Just out of curiosity, since this is a brand new build of your RO Machine, what are your plans for doing an initial flush of the system prior to actually processing any sap? Since I am in the same boat as you, I, too, will be doing something initially before introducing sap into the system but I just do not know what??? We are on well water here with no softener required (which is great as I hate the way that water tastes!). No discoloration of our sinks is present nor is there much, if any, sediment visible (I examined the tank of the toilet for this test). Of course, this water contains no chlorine. Given these conditions, is it safe to use our well water to clear this RO system of any preservatives or contaminates that may be present or should I opt for distilled water or is there another medium that is recommended? Also, how much flushing is recommended for a new system?

Maple season is just around the corner!!!
