Do not knock that stuff off !!! That is your anode rod. It is normal looking. It is meant to deteriorate through a galvanic exchange process.

If that is the orginal rod in your 2002, then you are doing good. You probably have a couple of more years left on that rod. Wash it off with clear water, put some teflon tape on the threads, and reinstall the rod. It is a good idea to pull the rod out once a year to inspect it.

This is mine after just 2 years of use:

Replace it !

Looks like the anode (zinc) rod is just about had it. It should be replaced.
Looks like about 60% of it is gone. If it were mine, I would replace it. If you continue to use it in the shape it is, your tank will start to break down next.

How old is the anode? If you camp regular during the season or do not drain your hot water tank during the winter, it will speed up the deterioration of the anode.

You can replace it now, if you want to. The replacement rods are about $10 or so at your local RV store. Inexpensive insurance insurance to protect your water heater.

I am planning on letting mine get down to about 25% before I replace that puppy. Having less of the anode does not decrease it's effectiveness. But not having any anode on the rod is not a good thing, so you don't want it to be completely bare.

Some members here replace their rod every year. I am cheap.....if it is still working, that is $10 I will save that year.

Not too sure about that, Sid.

Yes. I don't think the Atwoods use an anode rod.

Bout time to get out the instruction manual to be sure, though.
