3 Water Heater Noises That May Indicate a Problem

12/21/2021 (Permalink)

The water heater in your Champaign/Urbana home can be a vital piece of equipment when it comes to providing your family with hot water for cleaning and bathing. Despite its importance, you may not give it much thought unless it acts up. The sounds a unit makes can be an indication of a problem, and there are several different noises you can listen for if you suspect a malfunction.

1. Screaming

This sound can be startling, especially if it happens suddenly. However, there is usually no cause to be alarmed. A screaming water heating unit may have loose valves that need to be adjusted or tightened. You may be able to chase down the noise by listening closely when someone turns on the water in the kitchen or bathroom.

2. Banging

Noisy pipes can be common in older homes, and banging sounds that emit from your water heater usually occur if the unit is not bolted down properly or if pipes move or jerk suddenly when the water in your home is turned on or off. Over time, this movement may cause damage to the pipes or the tank itself. You can prevent these problems by bolting down the pipes and the tank or by updating your home's plumbing.

3. Crackling or Popping

If you hear crackling, rumbling or popping as your water heats up, this may be a sign that sediment has collected inside your unit. This can be especially true of older units or those that have never been serviced. Having your heater inspected and cleaned can improve its efficiency and ensure that small problems do not get any worse.

If your water heater is noisier than usual, it may be trying to tell you something. Having the unit inspected and maintained can keep it running like new and quiet any troublesome noises.
