I've read a lot of the posts on here, but hoping for some customized advice.
I'm trying to install a Fleck 7000 softener at our house. It will be the SXT model with 1" or larger internal flow but I think that does not matter to the core programming parameters.
It will be a 48,000 grain softener i.e. 1.5 cu-ft of 8% cross-linked resin in a 10" x 54" cylindrical tank.
The feed water is 17 grains per gallon. No iron and so no turbulator. City water. Large house, would like high flow/gpm for certain situations.
Will be using metered delayed regeneration mode.
I am planning to use a salt dose of 6 lbs/cu-ft, which means the resin will operate at 1.5 * 20K = 30K grains of capacity. Thus, I will program the control head with C = 30K.
I understand I can use either 0.25gpm or 0.5 gpm BLFC as long as the programming matches.
But what are the tradeoffs between these two -- how to decide and what does it affect?
I'm thinking of a 2.8 gpm DLFC but not quite sure how that is selected. Should it be sized and selected before the injector size, the other way around, or it does not matter? I see some posts saying the DLFC should always be sized larger flow rate than the injector -- is that true, and if so, why?
Same question regarding the injector size -- what factors decide its sizing? I see some information indicating that for my config, I should use a Violet #00 injector which is determined by the 10" resin tank diameter, but I am confused if that should be determined by the salt/brine tank diameter?
Also, I see a common configuration sold by some folks is with the #2 injector, which provides 0.5 gpm brine draw and 1.0 gpm slow rinse according to the charts/datasheet by Fleck. So how exactly do we pick the injector size -- what factors must it consider and in what order?
Thanks in advance!
