The way I have build this unit is in the water saver way. The waste water from the first membrane is feeding the second. Both menbrane I am running the 150 gpd flow resrictors. The booster pump is ratted for 100psi. I have a pressure guage on the first menbrane it is at 98-100psi and the second membrane has a guage to it is at 45psi. I have tested it it produces 12.5gph of pure water and my tds meter reads 0. I am really happy way it preforms. Better then that POS Coralife pure flow 2 50gpd when it wants too.
