hi gmann,
My RO dealer suggested a use of a booster pump to extend the life of the membrane. A cheaper alternative is a permeate pump that you can get from water supply stores.
"Permeate Pump is a non-electrical device which is powered only by the hydraulic energy of brine water. The Permeate Pump forces product water into the storage tank, reducing membrane back pressure while maximizing available feed pressure. This pump drastically improves the efficiency of Reverse Osmosis systems and can reduce waste water up to 80%."
