    Who has two DI stages in their RO/DI system?  Is it worth it add another to my existing RO/DI setup (giving it two DI's)???

    Im thinking about doing it too Brandon... What ive been told is it is much more efficient since you can exhaust one di cartride 100% while with just one you start reading higher tds while in fact still have some life left in the di. That way you get 0 reading for alot longer since the first one picks up all disolved solids untill it starts to wear then the second picks up what the first begins to let through so the first one can be used untill its completly shot and then just put second in the first ones spot and new in the second spot. They also make an in line di that kinda does the same thing but not as efficient. Who has two on thier RO and is it worth it?
