  • Maximum Hardness: 10 gpg (171 mg/l) If the hardness of your water is above 10 gpg (171mg/L), lime scale will build up rapidly on the membrane. Scale buildup will plug the membrane and make the system ineffective.
  • We do not recommend these reverse osmosis systems be used with water in excess of 10 gpg (171 mg/L) hardness, unless the water is softened prior to the reverse osmosis system.
  • Chlorine In Water Supply: less than 2 ppm
