Plumbing problems are every homeowner’s nightmare—and in Australia, where extreme weather and aging infrastructure collide, even a small issue can turn into a major disaster fast. Whether it’s a dripping tap, a blocked drain, or a cold shower on a winter morning, ignoring early signs can lead to high water bills, serious water damage, and expensive emergency repairs.
In this guide, we’ll explore the five most common plumbing issues in Aussie homes—and exactly what you should do before they become budget-breaking headaches.
Looking for plumbing services in Australia? We’ve got you covered too.
1. Leaking Taps: Small Drip, Big Waste
You might think a dripping tap is harmless, but over time it can waste thousands of litres of water and spike your water bills. The most common cause is a worn-out washer or O-ring, but corrosion and pressure build-up can also play a role.
How to fix it:
If it’s a basic washer issue, confident DIYers can change it out easily. But if the tap still leaks after replacement, it may be time to call a licensed plumber in Australia. We often find hidden pipe corrosion behind persistent leaks—something only a professional can detect.
Tip: Fix leaks early to avoid damaging cabinetry, flooring, or walls.
2. Blocked Drains: The Slow Sink That Signals Trouble
Is your sink draining slowly? Or worse—backing up? Blocked drains are among the most common plumbing problems in Australian homes, caused by hair, food scraps, grease, or tree roots in outdoor pipes. If left untreated, they can lead to serious backups or even burst pipes.
What to do:
Try plunging first. Avoid using chemical drain cleaners—they can cause pipe corrosion. For recurring issues, you’ll need a plumber with the right tools to inspect and clear the blockage properly.
Need help fast? We offer emergency drain unblocking services across Australia, with equipment that clears pipes without damaging them.
3. Low Water Pressure: Annoying and Often Overlooked
Low water pressure makes showers weak and washing up frustrating. It may seem like a minor nuisance, but it often signals a bigger plumbing problem. Sediment build-up, corroded pipes, hidden leaks, or a faulty pressure valve could be the root cause.
What to check:
Clean your tap aerators and shower heads—they may be clogged with mineral deposits. If pressure remains low throughout the house, it’s time to call in a professional. You might have a leak underground or inside your walls.
Regular maintenance from your local plumbing service can keep pressure stable and systems efficient.
4. Running Toilets: Easy to Miss, Expensive Over Time
If your toilet never stops refilling, you’re silently wasting hundreds of litres of water per day. Faulty flapper valves, misaligned floats, or corroded seals are often the cause.
What to do:
Lift the tank lid and inspect the float and flapper valve. You can replace them with a basic kit from a hardware store. But if your toilet is older or the issue comes back, a plumber can check for deeper problems with the flush mechanism or tank seals.
A running toilet can add hundreds to your water bill each year—don’t ignore it.
5. Hot Water System Failure: Cold Showers and Warning Signs
A sudden loss of hot water is a clear sign that your system needs attention. Whether it’s discoloured water, strange noises, or inconsistent temperatures, these warning signs shouldn’t be ignored.
What to do:
Older systems (8+ years) may need replacing. Newer units often benefit from annual servicing—flushing out sediment, checking thermostats, and inspecting valves. At All About Home Maintenance, we service and replace hot water systems from all major brands across Australia.

When to Call a Professional Plumber in Australia
Some issues can be handled with a wrench and a YouTube video. But many require the expertise of a licensed plumber—not just for safety, but for compliance with Australian building codes.
Call a plumber if:
- The same problem keeps returning
- Water stains or mould appear
- You lose water pressure suddenly
- Your water bills spike for no reason
- You hear gurgling sounds from pipes or toilets
At All About Home Maintenance, we provide fast, professional plumbing services across Australia, including 24/7 emergency support when you need it most.
How to Prevent Plumbing Disasters Before They Start
Plumbing issues rarely start big—they grow over time. The best way to protect your home is to be proactive. Here are four smart prevention tips:
- Clean your drains monthly using natural solutions (like baking soda and vinegar)
- Never pour grease or oil down the sink—it hardens and blocks pipes
- Install drain screens in bathrooms to catch hair and debris
- Schedule annual inspections for your hot water system and visible pipework
Our general repair services include preventative plumbing maintenance to help you stay ahead of problems—before they flood your laundry room.
