Soooo many of these posts asking about water softeners..... but here's my opinion as a seller and troubleshooter of all sorts of softeners:
1. All salt softeners work the same way. Resin in the tank removes hardness. Every xx,xxx gallons, you regenerate with salt to remove that hardness and start over again. There's not really one that provides "softer" water than another.
2. Kinetico gets the job done without electricity. IMHO, they are VERY expensive for what you get. If you want to pay a higher price to get soft water, go for it.
3. Fleck is the big name in softeners. Mostly, your local soft water company buys Fleck softeners and silkscreens their logo on it. That's cool. Lots of people can work on Fleck softeners and repair them. I'm not a big fan of their heads, but some are.
4. Clack is very similar to Fleck. I like their units a bit better. They seem to be more reliable. As with Fleck, most resellers silk screen their name and logo on them. I'd put a Clack in my home if I needed soft water.
5. Home Depot sells softeners. Want to buy one there? Go for it. Let me know what they say when you call for help troubleshooting your softener.
80,000 grains seems big for a home softener to me. I don't work with residential, but I think they are oversizing it. That'll flow about 17 gpm.
