Thanks.
It's false. I use Teflon tape and measured zero ohms resistance from the plug to the heaters chassis (no water in tank). It was the same with the pipe dope I used on my brothers trailer.
CORRECT ANSWER. Teflon tape (certainly 2-2.5 wraps) does NOT electrically isolate pipe threads and IS a good idea.
Even though the tape is "between" the threads you still get metal to metal contact. The purpose of the tape is to be crushed between the threads to fill gaps and imperfections in the threads to stop water from leaking down the spiral of the thread. It is the same with pipe dope.

Thanks for all the input. I have decided, after reading the replies, to talk to my RV repair Guru at The RV Camper Clinic before attempting something that could possibly damage the tank.
Thanks again,

Mainetom has the right idea. There is a chisel made for that purpose. It is slightly rounded on one side to fit the contour of the hole. We called them round nose chisels. They come in different sizes for different size pipe. You will need about the smallest one made. Set the chisel against the male thread and angle it ever so slightly toward the center of the broken piece and tap hard with a hammer. Hopefully you can fold it inward. Then it should be loose and will come out easy. Care should be taken not damage the female threads. You may need a pipe tap to clean the female threads anyway.

My RV Guru looked at the threaded plug that broke off and told me that it was the complete metal plug and the magnesium anode had swollen & jammed in the hole causing it to separate from the metal plug and remain in the outlet hole even more jammed. I was advised to just tap in back into the tank an leave it on the bottom to further disintegrate, put in a new rod and remove the old one when it has disintegrated to a point where it can be fished out. So, I guess for a while, the tank will be double protected.
Thanks again for all you replies and hope my explanation was understandable,
Radar.
