There are two parts that work together for the brine draw.
There is the injector assembly with the throat and nozzle making up the assembly and the brine line flow control.
The brine line flow control on a number of units is a little rubber washer that is held in a retainer.
Within that retainer the little rubber washer can move around some but not much.
The injector assembly has different colors..
red is .26gpm , white is .33gpm , blue is .64gpm and the yellow is .89gpm.
The brine line flow control is more for the refill of the brine tank it can influence how the injector assembly works.
1. Water will follow the path of least resistance.
2. The BLFC can only be installed in one direction.
3. If the BLFC controlls flow out of the brine tank, then why would they make different size injectors which in my opinion will change the flow rate of the draw draw and not the BLFC.

The injector alone does not control flow, the BLFC button and the injector together do. And that is what I said that you have been going on about since, so Skip, you can believe anything you want to but it is the combination, not just the injector.
In the article link you posted, they don't mention the BLFC OR the Dlfc having anything to do with controlling slow rinse/brine draw flow rate but we know the Dlfc is involved. So go take out a BLFC and see if the brine water takes a shorter length of time to get to down to the air check or if it takes the same length of time or longer with the BLFC in.
BTW, if you asked some resin manufacturers to go over that article you linked to, I know some that aren't going to agree with the author/writer on a number of things in it.

The rest, I'm not able to follow what you mean to say. I'm correct, but why would I make a statement like that....?
Tell us how the BLFC controls the amount of salt used.
Have it your way but, if you have a .5 gpm BLFC button and an injector at or larger than say .5 gpm, and take the BLFC button out you'll get the brine down to the air check where the flow is shut off quicker/sooner than with the BLFC in the line IOWs you can't flow backwards through the BLFC button without reducing flow; it is impossible IMO.
Again, tell us how the BLFC controls salt use.
This thread is a shining example of how things get out of hand. The BLFC only controls flow out of the brine tank in that it establishes the minimal cross sectional area that the brine will flow through in the same way that the size of the pipes feeding the softener control the maximum volume of water flow through the valve unless pressure is either increased or decreased. Since the BLFC is a set orifice (yes you can change them) it establishes the maximum flow allowable given the venturi installed. In itself however the BLFC is not the determining factor, only a componant in the system. I can not for the life of me understand why time and time again we have to get bogged down in semantics or minutia that in the end have no bearing at all on the origional question and only serve as a platform to one up each other. In the end, picking nits will only get you a pocket full of nits which are of little or no value.
