Water heaters are one of the hardest-working appliances in your home. So when they start making strange noises — banging, popping, hissing, or rumbling — it’s usually a sign that something inside the unit needs attention.

If you’re a homeowner in Stuart, FL and you’ve noticed unfamiliar sounds coming from your water heater, Two Anchors Plumbing is here to help you understand what’s going on and when it’s time to call a professional.

Common Water Heater Noises & What Causes Them

🔊 1. Popping or Cracking Sounds

This is the most common noise.

Cause:
Sediment buildup at the bottom of the tank.
Florida’s hard water leaves behind mineral deposits. When water gets trapped beneath these layers, it superheats and pops through.

Why it matters:
Sediment forces your heater to work harder, raising energy bills and shortening the unit’s lifespan.

🔊 2. Rumbling or Booming

If your water heater sounds like it’s boiling or shaking…

Cause:
Heavy sediment buildup or overheating due to restricted water flow.

Warning:
This can lead to tank damage or even early tank failure if ignored.

🔊 3. Hissing or Sizzling

This typically happens on electric water heaters.

Cause:
Burning or overheating elements due to mineral deposits or water dripping onto hot parts.

You may notice:

• Inconsistent water temperatures

• Higher electric bills

• Slow heating

🔊 4. Tapping or Knocking

This often happens in homes with water hammer issues — when fast-moving water suddenly stops.

Cause:
High water pressure or improperly secured plumbing pipes.

Left untreated:
It can cause pipe damage or leaks.
