RO-DI

[Boga]

How much DI mean to the water quality? I am runnnig a five stage RO, TDS at output varies between 6-11 ppm. I understand that DI could bring that to near zero. Have you noted a difference? Is it worth to invest in a DI addition?

When I first turn mine on I measure the TDS input going into the DI (due to TDS Creep).  As soon as it drops to about 25-30 in I switch it over to measure TDS out and drop the hose in my mixing bucket - its always outputting 0 TDS water by that point.
