Is My Water Heater Broken?

Your water heater is one of the most important appliances in your home. It’s the key to hot showers, hand-washing 𑁋 pretty much anything that requires hot water. Water heater maintenance is essential, and there are usually clear signs that yours needs a checkup. Here’s what to look for:

Signs Your Water Heater is on the Fritz

Incorrect Water Temperature

Your water heater has one essential objective – to heat your water. So if you notice a drop in temperature, no hot water at all, fluctuations in temperature, or anything that seems out of the ordinary, it’s likely that your water heater is to blame.

There are several culprits for these issues, which usually depend on the type of unit you have, the fuel it uses, and the system’s age. Often incorrect temperatures mean the burner is malfunctioning or the unit’s thermostat is off.

If you notice you have hot water for a while and then it suddenly runs out (faster than usual), it likely means a water heater issue. The exact problem will depend on whether you have a tank or tankless unit. Tank units have many gallons of hot water at the ready, so it is unlikely to run out during everyday activities.

Unclear Water

Rust in your water can be a hazard to the health of you and your family. While there are several causes of rust, if you only notice it appear while running hot water, it may be an issue with your water heater. The tank may have rust, or there are sediments dropping into the water, neither of which is good.

You may also experience cloudy water that has a smell. This could be due either to mineral deposits collecting in your water heater or bacteria infiltrating the unit. If you notice this symptom, make sure to call a local plumber to address the issue.

Murky water not only poses damage to your health but will significantly decrease the life of your unit if left untreated.


All leaks need to be handled right away. Usually, a water heater leak will show itself around the base of the unit. Not all leaks are apparent, which is why seasonal maintenance can help alleviate more significant problems down the road.

Leaks can cause water damage to your home if left alone and can even be a hazard to other nearby appliances. It can also cause corrosion to the outer part of the water heater.

Noises Coming from the Unit

Some noise is normal, like the buzzing of an entirely operational appliance. But unusual noises should make you think twice. Know what your unit sounds like normal, so it’s easier to diagnose a deeper noise issue.

Reliable signs of a problem include strange noises coming from inside the unit. If they become louder and more frequent, it’s time to place a call with your local plumber.

The Importance of Annual Maintenance

Getting regular maintenance on your water heater can prevent many of these issues from occurring. As tanks age, they become more vulnerable to problems and will likely need repairs. The more robust your maintenance schedule, the more money and headaches you can save on water heater repairs down the line.

Professional plumbers can assess your unit and its performance (and take any questions you may have), which allows them to get a full picture of any possible issues. They’ll also diagnose problems that may not be obvious to homeowners but are standard for plumbers who work with water heaters every day.

A plumber can also help you decide whether it’s time to replace your water heater rather than continue with repairs.
