1. How tight do folks tighten your anode? (I use Teflon tape on threads and screw it in till finger tight, then little tiny two finger tap on end of socket wrench). 2. When not in use I drain...
I do the same, with these exceptions: I leave the anode out (just place inside at close the vent door). I thought that leaving it out would allow the tank to dry, no home for mold, mildew, etc. to get a start. I may be wrong in my thoughts though! Tightening: We have two units with different tank construction. One has plastic threads where anode rod screws in....I use your described method. One the other, metal threads.....I get a bit more aggressive with the tightening.
