Thanks Randy, and I’ll certainly get the anode from you if I can get these nipples out. I’ve tried a couple of times with a pipe wrench, but they’re not budging. So far, they haven’t collapsed – they’re still fairly solid. I’ve put penetrating oil at the base of the threads and giving it time to soak in. I also hope they weren’t sweated-in at the factory. I just recently replaced the thermostat assembly.
