Water heaters are one of the most reliable appliances to be found in a home, and they usually do their job quietly and without complaint. Indeed, most of them are tucked away in the basement, closet, or garage, and unless something goes wrong with your hot water, you rarely have cause to think about it. Unfortunately, there’s a flip side to that reliability: most people aren’t able to notice problems with their water heaters until the problem has gotten quite bad. In many cases, by the time you notice a problem, the entire water heater needs to be replaced instead of just repaired.
One important way to spot problems with your water heater before they bite you is to schedule annual service from a trained technician. they will check the water heater for signs of trouble, attend to little maintenance jobs like replacing the anode rod (which prevents rust inside the tank), and otherwise make sure that the water heater is functioning as it should. Doing so can also help extend the life of the system as well as helping it perform more effectively overall.
