    Hi everyone,

    I had a fleck 5600sxt 53k grain water softener installation done.

    I’m not sure if it is actually working. I’ve got test strips but the colors are hard to read and to my guess it’s reading 7-15 gpg.

    I have my settings on my digital gauge set to:

    Gal
    Df-16
    C-53
    H-26
    Rc-0
    Do-14
    Bw-10
    Bd-60
    Rr-12
    Bf-21
    .7

    Please help

    Do you have a 12" x 52" or 13" x 54" tank, or what? To measure the diameter, you can measure the circumference with a string, and divide by 3.14.

    Well water I presume. You want to get a Hach 5-B to measure softness for both raw water and softened water.

    Are you saying that your test strips seem to show your softened water to be 7-15 gpg?

    Make sure you test the cold, rather than hot, because there is a delay in the water working its way through the WH tank.

    I let the cold water run for a bit before I tested with the strips. Yes, my guess from the strips is 7-15 gpg...multiple tests done.

    City water.

    Tank size is:

    Also, my water level is about 2feet in my brine tank is this normal?

    How do those settings look to you?

    I will get the tank size

    Most 5600SXT softeners have a 0.5 gpm BLFC. You could check, because you could be an exception.

    You have presumably been using a lot of salt. So if you are not getting softening, check to make sure that your bypass valve is not in the bypass condition. Otherwise lack of softness is not a setting problem for you. If you are not getting soft water, I suspect you have a hardware problem. Do you know how often you regenerate? How old is your system? How much water is in the brine tank, and does it get sucked out during the BD cycle? That is worth checking. It should get sucked out about 15 minutes into the BD cycle.

    Until you get your hardness kit, I suggest these:

    System info (not programmed)
    salt lb/cuft = 8 ; A choice ( efficiency vs capacity)
    BLFC = 0.5 ; Brine Refill rate GPM
    cubic ft resin = 1.5 ; ft3 resin = (nominal grains)/32,000
    Compensated hardness = 16 ; including any compensation
    People = 2 ; gallons affects calculation for the RC setting
    Estimated gal/day = 120 ; 60 gal per person typical calc
    Estimated days/regen = 18.75 ; Computed days including reserve

    Fleck 5600SXT Settings:
    DF = Gal ; Units
    VT = dF1b ; Downflw/, Single Backwash, black cam
    CT = Fd ; Meter Delayed regen trigger
    NT = 1 ; Number of tanks
    C = 36.0 ; capacity in 1000 grains
    H = 16 ; Hardness-- compensate if needed
    RS = rc ; rc says use gallons vs percent
    RC = 120 ; Reserve capacity gallons
    DO = 30 ; Day Override (28 if no iron)
    RT = 2:00 ; Regen time (default 2 AM)
    BW = 5 ; Backwash (minutes)
    Bd = 60 ; Brine draw minutes
    RR = 5 ; Rapid Rinse minutes
    BF = 8 ; Brine fill minutes
    FM = ____0.7 ; https://terrylove.com/forums/index.php?attachments/img_fleck5600sxt_flow-png.31592/

    @Reach4 It says .50 gpm. 1.5lb salt/min.

    I have only had this for about 2 months-ish. Hasn't been using that much salt, I've been playing with the setting becuase I assume it wasn't working correctly, thus me coming to the forum.

    The recent #'s I gave you caused the brine tank to fill with water about 2 feet high. (Is that too high?)

    When does the BD cycle start? Right away? I can do a re-gen when the family is sleeping and check.

    Family of 6-would this effect my RC setting?

    I've adjusted my settings in accordance with your suggestions.

    It's high enough that it might have been the brine safety float that limited the fill.
    It starts after the backwash (BW).

    @Reach4

    What should I do about the water level-or will your settings change this?

    I would just watch without removing the excess water. The brine will probably take longer than the 15 minutes to get drawn out. I am wondering if it gets drawn out at all, since you are experiencing insufficient softening. See how far it gets and in what time.

    It is not clear if the 7-15 gpg is the hardness of the unsoftened raw water, or of the softened water.

    A 10" X 54" resin tank is appropriate for 1.5 cubic feet of resin. 1.5 ft3 resin has a total softening capacity of 48,000, not 53,000 grains. The resin's total capacity is not the Capacity setting that is to be programmed. For 1.5 ft3 resin, the usually recommended Capacity setting is 36,000 grains which will require only 12 lbs salt per regeneration cycle which Reach4 has indicated in post #5 above.

    Your initial 21 minute Brine Fill setting X 0.5 gpm BLFC = 10.5 gallons of water that entered the brine tank. 10.5 gallons will dissolve 31.5 lbs salt. As mentioned above, the amount of fluid in the brine tank could be less than 10.5 gallons if the fluid level in the brine tank became too high which caused the safety float to be raised during brine fill.

    To draw in all of the brine currently in the brine tank, recommend confirming the brine level is lowering during Brine Draw. Once it becomes obvious the brine level is dropping, unplug the electrical feed to the softener for approx 2 hours to allow extra time to draw the extra quantity of brine and provide sufficient time to rinse the resin. After the 2 hours, resume electrical service to allow the softener to automatically complete the remainder of the regeneration cycle.

    I did a re-gen cycle and during the Bd cycle I watched it for about 20 minutes. The water level dropped about 7 inches. It’s now below the salt.

    The purpose for extending the BD and Slow Rinse time (both functions are combined as 'Brine Draw') this time, is to ensure sufficient time for the large amount of brine to be transferred to the resin tank so the brine will have ample opportunity to regenerate the resin's capacity and also, to ensure there will be sufficient time to thoroughly rinse the resin afterward. If the slow rinse time is insufficient, the water will remain salty directly following regeneration.

    Because 1.5 ft3 of resin has a maximum capacity of 48,000 grains, programming 53,000 grains means regeneration was occuring well after all of the resin's capacity had been depleted.

    I appreciate you taking the time to explain this.
    I’m doing what you said now. I’ve changed my settings to what @Reach4 suggested above.
    I should get my testing kit within the next couple of days.

    Random question- how full am I supposed to fill my tank with pellets?

    Full-up is OK. Having some salt above water is OK. Anything between is OK.

    Hi everyone. Hi @Reach4 & @Bannerman .

    Well I learned alot today. Feel kinda dumb.

    I learned that the water that goes through my loop in my garage does not go through my kitchen sink (cold only, hot side slowly stops coming out) or refrigerator water line. I shut-off the loop and went and tried every single knob in the house, including dishwasher and washing machine.

    I've been testing the water from kitchen sink this whole time.........sigh.

    So, I finally got my Hach 145300 Total Hardness Test Kit, Model 5-B from Amazon today and I tested the water that is not softened (loop off, kitchen sink) I let the water run for a couple minutes before I took a sample. I did the test from the kit 3 times. I got a 10,11,10. According to the box that many drops equal hardness.

    I made sure my softener handles were NOT in bypass and I turned my loop in the garage. I took let the water run for a couple of minutes before I took a sample of the water from bathroom tub, I tested from the kit 3 times, all 3 times were a "2", after 2 drops the water inside the vial turned blue immediately.

    Thoughts?

    Hi @Reach4
    I update my settings back on the day you told me to.
    Are those settings a good balance for salt use and softness?
    Thanks,

    Usually. Watch the display gallons remaining, and when it is getting low, test your water with your Hach 5-B test. If the hardness is such that one drop turns the sample blue, then you are doing well. If you start getting hardness as the countdown gets low, some compensating adjustments would be called for.

    Does it feel nice?

    Ok, I’ll do that.

    It feels good. I think it could be a little softer though.

    The readings I got from the raw water is the same as the water company told me was the average. They said the high side will be 5 more grains.
