Sacrificial Anodes

Sacrificial Anode – Essential for Water Heater Protection

A sacrificial anode is a crucial component in water heaters, designed to protect the tank from rust and corrosion. Made from a steel core coated in metals like magnesium, aluminum, or zinc, it corrodes before the tank itself does.

How It Works

Anodes are installed at the top of hot water tanks. Their softer metal makeup allows them to corrode first through a process called electrolysis, effectively “sacrificing” themselves to preserve the tank.

Maintenance Tips

For best results, check and replace the sacrificial anode every 4-5 years, or as recommended for your water quality and usage. This simple step can extend your water heater’s life, helping prevent costly repairs and leaks.

By keeping up with anode maintenance, you ensure reliable protection for your water heater.
