Strange Plumbing Noises: What They Mean and When to Call a Plumber

Has your plumbing system ever made any unusual noise that alarmed you? Perhaps you heard a loud bang in the middle of the night, or perhaps you heard pipes rattling or something gurgling out of the drain. These sounds typically indicate a plumbing issue.

This article will discuss some of the most typical odd plumbing noises, what they mean, and when you should call a plumber in North Sydney.

Common Plumbing Noises and Their Meanings

1. Banging Pipes (Water Hammer)

1. If you hear a banging noise when you shut off the water, you may be dealing with a “water hammer.” This happens when the water flow stops suddenly, causing a pressure wave to rush back through the pipes, which creates a banging or thumping sound.

Why Water Hammer Is a Problem
The sound of the water striking is more than just irritating. Your pipes and joints may experience stress from the pressure wave, which might lead to leaks or loose parts. Over time, pipes may burst or crack due to this type of continuous pressure, which might cause serious water damage. If the leak is not fixed, water may seep into the floors and walls, causing structural damage and the growth of mould.

You may need to add slow-shutting valves, modify your water pressure, or install an arrestor in order to deal with the water hammer. Older plumbing systems may occasionally need a more extensive fix.

2. Gurgling Drains

2. A gurgling sound in your drains usually indicates trapped air in the plumbing system, which often points to a blockage. As water flows past a blockage, it forces air through the pipes, causing the gurgling noise.

Why Gurgling Drains Matter
Over time, the blockage creating the gurgling sound may get worse, slowing down water flow and sometimes resulting in full blocked drain. Serious hygiene problems might arise from sewage or water backing up into sinks, bathtubs, and other fixtures. Insects and germs thrive in standing water, and sewage backups can expose you to dangerous microbes.

To successfully clear deep or obstinate clogs, though, a plumber’s snake or hydro-jetting may be needed for more difficult obstructions. Gurgling in the drain should be taken carefully as it typically indicates an impending issue.

3. Whistling Pipes

3. A whistling or squealing noise in your pipes often indicates an issue with a valve or washer. When water flows through a partially blocked area, it can create turbulence, resulting in a whistling sound.

Diagnosing Whistling Sounds
If the noise is coming from only one tap, it’s probably the result of a worn-out valve seat or washer. But if there’s whistling throughout the entire home, there could be a problem with the pressure-reducing valve. Elevated water pressure can harm fixtures and pipelines, leading to leaks or malfunctions and increasing water costs.

The problem could be resolved by changing the water pressure or replacing a damaged washer. To avoid more harm, it is imperative that you speak with an expert if the noise continues even after these changes have been made.

4. Rattling Pipes

4. Rattling or vibrating sounds suggest your pipes aren’t securely fastened. Loose pipes can knock against walls, other pipes, or structures when water flows through them, leading to a rattling noise.

Why Rattling Pipes Are a Concern

Rattling pipes may seem like a minor issue, but the constant movement can cause wear and tear, particularly at the joints. Over time, this can lead to leaks or even full pipe failure. The vibration could also be caused by other underlying problems, such as high water pressure or water hammer, which need to be addressed.

Fixing rattling pipes may require adding more pipe straps or replacing worn-out ones. In some cases, it may be necessary to access walls or floors to properly secure or reposition pipes.

When to Call a Plumber

In the event that the noise goes on for days, it is recommended to contact a plumber in North Sydney who can identify the issue and safely and effectively resolve it.
