Why Is Your Water Heater Making Noise? Causes & Fixes

Unusual noises coming from your water heater such as popping, rumbling, banging, or hissing are often early warning signs that something isn’t working as it should. While some sounds may seem harmless at first, persistent noise can indicate underlying issues that reduce efficiency, shorten the lifespan of your system, and lead to costly repairs if ignored. Prospect helps homeowners quickly identify the cause of water heater noise and restore quiet, reliable performance.

Common Causes of Noisy Water Heaters

Several issues can cause a water heater to produce unwanted sounds, especially as systems age or go without routine maintenance:

• Sediment Buildup at the Bottom of the Tank

Minerals in hard water settle at the bottom of the tank over time. When heated, this sediment traps water underneath, causing popping or rumbling noises and forcing the system to work harder.

• Expansion and Contraction of Metal Components

As the tank heats and cools, metal parts naturally expand and contract. Excessive noise may indicate stress on internal components or loose fittings.

• Malfunctioning Heating Elements

Worn or damaged heating elements can vibrate or overheat, leading to buzzing or humming sounds and inconsistent water temperatures.

• Loose Pipes or Valves

Water flow through unsecured pipes or faulty valves can create knocking or rattling noises throughout the plumbing system.
