What’s Blocking Your Drains, Brisbane?
Blocked drains are all too common in Brisbane—thanks to a mix of leafy suburbs, storm-heavy weather, and ageing plumbing. Knowing what causes them (and what signs to look for) can help you avoid a plumbing disaster.
What Causes Most Drain Blockages
In Brisbane, common culprits include:
- Grease and oil poured down kitchen sinks
- Hair and soap buildup in bathroom drains
- Wet wipes and hygiene products flushed down toilets
- Leaves and silt in outdoor stormwater drains
- Tree roots growing into cracked or unsealed pipes
With Brisbane’s subtropical climate, tree root invasions are particularly aggressive—yes, they can and do break through drain pipes searching for water.

How Do I Know if My Drain Is Partially Blocked?
Early warning signs to watch for:
- Slow-draining sinks or showers
- Gurgling sounds from drains or toilets
- Unpleasant smells coming from pipes
- Toilets that struggle to flush or refill slowly
These are signs your drain is starting to clog—and it’s time to consider professional drain clearing.
What’s the Difference Between Sewer and Stormwater Blockages?
- Sewer blockages affect your internal plumbing—think toilets, basins, and kitchen drains. These blockages can quickly turn messy and require urgent attention.
- Stormwater blockages affect external drainage systems—gutters, downpipes, and ground drains. Heavy rain can make these overflow fast, especially if they’re full of leaves and debris.
Why Do Blocked Drains Gurgle
That gurgling sound is air trapped in the pipes. It’s trying to escape past a blockage, which often means the water flow is already being restricted. It’s one of the most common (and early) signs of trouble.
The Hidden Health Hazards of Blocked Drains
In Brisbane’s warm, often humid climate, blocked drains don’t just disrupt your routine—they can seriously impact your health and home. Here’s why it’s important not to delay.
Can Blocked Drains Make You Sick
Yes. When water stagnates due to a blockage, it becomes a breeding ground for bacteria and viruses. This can lead to gastrointestinal issues, skin irritation, and infections—especially in kids, the elderly, and anyone with a weakened immune system.
Are Sewer Backups Dangerous
Absolutely. Sewer overflows can release E. coli, salmonella, and other harmful pathogens into your home. The risk of contamination is high, and exposure to raw sewage can pose serious health risks. If this happens, leave the area and call a professional immediately.
Do Blocked Drains Attract Pests
Yes—cockroaches, rats, and drain flies love the dark, damp conditions inside blocked pipes. Once inside, they can spread bacteria and trigger allergies. And in Brisbane’s climate, pest infestations can grow fast.
Can Stagnant Water Cause Mould
Definitely. Water sitting in or under your home due to a blockage creates the perfect conditions for mould and mildew. These release spores that can affect your lungs, especially if you suffer from asthma or allergies.
Are Mosquitoes a Risk With Blocked Stormwater Drains
They are—especially in Brisbane. When stormwater drains are blocked, rainwater pools and becomes a mosquito breeding ground. That raises the risk of diseases like Ross River virus and Dengue Fever, both of which are found in parts of Queensland.
When a Blocked Drain Becomes an Emergency in Brisbane
Some drain problems you can live with for a day. Others? You need help immediately. Knowing the signs of a plumbing emergency can save your property—and your health—from serious harm.
Is It an Emergency? Here's When to Act Fast.
If you notice sewage overflowing from a toilet, floor drain, or outdoor gully—stop everything and call us. This is a clear emergency. Raw sewage carries dangerous bacteria and can damage floors, walls, and electrical systems in no time.
What If Wastewater Backs Up Into the Shower?
That means your sewer line is blocked and waste has nowhere to go. It’s a red flag that the system is under pressure—and could fail completely. Don’t run more water. Call Reactive Plumbing & Electrical straight away.
Can a Severe Blockage Burst My Pipes?
Yes, and it happens more often than you think. Pressure building behind a blockage—especially in older or poorly installed pipes—can lead to cracks, leaks, or complete bursts, causing major indoor flooding and costly water damage.
What's Causing the Rotten Egg Smell
That unpleasant rotten egg odour is likely methane gas from trapped organic waste. Aside from being offensive, methane in high concentrations can be flammable. If you smell it, don’t ignore it—it’s a clear warning something’s wrong in the pipes.
Fast Emergency Response Across Brisbane
Reactive’s emergency plumbing team is on standby to respond quickly—often same-day—anywhere in Brisbane. With fully stocked vehicles and advanced tools, we’re ready to solve sewage overflows, severe blockages, and drainage issues safely and efficiently.
DIY or Call the Pros? Here’s the Truth About Blocked Drains
When a drain slows down or starts gurgling, it’s tempting to fix it yourself. And sometimes, a plunger might do the trick. But not all blockages are created equal—and some quick fixes can do more harm than good.
Are Chemical Drain Cleaners Safe
They might seem convenient, but most chemical drain cleaners are corrosive—especially in older Brisbane homes with ageing pipework. They can eat away at pipe walls, weaken joints, and create bigger issues down the track. At best, they’re a temporary fix. At worst, they add to the damage.
When Should I Call a Professional?
If:
- The plunger isn’t working
- Water keeps backing up after a few days
- Multiple drains are affected
- You smell something foul or hear gurgling
…it’s time to call in the pros. These are signs of a deeper or more complex blockage that DIY methods won’t reach.
Can a Blocked Drain Clear Itself
No—and hoping it will is risky. In most cases, the blockage slowly gets worse, building pressure in your pipes and increasing the chance of a major backup or burst. Drain problems never get cheaper to fix with time.
Why Don’t My DIY Fixes Last
Because most DIY methods only treat the symptoms—not the source. Whether it’s a bit of boiling water, a coat hanger, or a drain snake, they rarely remove the full blockage. That’s why the problem returns.
How Do Professionals Solve It Long-Term
At Reactive, we go deeper:
- CCTV drain cameras let us locate the exact blockage
- High-pressure hydro-jetting clears the pipe and cleans the walls
- Root-cutting equipment removes tree invasions
- Pipe relining fixes structural damage with no digging
Our goal isn’t just to clear your drain—but to make sure it stays clear.
Stop the Blockage Before It Starts: Simple Prevention Tips
In Brisbane, where heavy rain, leafy trees, and older homes are common, blocked drains can sneak up on you fast. The good news? With a few smart habits and regular maintenance, most clogs can be avoided entirely.
What Habits Help Prevent Drain Blockages?
Small changes go a long way:
- Never pour grease or cooking oil down the sink—let it solidify and bin it
- Use sink strainers and hair catchers in kitchens and bathrooms
- Flush only toilet paper—no wipes, tissues, or sanitary items
- Rinse bathroom basins regularly to keep soap scum and hair from building up
- Clear gutters and downpipes to stop leaves entering your stormwater drains
How Often Should Drains Be Professionally Cleaned
Most homes benefit from a professional drain clean every 12 to 24 months—especially older properties or those with heavy tree coverage. If you’ve had blockages in the past, it’s worth scheduling cleans more regularly to stay ahead of issues.
Do Drain Guards Really Work
Absolutely. Drain guards and strainers are simple, affordable tools that prevent food, hair, and debris from going where they don’t belong. They’re one of the easiest ways to protect your plumbing.
Can Hydro-Jetting Help Prevent Future Clogs
Yes. Hydro-jetting doesn’t just remove blockages—it cleans the interior of your pipes, blasting away grease, scale, and buildup that cause recurring problems. It’s especially useful in homes where kitchen or bathroom drains clog frequently.
Why Are My Kitchen Drains Always the Problem
Kitchens see the worst of it—grease, fats, coffee grounds, and food scraps all make their way down the drain. Even with hot water, grease cools and sticks to the pipe walls, creating the perfect trap for future clogs. That’s why kitchen sinks are usually the first to block.
How We Clear Drains in Brisbane—And What It’ll Cost
When your drain’s blocked, you want answers fast—and no nasty surprises on the bill. At Reactive Plumbing & Electrical, we make the process simple, transparent, and thorough.
How Much Does Emergency Drain Clearing Cost
Emergency drain clearing in Brisbane generally starts from $250–$350, depending on the severity and location of the blockage. We’ll always provide a clear, upfront quote before we start, so you know exactly what to expect.
What’s the Difference Between Snaking and Hydro-Jetting
- Snaking uses a rotating cable to punch through blockages. It’s ideal for soft clogs and simple fixes.
- Hydro-jetting uses high-pressure water to fully clean your pipes, removing stubborn grease, roots, and scale buildup.
Both are effective—but we’ll always recommend the method that’s best for long-term results, not just the quick fix.
Do You Use CCTV to Inspect Drains
Yes—we use high-definition CCTV cameras to look inside your pipes in real time. This helps us:
- Pinpoint the exact location and cause of the blockage
- Detect hidden issues like cracks or root invasions
- Avoid unnecessary digging or damage
It’s one of the reasons our work is faster, more accurate, and longer-lasting.
Can You Solve Recurring Drain Problems
Definitely. If you’re dealing with the same blockage over and over, there’s likely a deeper issue—tree roots, poor pipe alignment, or a hidden break. We’ll find it and fix it properly, so you’re not stuck in a cycle of repeat callouts.
Do You Guarantee Your Work
Yes. Most of our drain clearing services include a warranty, especially when paired with camera inspection or hydro-jetting. If we’ve cleared it and the problem comes back—we’ll make it right.
