Water heaters are a necessary part of any home because they supply hot water for all of your daily needs. Although water heaters last many years, they don’t last forever, and it’s important to know what to do when they start to fail. Some issues with water heaters can be easily repaired, while others might indicate a full replacement is needed.

In this blog, we will discuss some of the most common reasons why water heaters tend to go out. We’ll also provide tips on how to prevent them from failing in the first place, and what to do if your water heater does break down.

Sediment Build-Up

One of the most common reasons water heaters fail is because of sediment build-up. Over time, mineral deposits can accumulate in the bottom of the tank, causing the heater to work less efficiently. This can lead to higher energy bills and eventually, a complete breakdown of the unit. To prevent this from happening, it’s important to flush your water heater regularly. You can do this yourself by draining the tank and then refilling it with fresh water.

Loose Parts

Another reason water heaters fail is due to loose parts. If any of the components inside your water heater are loose, it can cause serious damage to the unit. This is why it’s important to have a professional inspect your water heater on a regular basis. They will be able to identify any potential problems and fix them before they cause permanent damage.


Water heaters can also fail due to rust. Rust is a common problem with older water heaters, and it can eventually lead to leaks. If you notice any rust on your water heater, it’s important to have it repaired as soon as possible. Otherwise, the rust will continue to spread and eventually cause the unit to fail completely.

Old Age

Water heaters, just like many of your other appliances, are meant to last many years, but they aren’t meant to last forever. After about 12 years or so, your water heater might start slowly breaking down due to old age. Warning signs might include a pilot light that constantly flickers or fluctuating hot water. Instead of paying for frequent repairs, you’re better off replacing your water heater.
