Question 1

What is a magnesium anode used for in water heaters?

Accepted Answer

A magnesium anode protects the water heater tank from corrosion by corroding instead of the steel tank walls. The CBM 26X400 mm anode is installed inside the tank to extend its operational lifespan in freshwater systems.

Question 2

When should I replace a magnesium anode in my water heater?

Accepted Answer

Replace your magnesium anode every 2–5 years, depending on water hardness and usage. Inspect it annually; if it's less than half its original diameter, replacement is due. The CBM 26X400 mm fits standard residential and light commercial heaters.

Question 4

How do I install a magnesium anode in a water heater?

Accepted Answer

Turn off and drain the heater, then unscrew the anode rod from the tank top. Insert the new CBM 26X400 mm anode, ensuring a tight seal, and refill. If uncertain, consult a licensed plumber—improper installation risks leaks or reduced protection.
