hot water heater question.
Re: removal and especially reinsertion of the hot water plug is very difficult due to a long apparatus connected to the insertion nut. Is there any way to limit calcification of the nut to make it ...

Anode rod used in Suburban Water heaters are there to protect the glass-lined steel tank from corrosion.
The anode rod is made up of drain plug with steel center rod and either aluminum or magnesium sacrificial material.
Aluminum ones will last longer BUT can collect deposits (calcium etc.) which can make removal of rod difficult.
Magnesium ones deteriorate faster BUT can interact with bacteria in some water supplies and cause a sulfur smell.
Routine draining/flushing of water heater helps remove build up in tank.
After removing drain plug, flush tank thru drain hole. You can purchase a 'wand' for this at most any RV Supply.
Clean up threads.......you can use a small wire brush (auto parts store) OR the best thing is to purchase a 3/4" NPT tap and run it thru threads.
Then use a small dab of 'never seize' on drain plug threads and reinsert into tank. This will help keep threads from corroding and make it easier to remove next time.
Replace anode rod when it has deteriorated 75%
