Anode Rod inspection
Property Damage Hazard
, Avoid water heater damage.
• Inspection and replacement of anode as needed.
The anode rod is used to protect the tank from corrosion. Most
hot water tanks are equipped with an anode rod. The
submerged rod sacrifices itself to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod. This does not affect the water's taste or color. The rod must be maintained to keep the tank in operating condition.
Anode deterioration depends on the water conductivity, not
necessarily water condition. A corroded or pitted anode rod
indicates high water conductivity and should be checked and/ or replaced more often than an anode rod that appears to be
intact. Replacement of a depleted anode rod can extend the
life of your water heaten Inspection should be conducted by calling Sears Service Center. At a minimum the anode(s) should be checked annually after the warranty period.
