We’ve written a lot about how important water heater maintenance is for your system, and how you should schedule it once a year. What we haven’t spent a lot of time on, though, is how water heater maintenance specifically protects your system from issues that threaten it. So, with that in mind, let’s go over some of the specific ways that water heater maintenance keeps your system running properly.
Checking the Anode Rod
All tank varieties of water heater contain an anode rod of some kind, sometimes even more than one. The anode rod is a metal rod designed to slowly degrade when in contact with water. As the rod degrades, it attracts the ions that cause metal to rust. So, as long as the anode rod is in the tank it protects it from rusting. Once the rod has all but degraded away, though, the tank will once again be susceptible to rust. You should have the anode rod checked at least once a year, and replaced if necessary to continue protecting the tank. Annual maintenance is the best time to get this done.
Flushing the Tank
If you have hard water in your home, sediment will start to build up on the bottom of the water heater tank. Eventually, the sediment buildup can become so bad that it actually insulates the tank from the heat generated by the burner assembly. In order to prevent this from happening, you’ll need to have the tank flushed out on a regular basis to get rid of the sediment. This is commonly done during maintenance appointments.
