Why is my Water Heater making noise?

Three gray water heaters of different sizes are standing side by side, each displaying the A.O. Smith logo and a "Plumbing Today" service logo on the front.
Water Heaters
It’s never a fun time when things go wrong in our home, especially in our plumbing system!
Your water heater is an essential part of your home as it’s how your plumbing system provides hot water, so why is yours making noises?
Why could mine be making noise? 
Sediment Build-Up is a common cause for a “popping” sound that can be heard in water heaters, and this noise often comes from limescale, calcium and other sediments that build up along the side of the tank & burner.
Do you like it when your food is sizzling? I imagine so! However, I don’t think when your water heater is making a similar “sizzling” noise you enjoy it as much.
This noise in your water heater can often be caused by a leak which is NEVER good! The most common leak to cause this noise is where the water is leaking onto the water heater’s burner.
Another High-Pitched Sound that Can’t be pleasant to hear is the screaming, singing, sizzling sound that high water pressure in your unit. This can be a result of when water flow is restricted through a valve.
What about Expansion & Contracting? Think these could have anything to do with your unit making noise? Well… they can, this is when the heater turns off and on the metal parts within the unit can expand & contract which causes a clicking or squeaking sound.
Condensation isn’t just an issue that can appear on you’re A/C Unit, because condensation on your water heater is just as bad, condensation around the burner of your unit can cause a “crackling” or “popping” sound
If your water heater is making any of these noises this doesn’t necessarily mean that your water heater is damaged or needs replacement, but I would keep an eye or an ear out for these sounds becoming worse, louder or more persistent so damage is avoidable.
Plumbing Maintenance is also a good way to keep these noises from becoming issues or repairs in the future, most companies offer a maintenance service or plan. Air and Plumbing Today offers a Annual Service for $89 dollars which entails a full 57 point whole home plumbing inspection, which checks all fixtures, drains & valves. We also flush your water heater & inspect your water softener making sure both units are up to code.
