Does Your RV's Water Heater Need An Anode Rod
I have a 2002 Fleetwood Mallard with a 6 gal water heater tank. The area where the Anode rod is inserted is plastic, with a plastic plug, and I was told this type setup doesn't use the Anode rod.
Being new to camping, I'm not sure what to think as I was told all tanks need the rod to avoid corrosion.
Is there any way for me to check?
ANSWER: Hi, the simple answer to your question is that if your RV's water heater is an Atwood than it does not require an Anode Rod
I am pretty sure that your Mallard is equipped with an Atwood Water Heater, but you should still take a look at your water heater and see if Atwood or Suburban manufactures it. The fact that your water heater is equipped with a plastic (nylon) drain plug pretty much indicates that it is an Atwood.
If you do have to replace the Anode Rod in your Water Heater; you will find that it is a simple and straightforward job, but you still may want to take a look at the video below to see how it is done.

As the video states when you are replacing the Anode Rod it is also a good time to flush your RV's Water Heater
to get rid of any Sediment etc.A Suburban Water Heater requires an Anode Rod because the tank of the Suburban Water Heater uses glass enamel over a steel tank. If the enamel cracks for any reason, it will expose the steel to the water, and the steel will start to corrode even from a pinhole in the enamel. The rod attracts the corrosive elements in the water that could corrode the water heater tank, and the rod itself gets corroded.
The Anode Rod is part of the Suburban Water Heater's drain plug. It should be checked at least once a year and should be replaced when half of the rod has been corroded away.
So why doesn't the Atwood need an Anode Rod? The water tank on the Atwood Water Heater is made of aluminum which does not have the same corrosive properties as steel
I hope that this information has been helpful to you.
