I was wondering if anyone could explain to me what the anode is for on
my water heater.  I've also heard it referred to as a "sacrificial
anode" which leads me to believe it might be something that needs to be
replaced once in a while.  My water heater is about five years old and
there's quite a bit of what appears to be some type of corrosion around
the anode on the top of the unit.  I just bought the house a year ago
and there was no documentation for the water heater, so I'm hoping
someone here can tell me what a good homeowner should know.
