Water HeaterProtect Your Tank Water Heater with an Anode Rod

An anode rod is also commonly referred to as a sacrificial anode, and with good cause. While it may sound rather dramatic, the anode rod does indeed sacrifice itself for the greater good within your hot water tank. If you use a tank water heater in Everett, WA, then it is very important that you have a good anode rod in place. In the following post, we’ll discuss precisely what the anode rod does, and why its role is so vital for your water heater as a whole. First, though, let us remind you that we are the company to call when you need any water heater services throughout the area.

What Is an Anode Rod?

An anode rod is a rod that resides within your hot water tank. Generally, the anode rod is composed of either aluminum or magnesium. Magnesium tends to be the preferred material for use in anode rods, but is also the more expensive. Consider the important role that your anode rod plays in protecting your hot water tank, though, that is certainly money well spent.

The job of the anode rod is simple and straightforward: to rust. That’s right. The whole purpose of an anode rod is to degrade in quality over time. Why is that so important? Well, it helps to prevent your hot water tank from meeting a similar fate.

The anode rod is more reactive to water exposure than the materials that water tanks are composed of. That means that the anode rod will rust and corrode before your tank does, protecting the integrity of your storage tank. There is no hard and fast rule as to how long an anode rod will last, with factors such as water hardness and temperature playing determining roles. Your anode rod should be assessed on a regular basis to ensure its continuing functionality.
