      Note: Recommended hardness not to exceed 10 grains per gallon, or 170ppm. System will operate with hardness over 10 grains but the membrane life may be shortened. Addition of a water softener may lengthen the membrane life.

      The operating pressure in your home should be tested over a 24 hour period to attain the maximum pressure. If it is above 100 psi then a pressure regulator will be required.
