Remove the anode rod and trash it.
Open all low point and tank drains, then cap them off or close the valves.
Flush the hot water tank with a wand, use a regular steel plug to pug the tank and then flush the whole system with 1/4 cup of bleach per 15 gallons of water.
Using the water pump run water thru every line even the low point and tank drain, do the outside shower if you have one.
Do that as well.
Drain and flush the system until you no longer can smell the bleach.
Replace the steel plug with a new anode.
