Leaks And Loud Noises: Signs You Need A New Water Heater

 Your water heater is the silent workhorse of your home, helping you to enjoy warm showers and providing hot water on demand for washing dishes. Like any appliance though, it doesn’t last forever - most water heaters have a lifespan of 8 to 12 years. It’s useful to know the warning signs of a failing water heater before it completely breaks down, or alternatively triggers a flood or energy bill spike. Below are just a few clues that your water heater might be due for a replacement. 

Water leaks

An obvious red flag is visible water pooling around your heater. This is often caused by corrosion within the inside of the tank - rust can eat away at the metal over time and eventually seep out. What may begin as small drips could eventually turn into major flooding, damaging your home’s floors and walls. Water heater repair experts will be able to confirm whether a full replacement is needed. 

Reddish water

If water is coming out of your faucets with a reddish-brown hue, it could be a sign of rust in the pipes or in your water heater. This means that corrosion is happening and that your water heater could be about to start leaking. Flushing the tank out will usually offer temporary relief, however if the reddish water returns, you’ll need to consider replacing your water heater. It’s worth noting that mineral sediment from hard water can also be a culprit, which may be accompanied by limescale on shower heads and faucets. Water filtration systems can be installed to reduce mineral sediment build-up. 

Strange noises

Your water heater shouldn’t sound like a popcorn machine and it certainly shouldn’t sound like a rumbling thunderstorm. If you’re hearing banging and rumbling, it could be a sign of water heater failure. Try flushing out the water heater to see if the noise is caused by sediment. If the noises persist, it might be time for a replacement.

Hot water shortages

Running out of hot water mid-shower? If your supply is inconsistent or shorter than usual, it could mean that the water heater is failing. The cause could be sediment or failing heating elements - which are sometimes fixable.  But if your water heater is also very old, you are likely better off replacing the whole appliance. Hot water shortages can also occur after a home has undergone major improvements such as bathroom additions - it’s possible that your water heater may no longer be equipped for the increased demand of your home.

Pressure issues

Low or fluctuating water pressure can have many causes including mineral build-up in pipes or a failing pressure relief valve. However, it can also be caused by a failing water heater. A good way to determine if the water heater is the culprit is to test both the cold and hot water - if the cold water pressure is fine, but the hot water pressure is low or unpredictable, it’s likely a water heater fault. Consider replacing your water heater if it’s an older model.
