Quick Answer
What is a blocked drain service?
A blocked drain service identifies and clears an obstruction stopping water from draining properly through your plumbing. Aussie Dave’s Plumbing uses CCTV drain cameras to confirm the exact cause before clearing, rather than guessing. Most blockages are cleared in a single visit using high-pressure jetting or targeted mechanical clearing, with an upfront, fixed price agreed beforehand.
About Our Blocked Drain Service
Clear the blockage and fix the cause.
Blocked drains are one of the most common plumbing issues Sydney homeowners face, and they’re rarely random. Older suburbs often deal with tree roots in ageing pipes, while newer homes are more likely to experience grease, hair, and everyday debris build-up. Both causes are fixable, but they need different approaches.ith the right urgency. A burst pipe at 2am, no hot water before work, or an overflowing toilet can all feel urgent in the moment. Some genuinely can’t wait a single hour. Others can safely hold until a scheduled visit without causing further damage to your home.
Diagnosis comes first.
Our process starts with diagnosis, not guesswork. A CCTV drain camera lets us see exactly what’s causing the blockage and where it sits in the pipe before recommending the best way to clear it.
More than a temporary fix.
Clearing a blockage is only half the job. We focus on solving the underlying problem, whether that’s clearing grease build-up or identifying a damaged pipe causing repeated blockages.
Built for Sydney homes.
Sydney’s older suburbs with mature trees and original clay pipes are more prone to root intrusion, while newer developments with PVC drainage face different issues. We understand the common drainage problems across different types of Sydney properties.
Solutions that last.
A temporary clear that returns in a month isn’t a real fix. Our goal is to provide a long-lasting solution, so you don’t have to deal with the same blocked drain again.
Common emergency Problems
Know the signs. Act fast. Prevent bigger damage.
Blocked drains tend to show consistent warning signs before they escalate into a full blockage. The table below sets out what to watch for, what’s likely causing it, and what happens if it’s left unaddressed.
Water draining slowly from sinks, showers, or baths.
Grease, fat, hair, or soap scum building up inside the pipe.
Risk: A slow drain escalating into a complete blockage over time.
Gurgling sounds from drains or toilets.
Air trapped behind a partial blockage further down the line.
Risk: The blockage worsening until water fully backs up.
Bad odours coming from drains around the home.
Trapped organic matter decomposing inside the pipe.
Risk: Ongoing unpleasant smells and a worsening blockage.
Water backing up in the lowest drain when using another fixture.
A blockage in the main line affecting multiple connected fixtures.
Risk: Sewage backflow into the home through affected fixtures.
Overflowing gully traps in the yard.
A blockage further along the sewer line pushing water back.
Risk: Wastewater pooling in the yard, creating a health hazard.
Toilets not flushing properly or refilling with dirty water.
A significant blockage in the sewer line near the toilet connection.
Risk: Sewage contamination inside the home if left untreated.

FAQS
Frequently Asked Questions
What causes blocked drains in Sydney homes?
Common causes include grease build-up, hair and soap scum, and tree root intrusion into sewer lines. Older suburbs with established trees see root intrusion more often than newer developments. Non-flushable items like wipes are another frequent cause.
How much does it cost to clear a blocked drain in Sydney?
Cost depends on the blockage’s severity, location, and whether CCTV inspection is needed. We’ll always confirm a fixed, upfront price once we understand what’s causing the issue. This avoids any surprises once the work begins.
Can tree roots really block a sewer pipe?
Yes, tree roots are drawn to moisture and can enter pipes through small cracks or joints. Once inside, they grow rapidly and can cause a complete blockage over time. This is especially common in older clay pipework.
How do I know if my blocked drain needs a CCTV inspection?
Recurring blockages, multiple affected fixtures, or an unclear cause are all good reasons for a CCTV inspection. It lets us see exactly what’s happening inside the pipe rather than guessing. This avoids unnecessary repeat call-outs.
Is it safe to use chemical drain cleaners?
Not always. Chemical cleaners can damage older pipe materials and are largely ineffective against tree root intrusion. They can also mask a bigger problem rather than actually solving it. We recommend proper diagnosis instead.
What is high-pressure water jetting?
High-pressure jetting uses a controlled water stream to clear blockages and built-up debris from inside a pipe. It’s effective against grease, root intrusion, and general build-up without damaging the pipe itself. It’s one of our most commonly used clearing methods.
How long does it take to clear a blocked drain?
Most single-fixture blockages are cleared within an hour once we’re on-site. More complex main line blockages involving CCTV inspection and jetting can take longer. We’ll give you a realistic timeframe after our initial assessment.
Can a blocked drain cause sewage to back up into my house?
Yes, a severe blockage in a main line can force sewage back through connected fixtures. This is treated as an urgent issue due to the health risk involved. Call us immediately if you notice any backflow.
Do you repair pipes damaged by tree roots?
Yes, we assess the extent of root damage and recommend either clearing, repair, or relining depending on severity. Minor intrusion can often be cleared and monitored. More significant damage may need a longer-term structural solution.
What is pipe relining and when is it needed?
Pipe relining creates a new internal pipe surface without full excavation of the damaged section. It’s typically used for cracked, damaged, or root-affected pipes that can’t be cleared alone. It’s a less disruptive alternative to full pipe replacement.
Why does my drain gurgle?
Gurgling usually indicates trapped air caused by a partial blockage further down the line. It’s often an early warning sign before a full blockage develops. Addressing it early can prevent a more disruptive issue later.
Can I prevent blocked drains?
Yes, using drain strainers, avoiding grease disposal down sinks, and only flushing toilet paper all help significantly. Periodic professional maintenance is also worth considering near mature trees. Small habits make a real difference over time.
Do you offer emergency blocked drain services?
Yes, severe blockages causing overflow or backflow are treated as emergencies and prioritised accordingly. Our team is available for urgent call-outs across Sydney. See our Emergency Plumbing page for more detail.
What's the difference between a blocked drain and a blocked sewer?
A blocked drain typically affects a single fixture or a short section of pipe. A blocked sewer affects the main line carrying wastewater away from the whole property. Sewer blockages tend to cause more widespread symptoms across multiple fixtures.
Can old clay pipes still be repaired, or do they need full replacement?
Many older clay pipes can be repaired or relined without full replacement, depending on the extent of damage. A CCTV inspection helps us assess the pipe’s condition accurately. We’ll always recommend the least disruptive option that solves the problem properly.
Do you provide a written report after CCTV drain inspection?
Yes, we can provide footage and a summary of findings after any CCTV inspection. This is useful for your own records or for insurance and property documentation. Just let us know if you’d like one provided.
Are blocked drains covered by home insurance?
Coverage varies by insurer and policy, particularly around gradual damage versus sudden blockages. We can provide documentation to support a claim where needed. Check your specific policy for exact terms.
What should I avoid putting down my drains?
Avoid grease, fat, oil, wipes, sanitary products, and food scraps in sinks, toilets, and drains. These are among the leading causes of blockages we see across Sydney. Small changes to household habits go a long way.
Can a blocked stormwater drain cause flooding?
Yes, a blocked stormwater drain can cause water to pool or flood during heavy rain. This is a separate system from your sewer line but follows similar blockage causes. We assess and clear both stormwater and sewer blockages.
Do apartment and strata buildings get blocked drains too?
Yes, shared drainage systems in apartments and strata buildings are just as prone to blockages. We regularly work with strata managers to diagnose and resolve shared line issues. Building access and coordination are handled as part of the job.
Pricing Guide
What affects your price?
Emergency plumbing pricing depends on several factors specific to your situation, and we’ll always confirm your price before any work begins.
Blockage severity
A single fixture blockage generally costs less than a main line blockage.
Whether CCTV inspection is needed
Diagnosis-first jobs add a step but prevent unnecessary repeat call-outs.
Access to the affected pipework
Roof vents, underfloor spaces, and difficult access can add complexity.
Cause of the blockage
Tree roots or structural damage may need additional repair beyond clearing.
Time of service
After-hours or emergency call-outs carry a higher rate than standard hours.
