RO/DI question

[Greybeard]

Sorry @Greybeard, I know this is an old post, but I’m hoping you can help me a bit to understand where to put a permeate pump in a brs drinking water/reef RODI system. You say that the permeate pump replaces the auto shut off valve. Does it get plumbed into the same spot that the auto shut off valve in a typical BRS system is found? And do you place the check valve before or after the final carbon block on your drinking water line?

@KStatefan did a good job on showing how it all works...

AirWaterIce, my RO/DI vendor, has an installation document here:

And, swiped shamelessly from that document, their install diagram:

Hope this helps!

The check valve should be before the RO water goes to the pressure tank. The taste and odor carbon filter should be on the line to the dispenser. I have never had an auto shut off valve but here is a picture of my hookup. The check valve is located to the right of the y fitting. The top line goes to the DI system and bottom line to the drinking water tank.

Thank you very much! This helps a lot!
