hot water heater plug and rod

Went on our first trip and had a blast everything seemed to work at last. Today I drained the hot water tank and removed the the plug and found a rod connected to it. To most RVer's that would not be a suprise but to me it was. This is our first RV and do not remember anyone telling us anything about that, we even bought Mark Polk's DVD on class a's and all he did was removed a plug to drain his tank and no rod. If this question seems dumb to you, then I am dumb but I am asking it. We have a 2012 Georgetown 350F,V10,5speed and have a 10 gallon water heater tank. I thank you in advance for all your help

You have to replace the plug with the rod(anode) every couple of years. They are for corrosion.

Bojack - just to add a little here, your home hot water heater will also have an anode rod installed. On the home HWH I have worked on, the anode rod is screwed in from the top and goes from top to botton while your RV HWH anode rod is screwed in from the bottom and goes across the bottom of the tank.

You can go on the Camping World site and do a search and you will see what they look - not very expensive.

As a strong suggestion, when you put it back in, make sure to use teflon tape, as you will read from other posts they have a habit of seizing if left for any lenght of time without taped threads.

excellent point
our unit is only a few years old
and when I removed this a while back
it was everything I could do
just to get it out

I repaired pipes for prox 15 years
but
still even with the right tools
(one which bent -- hard strain to remove)

when put back in
I used even a little extra teflon tape
I may be the poor guy
who has to take it out next time

seriously
thought something was going to break while removing !

The anode rod serves a very useful purpose. Instead of your water heater corroding, the anode rod will deteriorate due to galvanic exchange. Depending on the impurities and metals in the water, an anode rod can last for many years. Here is mine after 3 years.

That puppy is only about 90% used up, and has many more years to go.

If it looks like this, then you have waited way to long to replace it:

Are the replacement rods all the same? I have not ever purchased one.

I am not sure - just take your old out and measure it before buying a new one.

Yes, I have done that and had it posed next to a tape measure to assure that the length will be correct, when the time comes to replace it.
