Is Your Water Heater Making Scary Noises? What These 5 Sounds Mean

It can be unsettling if your water heater makes strange noises. But what do those scary sounds mean? We are going to explain the familiar sounds that homeowners in Minneapolis-St. Paul may hear from their water heaters, what causes them and when action is needed. Consult the experts at Paul Bunyan Plumbing & Drains for any persisting issues.

Popping or Cracking Noises

When you hear your water heater producing popping or cracking noises, it might sound like something out of a horror movie, but fear not! These sounds have a logical explanation:

  • Cause: The water heater’s tank’s metal naturally expands as it heats up and contracts as it cools down.
  • Action Needed: No action is required for this noise; it’s just the result of the regular heating and cooling process.
  • Humming

Is there a mysterious hum resonating from your water heater? This could be a sign of sediment buildup:

  • Cause: Sediment accumulates at the bottom of the tank, leading to friction between the sediment and the moving parts of the heater.
  • Action: To address this, it’s recommended to drain and flush the water heater to eliminate sediment. If unsure, reach out to Paul Bunyan for professional assistance.
  • Banging or Hammering

Are you startled by loud banging or hammering sounds from your water heater? Don’t worry; it’s not a poltergeist, but it’s still a concern:

  • Cause: Water pressure irregularities or loose pipes can lead to these unsettling noises.
  • Action: Inspect your pipes for leaks or damage and consider installing a water pressure regulator to stabilize pressure. If the problem persists, contact Paul Bunyan for expert advice.
  • Screeching or Grinding

Does your water heater emit screeching or grinding sounds? It’s not a horror movie sound effect; it’s likely sediment-related:

  • Cause: Metal rods within the tank might be rubbing together due to sediment buildup.
  • Action: A thorough draining and flushing of the water heater can often resolve this issue. If the noise continues, it could be a sign that your water heater needs replacement, and Paul Bunyan can assist with that.
  • Leaking Water

Discovering water pooling around your water heater? It’s not a ghostly apparition, but it does require your attention:

  • Cause: Leaks might stem from problems with the pressure valve, corrosion, or loose fittings.
  • Action: Depending on the cause, you might need to repair the valve, patch any leaks, or replace fittings and gaskets. If you’re unsure, the plumbing experts at Paul Bunyan can provide the necessary repairs.
