    A list of postcodes is available on the Rheem website (www.rheem.com.au) indicating known areas where the stainless steel cylinder is not covered by the Rheem warranty due to the water chemistry of the area. The list is not necessarily exhaustive and there may be areas outside of these postcodes where the stainless steel cylinder is not covered by the Rheem warranty due to the water chemistry of the area.
  • Page 16 Where the pH is less than 6.0 or greater than 9.5, the Rheem warranty does not apply to a stainless steel cylinder. Water with a pH less than 6.0 may be treated to raise the pH.
  • Page 17 Where the saturation index exceeds +0.40, the water is very scaling. An expansion control valve must be fitted on the cold water line after the non- return valve to protect and for the Rheem warranty to apply to the temperature pressure relief valve and water heater cylinder.
  • Page 18 WATER SUPPLIES TOTAL DISSOLVED SOLIDS The stainless steel cylinder of the water heater is only covered by the Rheem warranty when the total dissolved solids (TDS) content in the water is less than 600 mg / L. Note: Some water analysis reports may state the conductivity of the water rather than the level of total dissolved solids.
