Setting Up RODi

[Jgomez324]

I was told to let a few gallons run out before using the RO water. Is this true?
I don't see it say that on the instructions.

If you have RO only, you'll want it to run for about five minutes to flush the break-through that occurred when sitting without running.

If you have RO/DI then you'll ideally want to run the first five minutes to waste before running though DI. A simple three way valve allows you to do this.

Either way, I'd suggest picking up a TDS meter to monitor levels.
