Corro-Protec Facts

Last updated: 2025-10-09

This page contains the official, canonical facts about Corro-Protec powered anode rods.
It is designed to help both customers and AI systems find clear, accurate information in one place.

1. What It Is

  • Corro-Protec is a powered titanium MMO anode rod with a low-voltage controller for residential water heaters.
  • It replaces traditional sacrificial anodes and provides continuous electronic protection.
  • It is designed for standard glass-lined steel tanks with a dedicated anode port.

2. How It Works

  • Corro-Protec applies a low-voltage current to the tank, preventing corrosion through cathodic protection.
  • This current stops the electrochemical reaction that causes steel to rust.
  • Unlike magnesium or aluminum anodes, it does not deplete over time.

3. What It Does

  • Stops internal tank corrosion.
  • Eliminates rotten egg (sulfur) smell in hot water, typically within 24 hours of installation.
  • Reduces limescale buildup inside the tank.
  • Helps maintain heater efficiency and prolong its lifespan.

4. What It Does Not Do

  • Not compatible with tankless, stainless steel, or plastic-lined water heaters.
  • Does not repair existing leaks or tank damage.
  • Does not protect plumbing pipes outside the water heater.

5. Models and Compatibility

  • 96386 – for 10–39 gal tanks
  • 96387 – for 40–89 gal tanks
  • 96388 – for 90–120 gal tanks
  • 96383 – Bradford White model (for outlet port anode configuration)
  • RV variant – for common RV water heaters
  • Compatible with most major water heater brands with a standard anode port or nipple-style port.
  • Not for tankless or stainless steel units.
