I am looking into replacing anode rod on my water heater. One of the biggest emphasis during this procedure is ensuring that after replacement anode rod remains in contact with tank - threads when rod is screwed in should remain in contact... this ensures conductivity so that anode rod can do it's job.
However, I can't find which pipe dope I should use for this job. I've called Rheem (water heater manufacturer) and they recommend just wrapping teflon tape - hoping that tape will break when I screw anode rod in. Since teflon could isolate rod and break conductivity I would prefer to use some conductive pipe dope instead (this is what professional plumber suggested).
Unfortunately I can't seem to find pipe dope that's conductive. I've spoke to few employees in local Home Depot and they have no idea if certain pipe dopes are conductive or not. So, can you recommend a brand of pipe dope that is used for jobs like this?
