Once out replace it with the usual plastic (pvc?) plug with teflon tape on the threads. The Heater tank should be flushed out at least once per year which requires the removal of the plug and use of a `wand' to be effective.
I agree with only using plastic replacement plug. Also make SURE That you do not overtighten the plug.
I turn mine in hand tight, with two layers of teflon tape, and then snug it with a wrench only about 1/2 turn. This makes it easy to remove. If it drips, then tighten another 1/2 turn just until it stops. Remember you are only trying to hold back 40 PSI, and should be using a pressure regulator on the RV plumbing system.
