Understanding the potential types of water heater sounds and the underlying causes is the first step toward learning why your water heater is making noise and solving this mystery—ensuring the longevity and efficiency of your appliance.

Understanding the Noise

Water heaters are generally quiet appliances but can start making various noises over time. Identifying the type of noise you hear is crucial in diagnosing the issue:
