anode rod

Well, looks like there is plenty of “stuff” on the rod, but since you’ve already pulled it out, might as well.

You are late! should have checked earlier!
Time to flush the tank.

You still have enough rod left, but like mentioned, the tank could use a good flushing. I think that is why the plug end is used up, but not the extended half. My rod gets down to the wire 1/2 to one inch out, due to the crud accumulating around the drain hole area.

I agree for the cost, I change to a new one, after tank flush. How long did it take to get like the picture?

Why is he late? There is still material on the rod to do the job. As for flushing, I flush every fall at storage time regardless of the condition of the rod.

That reminds me of several parts on my car/RV where..

Well for example the front brake pads. We had the wheels and calipers off for a Different reason so I took one pad to NAPA and the next day they delivered a set of front brake pads.... When we reassemble we put 'em on .. I just became VERY VERY VERY happy we did that by the way (Rears failed).

The rod will deposit debris in tank that can get into system. The rod will decompose faster as the pitted areas allow more area to be exposed.

Cost is minimal for a rod as compared to a rusted out tank.

Flushed a lot of white gunk out. Threads were also coated with white stuff. Used tape when installed and let it sit with WD40 overnight so it was real easy to get out.

This is the OEM 18yo heater.

Am I supposed to replace with aluminum or magnesium?

Different material of anodes are based on water content.
Magnesium works better in most water.

Ok... google says this:

"For harder water an aluminum anode rod is the best choice for your heater and if you live in an area with soft water then a magnesium anode rod is your best choice. Aluminum anodes tend to be cheaper than magnesium anode rods. A magnesium rod will generally last less than an aluminum rod"

Magnesium usually gives better tank protection, aluminum produces less odor.
