+
+Flow of water:
+1. Filter 1
+2. Filter 2
+3. Filter 3
+4. Low pressure switch
+5. Solenoid
+6. Input for TDS Adjuster
+7. Membrane -> Flow restrictor on the drain
+8. Merge back TDS Adjuster
+9. T-Connector which goes to the Pressure Tank
+10. High pressure switch to turn off the RO When the tank is full.
+11. Post Carbon Filter
+12. UV Filter
+13. Output at 30-40 PSI as set in the Pressure Tank
+
+
+
+150 GPD Membrane (AXEON Maybe) Check initial TDS

+1600 mlm flow restrictor (restrictor mlm * .38 / 4 = Membrane GPD)
+Check A Solenoid valve before the membrane
+150 GPD pump
+Check all the filters
+UV Filter
+TDS Adjuster to control the TDS (Input from before the membrane and output to after the membrane but before the uv filter)

+Pressure tank after (35L should be fine)

+
+line after uv tank T to ro and outlet and a high pressure switch there to turn off the ro when the pressure is high. then a T ... one to the ice machine and other to the water tank
+
+this will take care of the RO for both
+
+Pressure should be 60 + .... but with the pump, that should not be an issue
