sacrificial anode replacement by Whywait PlumbingMost of us know we have a hot water service. We turn on the hot water tap in the shower or sink and in a short time we have hot water.

Unless we have no hot water we take very little notice of the hot water t, nk. That is of course until the tank leaks and it needs replacing. On average hot water tanks have a life expectancy of 7 to 10 years but did you know that life expectancy can be doubled very easily by some simple maintenance such as flushing the system and undertaking a sacrificial anode replacement.

Every type of hot water storage tank that is manufactured from steel with a vitreous enamel lining comes complete with a sacrificial anode installed. These tanks are electric, gas, solar and heat pump hot water storage systems manufactured by Rheem, Dux, Vulcan, Quantum, Solahart, Aquamax, Everhot, Rinnai, Radiant, Stiebel Eltron, Saxon, Beasley, Conergy plus many other tanks that are privately labelled.

What Is A Sacrificial Anode?

The Sacrificial Anode installed in your HWS tends to have a life expectancy equal to the sacrifical anode replacementwarranty period of your hot water storage tank. The photo on the right illustrates perfectly the difference between an anode that has been in use for 4 years on the bottom and a brand new anode on top.

A sacrificial anode is manufactured from magnesium and is used in a hot water storage tank because when two dissimilar metals are connected and are both in contact via an electrolytic solution, a weak electric current is formed. This weak current produces a cathodic/anodic reaction between the two metals. Therefore, one metal will corrode in order to protect the second metal which is why the magnesium sacrificial anode corrodes. The atoms of the less stable metal form a protective coating over the more stable metal. This is why the steel tank will not corrode while the magnesium sacrificial anode is intact.

Essentially the two dissimilar metals are the anode and the mild steel hot water tank. These two metals are connected at the anode fitting at the top of the hot water tank. The electrolytic solution is the potable water in the hot water tank. The vitreous enamel lining separates the water from the mild steel hot water tank, preventing the electrolytic circuit from being complete.

However, if any small areas of steel become exposed, protection is given by the sacrificial anode. The anode provides protection by forming a protective coating over the exposed areas of mild steel, extending the life of the hot water tank.

The rate of protection depends on water quality, the level of total dissolved solids (TDS) and water temperature. The most suitable type of anode material is determined by the water quality and in South East Queensland that is magnesium.
