Gotta little ro system to help with my pure water. It has a little di on it. It also has a tap for waste water which I will save for my trading. My question is when I am filling up my backpack/25 litre drum it will go through my ro & then through my 4.5 litre di. Do I have the waste tap open while filling up these or do you let it out at the end.
