What is a Water Heater Anode Rod
An anode rod is a lengthy metal rod that is typically comprised of magnesium or aluminum around a steel wire core. The rod lies on the inside of the water heater tank. It is developed to slowly break down over time. Once the anode rod is consumed, the tank will not be protected to corrosion. Why is that?
Thanks to the procedure of electrolysis, the metals of the anode rod bring in ions that would certainly trigger corrosion in iron and steel. These ions are exactly what gradually deteriorate the anode rod, but that is exactly what it is designed to do. When the anode rods are consumed, they need to be changed. Which is why it is necessary to examine them yearly to aid get the lengthiest life possible out of ones hot water heater.
Checking the Anode Rod
The anode rod will get to the point where it can not attract ions any longer. This is the time for a replacement anode rod. Without them, the hot water heater tank will certainly be exposed to rusting. It is most ideal to have a water heater upkeep done once a year by a professional. Among the many elements of the water heater a specialist will consider is the problem of the anode rods, and will certainly have the ability to effectively change them as needed.
