Frequently Asked Questions


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.

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.


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


Yes, CORRO-PROTEC is a universal system that adapts to any type of 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 ‘T’ 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.

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, it is possible to install CORRO-PROTEC by yourself. Download the installation document from the following link. You can also find the guide directly in the box of your CORRO-PROTEC.

Yes, CORRO-PROTEC can be installed in a used water heater. However, we recommend the installation of a CORRO-PROTEC during the first 4 years of wear of the hot water tank to maximize its efficiency.


A water softener that is not properly adjusted allows extra salt to flow through the pipes and / or into your water heater. The impressed current anode of the CORRO-PROTEC system will turn 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 CORRO-PROTEC anode. 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 it is.

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

To ensure that the 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 average consumption of the anode is 0.1314 KWH per year, which is less than $ 0.10 annually!


Yes, we offer a 20-year warranty on our Corro-Protec system. To register for our warranty, please complete the following form: Warranty.

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.
