Feeling anxious, frustrated, or confused about annoying crackling noises coming from your water heater? Don’t worry, these noises usually mean something needs a little attention. Lowe’s estimates, “that most water heaters have a good long life, lasting around 8-12 years”, especially if they get some regular maintenance. How long your home’s gas or electric water heater lasts depends on how much it gets used and if a professional takes a look at it every year. It is time for a checkup when your water heater makes crackling noises! We know all the strange water heater sounds, what they mean, and how to get yours working quietly again.
What Do Those Water Heater Noises Mean?
If you hear popping or crackling noises coming from your water heater, chances are there’s a buildup of mineral deposits in the tank – kind of like tiny rocks at the bottom. Water gets trapped under those deposits, and when it heats up, it makes those popping noises. This isn’t just annoying, it can also limit your hot water and even damage your water heater over time. The best way to fix this is a good flush of the tank, something a professional plumber can do for you. Don’t ignore that popping, if left alone, it could lead to bigger and more expensive problems down the road.
What Do Screeching Sounds Indicate?
Screeching noises from your water heater are a cause for concern. A high-pitched screech could mean a few things, including problems with the inlet control valve. This valve regulates water flowing into your tank, and if it gets partially stuck closed, it can cause high pressure and annoying noises. Other times, the issue might be with your pressure relief valve or even your home’s water supply. Whatever the cause, it’s best to have a plumber take a look as high pressure could damage your water heater or even be dangerous.
Does Condensation Produce Crackling Noises?
If your water heater is making crackling or sizzling sounds, and you notice some water around the base, it might be dealing with excess condensation. This happens especially with gas water heaters, where the burner flame can cause water droplets to form on the outside of the tank. When those water droplets hit the hot burner, they sizzle and pop – causing those strange noises. While the sound itself might not be dangerous, excess condensation can signal other problems, like leaks or improper venting, that need to be addressed by a plumber.
How About Humming Sounds?
Bob Villa suggests, “A low humming sound from your electric water heater often points to issues with the heating element”. These elements are responsible for actually heating your water, and over time they can get coated with mineral deposits. This makes it harder for them to work, and that can cause a vibrating or humming noise. Sometimes, a simple tightening of the heating element can fix the hum. Other times, the element may be failing and need replacement. A plumber can diagnose the exact issue and provide the right fix.
