Rapid decay of magnesium anode

AQUA PLUS indirect-fired water heaters — Product Manual

Troubleshooting (continued)

1 Anodes last less than two years

The purpose of the magnesium anode is to reduce the damaging effects of aggressive water on the water heater. Aggressive water will cause the anode to erode.

The anode must be inspected at least annually to determine whether a new anode should be installed.

Severe or rapid deterioration of the anode indicates very aggressive water. If this occurs, have the water tested to verify whether it is within the limits given under “Operating restrictions,” page 3.

Failure to inspect the anode regularly and replace if necessary could result in damage to the water heater, causing possible severe personal injury, death or substantial property damage.
