Common Causes of Noisy Water Pipes

Water pipes are an essential part of any home plumbing system, but nobody wants to be able to hear theirs. If your water pipes are making loud noises, this is a sure sign that something has gone wrong. To address the noise, it’s important to know what caused it, so our plumbing experts at Meetze Plumbing have put together this guide to common causes of noisy water pipes.

Loose Pipe Straps

Another common cause of noisy water pipes is loose pipe straps or hangers. Over time, the hardware that secures your plumbing pipes to the walls or ceilings may wear down or loosen. When this happens, the pipes can vibrate or rattle as water flows through them, resulting in a clanging or rattling noise.

Corrosion & Aging

As your plumbing system ages, pipes may corrode or deteriorate, leading to various issues, including noise. Corroded or damaged pipes can develop leaks or produce a creaking or groaning sound as water flows through them. If your plumbing system is old, it may be time to consider a comprehensive inspection and potential pipe replacement to address these issues.

Sediment Buildup

Sediment buildup in your water heater can also lead to noisy pipes. As water heaters heat water, sediment from the water supply can settle at the bottom of the tank. This sediment can trap heat, causing the water to boil and create bubbles. When these bubbles rise, they can produce a popping or rumbling sound that travels through your plumbing system.

Hiring a plumber to flush and maintain your water heater can help prevent sediment buildup.

High Water Pressure

High water pressure can put excessive stress on your plumbing system, causing noisy pipes as water rushes through at an unnaturally high speed. If your water pressure exceeds the recommended levels, it can lead to various problems, including leaks, damage to appliances, and noisy pipes.

To address water pressure issues, install a pressure-reducing valve (PRV) if you don’t already have one. A PRV will regulate the water pressure, ensuring it stays within a safe range.

Air Bubbles & Pockets

Sometimes, noisy pipes are simply the result of air trapped within the plumbing system. When air pockets get trapped in the pipes, it can create a gurgling or squealing sound as water flows past the pockets of air. This issue is more common in older plumbing systems and may require a professional plumber to bleed the air from the pipes.

Water Hammer

One of the most frequent culprits behind noisy water pipes is a phenomenon known as water hammer. Water hammer occurs when the flow of water in your plumbing system suddenly stops or changes direction. This abrupt change in water flow creates a shockwave that travels through the pipes, resulting in loud banging or hammering sounds. This can be caused by various factors, such as quickly closing a faucet, toilet valve, or a malfunctioning water pressure regulator.

To address water hammer, a professional plumber can install water hammer arrestors or expansion tanks. These devices can absorb the shockwaves, preventing the noisy reverberations through your plumbing system.
