    Question Water heater anode rod replacement

    When replacing a water heater replacement rod, I understand you should wrap the threads with teflon tape as a leak preventative and also to make it easier to remove the next time, but doesn't the tape insulate the threads from the tank and prevent conductivity between the rod and tank? Should a small section of the threads be left untaped to make conductivity or does the tightening of the threads compress and tear the tape enough to make conductivity at a few points?

    the teflon tape is fine and will have no effect on the anode rod at all. there's no electricity running through the rod.

    Not going to effect it at all the electrolisis is inside the tank in the water not the rod itself.
