Just like any system, water heaters fail sometimes. There are a variety of reasons why your hot water heater might stop working. The best thing to do is be aware of what can cause this and how to fix it. And fortunately, you can do your part to prevent some common water heater problems. 

Read on to find out why hot water heaters fail and how to prevent it.

Sediment Buildup

During the process of heating up water, mineral deposits separate and settle at the bottom of your water heater tank. This sediment builds up over time, reduces the efficiency of your water heater, and ultimately, causes damage. It’s even worse with hard water.

How to prevent it: Make sure you flush your water heater at least once every year to help limit sediment buildup.

Corrosive Air

Water heaters draw in air for combustion. If the air quality is poor, it can cause problems. Corrosive air is especially dangerous as it corrodes your tank, which leads to the failure of your water heater. 

How to prevent it: Do not store corrosive substances anywhere near your water heater. This includes ammonia and bleach. 

Wrong Size Heater

If you have the wrong size of water heater in your home, you will likely have issues. For example, a water heater that is too small for the needs of your household will have to work harder than it should. This leads to breakdowns from overuse.

How to prevent it: Before buying a water heater, consult a professional HVAC company. They will help you make the right purchase for your home.

High Water Pressure

When the water pressure is too high, it can damage the water heater, your pipes, and appliances that use hot water. You might be able to check if the pressure is too high by looking at the side of your water heater to see if the overflow pump is leaking. 

How to prevent it: Always ensure your water heater’s water pressure is no higher than 80 psi. Also, replace the temperature and pressure relief valve as needed.

Internal Rust

Sacrificial anodes are metal rods used in water heaters to help prevent corrosion of the unit itself. Anode rods are corroded instead of your hot water heater (hence the name “sacrificial”). If you don’t replace them in time, your water heater will corrode.

How to prevent it: Anode rods last several years, but it’s still a good idea to check them once a year. If they look worn, it’s time to replace them. You can also call a professional to check for you.

Wear and Tear

Normal wear and tear eventually leads to water heater failure as the unit ages out. Water heaters usually last about 8-12 years, so you can expect to replace your unit anytime after that. If your water heater is old and in need of replacement, you might notice problems like rust, a bad heating element or a pilot light that won’t stay lit. 

How to prevent it: You can’t prevent your water heater from getting old and worn out. However, you can prevent problems by being proactive and replacing it with a newer, more energy-efficient model before you begin noticing signs of failure.
