Your water heater is one of the hardest working appliances in your home. Every time you make use of hot water in your home, which is probably multiple times a day, you’re relying on your water heater. That equates to a lot of wear and tear on the system, which in turn means a higher likelihood of problems occurring as the system gets older. Let’s take a look at some of the resulting water heater issues that you need to be aware of.
The reason your water heater doesn’t become a rusted-out husk a couple of years after installation is a part called the “anode rod.” The anode rod is a metal rod, usually made of magnesium or aluminum, which is inserted into your storage tank upon installation. While the anode rod is in contact with the water in the tank, it will attract the ions that normally cause rust. This process is called electrolysis.
While the anode rod is in the tank, it is protected from the effects of rust. That protection doesn’t last forever, though. After about a year, the anode rod will become so degraded that it will have to be replaced. At that point, the water heater will no longer be protected from rust. You should make sure that a professional checks your anode rod at least once a year to make sure it’s still functioning properly.
The dip tube is the pipe that vents all fresh water from the water line into the bottom of the water heater tank, where it will warm up faster and won’t be caught up with the hot water being pumped out of the tank from the top. If you have cold water coming out of your tap in bursts when you turn on the hot water tap, you may have a broken dip tube venting water into the top of the tank.
