Could your Expensive Hot Water Tank be rusting away?
A Sacrificial Anode in a hot water tank is manufactured from a metal alloy with a greater negative electrochemical potential than the metal it will be used to protect, in this case your hot water tank. The sacrificial anode corrodes instead of your hot water tank, SIMPLE! Magnesium and aluminium are the two types used by the hot water tank manufacturers, plumbonline stock the full range of sizes in "rod" straight and "Flexi" which can be bent for easy replacement where access is an issue. Water heater tanks are notorious for rusting out especially in certain water conditions. Once the tank rusts through, there is only one solution - replacement.
All water heaters leave the manufacturers already fitted with at least one sacrificial anode to protect against rusting. The sole purpose of the anode is to corrode away instead of the tank. Checking the anode at least every 3-5 years or earlier depending on your water quality and replacing if necessary will add to the life of your water heater at a very small cost.
