What are the Signs that Your Water Heater is about to Break

A properly functioning water heater is essential to your plumbing system, providing hot water for showers, washing dishes, and laundry. But like any appliance, it can break down over time, causing inconvenience and potentially costly damage. That’s why it’s important to know the warning signs that your water heater is about to break, so you can take action before it’s too late.

Several indicators indicate that your water heater is on the brink of failure, from strange noises to leaks and other issues. This article will explore the top signs that your water heater is about to break, so you can stay ahead of the game and prevent a plumbing disaster.

Be Aware of These 7 Warning Signs

  • Leaks

    Leaks are one of the most obvious signs that your water heater is about to break. If you notice any leaks around your water heater, it’s important to take action immediately. Various issues, such as a faulty pressure relief valve or a crack in the tank, can cause leaks. If left unaddressed, leaks can lead to flooding and water damage in your home.

  • Rusty Water

    Rusty or discolored water is another warning sign that your water heater is about to break. If you notice brown or reddish water coming out of your taps, it could indicate rust buildup inside the tank. Rust buildup can cause corrosion and weaken the tank, leading to leaks and other issues.

  • Age of the Water Heater

    The age of your water heater is one of the most crucial factors determining its lifespan. As a general rule of thumb, water heaters have a lifespan of around 10-15 years, depending on the type and model. If your water heater is approaching the end of its lifespan, it’s time to start considering a replacement. You can check the age of your water heater by looking for the serial number on the manufacturer’s label, which usually includes the date of manufacture.

  • Strange Noises

    Strange noises coming from your water heater can indicate several problems. The popping, cracking, or rumbling sounds could indicate sediment buildup inside the tank. Sediment buildup can cause the water heater to work harder than it needs to, reducing its efficiency and lifespan.

  • Inconsistent Water Temperature

    Inconsistent water temperature is another sign that your water heater is about to break. If you notice that the water temperature fluctuates between hot and cold, it could indicate a faulty thermostat or heating element. Inconsistent water temperature can be frustrating, especially during a shower, and it’s important to have it addressed before it leads to a complete breakdown.

  • High Energy Bills

    If you’ve noticed a sudden increase in your energy bills, your water heater could be the culprit. As water heaters age, they become less efficient, leading to higher energy consumption. If you notice a sudden spike in your energy bills, it’s important to have your water heater inspected by a professional. They can determine if it’s time for a replacement or if any other issues must be addressed.

  • Lack of Hot Water

    If you’re running out of hot water more quickly than usual, it could indicate a problem with your water heater. Several issues, such as a faulty thermostat or heating element, sediment buildup, or a leak in the tank, can cause a lack of hot water.


Knowing the warning signs of a broken water heater can help prevent costly damage or replacement. If you have all these signs in your home, it’s time to take action. Contact a plumbing professional for advice on how to fix the problem and prevent further damage.
