Looks totally wrong. Should feed from right to left... Far right sediment filter (first), then middle carbon block (second), then ro
membrane (top), then ro
water to di
left (third), waste to drain... then from the di
left to the holding reservoir.
I also prefer to run water through each chamber separately for about 15 minutes before setting up, to make sure no preservatives or manufacturing residue from entering the next chamber.
Also - the lines are generally color coded for easy recognition... Blue for filtered water, red for incoming, and white or black for waste.
