The fridge only requires a certain PSI for the ice maker. I "should"
be OK but will check.

I've started the run. I will have to open up one wall to get the
tubing through a stud that I can't reach otherwise but other that that
It's pretty straight forward... not counting replumbing the softener,
rebuilding the brine tank, and rewiring some stuff while I'm at it!

thx for the feedback.
