When you change out the resin do I need to run a certain amount of water through it?
I would toss the first couple of gallons just to be safe. Won't hurt anything. I do know you rinse the first stages wo the membrane then the membrane wo the di to flush out any preservative to save some of your di like 5 percent they say.after all that yes flush out your di.
