JoshD - you mentioned that the cost of RO
is high due to the waste water. As melosu58 mentioned, there's options to use that waste water, but even if you put that water down the drain, it's still not that expensive. Assume an average cost of $0.002/gallon (quickie internet search, just for water - no sewer, etc), and lets say you use 100 gallons of RO
water per month. If you're really at a 1:8 rate, then you're wasting 700 gallons of that water. And at 0.002$/gallon, that 700 gallons amounts to $1.40 per month wasted - for 100 gallons of pure water for the tank. Not sure of your tank size, but from a $$ standpoint, water is really cheap. (Just talking about the monetary aspect... not the whole "waste" aspect. Harder to put a dollar value on that.)
Also... I'm not an expert, but 1:8 waste ratio seems pretty high. Have you looked into boosting your incoming pressure if it's low? Or replacing the RO
