The How’s and Why’s of Water Heater Maintenance - Wisler Plumbing & Air

Most people don’t think about their water heater and how it needs maintenance, but it’s just like any other piece of equipment. Our car, house, and even our own bodies need maintenance. If we don’t exercise and eat healthy, we’re probably not going to last as long. If we don’t change the oil in our car, it won’t last as long, either. Maintenance is just a good idea, but it can also be a way to save money.

Most people don’t realize that buildup occurs in the water heater, especially if there’s hardness in the water. Calcium is dissolved in hard water, but as it is heated, the calcium solidifies and accumulates either on the element of an electric heater or on the bottom of a gas water heater. The layer of calcium buildup acts as an insulation barrier, which means the water heater has to work harder to do the same job. Therefore, it will cause over-payment on your electric or gas bill. To help reduce buildup, we will flush the water heater.

The tank that holds the water is kind of like a settling tank. If there’s debris, sediment, or calcium, it’s going to settle to the bottom of the heater. The tank will corrode very quickly if it’s got a bunch of sediment and gunk at the bottom. That’s going to cause premature failure, and we solve that by flushing the tank as well.

We also check the anode rod when we maintain a water heater. (The owner’s manual says this should be done as part of proper maintenance.) The anode rod is there to protect the metal that makes up the tank itself. Once the anode rod is completely depleted, there is no protection left. If we replace the anode rod when it depletes, we can add a couple of years to the life of the water heater (which saves you money).
