The anode rod is an important component of your water heater installation. It is a steel core wire covered in aluminum, magnesium, or zinc. Each of these metals is less noble than the steel that comprises your tank lining, so each will rust before the steel. This protects your tank and lengthens its lifespan. It is essential that you check this rod every year for signs of deterioration. Here’s what you should know. 

Why Anode Rod Maintenance Matters

How Deterioration Causes Problems

The anode rod is screwed into the top of the tank, making it easy to pull out and check for deterioration. The rod is cylindrical when brand new, and will become thinner and more uneven as it deteriorates. If the deteriorated rod is not replaced, the steel lining inside the tank will start to rust. You may see reddish or brown water coming out of your hot water tap, or discoloration of your plumbing fixtures.

The deteriorated rod can also break off and bounce around inside the water heater. This will make a loud noise as it’s pushed around the tank and will crack the water heater lining. If this happens, you’ll likely need an entirely new water heater installation.

What Affects Its Lifespan

The average anode rod will last around four to five years before it needs to be replaced, but there are factors that will affect its lifespan. Having a water softener installed will shorten its lifespan, for example, since the sodium in the softener will dissolve it faster. Proper maintenance of your water heater installation will extend its lifespan. Have your plumber flush out the tank once or twice a year to remove corrosive sediment.
