Water Heater Anode?
Pulled the water heater drain plug on our new to us this fall camper. We have an Attwood water heater and to my surprise out came an anode on the drain plug. It has some rust on it and looks like it...

Per the Atwood manual:
ATWOOD CLAD TANK
The Atwood water heater tank is constructed of a core of high strength aluminum. The interior of the tank consists of a 15% thickness of type 7072 aluminum (pure aluminum and zinc) that is fused to the core during the rolling process.
This material protects the tank from the affects of heavy metals and salts found in waters throughout the country. It is anodic to these heavy metals and acts much like an anode in a steel glass lined tank except it will last much longer.
There is also no need to replace an anode on a yearly basis.
Flushing the tank on a regular basis has been found to be helpful in insuring the best performance of your water hater and adding to the useful life of the tank. For flushing instructions see your owners manual or contact Atwood for a copy of our recommended procedures.
