Yes indeed that would be the logical, professional and courteous way to go about things
Then why don't you do that instead of all the personal name calling attacks?
but unfortunately, certain individuals would rather argue with everyone and anyone that might have a differing opinion, experience or point of view, including quite often the OP, but short of everyone leaving or kissing this certain persons butt there seems to be no solution to the problem. After all, how do you argue with "God"
You make the decision to type what you type, no one else does that for you.
Sizing and programming a water softener is done with very simple math. Not opinions or points of view.
The math and formula used are both very simple.
I have used both for many years and have the formula and examples of the math used on my web site for anyone to use. Or, you or anyone else can prove me wrong using resin manufacturers' data instead of as you say, opinions and differing points of view.
Here in this and other forums, with the exception of the constant SFR sizing of a softener, Bob999 uses the formula and math. He is the only one that does. And you don't see me saying anything about the K of capacity or salt dose he suggests. IOWs, there's no argument because he is right; he's looked it up and not stating an opinion.
You and others here don't use the formula but then you don't size for anyone. You post about me and rarely say anything more than a short sentence to the OP if that; it's all about me and what I say and how I say it etc. etc..
The point is that using math and proving your point by backing it up with resin manufacturers' data etc. isn't arguing unless you don't understand how to use the manufacturers' data or spec sheets.
BTW, I support no PMs here or on other forums because no one else can learn from a PM except the recipient and if you can't say something in public, I don't think it belongs in a PM either.
