The stream off water going to waste looks as though I have still got my 300god ro running if you understand what I mean . Does that sound right I just want to make sure I have set it up right cheers Kev
How do you regulate the waste/product ratio?
To check it: have 2 containers handy, one at least 4 times as big as the other. Run the product into the smaller container and the waste into the larger. Stop the RO exactly at the point the smaller container is full.
Discard the water from the smaller container.
Pour the water from the larger into the smaller, take note of how many times you can fill the smaller. This will give you the waste/product ratio. Opinions differ as to the best ratio, some say it should be 1:1, I prefer to run at 2:1, not having enough waste can shorten the life of your membrane because there's not enough water 'washing' the filtered dissolved solids from the membrane.
