The threads where the anode rod goes on my Suburban water heater aren't all neat and pretty. When I try to screw in a new Suburban anode rod it only goes in half way. Is this normal? If not, is there something I can use (toothbrush alone did not work) to clean up the threads so the anode rod will go in further?
The threads are pipe thread which are tapered. They are designed not to go all the way in.
The anode needs to contact the metal of the tank. Go easy on the Teflon tape or use pipe dope.
