MAINTENANCE REQUIREMENTS
MAJOR SERVICE EVERY FIVE YEARS
Warning: Servicing of a water heater must only be carried out by qualified
personnel. Phone Rheem Service or their nearest Accredited Service Agent.
Note: The five (5) year service and routine replacement of any components, such
as the anode and relief valve(s), are not included in the Rheem warranty. A
charge will be made for this work. Only genuine replacement parts should be
used on this water heater.
The major service includes the following actions:
Replace the temperature pressure relief valve.
Inspect and flush the expansion control valve (if fitted). If required, replace
the valve.
In areas with water supplies that are either softened or desalinated, or where
the water supply may alternate or is variable: inspect and (if there is any sign
of depletion) replace the anode. Refer to “Anode Inspection and
Replacement” on page 14.
Check the electric heating unit for excessive calcium build up or corrosion
and replace if necessary.
Visually check the unit for any potential problems.
Inspect all connections.
Check the drain line from the safe tray (if one is installed) is not blocked.
Note: The water heater may need to be drained during this service. After the
completion of the service, the water heater will take some time to reheat the
water. Depending upon the power supply connection, hot water may not be
available until the next day.
