Don't Run From Those Scary Water Heater Sounds!

Hot Water Heater Sounds: Beware

Scary sounds coming from a water heater can be quite scary. Is the water heater haunted? It could be, which is a disturbing prospect. However, a more worrisome thought is that the water heater needs repair. Popping, screeching, and crackling are common sounds that water heaters make when something is malfunctioning.

Fortunately, qualified plumbing professionals can tackle even the most complex gas and electric water heater problems and can quiet them down right away.

Popping Sounds Explained

What’s that loud popping sound all about? Mineral deposits in water cause sediment to collect at the bottom of water heaters over time. When the water is heated, the sediment whirls, bubbles, and pops, explaining the puzzling sound. The accumulation of sediment is inevitable, particularly in homes with hard water. That said, the amount of sediment needs to be controlled. This is accomplished by having the water heater routinely flushed out by a plumbing professional. 

Too much sediment causes a multitude of problems for the water heater. It can cause accidental overheating, which often leads to damaging leaks. Too much sediment also causes a water heater to operate less efficiently, wasting energy. Regular flushing out of a water heater is an absolute must, and hearing that popping sound may mean it’s time to schedule an appointment.

Why the Water Heater Is Screeching

It’s never a good sign when the appliances start to scream. Luckily, there is a perfectly reasonable explanation for a screeching water heater. When water flow becomes restricted, it causes a sharp, high-pitched sound to emanate from the pipes. Water restriction can usually be corrected by having a plumbing professional adjust all the valves to ensure that they are properly open. Another possibility is that the pipes are corroded, have a leak, or require partial replacement. There are several ways that water can become restricted, causing the screeching noise. A plumber will quickly put an end to the noise with some swift repairs.

Crackling Hot Water Heaters

Now the water heater is crackling? What on Earth? The good news is that crackling is most likely due to condensation hitting the burner, which is completely normal. Condensation causes water vapor to build up around the burner, resulting in a sizzling, popping sound. Smaller water heaters tend to produce a lot of condensation, and it is usually most noticeable when the outside temperature drops. However, if the amount of condensation that builds up on the burner is excessive, have a professional inspect your water heater because it could be a sign of failure.
