N80:
they said removal of the hot water anode rod was beause the anode that comes standard in hot water heaters are made of a material that basically rusts away it does so to prevent the water heater from RUSTING through. BUT they make a great home for bactiria to land & surive/eat on... SO if you have some high iron water then this rod gets slimey with bacteria which causes a rotten egg smell in the hot water. to fix this you change the material that the anode rod is made of. this means that for high iron water this is a al/magniezium type rod (cant rember which rod for which type of water.!??? ) anyhow there I belive several different types of hot water heater anode rods. you NEED one type for high iron content water. you need a different type for water without the iron...
you HAVE to have it in there to prevent the bacteria from eating on the pipes & hot water heater. they are there and shocking the well will kill them off for a short time and they will be back. remember drinking water shocked with bleach can be very harmfull, also using pool tabs is dangerous and can't be used to drink for a long time as that stuff can cause serius health hazzards.
anyhow take a water sample to a good plumbing supply and get the right anode rod for you're water and you will be set..
