Henry Ibsen In case you’re a DIY-type you might well have heard the term water heater anode-and wondered what on earth is it as well as what does it do in a water heater.
Here is a beginner’s guide to water heater anodes, and how to know when it’s time to replace them.
What it Is
Although a water heater anode is a very simple device, it does a lot of work on a daily basis during the cold season. (Just imagine it locked into position somewhere inside the top portion of the home water tank.)
When ever the water-heating switch is turned on, it has to accomplish the process of rising the temperature of the water to boiling point.
Without these, the homeowner will have to make use of an external burner to heat up the bottom of the tank, which is not merely impractical or even time consuming; it is additionally unsafe.
When Something Goes awry
Anode rods are made up of magnesium or even aluminum. With its fundamental construction akin to a walking cane or even sometimes a baseball bat, it is difficult to imagine how it performs its task very rapidly.
After all, no individual in the house has to wait for hot water to be dispensed. If he or she has to, then there is something wrong. A plumber needs to be called quickly, or the lack or absence of hot water can cause a catastrophe especially during the peak of winter.
When to Substitute a water heater anode
Surprisingly, it only takes one rod to heat up a residential tank. Indeed, there is no Plan B, or spare rod. For industrial purposes, tanks normally have two anodes, but neither one of these is a spare.
Both have to carry out the task of heating the water efficiently. Typically, the water heater anode has to be replaced every three to four years, however this time frame could depend on a whole lot of factors just a few of which are the hardness of the water as well as its level of salinity.
Do It Yourself
To achieve best results, it is best to examine the condition of the rod every few years. Extreme corrosion of the metal would mean contacting a trusted plumber instantly.
When one has the time and the handyman capability, however, it should be safe to try to replace the mechanism on one’s own. Just follow the general rules of electricity to avoid electrocution, such as turning the machine off completely or never touching the water.
A water heater anode is extremely cheap, with the most expensive type being in the range of forty US dollars. The homeowner could stress out more about the plumber fee, which can be as high as $300.
Given enough time as well as handyman training, industrious individuals ought to be able to achieve the task without fail.
