WATER SUPPLIES
Water heaters must be installed in accordance with this advice to be covered by the warranty.
A Rheem water heater is manufactured to suit the water conditions of most public reticulated water supplies.
However, there are some known water supplies which can have detrimental effects on the water heater and
its operation and/or life expectancy. If you are unsure of your water chemistry, you may be able to obtain
information from your local water supply authority. This water heater should only be connected to a water
supply which complies with these guidelines for the water heater warranty to apply.
ANODE
The vitreous enamel lined mild steel cylinder of the water heater is covered by warranty where the total
dissolved solids (TDS) content in the water is less than 2500 mg/L and when the correct colour coded anode
is used. The use of an incorrect colour coded anode will void the cylinder warranty and may shorten the life
of the water heater cylinder.
The correct colour coded anode should be selected and fitted to the water heater in accordance with the
following advice and the “Water Chemistry Charts” for TDS on page 11.
Total Dissolved Solids
Anode colour code
0 – 40 mg/L
Green
40 – 150 mg/L
Green or Black
150 – 400 mg/L
Black
400 – 600 mg/L
Black or Blue
600 – 2500 mg/L
Blue
2500 mg/L +
Blue (no cylinder warranty)
The changing of anodes must be carried out by a plumber or authorised service person.
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 (µS / cm), is directly proportional to
the TDS content of the water. TDS, in mg / L, is approximately 70% of the conductivity in µS / cm.
ANODE INSPECTION
The anode(s) installed in a vitreous enamel lined mild steel water heater cylinder will slowly dissipate whilst
protecting the cylinder. The life of the cylinder may be extended by arranging for an authorised person to
inspect the anode(s) and replace if required.
The suggested maximum time after installation when the anode(s) should be inspected in the heat pump is 8
years.
For water supplies which are either softened, desalinated, of poor chemistry or where the water supply may
alternate between rainwater tank and a reticulated public supply or another supply, it is recommended the
anode(s) be inspected 3 years earlier than shown (refer to “Anode” on page 9).
It is recommended the anode be inspected during a five year service of the water heater, if one is conducted.
