woman-covering-ears

Let’s say you are doing the dishes this afternoon and you notice a strange sound whenever you turn on the hot water tap. Or maybe you go to check on the laundry and your hear odd noises from the water heater while switching your clothes into the dryer. What is going on with the water heater? Why has it gotten so noisy? And what do those noises mean?

These are all questions residents in the area may face at one time or another. We have the answer and the services you need.

When your water heater in Columbia, SC starts to get a bit noisy, you can rely on us to diagnose the core problem and fix it ASAP.

Concerning Sounds to Hear From Your Water Heater

There is more than one sound you don’t want to hear from your water heater system. If you hear any of these noises, you should reach out to a professional technician on our team to get your system checked out.

  • Crackling: This is a common sound to hear if your water heater hasn’t been flushed in a long while. This is because sediment has started to settle and collect at the bottom of the water heater, which is causing a struggle for the system in the heating process. The crackling noise is caused by hot water being forced up through that sediment layer.
  • “Kettling” or whistling: What is that whistling noise? If it isn’t the tea kettle on the stove, it may be due to a problem in the water heater. This is another noise that is created by sedimenatary build-up in your water heater system. Make sure to get your system checked if you notice this noise.
  • Screeching: Don’t worry, your water heater isn’t going to explode. But it isn’t good that it has started to make this sound. This can indicate that the water heater is struggling with waterflow restriction due to a valve that may not be opening properly. Make sure to get these parts fixed ASAP.
  • Sizzling or hissing: This is another sediment-build-up-based noise. This time it can indicate that sediment has started to collect on the heating elements in your water heater, which can lead to serious problems.

Unsurprisingly, the noises listed above aren’t the only signs of trouble that your water heater may exhibit. Aside from bad noises, signs of leaks, reduced water pressure, and poor temperature control are also indicators that your system is struggling.
