Popping Noise

Cause: If your water heater is making a popping noise, there is most likely a large buildup of mineral deposits or sediment collecting at the bottom of your water tank.

Sizzling Noise

Fix: If your water heater is experiencing a leak, it’s time to call a professional ASAP! Your system is most likely coming to the end of its lifespan and will need to be replaced.

Screeching Noise

Cause: If the water heater is making a screeching noise, this is often a sign that you are experiencing a water flow issue, typically caused by the control valve.

Fix: Luckily, this is an easy fix. Take a look at your inlet control valve and make sure it is fully open.

Humming Noise

Cause: Humming sounds from your water heater often indicate that components within the system are loose.

Fix: While the fix is simple, it needs to be caught early so don’t ignore the noise! With the help of a professional, the system will be turned off, inspected, and loose elements will be tightened to stop the source of the vibrations.

If you hear any strange sounds coming from your system it’s better to be safe than sorry! Don’t cover your ears and assume the problem will go away on its own, call a professional!
