We’ve written pretty extensively about why it’s a good idea to schedule water heater maintenance at least once a year. However, it’s been a while since we’ve explained some of the actual procedures that are a part of water heater maintenance. It’s good to have some idea of what actually happens during a water heater maintenance appointment, as it helps illustrate why maintenance is so helpful. So, let’s take a look at some common water heater maintenance procedures, and how they can help your system.
Checking the Anode Rod
The anode rod is a long metal rod that is inserted into the water heater storage tank. The anode rod degrades over time, and as long as it degrades it protects the tank lining from rusting. The protection isn’t permanent, though. The anode rod only lasts around a year before becoming so degraded that it can no longer protect the water heater. At that point, it will need to be replaced. As part of a standard water heater maintenance appointment, your technician will check the anode rod and replace it if necessary.
Flushing the Tank
Over time, sediment can build up on the bottom of the tank. The more calcium and magnesium your water has in it, also known as its hardness, the more sediment can coat the tank. Eventually, the sediment buildup on the bottom of the tank can build up so much that it insulates the water inside from heat. Your water heater will not be able to actually provide hot water if that happens. Water heater tanks are often flushed out during maintenance visits, in order to get rid of the sediment and make sure that the system can operate properly.
