Hi Jeff, I also live in Vegas. I also shopped around for water softeners and it was stressful to say the least. The seller that you mentioned was really aggressive and would call me at 10PM at night (this was in April 2020).
Anyways, my research on macro-porous resin is that it is unnecessary for municipal water and actually supposed to use more salt. We have chlorine in Vegas but check out the reports and do your own test, it's not as high to warrant macro-porous resin and if you us carbon to filter out the chlorine before it goes into the softener, then you wouldn't have to worry to begin with.
Jason is a really smooth talker, but after going back and forth. I realized what some of what he said wasn't true. I think the main being that you use less salt with macroporous resin and his expertise on other mediums on anion and KDF. I was going to write a bad review on Yelp last year, but I actually was afraid to. Towards the end of my shopping around, I gave him the courtesy to let him know I was going to someone else. He then dropped his system another $500-1000 I don't remember. But maybe it was because of the pandemic. Then when I told him no again, he'd ask why. HE started to berate me and my decisions. (He also critcizes these DIY forums, which I've brought up)
I will say in terms of sales and followup, Jason is always first to call and followup and some of the other companies take a while to respond or it just seems like they aren't as hungry for business... but overall there are at least 4 other companies I'd choose before Clear Water Technologies.
After getting my softener else where, some of the stuff he said simply wasn't true (like my water pressure would be bad if I went with another company).
In short, after hours and hours of research, I called him out on a few inaccuracies. I'm, sure he's gotten better now, looking his has 32 positive reviews on yelp.
Overall all the water softener people in vegas use Clack Valves. Most use 10% crosslink resin except fro ClearWater which uses 16% Macroporous Gel.
Next is the extras. If you want to get a carbon to take out the chlorine. it should not be mixed with the resin. This is either seperated in a seperate tank, or a tank on top of a tank, or the vortex system. Then there are additional "Stages" which is marketing for different mediums.
Anion resin I learned may not be necessary for Vegas municipal water and since it is another medium, may cause more hassle in the long run. People just started adding more and more "stages" and mediums or more expensive mediums (eg catalytic carbon) to compete themselves with others.
Also costs involved, you don't see then actually pour out the mediums in the tanks. I don't know if this helps but I hope it does.
