I started to just post a question at this thread:
Removing anode rod to drain hot water heater.
But decided maybe rules say I should start a new thread so as not to hijack, so here goes:
Reading these last posts in that thread has me feeling a little worried.
Out of ignorance, when I did my usual winterizing my 2002 ( bought used a few years ago) FR Flagstaff DS 26 UL last November, I left the anode out after draining the water heater. ( I'll have to pull the paper work out to find the brand of water heater, I don't see it written on the heater)
I probably did that on purpose, for whatever reason, being ignorant and all! Or maybe I just forgot to put it back in. Due to various reasons, we did not get to go camping this summer. So now that the cooler weather is getting here, we decided it is time to go before winter gets here again. So I go to replace the anode and I discover that the threads on the heater are major rusted. Enough that it seems to be interfering with getting the anode threaded back in, not that that was ever easy for me any way.
So now I need some tips on getting rid of that rust, at least enough to get the anode started. Hopefully there is a way to do it, or else it is time for a repair bill. Any suggestions?
And I'm thinking if I buy a 1 1/16 socket, it will make it easier to thread this thing, because maybe I can hold it straighter? As it is, trying to thread it by hand(even before the rust problem), the end of the anode, inside the water tank, tends to pull it down making it real hard to get threads lined up. You guys think that using a socket/ratchet idea will help any keeping things straight?
But even if I get the rust removed from the threads, after reading the above threads I'm afraid there might also now be major rust inside the water tank. Since it was stored last winter and this summer with that heater anode hole unplugged. Any way to test for this? some sort of tank flush maybe?
Thanks in advance for any thoughts/ideas!
