneration Day Override OR Day of the Week
Example: Regenerate every 7 days [A- -7]
Cancel Setting [AOFF] = Default (should I change this ?)
[Day X] (where X = 1 through 7) Set to Current Day
Note: OFF not available
*Day is incremented at midnight.

Regeneration Cycle Step Programming (1-5)
Example: 10 minute Backwash, in US Format, Downflow [1- 10] (mine was set to 9, change?)
60 minute Brine Draw/Slow Rinse, in US Format [2- 60] (mine was set to 59, change?)
5 minute 2nd Backwash in US Format [3-- 5] (mine was set to 4, change?)
10 minute Rapid Rinse in US Format [4- 10] (mine was set to 9, change?)
12 minute Brine Refill in US Format [5- 12] (I will change this to 16)

Note: All Above Settings Are Shown in Factory Default Settings Based on
Downflow Regeneration Type and US-1 Display Format.


Push Extra Cycle button to advance through all [D--X} settings

Note: Regeneration will occur on the day or days which are set to 1
(enabled) at the regeneration time which was set in the previous program
step.

Individual Day of the Week Settings:
[d--x] where x = 1 : d1 enabled regeneration this day
where x = 0: d1 disabled regeneration this day
[d7--1] = Default
*Skip to Line Frequency Setting if [7--1] or [7--5].


Flow Meter Size

Example: 1-1/4” Turbine Meter, US [F-82] = Default
1-1/4” Turbine Meter, metric [F21.6]
*Not applicable to [7--1] or [7--5]


Safety Factor
Example: 25% Safety Factor [cF25]
0% = No Safety Factor [cF-O] = Default (should I change this?)
*Not Applicable to [7--1] or [7--5].


Line Frequency

Example: 60Hz Line Frequency [LF60] = Default
50Hz Line Frequency [LF50]

Exit the Master Programming Mode

Note: Valve Calculates Programming Changes [CALc] and Returns to the
Service Position/Time of Day.





How would Downflow Fill First [dFFF] affect the performance?

I will change the System Capacity to 20 [C-20]
I will change the Feed Water Hardness to 15 Grains/Gallon [H-20]

Should I change the "Regeneration Day Override" or the "Safety Factor" settings?

In the "Regeneration Cycle Step Programming (1-5)"

Your suggested settings are :
B1 = 8.0
Bd = 60.0
B2 = 5.0
RR = 10.0
BF = 16.0

Mine were set by the installer 12 years ago.
For some reason, he set them each to 1 minute less than the Default settings :
B1 = 9.0
Bd = 59.0
B2 = 4.0
RR = 9.0
BF = 11.0 *

* I have changed the BF (Brine Refill) to 16 minutes

I saw "7000" and did not notice the SE.
Regeneration Day Override OR Day of the Week
Example: Regenerate every 7 days [A- -7]
Cancel Setting [AOFF] = Default (should I change this ?)
[Day X] (where X = 1 through 7) Set to Current Day
I infer this setting lets you choose a timed regen, so I think you don't want to change this.
Regeneration Cycle Step Programming (1-5)
Example: 10 minute Backwash, in US Format, Downflow [1- 10] (mine was set to 9, change?)
60 minute Brine Draw/Slow Rinse, in US Format [2- 60] (mine was set to 59, change?)
5 minute 2nd Backwash in US Format [3-- 5] (mine was set to 4, change?)
10 minute Rapid Rinse in US Format [4- 10] (mine was set to 9, change?)
I just wrote down what numbers I had seen suggested by others. As far as I can tell, these are generally not critical. If water is in short supply where you are, that could be a consideration. Is that the case? The Brine Draw/Slow Rinse rule of thumb is to use 4 times as long as it takes for the brine to be drawn down to where the check ball in the brine tank cuts off the draw. Too short could leave a salty taste in the earliest water drawn for use after the regen. If you wanted to really fine tune that number you could taste the brine near the end of the cycle.
Safety Factor
Example: 25% Safety Factor [cF25]
0% = No Safety Factor [cF-O] = Default (should I change this?)
If this is the same as the Safety Factor of the SXT, then I would think so. But then if it is the same as the Safety Factor of the SXT, then why would 0% be the default??? I would use 14% (1 / 7.6 = 0.1316) unless I got other info.
