New softener help

[Kadex]

Finally bought a house and got away from renting. Really need a softener and trying to figure this all out. Here are the details and what I have come up with.

1.5 bath standard shower and tub.
no dishwasher but will get one eventually
1300 sqf home two adults
currently have old galvanized plumbing with buildup in pipes that will be updated to 1" pex to a home run manifold with 1/2" to each fixture and of course separate line for outside spigots.

On well water with in ground pump and pressure tank in basement
water tested as follows

No copper
Iron didn't show up on test I'm thinking if any there's 0.1 to 0.3
No Nitrate/Nitrite
PH 7.5
No Chlorine
Hardness 21 gpg

It's hard to figure flow rate at the moment because the lines are so bad but, I got about 1 gpm out of tub.

I'm thinking of the Fleck 5600SXT electronic meter on demand 40K Grain and set to regen every 1300 gallons. Would really appreciate opinions and other suggestions and let me know I missed any needed info.

Thank You

Looks like you are on the right track on the system and its size.
I my self would look at the 48k unit or 1.5 cubic foot with the 5600 SXT.
9lbs and 30k or about 1300
A little better bang for the buck on the salt.

Thanks for the reply I was kind of leaning toward the 48K but wasn't sure. Since the price difference is so minimal it would make more sense.

[Akpsdvan]

If the number of people in the home is to increase, the 48k would be better, if the water was to increase in hardness then again it would be better to handle the increase.

You will also get better salt efficiency from the larger unit.

Cool that's always a plus. When I first started looking I thought that if I got one too big it would take too long to regen, but I now realize that they have a few settings to adjust to what you need.
