Understanding the Role of the Anode Rod

The anode rod plays a very important role in determining just when you’ll need to contact a plumber in Albany, OR, from a trusted company like Linn-Benton Plumbing about a new water heater. Below, we take a moment to go over the role of the anode rod and what you need to know about this part.

Serving as a Sacrificial Rod

The temporary anode rod is a steel core wire coated with one of three possible metals – aluminum, magnesium, or zinc. The anode rod screws into the top of a tank-based hot water heater. Often described as a sacrificial rod, its main role is to draw corrosive minerals away from the exposed steel on the inside of the tank through a process known as electrolysis.

Anode Rod Problems

There are certain anode rod problems that should be reason enough to contact us about water heater repair in Albany, OR. One possibility is an anode rod that comes loose or breaks off. If this happens, the rod could bounce off the sides of the tank and damage the lining. Another possible anode rod issue is the wearing away of the rod itself. It’s best to replace the rod before it has completely deteriorated, which is why annual water heater maintenance checks can be so beneficial.

Signs of Anode Rod Failure

The anode rod is present at the time of the water heater installation. Once the tank is filled and the water heater is working, it will gradually corrode. This is ultimately what protects the water heater lining. Typically, an anode rod will last about 5 years.

A few signs suggesting your anode rod is nearly or completely worn away and require water heater services include:

  • Rust showing up in your water
  • Crackling and other odd noises coming from the tank
  • Leaking due to cracks within the tank lining from rust/corrosion
