* Flow rate depends on variable factors such as feed water pressure, feed water characteristics and condition of the membranes and filters. 
** Recovery and TDS reduction percentages also depend on variable factors such as life and condition of the membranes and filters, feed water pressure, feed water characteristics. 
*** If input pressure exceeds 30 psi, a pressure reducing valve needs to be installed at the feed line. If the pressure is lower than 7 psi, a booster pump needs to be installed.
