It is common knowledge that rust spells the death of most metals. Created by exposure to oxygen and/or water, rust eats away at metal objects. The question you may have is how your water heater doesn’t succumb to this issue since it literally holds gallons of water all day, every day.
The answer can be found in the anode rod. This is a part of standard storage water heaters in Santa Ana and beyond. This seemingly simple part of your water heater allows your system to function for multiple years without corrosion eating at it from the inside-out.
What Is an Anode Rod?
If you were to look inside your water heater tank, you’d see a long metal rod sitting in the center of it. This is the anode rod. Usually made from magnesium, aluminum, or aluminum/zinc alloy, the anode rod is a part of your system that “sacrifices itself” for the sake of your water heater’s overall lifespan.
How an Anode Rod Protects Your Water Heater
The anode rod is made to attract the sediments and minerals that would otherwise eat away at the tank of your water heater. Instead of attacking the tank, these compounds go after the anode rod and break it down—and that is okay because it can be replaced regularly. This helps to maximize the longevity of your water heater. The anode rod is highly important to keep your water heater usable rather than allowing it to fall prey to corrosion in a short amount of time.
Be Aware: Your Water Heater May Still Develop Rust
You might think that an anode rod is going to be all you need to keep your water heater in good shape. While your anode rod does play a highly vital role in your water heater, it won’t keep it rust-free forever. You need to replace your anode rod regularly to keep your water heater running right. Along with this, you should also have your system regularly maintained and, if necessary, flushed, to get rid of sediment build-up that might affect effectiveness and efficiency.
It is important to understand though that the older your system gets, the more likely it will be to develop rust and corrosion, even with regular anode rod replacements. If your water heater develops corrosion and rust within the tank itself, it will mean you need to replace the system for a while. However, with regular anode rod changes and maintenance, this shouldn’t happen for a good long while.
