Extend The Life Of Your Water Heater With A Replacement Anode Rod

Generally, replacing your anode rod at regular intervals is bound to increase the overall life span of your water heater, saving you time, money and the inconvenience of having to replace your water heater. To extend the lifespan of your water heater, it is important to ensure that the anode role is performing its main role; that of diverting corrosive action away from the tank walls to the rod. Depending on the overall needs of a homeowner, there are several options which one can choose from; these include Tin, a combination of aluminum and Zinc, Magnesium and Aluminum which are by the far the most common. It is also worth mentioning that there are flexible options for difficult access points and low ceiling clearance.

The overall condition of the anode rod and whether it is time to replace it or not is usually dependent on a wide array of factors such as the quality of water, how frequently one uses the water heater, the overall running temperature as well as the craftsmanship of the heater in question. In addition, it is important to note that water softened using sodium normally gives the anode a much shorter lifespan. It is highly recommended that you replace the anode rods if your water heater is at least five years old or when your water heater constantly makes multiple or loud popping noises when heating up or when you notice that your faucet aerators are clogging more frequently. Another tell-tale sign that your rods needs replacement is the presence of rotten egg odor in your water or the presence of some slimy substance in the faucet aerator.

Aluminum rods are usually the least expensive and create the lowest voltage during the sacrificial process. This does imply that they tend to corrode at a much slower rate than most anode rods in the market. it is also important to note that anode rods that have a thickness of � inches are bound to last longer than rods which have a thickness of 5/8 thickness if conditions are maintained at a constant.

Magnesium rods are also quite popular. They are generally used to protect the inside metal surface of the water heater tank with the magnesium corroding instead of your water heater. However, magnesium rods tend to create a high voltage during the sacrificial process which corrodes the rod much faster than other rods.

For those who are keen on removing any foul odor in their water, then the Aluminum/Zinc/Tin anode combination is usually used. This happens because zinc is a natural anti-fungal element and can help in controlling the growth or iron bacteria which normally causes that annoying rotten egg smell. It is worth mentioning that zinc oxides and zinc compounds are usually indigestible to a wide array of micro-organisms such as bacteria.

Flexible aluminum anode rods are specifically designed for limited spaces where it is almost impossible to insert a straight anode rod. This normally includes spots such as closets, low ceilings, under stairwells, attics or in basements.
