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

Limescale could form if the anode is too close to the hot water tank walls and the current flows too fast between the two materials. Corro-Protec, unlike other powered anode, have a design that prevents this kind of reaction.

The length of a powered anode rod does not affect the protection of the hot water tank because it is the electrons projected by it that provide protection against corrosion.

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 :

Some people also say that the earth is flat! Seriously, these people (competitors) play on words. Our anodes are made from titanium and coated with MMO, which improves their performance. Learn more in our blog post : Tests of Powered Anode 

Some people say that Corro-Protec Powered Anode Rod is not made of titanium. Is it true? 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

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.

How do you install the Corro-Protec powered anode rod in a Bradford White Water Heater that have an integrated magnesium anode? 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.

Maintenance

A water softener that is not properly adjusted allows extra salt to flow through the pipes and / or into your water heater. The current sent by the powered anode will turn a part of the excess of salt into chlorine and a smell will occur. This will mean that your softener must be readjusted!

How is it possible?
Chlorine is produced by passing an electric current through a solution of brine (common salt dissolved in water). This process is called electrolysis.

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

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.

The rectifier of my Corro-Protec system doesn't work, why? 7

The Corro-Protec Powered Anode Rod only needs a few amperes to operate. Your electricity cost will be less than $2.

Warranty

Yes, all Corro-Protec system come with a 20 years warranty. To register your Corro-Protec, please complete the following form: Warranty.

Is there a warranty on the Corro-Protec System ? 8

No, such a leak probably results from an abnormally higher water temperature than the safety standard, caused by the malfunction of the water heater thermostat. If something like this happen, please contact us.

There is a leak between the plastic compartment and the stainless steel part on the Corro-Protec. Is this normal? 9
