How an Anode Rod Protects Your Water Heater
Water heaters share at least one important trait with all other mechanical objects and systems: they don’t last forever.
Storage tank water heaters have an average shelf life of 10-12 years. But unless someone keeps an eye on your system’s “hidden ingredient”, it can fail well before it’s time.
We’re talking about the sacrificial anode rod that all electric and gas storage tank water heaters come equipped with.
How did sacrificial anode rods get their name? Easy: their purpose is to sacrifice themselves to spare the inner lining of your water heater’s storage tank. Without them, rust and mineral corrosion can eat away at the storage tank’s internal lining, thus causing it fail.
Anode rods, made from magnesium itself, succumb to those same corrosive substance before they can attack the inside of your tank. And since an anode rod is likely to fail before your water heater, it needs to be periodically checked and replaced as needed.
How to Protect Your Water Heater and Anode Rod
At Arnold & Sons Plumbing, we recommend annual water heater performance and safety inspections. These include the anode rod along with all other system components. On the safety side, we also check for potential carbon monoxide and gas leaks.
