Blocked drains always catch you off guard, they love to cause you grief with slow drainage, unpleasant odours, or even disgusting overflows that affect your home or workplace. Dealing with foul-smelling sewer or stormwater issues is an experience most people would rather avoid.

Allied Plumbing on the Sunshine Coast delivers fast, reliable drain unblocking services that tackle both the immediate symptoms and the underlying issues. Using advanced equipment, we accurately locate blockages caused by grease, tree roots, or broken pipes and remove them efficiently. From minor clogs to major drainage problems, we handle everything with minimal disruption and strive for solutions that last. Rather than relying on quick fixes or guesswork, we ensure your drains stay clear and functional with genuine repairs.

Signs it’s blocked?
  • Water draining slow (sink, shower, toilet)
  • Gurgling sounds in pipes
  • Bad smells coming up
  • Water backing up / overflowing
When it’s time to call a plumber?
  • Multiple fixtures backing up (toilet + shower etc.)
  • Sewage smell
  • Outside drains overflowing
  • Keeps coming back

What we can do:

Blocked Toilet
A blocked toilet can quickly disrupt your day, with water rising, slow flushing or overflow. Often caused by excess paper, waste or foreign objects restricting the line, we remove the obstruction to restore clean, reliable flushing.
Blocked Bath Drain
Bath drains can gradually clog with hair and product build up, leading to slow drainage and standing water. We remove the blockage and ensure your drainage system is working cleanly and efficiently again.
Blocked Shower Drain
Water pooling around your feet is often the first sign of a blocked shower drain. Hair, soap residue and debris can build up over time, restricting flow. We clear the line and get your drainage moving freely again.
Blocked Kitchen Sink
Grease, food waste and residue can build up in kitchen sink pipes, leading to slow drainage and blockages. We remove the build up and get your sink draining cleanly again.
Blocked Laundry Drain
Laundry drains can become blocked from lint, detergent residue and debris over time, leading to slow drainage or overflow. We clear the blockage and restore reliable flow so your laundry runs as it should.
Blocked Basin Drain
A blocked basin drain is often caused by a build up of soap, hair and everyday debris over time. We locate the cause and clear the blockage properly to restore reliable drainage.
Blocked Sewer
Blocked sewer lines are often caused by debris, tree roots or build up within the pipe, restricting how waste moves through the system. This can lead to wastewater backing up through drains and unpleasant odours. We locate the blockage and clear the line to restore safe, effective flow.
Blocked Downpipe
Leaves, dirt and debris can build up in downpipes, especially after heavy rain, causing water to back up or overflow. We remove the obstruction and restore proper drainage to protect your property.
Blocked Stormwater
Blocked stormwater systems can lead to pooling water, slow runoff and drainage issues around your property. We locate the blockage within the line and clear it to restore effective water movement during rainfall.

Allied Plumbing’s Blocked Drain Cleaning Process

1. Precision Pipe Locating

Locating blocked underground drains used to be a frustrating and lengthy process, often filled with guesswork and unnecessary excavation. Now, we use electronic locators that pinpoint the exact location of faults.

Additionally, our Sunshine Coast plumbers can determine the depth and direction of pipes beneath the ground using this technology. As a result, we can inspect drains thoroughly, address issues more efficiently, and repair or replace damaged or broken pipes with minimal disruption, mess, and expense for you.

2. Diagnostic CCTV Camera Surveys

Once the location is identified, high-definition CCTV camera technology is employed to assess the internal condition of the drainage system. A waterproof, flexible camera is inserted into the sewer or stormwater pipe, supplying real-time visual data of the interior. This approach enables the precise identification of issues such as invasive tree roots, misaligned pipes, or structural cracks without the need for excavation.

Homeowners are invited to observe the live footage alongside our team, providing a transparent overview of the underlying problem. This clarity facilitates informed decision-making regarding remedial actions, whether a straightforward clearing or a more comprehensive repair such as pipe relining.

Additionally, cameras are utilised post-cleaning to confirm that all debris has been eliminated, ensuring thoroughness and accuracy.

3. Advanced High-Pressure Clearing

Traditional tools may clear minor clogs, but persistent blockages on the Sunshine Coast often require professional solutions. Our team uses truck-mounted hydro-jetters with specialised nozzles for different sewer and stormwater maintenance jobs. High-pressure water is directed through pipes, thoroughly cleaning the inner walls.

Hydro-jetting is far more effective than using an electric eel. It breaks up heavy debris and tree roots while removing grease and silt that can lead to future clogs. Because it relies on water pressure rather than mechanical friction, hydro-jetting safely and non-invasively restores your pipes to a near-new condition.
