TOTAL DISSOLVED SOLIDS
The stainless steel cylinder of the water heater is not covered by the Rheem
warranty when the total dissolved solids (TDS) content in the water is greater
than 600 mg / L.
Note:
Some water analysis reports may state the conductivity of the water rather
than the level of total dissolved solids. Conductivity, measured in microsiemens
per centimetre (
µ
S / cm), is directly proportional to the TDS content of the water.
TDS, in mg / L, is approximately 70% of the conductivity in
µ
S / cm.
SUMMARY OF WATER CHEMISTRY ADVICE AFFECTING WARRANTY
The water heater and its components are not suitable for certain water
chemistries. Those chemistries are listed below. If the water heater is connected
at any time to a water supply with the following water chemistry, the Rheem
warranty will not cover any resultant faults on the components listed below:
