The Vertex website seem to indicate that the pumps is used to boost low source water pressure. Here is the quote directly from Vertex's website.

"Each Deluxe Puratek RO/DI system is furnished with a Vertex™ HP-100 Booster Pump, enabling the setup to operate at the lowest source water pressures."

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?
