Problem changing anode rod

I'm 20 months into RV trailer ownership. I have a Rockport Mini Lite. I'm replacing the anode rod. As you can see by the picture I have what I perceive to be a problem. I purchased a Camco 9.5" anode rod. This rod has 11 threads in it. The original rod has 8 threads. Even with this difference the rods are exactly the same length.

Upon inspection there was significant calcium buildup inside the housing for the rod. I deduced that the calcium buildup was the source of my problem. CLR has helped clean most of that up, but as you can see I cannot fully screw in the rod. This can't be normal, right? I have reached full resistance in torquing the rod into the position you see in the picture. Guidance, anyone?

I have never seen one that you fully screw in. The threads are actually tapered pipe threads. Yours looks about correct.


Here is a pic of some anodes. Do you notice the undisturbed teflon tape near the head. This is on threads that did not go into the water heater female. You can tell ow far it was threaded in just by the teflon tape cut by the threads when screwed in.


BTW, did you use any teflon tape or potable water approved pipe dope?

What he ^^said. You should put a wrap or two of teflon tape on the threads.

Also for your viewing pleasure, Suburban sent us a series of instructional videos for their water heaters that we keep at this link:


Suburban Water Heater Video Guides


The first video is on anode rod replacement. You will see in the video the telfon tape marks and how it doesn't screw all the way in starting at 1:17 mark. At the 2:39 mark you can see the installed anode rod is not screwed all the way in, and can see the exposed teflon tape on the still exposed threads.

I don't think you have a problem at all. Like everyone else said make sure you put teflon tape or pipe dope on the threads of the rod before you screw it in. Just snug it up good and you should be all set. Check for leaks after you thread it in and fill the tank by opening a hot water faucet.

Thanks for the responses. Inexperience rears it ugly head. :-)

It's not ugly at all, and in fact is the purpose of these forums...for all of us to learn and gain knowledge from the community collective wisdom/experiences.

You might also want to flush as much calcium out of tank as possible before installing new anode rod.

I'm surprised that you replaced it after only 20 months.
The original one in my Rockwood, lasted over 7 years.
Can you post a pic of the old one?

Here is the anode I replaced.

Yes, I flushed the water heater to remove as much calcium as I could. There was a lot!
