Default rusted threads in annode plug socket

The Roadtrek I just purchased had the anode from the hot water heater removed all winter, and there's rust all along the threads where it screws in. Now it only screws in a few turns. Haven't tested it yet to see if it leaks. Any suggestions on how to remove the rest from the threads so I can screw it in all the way? Do you think it's OK to operate this way if the water doesn't leak?

I think you're ok. My annode rod threads always look rusty and it doesn't seem to screw in very far. Since the rust only built up over the winter, it should be mostly surface rust. Just be sure to not cross-thread it as I always find it difficult to start mine properly.

I put thread tape on mine and no leaks. I also put some oil around the outside as that area rusts too.

Clean it up with a small, brass parts cleaning brush. Then carefully thread the anode rod in. I use some Teflon tape and I also noticed the anode does not thread in very far but does seal.

Yeah, ours does the same thing. I clean the threads with a small stainless steel brush (they are still rusty, but smooth), then use teflon tape on the anode rod threads. You should get several turns until tight, but there are still a lot of threads showing -- it does NOT screw in "all the way."

same as other have mentioned...keep in mind that it's awkward to screw in, because the weight is toward the rear. Best to kind of lift it with your deep socket in order to thread it properly.

Last time I installed the anode, I used the a screwdriver in the middle of the socket (to apply pressure to the anode) it made it easier to start the thread, once it was threaded I put the socket on the wrench. It was faster and easier.

Nice tip! I'll try it next time. Thanks!
