Page 14: Water Quality
WATER QUALITY Water quality from an RO system is normally determined with a TDS Meter, which measures total dissolved solids in water, measuring conductivity. The results are normally measured in parts per million or milligrams per liter. Fewer dissolved solids results in higher quality water. RO membranes are rated by the amount of dissolved solids they reject, expressed as “rejection percentage”. -
Page 15: Fittings
PUROMAX BRAND FITTINGS Many RO systems utilize PuROMax brand fittings. These user-friendly fittings provide superior performance and may be provided with this system. Proper use of these push-in fittings is shown below. Along with these fittings, all tubing selected must be of high quality and must be cut with a plastic tube cutter or sharp razor with a clean, square cut. -
