Why Is My Water Heater Making Noises?

To keep the hot water flowing in your home, it’s crucial to ensure your water heater is kept in good working condition. A good way to keep your unit in check is by keeping an eye out for signs of malfunction, including strange noises. Strange noises, whether humming, clanging, or anything else, often indicate underlying issues with your water heater. Fortunately, there are some steps homeowners can take themselves to correct the issue. In this blog, our expert plumbers at Action Plumbing, Heating, A/C & Electric discuss some common sounds heard from water heaters, DIY problem-solving steps, and when you should call a professional plumber.

Common Water Heater Noises and What They Can Mean

It’s normal for your water heater to make some noise during operation, but it should be minimal. Any loud or frequent noises are an indication that something is wrong. It’s important to familiarize yourself with noises that aren’t standard and could be a cause for concern.

Humming

If you notice a humming sound coming from your unit, it’s likely due to a loose heating element or failed electrical component, which can be a hazard. When you hear humming, it’s best to call a plumber to repair your water heater.

Hissing

Hissing is typically only heard from electric water heaters and is often caused by sediment buildup on the lower heating elements in your tank. When the sediment becomes excessive, it will create a barrier between the heating element and the water, resulting in a hissing sound. To fix this, flushing the tank and removing the sediment should do the trick.

Banging

Banging or knocking sounds often indicate a water hammer issue, which is the high-pressure shockwave that occurs when the water flowing changes directions or abruptly stops. A professional fix is needed for this issue as the forceful pressure can be strong enough to burst a pipe.

Popping

Water heaters may produce a popping sound due to sediment buildup. Steam bubbles can form under the sediment and burst through, making a popping sound. Flushing the system, draining the tank, and removing the sediment is the best way to address this issue.

Running Water

While the sound of running water is normal at points, it can signify a leak or other issue if it persists. Check for leaks or puddles yourself and call a professional for expert leak detection and repair as needed.
