Your water heater is an essential part of your home's system. Water heaters have varying lifespans, but only if they are properly maintained can they achieve their full potential. You may notice a rise in utility expenses as the unit is near the end of its useful life.

It is also possible that the water heater's age may impact the water's temperature, making it unsafe to use.

1. Visible Corrosion On the Heater

Water heaters are subjected to hot water, which causes them to rust. You may find corrosion on the inside of the tank as well as on the outside of the unit. Beam corrosion is a form of corrosion caused by a buildup of minerals inside the tank, which can cause the tank to become brittle and crack.

These signs show that your heater is no longer efficient and that it may be time to replace it. Use caution around your water heater and be careful to not burn yourself.

2. Hot Water Is Not Consistently Hot Enough

If your water temperature seems lower than before, it could be a sign that the water heater is getting old. However, this can also result from sediment building up inside the tank. As a rule, if the water temperature isn't above 120 degrees Fahrenheit, it is not considered safe to use.

Excessive sediment in the water heater tank could be caused by a faulty water filter or low water pressure.

3. The Water Heater Makes Strange Clicking and Hissing Noises

According to Good Ol'Boys Plumbing which specializes in water heater replacement in Alpharetta, “one way to know if you need to replace your water heater is if it is ten years or older…however, you should be aware of these other signs which include strange noises, leaks, and rusty or cloudy water.” Continuous, loud clicking and hissing noises coming from behind the water heater could be a sign of a broken part or an issue with the unit's gas flow. These noises will likely become more frequent as the water heater ages. It can also be likely that the pressure release valve is faulty.

The lack of an efficient pressure release valve, or an improperly set one, can cause the water heater to fail. 

4. Water Appears to Be Leaking from The Bottom of the Tank

If you start noticing a puddle of water accumulating on the floor near your water heater, it could be a sign that the device is leaking. Leaks can be caused by worn-out or broken parts within the water heater, or they might result from a buildup of minerals in the unit's tank.

In either case, it is best to call a professional to inspect and replace the water heater before the leak worsens and causes more damage to your home.

5. Cloudy or Discolored Water

If the water coming from your faucets seems cloudy or discolored, it could be a sign of a problem with the water heater. The unit might be clogged or otherwise damaged, which can cause it to fail.

If you notice cloudy or discolored water, turn off the heater and consider replacing the device as soon as it causes damage to your pipes.

6. Your Hot Water Has Constant Repairs

As the water heater ages, it is bound to need repairs. However, if your water heater is constantly in need of repairs, this might be a sign that it is nearing the end of its lifespan.

If you notice that the water heater is causing you more time and money than it is worth, it might be time to shop for a new one.

7. Water Pressure Issues

If you are experiencing water pressure issues in your shower, it could signify a buildup of minerals in the water heater. Mineral buildup can clog the water heater and cause the device to fail.

Also, if the shower pressure in your home continuously drops as the water heater heats up, it could be a sign that the water heater is near the end of its lifespan.

If any of these issues sound like something your water heater might be experiencing, it might be time to replace it. A water heater is an essential part of your home, so it's important to know when it needs to be replaced.

If you notice any of the signs above, schedule an appointment with a reputable water heater company to have your water heater replaced.
