Water Heater Noises Explained
If you've ever heard strange noises coming from your water heater, you may be wondering what's causing them. Water heater noises can be alarming, but they are often the result of normal operation or minor issues that can be easily resolved.
One common cause of water heater noises is sediment buildup. Over time, minerals and other debris can accumulate at the bottom of the tank, which can cause banging or rumbling sounds when the heater is running. Flushing the tank can help remove the sediment and resolve the issue.
Malfunctioning Heating Element
Another potential cause of water heater noises is a malfunctioning heating element. If you hear a hissing or sizzling sound, it may be a sign that the heating element is overheating or failing. This can be a more serious issue that requires the attention of a professional plumber.
A ticking or tapping sound coming from your water heater may be caused by thermal expansion. As water heats up, it expands, which can cause pipes and other components to expand and contract as well, creating a ticking or tapping noise. This is generally not a cause for concern.
Pressure or Temperature Changes
Popping or cracking sounds can sometimes be heard coming from a water heater. This may be the result of changes in temperature or pressure inside the tank, and is usually nothing to worry about.
If you're hearing unusual noises coming from your water heater, it's important to identify the cause and address it promptly.
