As Halloween approaches many of us are ready for some eerie fun with costumes, decorations, and spooky stories. However, when it comes to your home’s water heater, strange and spooky sounds are no laughing matter.

Your water heater should run smoothly and quietly. If you start hearing eerie noises from your water heater it could mean that you need to invest in water heater repairs in Chesterfield, MO. Let’s take a look at three spooky sounds your water heater shouldn’t make and what they might indicate if you hear them.

Strange Hissing Noises

If you notice a hissing or sizzling sound coming from your water heater, it can be unsettling. This sound can be likened to the creepy whispers in a ghost story. There’s a practical explanation for this eerie noise though. It could be caused by a water leak.

Leaking water can be a sign of a failing water heater tank. The hissing sound could also be due to a buildup of sediment at the bottom of the tank. This may cause water to boil and create steam.

Both issues can lead to more severe problems if left unchecked. This includes water damage and potential safety hazards. In order to correct the issue, turn off the power supply to the water heater and shut off the water source. Contact a professional plumber to inspect and repair the issue and make sure to have your water heater flushed regularly to prevent sediment buildup.

Unusual Ghostly Groans and Popping Sounds

Imagine hearing mysterious groans and pops coming from your water heater, like the creaking sounds in a haunted house. This unsettling noise can be attributed to the expansion and contraction of the water heater tank.

Over time, as the tank heats and cools, it expands and contracts, causing the metal to make these noises. Sediment buildup can amplify these sounds, making them even more noticeable. Regular maintenance like flushing the tank to remove sediment can help reduce these noises. If the sounds persist or worsen, it’s a good idea to have a professional plumber inspect your water heater for any potential issues.

Phantom Knocking and Banging

A loud knocking or banging sound echoing from your water heater can be quite alarming. It can be reminiscent of ghostly footsteps in an empty hallway. This sound is often referred to as a water hammer. This occurs when fast-moving water suddenly stops or changes direction.

This causes a shockwave that can lead to banging or knocking sounds. This issue can damage pipes and fittings over time. Consider installing water hammer arrestors or air chambers in your plumbing system to absorb the shockwaves and eliminate the noise.

While Halloween is the perfect time for spooky sounds and ghostly tales, you don’t want your water heater to join in the festivities. If you hear any of these eerie sounds emanating from your water heater, don’t be spooked. Instead…
