    Hello,

    I recently purchased a 1 year-old 1.25 cubic ft resin tank with 10% crosslink from a friend.
    I have a 3 bedroom, 2 bath house that includes a garden tub for 2 adults and 1 child. Our hose bibs, fridge water line and cold water outlet for the kitchen sink are separate from the rest of the house so they will remain softened. We consume on average 50 GPD per person @ 5.5 GPM. This number is probably less since it includes all the water from the sprinklers as well but this would not go through the softener. The house is new and has 3/4 inch pex piping with rough-in already completed for a softener in the garage.

    City Water
    Hardness 21 gpg
    Sodium 50.9 ppm
    Sulfate 78.1 ppm
    Chlorine 0.5 ppm
    Iron n/a
    Manganese n/a
    TDS 540ppm
    pH 7.7

    Any help would be appreciated.

    Is that tank new or used? Did you get a controller with that? If not, you will need one. If so, I suggest that you post a picture or two. Or do you know the make and model of the controller?

    I presume that when you said "separate from the rest of the house so they will remain softened" you meant remain UNsoftened.

    That water softener size is probably good for you. Was that what you are looking for?

    I suggest that you get a Hach 5-B softness testing kit to measure the effectiveness. With this you will be able to test that the installed unit is working and if your regeneration schedule is sufficient.

    It sat in my friend's garage for a year unused. The resin is still in bags. It came with a Fleck 5600 Econominder Meter. Also yes, I did mean to say that it would remain unsoftened. It was not exactly what I was looking for but he gave it to me for only $100 so I jumped on it hoping it would fit my needs.

    I've read through the service manual and the owners manual as well as almost every youtube video I could the past few days. And yes I am concerned that it may be too small or at least not as efficient as it could be.

    Have you plugged your numbers into Gary's sizing info (http://www.qualitywaterassociates.com/softeners/sizingchart.htm)?

    At 6 lb/ft^3 you get 25000 grains of softening. You figure to use 2*50*21=2100 grains of softening per day.

    So you use 7.5 pounds of salt every 11.9 days, but round down to let's say 10 days for the safety margin. That's nicely sized and efficient.

    1.25 ft^3 of resin gives SFR of 10... OK you are saying 2*5.5=11GPM , but you aren't going to be in sync with your peak use most of the time. And if you went over and got a little hardness bleed through, no biggie. It will be rare, and the water will still be almost soft anyway during that brief interval.

    Your new softener is almost ideally sized for efficiency. Be happy.

    Yes, I tried using the sizing chart but I thought I was missing information because it said I needed to call him but I thought he retired after Clack stopped online sales. This is what I got:

    3 people*50 GPD per person* Hardness of 21=3150 grains of softening per day.

    And it's at this point that I get lost because there is some much misinformation online. Some people divide the grains per day by the capacity of the tank and subtract a reserve. I had one that had me at a regen every 950 gal or about 6 days with 10lbs of salt. It's very confusing.

    So basically set the softener for 7.5 lbs of salt every 1500 gals of water?

    There are 3 people so it should be 3*50*21=3150 grains per day
    25000/3150 = 7.9 days rounded to 6 for safety margin
    6 days at 150 GPD = 900 Gal per regen

    Do I still use 7.5 lbs of salt? Why 7.5 lbs of salt when we did the math with 6 lbs?

    I was figuring 2 people -- missed the child.

    25000/3150=7.9days... 6 or 7 days with the reserve. If you want longer you could go to 8 lb/cubic ft... still pretty efficient use of salt. I would like to see how you came up with 6 days on 10 pounds (8 pounds per cubic ft of resin). 29000//3150=9.2 days minus the margin.

    So maybe you would have chosen 1.5 cubic feet if you were ordering from scratch. I don't think you need to calculate for 16.5 SFR... Close enough, don't you think? Exceed the SFR for a bit and you still don't get anywhere near the hardness you have now. And you have been getting by with no softener.

    I think that is demand-driven controller, so it measures gallons. The days calculation will be an estimate.

    6 pounds /cuft*1.25 cuft =7.5 pounds of salt.

    Edit. I did some reading -- the safety factor gets input by you figuring that it will do that many gallons and then regen the following night.

    So with 7.5 pounds, 1000 gallons (1035 gallons after allowing for the safety margin, then the granularity of the capacity wheel of the controller)
    With 10 pounds of salt, 1200 gallons (1230 gallons after allowing for the safety margin, then the granularity of the controller)

    I apologize, I did not use the correct terminology. This is a demand driven fleck not the day driven model. You would cut the gallons so for us one day safety factor would represent 150 gallons.

    So I was putting everything together and I guess I did not put the top basket on well enough...it snapped off and dropped to the bottom. I used some fishing line and hook to pull it back out without messing everything else up. I am now just waiting for the falcon connectors to come in and do some pex plumbing this weekend. Thank you!
