Corrosion is a process that can happen in many ways, but it always leads to the same outcome: destruction. In the case of water heaters, corrosion can cause serious damage and eventually lead to failure. Today, Wellbrook Plumbing, the trusted plumber in Port Colborne, ON, discusses what causes corrosion in water heaters and what the different types of corrosion are.
Oxygen Levels in Water
The most common type of corrosion that occurs in water heaters is caused by the presence of dissolved oxygen in the water. When the water heater tank is filled with water, the oxygen in the air and water combine with the metal in the tank to form a weak oxide layer. This layer is called rust. Rust has a reddish color and forms on the outer surface of the metal tank. As time goes by, this layer will continue to grow and will eventually cause the tank to fail. Regular maintenance after water heater installation is key to preventing rust in your heater’s tank.
Another type of corrosion that can occur in water heaters is known as electrolytic corrosion. This occurs when an electrical current passes through the metal in the tank, causing it to corrode. This can happen in many types of water heaters, but is most common in electric water heaters. When you notice signs of corrosion in your heater, schedule prompt water heater repair in Port Colborne, ON.
The final type of corrosion that can happen in water heaters is known as pitting. Pitting is caused when the metal in the tank becomes pitted, causing water to leak out of the tank. This type of corrosion is usually caused by a combination of factors and can be prevented with regular maintenance or water heater replacement.
