Water Heater Noise: What YOU Need to Know

Water heater noise

Is your water heater making noise? Then you’ve come to the right place. An annoyance and a sign of possible damage, water heater noise demands your attention.

Since Benjamin Franklin Plumbing are your local water heater experts, we can explain why your water heater is making noise, what that means, and what you can do about it.

  • A popping or a rumbling noise is the most common sound that water heaters make. Sediment from hard water causes the telltale sound.
  • Although the sound itself is not harmful, it is indicative that sediment is present in your system, potentially causing serious damage in the future.
  • You have options to prevent water heater noise. A professional sediment flush is the first step. If enough damage has been done, you may need to replace your water heater entirely.

Read on to learn the facts about water heater noise.

Water Heater Noise

From your shower or from your sink, hot water on demand is an expectation. For most homeowners, your showers turning cold is the only reason to pay attention to your hot water heater. However, if you hear a popping or rumbling sound coming from your hot water heater, you should pay attention!

If you’ve ever heard this distinct noise, you know exactly what we’re talking about. If you haven’t, imagine the sound of a percolator coffee pot turned up to 11!

The Cause: Sediment in the Water

Hard water, or the presence of hard minerals in the water, is an issue for the majority of the country.

As the hard water evaporates inside your heater tank, it leaves hard minerals behind. Those minerals linger in your water heater, making the water heater noise and eventually causing damage.

The distinct popping water heater noise is caused by the minerals forming a layer on the surface of the water heater. The popping sound is caused by the pockets of air in the sediment layer boiling along with the water in your hot water heater tank.

Hard Water Damage

While the water heater noise isn’t inherently harmful, it is a sure sign of sediment in your water. Sediment in your water heater, however, IS harmful.

Firstly, sediment in your hot water heater keeps your hot water heater from running effectively, meaning you and your family enjoy less hot water for your morning showers.

Additionally, that hard water actually DESTROYS your expensive hot water heater from the inside out.

Hard water sediment damages hot water heaters in one of two ways:

  1. The sediment damages the heating element, eventually breaking your entire water heater.
  2. The sediment destroys the water heater tank, spilling gallons of water across the floor.

The Solutions

When it comes to combating water heater noise and preventing hard water damage to your heater, you have three solutions.

  1. Schedule a water heater flush — our plumbing professionals will empty all of the sediment from your water heater.
