Is Your Water Heater Making Noise? What It Means

Unusual noises coming from your water heater usually indicate a mechanical problem or sediment buildup. Addressing these noises early can help prevent breakdowns.

Popping or Cracking Sounds

This usually indicates sediment at the bottom of the tank. As water becomes trapped beneath the debris, it overheats and creates popping sounds.

Hissing or Sizzling

This can indicate a leak that is dripping onto the burner assembly or electrical components.

Banging Noises

Pressure fluctuations or loose pipes can cause banging during heating cycles.

If these noises match the symptoms described in our short hot water guide or our article on winter heater problems, it may be time for service.
