I will see if he can take a picture, thank you.
I was wondering what you mean specifically by Ecosystem having a better network?
He means dealer network, they are the only people that can get parts for Ecowater softeners so you become dependent on them for all service.
A better "network" is the independent internet or local dealers you find in your yellow pages. There are more dealers to chose from.
Do all water softerners use the same science/technology? I am unclear on exactly the way that Rainsft works....crystals that trap positive ions?
Ion exchange is done by the resin in the softener. The resin sites are negatively charged and going to remove the positive charged ions in the water. Before the resin sites are full, the softener is regenerated with sodium chloride or potassium chloride brine containing positive charged ions that remove the calcium, magnesium, iron, manganese, lead, copper and such ions that were removed from the water, from the sites on the resin beads and it's all flushed down the drain.
Resin and tanks are basically the same. The most important/critical component is the control valve. They differ greatly and are the heart of a softener, so the quality of the control valve is the key to long service free operation of the softener, and getting soft water from the unit. I suggest the Clack WS-1 is the best control valve. It was designed/invented by three ex Fleck engineers with over 72 years experience at Fleck. Fleck is widely considered by many as having the best control valves. Most of those people have not looked at the Clack line of controls. Those engineers copied the Fleck one moving part in the water stream piston seals and spacers design and greatly improved it making it easier to repair with less expensive parts and requiring no special tools to repair it. All but the Fleck ProFlo requires one to three model specific special tools to reair them. The Clack line has the same warranty and out of over 800 sales to DIYers, I have had only 17 problems over 3.5 years now. So they have the same or better quality as the Fleck valves.
