Have you ever been startled by banging, rattling, or whistling noises coming from your plumbing system?

Why Do Pipes Make Noise?
Your home’s plumbing system is essentially a network of pipes that carry water to and from faucets, toilets, appliances, and drains. When water flows through pipes, it can cause vibrations, pressure changes, or even mechanical movement of the pipes themselves.
Certain sounds are completely normal, while others indicate problems like water hammer, air in the pipes, or loose fittings.
Common Plumbing Noises Explained
1. Banging or Hammering (Water Hammer)
What it sounds like: A loud banging or knocking noise, often when you turn off a faucet or valve suddenly.
Why it happens: When water flowing through the pipes stops abruptly, it causes a shockwave or “hammer” inside the pipes. The sudden pressure spike can shake and rattle the pipes against walls or framing.
Is it normal? Occasional water hammer can be normal, but persistent or loud banging should be addressed. Over time, water hammer can damage your plumbing and appliances.
2. Whistling or Squealing
What it sounds like: A high-pitched whistle or squeal coming from faucets, valves, or pipes.
Why it happens: This noise usually occurs when water flows through a partially closed valve or a narrowed pipe, causing turbulence. It can also be a sign of worn washers or cartridges in faucets.
Is it normal? Minor whistling isn’t unusual, but if it’s loud or persistent, it could indicate a failing valve or pipe restriction.
3. Rattling
What it sounds like: A rattling or vibrating noise, often when water is running or valves are open.
Why it happens: Pipes may be loose and vibrating against walls, floors, or studs. This often occurs in older homes or if the plumbing wasn’t secured properly during installation.
Is it normal? A little vibration can be normal, but continuous rattling suggests loose pipes that should be fastened.
4. Gurgling
What it sounds like: A bubbling or gurgling noise coming from drains or toilets.
Why it happens: Gurgling usually indicates a partial blockage or venting problem in the drain system. Air trapped in the pipes causes water to bubble and make noise as it drains.
Is it normal? No, gurgling sounds often signal clogged drains or vent pipe issues and should be investigated promptly.
5. Hissing
What it sounds like: A soft hissing or rushing sound near plumbing fixtures or water heaters.
Why it happens: This can be caused by water leaking from a small crack, a failing valve, or pressure relief valves releasing steam or water.
Is it normal? Not usually. Hissing sounds should be inspected to rule out leaks or appliance malfunctions.
Causes of Noisy Pipes in Coastal Homes
Homes in Murrells Inlet, Myrtle Beach, and surrounding Grand Strand areas face unique plumbing challenges:
Older pipe materials: Many homes have galvanized steel, cast iron, or polybutylene pipes prone to corrosion and noise.
Salt air corrosion: Coastal humidity and salt can degrade pipe fittings, causing leaks and rattling.
Water pressure fluctuations: Variable municipal water pressure can cause banging or hammering sounds.
Loose plumbing supports: Expansion and contraction from temperature changes cause pipes to move if not secured well.
How to Fix and Prevent Noisy Pipes
1. Install Water Hammer Arrestors
If banging occurs when faucets or valves close, a water hammer arrestor can absorb pressure shocks and prevent pipe knocking.
2. Check and Adjust Water Pressure
Excessively high water pressure often causes pipe noise and damage. Installing a pressure regulator valve helps maintain safe, steady pressure levels.
3. Secure Loose Pipes
Pipes should be firmly fastened with clamps or brackets to prevent rattling and vibration. A plumber can add supports or adjust existing ones.
4. Replace Worn Washers and Valves
Whistling and squealing often result from failing washers or cartridges. Replacing these parts in faucets and valves will restore quiet operation.
5. Clear Drain Blockages and Vents
Gurgling sounds require drain cleaning or vent pipe inspections. Blocked vents can cause drainage issues and sewer odors.
6. Inspect for Leaks
Hissing sounds should prompt a thorough leak inspection. Leaks not only make noise but waste water and can cause costly damage.
