Anode Rod Replacement

Water heaters are vulnerable to rust and corrosion, because of how steel in the water heater reacts to oxygen and moisture. This, the acidity of water, and heat can all hasten the process of corrosion.

By installing an Anode rod you can delay this process and extend the life of your water heater. Usually made from magnesium, the rod, succumbs to corrosion before other components of the water heater will. It then delivers electrons into the tank, creating an environment that prevents corrosion of the tank and its elements. Once corroded, the anode rod needs to be replaced to continue its protection.

When purchasing an anode rod, here are some things to think about.

There are two types, ones with a hex head and one with a nipple that goes on the hot water outlet. There are three options for material, aluminum, magnesium and zinc aluminum. Zinc aluminum is for water sources with sulfur, a.k.a. “Smelly water.” Aluminum and magnesium are interchangeable depending on the brand.

The hole is same size on all heaters, but some rods are longer or thicker. Going off the model and serial number is best way to ensure proper fit. If limited space above the heater prevents the installation of a standard anode rod, you can purchase and install the collapsible type.

To install...

1. Turn off water and fuel supply (gas or electricity) to water heater.
2. Partially drain the water heater around 6 inches to give you access but keep weight in the tank.
3. Locate the anode rod on the water heater; if necessary, unscrew and lift off the cover from the top of the heater.
4. Use a ratchet wrench and 1-1/16" deep socket to unscrew the anode rod from the heater. If it is the nipple type, you will need an adjustable wrench.
5. If the anode rod won't budge, slip a steel pipe onto ratchet wrench handle for extra leverage.
6. Lift out and discard the old anode rod.
7. Wrap Teflon tape around threads of new anode rod; insert anode rod into water heater and tighten with 1-1/16" socket.
8. Turn the water and fuel supply to the water heater back on.
