|A bunch of hot water geyser anode rods|
Sometimes I find that the most mundane of objects have the most critical purpose as well as a very evocative name; one such is the emotionally titled - Sacrificial Anode Rod. To the uninitiated, this object performs a vital function for your hot water geyser, amongst other things -
A sacrificial anode is one of those little things that mean a lot. They keep steel boats, marine engines, water heaters, bridge pilings and many other wet metal objects from rusting into dust prematurely. Because, by using an anode made of a metal like zinc, the anode will decompose before the steel will rust, so the steel is protected. (Website: Howstuffworks )
In other words, this noble piece of metal gives up its life for the benefit of its host and if you want your geyser to live long - you must find its Sacrifical Anode and change it every two years. I have taken note as we have had no less that FOUR new geysers in the last 20 years in the same house. Doubtless our Sacrificial Anode had never been changed, judging by the blank look on my husband's face.
