feeding membrane with waste water

[Daftoldgit]

The ppm did rise a little.. After tweaking it I found the sweet spot for me was a ratio of 2.2 - 1
I'm getting 4ppm on that ratio. Anything above that the ppm rises.
Thanks for the suggestions on this!

It takes a while for the membranes to 'react' to waste adjustment tweaks. As you start your r/o you will find the tds of your pure is high but will quickly drop as the r/o gets going. It's called 'tds creep.' My r/o does the same. The last point drop on my pure (from 4ppm to 3ppm) can take up to 15 minutes.
