Well, the Rainsoft Corporate address above never replied. I was expecting at least a call from a local sales guy. Just for laughs, I walked into our local RS location, explained that I needed a new Tri-Guard for my old brass valve unit, and the very friendly and knowledgeable lady promptly walked to the back and got one. $37.50 please. She went on to explain that she had all the other parts in stock except for some timer parts, and to stop back if I needed something else. No sales guys, no pressure, just a friendly, seemingly well trained individual. The unit seems to work fine, it's installed and working.
I do have a setup question though. How do I adjust/set for hardness? What sets the speedof the brine draw? I mean I see the setting for water into the brine tank, it's set at 4, and it takes about 25 minutes to draw it all off. It seems related to the orfice behind the drain line fitting?
Again, thanks for all the help...
