Tests of Powered Anode Rod (ICCP System)

If you are visiting this page, it is certainly because you have discovered imposed current anodes or because you want to know more about cathodic protection. We frequently respond to erroneous information due to a lack of knowledge or due to the association with atmospheric corrosion, which is different from the corrosion in an area where the oxygen level is weak, like in water or in soil.

Cathodic protection is regulated.

In order to provide an effective cathodic protection system to protect a structure such as a residential hot water tank, it is important to ensure a level of polarization of the structure so that the corrosion is permanently neutralized. 

The oil and gas industries are standardized and must follow protection criteria established by organizations such as NACE or CERFRACOR to continue operating in their respective domain. These organizations train and certify personnel working in the field and show them methods and practices which allow them to effectively control the external corrosion systems of metal pipes which are buried or submerged.  These methods and practices are equally applicable to many other subterranean or submerged metallic structures.

We are working with the RP0169-2000 standard for cathodic protection. The CORRO-PROTEC anode system meets these effectiveness criteria.  The tests and design studies were made on hundreds of reservoirs tanks before being marketed.

Imposed current anodes have a determined duration of determined life span. 

The effective life span test was done in an independent laboratory recognized by NACE. 

The effective life span of the CORRO-PROTEC cathodic protection system was subjected to aging tests in compliance with the NACE TM0108-2008 regulation standard and supervised by a level 4 NACE CP specialist

The CORRO-PROTEC systems were submitted to this test in 2010 by the DNV GL Laboratory in Columbus, Ohio.  The results determined that the imposed current anodes are designed for an effective durationof more than 20 years, regardless of the condition of the water in which they are used.

The materials used are of the greatest importance.

As well, in order to maintain the high level of quality of our products, more tests are carried out:

X-ray test of the MMO anode coating

In order to ensure the density of the MMO coating on the anode, x-ray tests are carried out to highlight the uniformity of the coating layer on the titanium substrate.

Surface test

A comprehensive test to verify that the coating is smooth, black, and without any scratches to the naked eye.

Sealing Test

The anodes are subjected to pressures up to 340 PSI in order to ensure their water tightness and reliability.

Rectifier

In addition, the rectifiers used by CORRO-PROTEC have been tested and approved by different organizations such as ETL and CE. Our current rectifiers are compliant with the following standards:

Our anodes have been manufactured and tested for over 12 years, using rigorous and constant procedures in order to offer you a more reliable product.  Since we continually perform quality testing, we can offer one of the best imposed anode currents on the market.

    Does it matter if the ground is placed on a screw on the top of the water heater or on the bottom of the water heater?

      Hello Troy, it doesn’t make any difference. Just make sure the green light on the rectifier is ON!

    I installed the powered anode in a natural gas fired tank heater that was only 6 months old. Water source is deep well and treated by town water treatment plant; is hard but no sulphur. I have it pass though a particle filter and then a water softener. I flush it every 3 months. I hope to keep this tank for at least 20 years. After a few months of operation, I decided to measure anode current and voltage. Readings are 15.0 mA, and 2.87 V.
    Questions: Are these readings normal? Is there any point in taking periodic measurements of current and voltage? Are changes a sign of impending failure?

      Hello Peter, Yes, these measurements are perfectly normal! The voltage will vary to ensure an amperage of 15 mA. You just have to check the green light on the rectifier. If it is on, it means that the impressed current anode is functional and that your hot water tank is protected.

    Eric Sobocinski thanks for asking that question! I was worried about that and now know the green light means it is functioning properly.

    I installed the Corro-protect Rod 3 weeks ago, prior to having it I would put Hydrogen peroxide in my Hot water tank and it would eliminate the smell, but only temporarily and recently the smell was coming back within 10 days, which had me look into and buy this product. I am pleased as I am well passed the 10 day mark (20 days) and no smell yet!
    I plan on posting an update at the 6 month mark
    So far I’m really pleased and if this keeps the smell away long term it will easily be the best $175 I ever spent!

    Hello.

    I am a potential residential water heater customer. It seems from the installation instructions that the Corro-Protec water heater powered anode has an indicator light on its rectifier. Does that light indicate proper function or does it merely indicate power?

    I ask because I currently have a competitor’s product that has failed twice in two years (under warranty). The second time it has failed, it’s indicator light has remained on even though there is no voltage at all (not even a millivolt) to the tank leads. I want to make sure that my next powered anode has an indicator light that actually verifies that the anode is working.

    Thanks for your information

      Hello Eric,

      The green light indicates proper fonction of the system. By exemple, if you plug everything and there is no water inside your tank, the light won’t work because the system is not active.

      Hope this helps,

      Vincent

    Recently purchased and installed your product. I had used a aluminum/zinc anode in my previous tank and still had a bad smell for 24 years. About a week after installing a new hot water tank, the smell returned. After installing your powered anode in the new tank, the smell went completely away. The only problem I had was the same as noted in many of the comments. That was getting out the original anode. Even though the tank was new the original anode acted like it was welded in. After many tries with a large ratchet and a breaker bar with no luck, and a pneumatic impact wrench with no luck, I borrowed a 1200 PSI battery powered impact from my local tire dealer. That broke it loose and the rest was a breeze. Thanks.
