Frequently Asked Questions About Powered Anode Rod

This section contains all the frequently asked questions about Corro-Protec Powered Anode Rods. These systems are also called ICCP system or impressed current anode. Can't find the correct answer? Contact us!

Anode Rod

Yes, it is even highly recommended to install an imposed current anode if you have a water softener.

The water softener generally makes the water more aggressive to the tanks, which reduces the life of your hot water tank and creates a more conducive environment for the development of Sulfur Reducing Bacteria that creates the rotten egg smell in hot water. The Corro-Protec Powered anode rod will automatically adjust to provide optimum rust protection.

Limescale may form if the anode is too close to the walls of the hot water tank and the current flows too quickly between the anode rod and the tank. Corro-Protec powered anode, unlike other anodes, has a design that prevents this type of reaction. Indeed, the white plastic present in the top of the titanium anode prevents this kind of reaction and ensures that the anode is well positioned in the tank.

The answer is YES. Since the sacrificial anode must sacrifice itself to protect the hot water tank, it is important that the anode is large enough to last for several years. However, the powered anodes rod do not work in the same way, so they are much smaller.

A powered anode related to electricity being fed into the anode to impose a flow of current rather than relying on natural electrolysis. The length and size of the anode, as well as the current sent by the rectifier will influence the life expectancy of the anode. Corro-Protec anodes have been designed to work for more than 40 years, no matter how hard your water is. In order to know more about the lifetime of the current anodes, I invite you to visit our blog post: Tests of Powered Anode

Does a Powered Anode protect the bottom of the water heater even if it is shorter than the original anode? 1

Yes! Corro-Protec Powered Titanium Anodes are recognized by some insurance companies :

Our Corro-Protec anodes are made from titanium and coated with MMO, which improves their performance.

The stability of MMO (mixed metal oxide) coated titanium anodes have been used for almost 30 years. MMO coated titanium anodes are used in various environments such as seawater brackish water fresh water carbon backfill and concrete.

Is the Corro-Protec anode made of titanium? 2

Health

No. Since Titanium Powered Anodes are stable, there is no metallic leaching in the concerned environment and therefore no residual pollution.

Installation

Yes, Corro-Protec Powered Anode Rod can be installed in a used water heater. However, we recommend the installation of a Corro-Protec during the first 5 years of wear of the hot water tank to maximize its efficiency.

Can I Install a Powered Anode on an Older Water Heater? 3

Some fiberglass hot water tanks require anodes to protect certain metal parts in the tank. If your tank is equipped with a magnesium anode, you can install a Corro-Protec.

In most cases, these tanks do not have anode and do not need any additional protection.

Yes, Corro-Protec Powered Anode Rod is a universal system that adapts to any type of steel or stainless steel hot water tank. Five different Corro-Protec are available depending on your water heater:

– 10 to 30 gallons
– 40 to 80 gallons
– 90 to 120 gallons
– Corro-Protec Oil
– Corro-Protec Stainless

Since Bradford White water heaters have the magnesium anode built into the hot water outlet, we need to do a few extra steps to install a powered anode rod.

Here is one way you can install the Corro-Protec anode rod :

1. Remove the safety valve from the top of the tank.
2. Insert the Corro-Protec anode instead of the safety valve
3. put a Tee adapter on the water heater outlet
4. Add the safety valve to the top of the adapter and connect the outlet to the other end.

The safety valve is sometimes on the side of the tank. If this is your case, you will be able to install our products without problems, because the Corro-Protec anode can be installed both vertically and horizontally. If the anode is too long, you can bend it or cut it without affecting its performance.

Even if you install the Corro-Protec anode to eliminate sulfur odors in your hot water, you do not need to remove the magnesium anode.

How do you install the Corro-Protec on a Bradford White Water Heater? 4

Yes, it is possible to install Corro-Protec by yourself. Visite our Replacement page to learn how to replace your magnesium anode rod by our powered anode rod in 15 minutes! You can also find the guide directly in the box of your Corro-Protec.

The answer is no and that is why Corro-Protec offers different models adapted to tank sizes.

If your water heater has two anodes, you can replace one of them with our Corro-Protec imposed current anode and leave the other one in place. Even if you install the Corro-Protec anode to eliminate the rotten egg smell in your hot water, you don’t need to remove the second magnesium anode.

Maintenance

It is possible to find rust residues in your hot water after the installation of a Powered Anode Rod. The anode cleans the tank, so residues will be present in the water throughout the cleaning process.

Rectifier

Yes, because the voltage adjusts automatically depending on the resistance of your water. A very low voltage means that your water is very conductive and the anode does not need to send much current to provide adequate protection.

Is it normal to read a current lower than that indicated on the Powered Anode rectifier? 5

Yes, The Corro-Protec rectifier meets the following requirements:

  • Conforms to UL STD. 1310
  • Certified to CSA STD. C22.2 NO.223

If you want to learn more about the tests performed on our anodes, visit : https://www.corroprotec.com/blog/tests-of-powered-anode-iccp/

Is the Corro-Protec rectifier certified? 6

To ensure that the cathodic protection works, the following conditions must be met:

  • The rectifier must be connected
  • Corro-Protec must be connected to the rectifier
  • The negative side must be installed on the water heater, as indicated in the instruction manual.
  • The water heater must be functional (filled and operational)

If the above conditions are met and the indicator light is not lit, please contact us to complete a claim.
