How to Tell if Your Water Heater Needs to Be Replaced

Did you know that about 8% of households replace their water heaters annually? While in the majority of households, the availability of warm, running water is vital to everyday living, there are issues that can arise with any type of water heater. From showers to cooking to laundry, the average water usage per household can put some strain and wear on your water heaters.

Overtime, you’re bound to see some signs that your water heater needs to be replaced. Whether it’s due to usage strain or the age of the tank, water heaters don’t last forever. While you can help prolong the life of your water heater with annual maintenance, you’ll definitely still have to replace it at some point in it’s lifespan. With that in mind, it’s important to be able to recognize the signs that it is time to replace your water tank.

Here are some of the ways you can tell that your water heater needs to be replaced:

    1. The Age of Your Device
    2. Broken Water Pump
    3. Rusty Water Runoff
    4. Water Heater Noise
    5. Leaking
    6. No Water Heat

The Age of Your Device

The lifespan of your water heater isn’t going to be immortal. The majority of water heaters last between eight to ten years, however you may need to replace your heating unit beforehand. While most homeowners are unaware of when a water heater reaches its expiration date, you don’t have to be like the majority! Be sure to check in on the age of the water heater in your home to ensure proper maintenance and keep up with a proper timeline.

Broken Water Pump

Sometimes, your water heater specifically might not be the issue. If you’re noticing any discrepancies in water temperature or pressure, you could have a broken water pump. Not all water heaters have a life expectancy of up to ten years, and pieces within your water heater may break along the way. To be sure you’re dealing with a broken water pump, contact a local plumber to assess the real issues before it is too late. If this is the case, you likely won’t have to spend as much money buying an entire new water heater for your home.

Rusty Water Runoff

Something to look out for when evaluating the wellbeing of your water heater is rusty water runoff. While steel tends to be one of the strongest materials, it has a rusty weakness. When corrosion takes hold on a steel surface, it slowly begins to spread and eats through the material in certain spots. This can cause harm to the entire water heater system and create various leaks and other issues.

If you start to notice rust appearing in the hot water from your faucets, chances are you have a rusty water heater. On heaters used past their expiration date, rusting is inevitable, but if you notice this beforehand, you’ll definitely want to have the problem properly assessed by a plumber.

Pro Tip: If you spot rust around the water inlet or pressure relief valve on the heater, it’s likely that rust has also taken hold inside the tank. You’ll want to immediately assess the damage and replace the water heater in your home.

Water Heater Noise

Another telltale sign of a dying water heater is when you begin to hear noise from the tank. As your water heater ages, rumbling noises will start becoming louder and louder as the tank heats up water. In households that consume large amounts of hot water, this problem is likely to increase tenfold. Be sure to keep an ear out for any odd sounds coming from your water heater.


As your water heater nears the end of its life expectancy, there’s an increased chance that you’ll begin to witness water on the floor around your tank. If you do begin to see water, it generally means your heater is probably leaking.

Depending on where you have the water heater located inside your house, a leak could result in significant property damage. This is a situation where you will want to find a solution immediately, and likely will have to replace your water heater.

No Water Heat

A telltale sign that your water heater needs to be replaced is experiencing a lack of warm water. Without warm water, you probably won’t want to wash your hands or take showers. You also will likely be unable to properly clean dishes or run your laundry machine. If you begin to experience a loss of hot water, your water heater may have a misadjusted thermostat, a broken heating element, or a tank that’s too small for the size of your house.

Some of these problems are easier fixes than others, but with the help of a professional, you can determine for sure if your water heater needs to be replaced. Learn more about our water heater services in Middle Tennessee.
