Pure-Flo II RO/DI Coralife with Pump


Ok, I have this RO/DI unit. It says to keep membrane life longer, you can flush it by switching the red and white hoses. Well, Mine came with Blue and white. Not a big deal, since it's really only color coded BUT, what the heck do I switch? I have connections all over this darn thing. Can anyone help me out here, I want to flush it, but have no idea how. Thanks. :help:
