Rusted anode nut

Hi!!

I recently purchased a 2008 Keystone Springdale 249 fifth wheel from an older couple, who only used it one month out of the year. They stored it inside otherwise. :B However, I'm not sure how much regular maintenance was done. :?

It has a Suburban water heater. The anode nut has a lot of rust on the threads where it goes into the water heater. I have a 1-1/16" socket, but can't break the anode rod loose, even with help from a hammer. I've tried a little WD-40 on the threads - no good. The seller said the water heater worked fine. I figure if it's rusted really bad there, the rod itself is probably shot.

Any suggestions?

Thanks!!
  • Thanks! I just tried my Lithium battery powered impact wrench. No good. I'll look around for a pipe, to get more leverage.
  • WD-40 is USELESS for freeing rusted objects.
    The best product is PB Blaster. Squirt liberally for 2 - 3 days before trying to break nut loose.
  • A six point socket, a short extension, and a power bar with a pipe on it. Have a helper bang with a hammer onto the power bar extension as you apply pressure at the end of the pipe. I expect it will come loose then.

    Or an electric or air powered impact gun.
