Why Is My Water Heater Making Strange Noises?

A water heater is an essential appliance in any home, providing hot water for bathing, cooking, and cleaning. But what happens when your water heater starts making unusual noises? If you've noticed banging, popping, or rumbling sounds coming from your unit, it could be a sign of an underlying issue that needs attention. Ignoring these noises can lead to bigger problems down the line, such as inefficiency, higher energy costs, or even a complete system failure. Fortunately, the experts at Parson Plumbing and Drains are here to help! Let’s explore some common reasons for water heater issues in Columbus and what you can do to fix them.

Sediment Buildup

One of the most common causes of strange noises in a water heater is sediment buildup. Over time, minerals from hard water settle at the bottom of the tank, creating a layer of sediment. When the burner heats the water, the trapped water beneath the sediment turns into steam, causing popping or rumbling sounds. This not only makes your water heater noisy but also reduces its efficiency, causing it to work harder and increasing your energy bills.

Flushing the tank regularly can help remove sediment buildup and improve efficiency. However, if your unit hasn’t been maintained in a while, a professional flush may be necessary to prevent further damage. The skilled technicians at Parson Plumbing and Drains can perform a thorough cleaning, ensuring your water heater operates at peak performance and extends its lifespan.

Expansion and Contraction of Metal

As water is heated, the metal components of the water heater expand and contract. This can create clicking or ticking sounds, which are typically harmless but may indicate that parts are wearing out over time. If these sounds become more frequent, they could signal a potential problem that requires professional attention.

If you’re concerned about the noises coming from your water heater, don’t hesitate to contact Parson Plumbing and Drains. We can inspect your system, identify any potential issues, and make the necessary adjustments to keep your water heater running smoothly.

Accumulation of Scale on Heating Elements

For homes with electric water heaters, a buildup of scale on the heating elements can cause hissing or crackling sounds. This occurs when minerals from hard water collect on the elements and create an insulating layer, reducing efficiency and increasing energy usage. Over time, this buildup can lead to overheating and even premature failure of the heating elements.

Periodically inspecting and cleaning the heating elements can help maintain efficiency and prevent costly repairs. If your water heater is struggling to produce hot water or making persistent noises, Parson Plumbing and Drains can inspect your unit, remove scale buildup, and replace faulty elements if needed.

Water Pressure Issues

If your water heater is making a high-pitched whining noise, it may be due to excessive water pressure or a failing pressure relief valve. High pressure can be dangerous and may lead to leaks or even system failure. Keeping your water pressure at a safe level is crucial for the longevity of your plumbing system.

Check your home’s water pressure and ensure it is within the recommended range (40-60 psi). If the pressure relief valve is faulty, replacing it is crucial for safety. Parson Plumbing and Drains specializes in diagnosing and repairing water heater pressure issues, ensuring your system remains safe and functional.

Loose or Faulty Components

Sometimes, unusual noises can be caused by loose parts within the water heater. Vibrating or knocking sounds may indicate that certain components, such as the heating element or pipes, are not securely fastened. Over time, loose parts can lead to more significant damage if not addressed promptly.

A plumber can tighten any loose components and ensure everything is properly secured to prevent further issues. Parson Plumbing and Drains can perform a full inspection, tightening loose parts and making any necessary repairs to restore your water heater’s optimal performance.

When to Call a Professional

If your water heater is making persistent or unusually loud noises, it’s best to consult a professional. Ignoring these sounds could lead to bigger problems, such as decreased efficiency, higher energy bills, or even a complete system breakdown.
