Why Are My Pipes Making Noises?

Are your home’s pipes banging, rattling, or gurgling when you turn the water on or off? Your plumbing system is a complex maze of pipes, valves, and drains, and one of the first signs something’s wrong is when the pipes start making strange or loud noises. Here’s a look at what might be causing all the commotion.

Banging Sounds

If you hear banging from the pipes in your home, the likely culprits are high water pressure or water flow problems. If it sounds like someone’s whacking the pipes with a gavel every time you run the water, it could be a condition known as water hammer, which happens when a valve closes suddenly.

Whatever the cause, when left unaddressed, these issues can lead to leaks and joint damage. Installing water hammer arrestors or reducing your home’s water pressure can help solve the problem.

Rattling Sounds

It takes a lot of pressure to move water through your pipes, so they’re bound to move a little when the water’s turned on. Rattling noises typically indicate you need to better secure the pipes by installing or replacing fasteners.

Squeaks & Squeals

Squeals and squeaks confined to a single fixture often happen when small plumbing components like washers or aerators become loose, damaged, or dirty. Repairing or replacing the defective part should solve the noise.

On the other hand, if the squealing sound can be heard throughout the house, it could be a water pressure issue due to a clog or buildup inside the pipes. It’s best to have a professional plumber diagnose the problem to avoid further damage.

Humming Noises

When the water pressure gets too high for your home’s plumbing system capacity, the pipes can start to vibrate and hum when the water is running. Properties with well water are at a higher risk for vibrating pipes, though the condition can happen in any home.

High-Pitched Whining

Plumbing hardware components such as washers, nuts, and bolts often loosen or wear out, creating a high-pitched whining noise when they do. Sometimes all it takes to fix the problem is having a plumber replace the hardware.

Whistling Pipes & Taps

You might hear a whistling sound when the water supply is forced past a water pipe obstruction, or if the pipe narrows. Common causes are dirt and corroded metal that get into your home’s plumbing through the water main and become trapped.

Simple blockages can usually be cleared, but if there’s extensive mineral buildup, you might need to replace some piping. If a whistling sound comes from one of your faucets, you might need to take the tap apart and reposition or replace the washer.

Hissing Toilets

A hissing noise after a toilet’s flushed and the tank is refilling is usually due to a problem with the ballcock assembly. If the hissing continues after the tank is full, it might mean water is escaping down the overflow pipe. Adjusting the ballcock so the water stops at a slightly lower level can usually solve the problem.
