Maybe I'm interpreting it wrong?

Out of curiosity, do you still work for Proline (Vertex's distributor)? If so maybe you know the answer to this. I understand that some units use some of the DI water it creates to backflow the membrane and some (probably most) just use pure tap water through the membrane. What method does the Vertex unit use for flushing?

I don't work for them anymore (over six months).

Ignore what the site says. It enables increases in PSI, but is mainly there to improve the water/waste water ratio.

I'm not sure what function is used for the backflush, unfortunately.
