Water heaters are very sturdy systems, built to last for many years while being put under tremendous wear and tear. However, they will not last nearly as long if they are not properly maintained. Preventive maintenance is a good idea for pretty much any system in your home, but it’s especially vital for your water heater. Let’s take a look at why it’s so important to make sure that your water heater receives preventive maintenance at least once a year.
The Anode Rod
Water heaters deal with water every minute of every day, from the time they are installed until they are replaced. Yet, they are remarkably resistant to rust. Why is this? A part called the sacrificial anode rod is what protects the water heater tank from rusting. The rod is made of magnesium, aluminum, or zinc formed around a steel wire core. While it is in contact with the water in the tank, the rod will degrade over time. This attracts the ions in the water that cause rust, sparing the tank in the process. The anode rod will eventually degrade so much that it can no longer protect the tank, at which point it will need to be replaced. This is part of the reason why regular maintenance is so important.
Sediment tends to build up in the bottom of the water heater tank over time, especially in homes that have hard water problems. If this goes unchecked, the sediment buildup can eventually become so bad that it actually insulates the bottom of the tank from the heat from the burner assembly. Part of water heater maintenance includes flushing the tank, so that the sediment can be removed.
