Clean away particles or any rust using a rag or wire brush in the plug threads. Select matches the hex-head and loosen the plug using a wrench. Lift the plug and connected anode rod from the hole in the tank. Raise it up as far as feasible for evaluation when there’s insufficient clearance to totally eliminate the rod.
Examine the rod for indications that it is born for substitute, including a big amount of steel that is lacking, or if 6″ or mo-Re of core wire appears a-T either end-of the rod. If alternative is needed a magnesium anode rod.
Wrap the threads of the rod that is anode plug with three turns of plumber’s sealing tape. Lower the rod to the tank. Thread the plug and tighten it using a socket wrench.
