I am at a loss why I cant get more product water out. It is cold today though but I have unit in garage.

I was told to use a ball valve to get less waste water and I got it down to 450ML before it was like 900ML..

What is an ideal ratio exactly 4 to 1? My TDS here is extremely high and I heard that a ratio of 4 to 1 is ideal. I also have hard water here.
