Why Is My Water Heater Making Weird Noises?

Plumber working on a water heater

Have you ever been startled by strange gurgling, popping, or clanking noises coming from your water heater? It can be alarming to hear your otherwise quiet appliance suddenly making these odd sounds.

Before you get too alarmed, our skilled plumbers at Iceberg Home Services have put together this guide explaining the common reasons why water heaters get noisy. We’ll cover why your water heater might be making these weird noises and what they could signify.

What Causes Water Heaters To Make Noises?

To understand what causes a noisy water heater, it’s important to have a basic understanding of how water heaters work. In simple terms, the appliance contains a large tank filled with water that’s heated by either a gas burner or electric heating element.

When you turn on the hot water tap in your sink or shower, cold water from your pipes enters the bottom of the tank while hot water exits through a pipe at the top. This constant flow of water replenishes the tank and maintains a steady temperature. Sometimes, changes in the function of your water heater can lead to odd noises that shouldn’t be ignored.

Sediment Buildup

One of the most common causes of weird noises in your water heater is the buildup of sediment at the bottom of the tank. This buildup can cause popping or crackling sounds as the water bubbles up through the sediment layer.

Flushing your water heater annually can help prevent sediment buildup.

Expansion & Contraction

If you hear a ticking or tapping sound, it could be due to the expansion and contraction of the metal parts in the water heater as they heat up and cool down. It’s normal and usually nothing to be concerned about.

High Pressure

A whistling or hissing sound could be a sign that the pressure in your water heater is too high. This could be dangerous and should be checked by a professional as soon as possible.

Water Heater Age

Like any appliance, water heaters can start to make strange noises as they get older. If your water heater is over 10 years old and making noises, it might be time to consider replacing it.

Additional Tips

Noises aren’t the only signs that something could be wrong with your water heater.

Whether you’ve already heard some strange sounds or just want to ensure your water heater is in good condition, consider these tips from our plumbers:

  • Keep an eye out for any leaks or puddles around your water heater, as this could indicate a problem that needs immediate attention.
  • Insulate your water heater to prevent heat loss and reduce the strain on its components, which can also help reduce noise levels.
  • Consider investing in a newer model of water heater with advanced features such as a self-cleaning mechanism to prevent sediment buildup.
  • Be proactive about maintaining your water heater to help prevent strange noises and ensure its longevity.
  • Upgrade to a tankless water heater for greater energy efficiency and no tank-related concerns.

Schedule a Professional To Evaluate Your Water Heater

If your water heater is making unusual noises, it’s a sign that something isn’t right. Whether it’s due to sediment buildup, high water pressure, or a faulty heating element, it’s crucial not to ignore these signs.
