What Causes Water Heater Failure?

Water heaters are especially important for households in urban areas such as Salt Lake City, Utah; hence, preventing water heater failure is paramount. To do so, it is best to call a professional water heater installation service. However, it is also necessary to know what kind of damage you are dealing with.

Here are some of the most common reasons for water heater damage and failure.


Leaks in a water tank can cause serious and costly damage to your home. A leak that bursts can flood your home with thousands of gallons of water, resulting in upwards of a hundred thousand dollars worth of damages.

Hence, it is important to regularly check your water tank and ask for expert help should there be signs of trouble. The first place to check for a leak is at the supply lines at the top of the water heater, especially if these are flexible supply tubes whose durability is not as strong as that of the tank.

Leaks may also occur at the water heater nipples, any of the pressure, temperature, and drain valves, or in the tank itself. When checking for a leak, it is important to check the external parts of the water heater first.

Should an external inspection not yield a possible leak source, then the leak is probably located inside the water tank, which is the most serious leak and denotes that the water heater tank needs replacing.


Corrosion is one of the major causes of damage in a water heater tank. This normally occurs on the sacrificial anode rods, which help prevent the water tank itself from corroding by attracting corrosive elements itself.

As this is a component that was designed to corrode, it lasts much shorter than a water tank and thus requires regular inspection and replacement, even when there are still no visible signs of leaks or damages.

The anode rods are typically easy to replace, and this is usually done as a part of routine inspections. Normally, it is recommended that you do an inspection every year. Should you find your anode rods corroded or worn down, simply ask for a professional’s help, and this will be remedied quickly.

Scale and Sediment


When “hard water” (water high in mineral content) is heated, the minerals are separated from the main water source and end up settling on the surface of the water tank.

The process is repeated each time water is heated, leading to a build-up of scale and sediment, which can prevent the anode rod from corroding (thereby increasing the possibility of corrosion on the water tank itself), damage other heating elements, and reduce the efficiency of the water heater.

To prevent buildup of too much sediment, it is best to flush the water out of the tank every year or twice a year. This is simple to do and can be done by yourself, or you can also ask a professional for help if you see fit.

While water heaters are normally said to have a lifespan of 8–12 years, this varies on how regularly maintenance is performed. In order to get the most out of your appliances, it is always best to familiarize yourself with warning signs of water heater failure and how to go about fixing them.
