AquaSafe RODI Setup Q's

[andsoitgoes]

AH. Okay - now, see, I don't have the faucet. What can I do to keep the water from flowing out the top? I have the holding container, but does that hold water for the aquarium or for drinking?

What is your blue valve controlled tube coming out of the DI unit used for? Do I not have enough stuff to do both? Can I get anything to stop the flow at like, Home Depot or something?
