Water Heater Repair 101: Why Is My Water Heater Making Noise?

You’re cozied up on the couch, enjoying a quiet evening at home, when suddenly, an unexpected orchestra of noises starts emanating from your water heater. If you find yourself in this situation in your Indianapolis home, you’re not alone. Water heater issues can be a common household concern, and addressing them promptly is crucial. Here’s a bit of insight from the professionals at Mister Water Heater. Let’s explore the various sounds your water heater might make and what type of water heater repair it may need.

Knock, Knock, Who's There?

The knocking noise from your water heater is a common culprit when you have hard water. As water flows through your heater, it leaves behind mineral deposits at the bottom of the tank, gradually accumulating over time. These deposits, also known as scale, can wreak havoc on your system.

Hard water scale causes hot air bubbles from the heating unit to disturb the sediment, making it clank against the walls of your water heater. This sound is not just an annoyance; it can damage your water heater over time. The best way to address this is by having your water heater serviced every 1-2 years. Regular maintenance can eliminate mineral deposits and ensure your water heater operates smoothly.

Humming Sound

When your water heater hums, it's likely not singing a cheerful tune. This sound could be a warning sign that a component of your water heater is going bad. If you have an electric water heater, the culprit might be the heating element. For gas water heaters, it could be the gas burner assembly or another part of the unit.

If this is your water heater issue, don't worry. We've got you covered. We can replace these parts or install a new, energy-efficient water heater to ensure your home stays comfortable and your energy bills stay reasonable.

Crackle, Crackle, Pop

On occasion, these are the sounds of electricity-powered water heaters. A little crackling now and then is normal. However, persistent crackling might indicate an issue, possibly an obstruction in the heating element.

If your water heater is powered by gas, moisture build-up may be the culprit behind these sounds. It's essential to have a technician check for water pooling around your unit to prevent any electrical mishaps. Even non-electric water heaters still require electricity to run, so preventing water from interfering with electrical components is crucial.

Screeching Sound

That high-pitched screech or whistle coming from your water heater is another issue that can't be ignored. The cause could be loose valves letting air escape your tank. We can come to the rescue by checking your pressure-releasing valves, temperature valves, and inlet/outlet valves to ensure they are properly adjusted. Every water heater has a manufacturer's manual that can show the precise locations of these components on your unit.

Your water heater doesn't have to be a noisy neighbor. Whether you need water heater repair or a complete water heater replacement for your Indianapolis area home, Mister Water Heater is here to help. Contact us at (833) 270-8502 or request service online. The solution is just a call away.
