Noisy Pipes in Your Perth Home? Here’s What Those Sounds Mean

I’ve been listening to Perth’s plumbing systems for years now and I’ve heard almost every sound and creek a pipe can make.

At Plumb It Right, we’ve helped countless Perth homeowners figure out why their pipes are singing, banging, or whistling and what we can do to solve their problems and restore peace and quiet to their beautiful homes.

Understanding Perth’s Unique Plumbing Challenges

Before we dive into specific noises, it’s important to understand how Perth’s environment affects our plumbing. According to the Bureau of Meteorology, Perth’s temperature variations can be quite extreme, especially in areas further from the coast.

I’ve noticed some of these local factors can contribute to a  noisy pipe:

• Some coastal salt exposure affecting your metal pipes
• With sandy soil the movement can impact your underground pipes, sometimes small rocks can rub on the pipe over years and cause a hole.
• Seasonal temperature swings causing expansion and contraction of everything.
• High water pressure zones in the hillside suburbs.
• Hard water running in certain Perth regions.

Why Your Pipes Make Noise (And When to Worry):

Let me start with something I tell all my clients, your home’s plumbing system shouldn’t be a sound effects studio. While some occasional noises are normal, others can signal problems that need attention.

According to the Standards Australia guidelines, certain plumbing noises indicate issues that don’t meet Australian plumbing standards. Let’s break down what these different sounds mean.

Different Pipe Materials, Different Sounds

In my decades of experience across Perth, I’ve worked with various pipe materials. Each has its own “voice”:

Copper Pipes:

• Tend to make louder expansion noises.
• More prone to water hammer.
• Can create a “ticking” sound during temperature changes.

PVC Pipes:

• Generally quieter.
• Can make crackling sounds when hot water flows.
• Might produce echoing sounds when not properly secured.

PEX Pipes:

• Naturally quieter due to flexibility.
• Less prone to water hammer.
• Can make subtle stretching sounds.

Banging and Hammering Sounds:

Just last month, I visited a home in the Perth metro area where the pipes were making such loud banging noises, the homeowner thought someone was hammering on their walls. This common issue, known as water hammering, happens when water flow suddenly stops or changes direction.

Common causes I’ve found include:

• Loose pipes striking against wall framing.
• High water pressure (above the WA recommended levels)
• Worn valve washers.
• Missing or faulty air chambers.
• Rapid valve closure in washing machines or dishwashers.

How I Fix It:

1. First, I check the water pressure.
2. Install water hammer arrestors if needed.
3. Secure any loose pipes.
4. Replace worn components.
5. Adjust automatic valves on appliances.

Whistling or Squealing:

A whistling sound usually means water’s being forced through a tight space.  When helping a client in Lancelin whose taps started whistling every time they turned them on, we discovered a worn washer that was barely there.

Common causes:

• Worn tap washers.
• Loose internal parts.
• Restricted water flow.
• High water pressure.
• Debris in the water line.
• Worn valve stems.

Based on my experience, this often needs:

• Washer replacement.
• Valve cleaning or replacement.
• Pressure adjustment.
• Flow restrictor inspection.
• Complete valve rebuild in older systems.

Gurgling Drains:

The Department of Health WA notes that gurgling sounds can indicate drainage problems that might lead to health issues. I’ve seen this countless times in Perth homes, especially in older properties.

What causes gurgling:

• Blocked vents.
• Partial drain blockages.
• Incorrect pipe gradients.
• Venting issues.
• Sewer line problems.
• Air gaps in the system.

My Approach:

1. CCTV inspection to locate the exact problem.
2. Clear any blockages.
3. Check and repair vent stacks.
4. Adjust pipe gradients if necessary.
5. Hydro-jet cleaning when needed.
6. Install additional vents if required.

Common DIY Mistakes That Make Pipe Noise Worse:

Over my 38 years as a plumber in Perth, I’ve seen plenty of well-intentioned DIY attempts that ended up causing more harm than good. Let me share some real situations I’ve encountered and how to avoid them.

Mistake 1: Aggressive Pipe Banging

Just last week, I visited a home where the owner tried to stop a banging pipe by hitting it with a rubber mallet. As I explained to them, this can actually, loosen existing pipe supports and create new weak points by damaging the pipes joints making the noise problem worse.

Mistake 2: Wrong Pipe Insulation

I’ve lost count of how many times I’ve seen people wrap their pipes in standard home insulation. One client in Perth’s northern suburbs used old beach towels! Here’s why this doesn’t work:

• Regular insulation isn’t designed for pipes.
• It can trap moisture and cause corrosion.
• Some materials can actually amplify noise.
• Incorrect materials can be a fire hazard near hot water pipes.

Mistake 3: Over-Tightening Fixtures

The number one mistake I see is people thinking “tighter is better.” In fact, according to the Plumbers Licensing Board, over-tightening is a common cause of fixture failure. This can:

• Crack pipe fittings.
• Strip threads.
• Damage washers.
• Create new noises.

Mistake 4: Ignoring Pressure Issues

Many homeowners try to fix pipe noise without checking water pressure. A client learned this the hard way after installing new tap washers that didn’t solve their whistling pipes. The real issue was high water pressure.

Mistake 5: Using the Wrong Tools

I recently helped a customer who’d used regular pliers instead of a pipe wrench, causing:

• Surface damage to pipes.
• Weak points in the system.
• Future leak risks.
• Improper connections.

Modern Solutions for Noisy Pipes

Technology has come a long way since I started plumbing. Today, we have access to:

• Advanced water hammer arrestors.
• Flexible pipe connectors.
• Sound-dampening pipe insulation.
• Smart pressure regulation systems.
• Modern venting solutions.

Seasonal Maintenance Tips for Perth Homes

Our climate requires specific attention throughout the year:

Summer:

• Check for expansion noises as pipes heat up
• Monitor outdoor pipe exposure
• Inspect irrigation system connections

Winter:

• Listen for contraction noises in colder weather
• Check pipe insulation
• Monitor hot water system performance

Spring/Autumn:

• General system inspection
• Pressure testing
• Valve maintenance

When to Call a Professional

From my experience, call a plumber when you notice:

• Sudden new noises
• Increasing noise volume
• Multiple types of sounds
• Noises accompanied by other issues
• Changes in water pressure
• Visible pipe movement
