†If the hardness of your water is above 10 gpg (171 mg/L), limescale 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 to be used with water in excess of 10 gpg (171 mg/L) hardness. ‡A maximum total level of approximately 0.01 ppm sulphide, iron or manganese is permissible. See your local dealer to reduce these substances in your water.
