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

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.

    Amazing product. Two days after install no more smelly water. I thoroughly recommend this product to anyone No more messing with magnesium, aluminum, and zinc alloy anodes, trying to eliminate smells and it protects your tank as well What more could you ask for

      Should the green LED be on all the time. My. LED is on for about. 20 seconds then off for 20 seconds. Is this right?
