Softener Sizing Help

I don't think either of us has the right to state incorrect opinions when giving someone advice. The CV of a control valve has everything to do with its use on a given size of softener or filter. And it seems you don't know that yet you disagree with me on sizing correctly.

You have been banned here at least 3 times, IMO that should tell you something.

Culligan, Kinetico, US Filter, Ionics, Sears. None of these companies size their units based on SFR. Why is that?

You need to check their spec sheets.

There is nothing to add to this thread.
