Why Is My Water Heater Making So Much Noise?

Water heater making sounds that are driving you crazy? We know the feeling. Not only can loud banging or knocking sounds cause you to wake up abruptly during the middle of the night, they can simply disturb the peace and quiet at any time of the day. Luckily, not all of the sounds your water heater makes indicate there is a serious problem. Here are a few common noises your water heater might make and what those sounds often mean:

Popping, Tapping or Knocking Sounds

These are the most common noises a water heater makes and luckily, it’s usually a simple fix. These noises indicate there is a buildup of sediment, or mineral deposits in the tank and it needs to be flushed out. Even if you’re not hearing these noises just yet, we recommend flushing your water heater once a year to avoid more troublesome problems down the road.

Humming or Buzzing

If you have an electric water heater and notice a humming or buzzing sound, it usually means water is flowing around the heating element. When this happens, it can cause vibrations which create the noises you’re hearing. Most of the time, a slight tightening of the element will fix the problem and get rid of the noise.

Screeching

This is usually one of the more alarming sounds your water heater can make and for good reason. Screeching sounds are never good and usually indicate that water flow is restricted or that there’s a serious problem with a part or component. While it may just be a partially closed valve that needs to be adjusted, these noises shouldn’t be taken lightly. It’s always best to call in a professional right away.
