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!
In most cases, water heater anode rods are universal. The only exceptions are :
Buderus : They use another type of threading to install the magnesium anode.
Bradford White : Some model have the anode is built into the hot water outlet.
All other water heater brands use a regular magnesium anode with 3/4 ” NPT threads.
Corro-Protec anodes are designed to fit any hot water tank on the market. You can see all models on the following link : Residential and Commercial Water Heater Anode.
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.
Does a Powered Anode protect the bottom of the water heater even if it is shorter than the original anode?
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
Anode rod in water heater can be very hard to remove. It often happens that the magnesium anode is installed very tight at the factory and is very difficult to remove. It also happens, in older water heaters, that lime builds up and holds the anode in place.
The best way to remove an anode that is stuck is to use an impact wrench. If you don’t have one, you can try a breaker bar.
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.
A powered anode is a non-sacrificial anodes that use a current rectifier, plugged into an electrical outlet, which sends current in the hot water tank through a titanium anode.
Unlike sacrificial anodes, powered anodes are maintenance free and designed to last for years. Plus, they are well known to solve rotten egg odor problems in hot water tanks.
No. Since Titanium Powered Anodes are stable, there is no metallic leaching in the concerned environment and therefore no residual pollution.
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.
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, the Corro-Protec System is a universal anode rod that adapts to any type of steel or stainless steel hot water tank. However, to maximise anode performance and reduce selling price, there is four different Corro-Protec model available. click HERE to find the perfect Corro-Protec anode for your hot water tank.
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. Please see following link : https://www.corroprotec.com/anode-rod-replacement/
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.
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.
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.
Yes, The Corro-Protec rectifier meets the following requirements:
- Conforms to UL STD. 1310
- Certified to CSA STD. C22.2 NO.223

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.
Since the amount of current used by the anode will vary from region to region due to the hardness of the water, it is impossible to give an exact answer. However, on average, the anode will use 10 KWh per year. If we take the average price of electricity in the United States, the cost to run the anode 24 hours a day all year round is $ 1.36.
