Hot Water Heater Anode…can you recondition it?
I have two water heaters in series. The original conventional heater was left in line when a new ‘high efficiency’ tank put in. (It was cheaper to leave it, and water comes up to room temp before it goes into the new heater.) I wanted to replace the anode in the old tank as it started to leak around the fitting. Figured it was wasting away to nothing. Bought a ‘bendable’ rod because its in a tight space and planned to cut the old rod if there was anything left. When I pulled the old out as far as I could get it (about 18″), the rod is solid. The surface was coated and almost looked like copper, but if I scape it you can get down to the metal beneath it (I think aluminum). So thats what I did, retaped the threads, and put it back in the tank. No leaks, but do I need to replace the anode or will the 18″ of scaped surface suffice?
BTW changing the rod in the new tank will be significantly more difficult, same tight space but also have to remove blower and ducting to get to anode…great design work! I figure I can wait a few years, especially if the first tank anode is still working(?)
