Flow rate and output are determined by 3 factors:
1
Incoming water temperature
2
Total dissolved solids (TDS) present in supply water
3
Incoming water pressure
Lower temperatures are directly proportional to slower flow rate. All membranes are tested
at 77°F. Incoming water temperature should not exceed 100°F. The RO Filter System
should also not be installed in a location susceptible to freezing. The more TDS in the
supply water, greater filter time is required. Incoming TDS should not exceed 1000 ppm.
Higher water pressure enables a higher flow rate. Pressure must be above 40 psi for
proper system operation. You may consider installing a permeate pump or booster pump
if your pressure is below 40 psi.
Drain Flow Restrictor
The restrictor is vital for proper operation of the RO membrane cartridge as it keeps water
flowing through the membrane at the proper rate ensuring the water produced is the best
quality. It is recommended the restrictor assembly be periodically inspected to be sure it is
clean and unrestricted. If service is required on the drain flow assembly, disassemble and
reassemble as outlined in Step Six.
*Filter life depends on water usage and water supply quality.
