MAJOR SERVICE EVERY FIVE YEARS
It is recommended a major service be conducted on the water heater every five (5) years. If an anode
replacement is conducted sooner than a major service, then the major service should coincide with the

or their nearest Accredited Service Agent.
Note: The major service and routine replacement of any components, such as the anode and relief valves,
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 required, replace the valve.

Inspect and if required, replace the anode.
If the anode is not replaced, it should be replaced within three (3) years of this service (refer to
