Blocked Drain Clearing with CCTV Inspection & Hydro Jetting

The Real Causes of Blocked Drains in Sydney’s Eastern Suburbs

Blocked drains are the number-one call-out for plumbers across the Eastern Suburbs, and for good reason. The area’s unique combination of mature street trees, heritage housing stock and clay sewer infrastructure creates a perfect storm for recurring blockages.

In suburbs like Woollahra, Bellevue Hill and Vaucluse, century-old Moreton Bay figs and Port Jackson figs send aggressive root systems directly into sewer joints. In Surry Hills and Darlinghurst, converted terraces with original cast iron waste lines suffer from corrosion and scale build-up that narrows the pipe bore over decades. And in newer developments around Mascot and Zetland, construction debris and improper fall on drainage lines cause premature blockages.

Understanding the cause is the key to a lasting fix — and that is exactly why Mr Plumber starts every blocked drain job with a CCTV camera inspection.

How We Clear Blocked Drains

Step 1: CCTV Drain Camera Inspection

We feed a high-definition, self-levelling camera through the pipe from the nearest access point. The live feed shows the exact location, depth and nature of the blockage — whether it is a mass of tree roots at the joint 8 metres from the house, a grease dam under the kitchen, or a collapsed section of clay pipe beneath the driveway.

The camera also records a sonde signal, allowing us to mark the blockage location on the surface with pinpoint accuracy. This is critical when pipe relining or excavation is required.

Step 2: High-Pressure Hydro Jetting

Once we know what we are dealing with, we deploy our hydro jetter — a machine that delivers a targeted stream of water at pressures up to 5,000 PSI. Unlike a traditional drain snake or electric eel that simply pokes a hole through the blockage, hydro jetting scours the full circumference of the pipe. You can compare hydro jetting vs drain snaking to understand why we favour jetting for most Eastern Suburbs blockages. The result is a pipe that flows as freely as the day it was installed.

For tree root blockages, we use a rotating root-cutting nozzle that slices through even the densest root masses. For grease and fat accumulations — common in restaurant drain lines across Bondi Junction and Surry Hills — we use a degreasing nozzle combined with hot water to dissolve and flush the build-up completely.

Step 3: Post-Clear Verification

After clearing, we run the camera through the pipe a second time. This post-clear inspection serves two purposes: it confirms the blockage is fully removed, and it reveals the underlying condition of the pipe. If we find cracks, joint displacement or early-stage root intrusion, we can recommend preventive measures such as pipe relining before the problem recurs.

You receive the before-and-after CCTV footage so you can see exactly what was causing the issue and verify the quality of the work.

Common Blocked Drain Scenarios

Kitchen Drains

Grease, cooking oil and food scraps are the primary culprits. Over time, fats solidify inside the pipe and trap other debris, creating a stubborn blockage that household drain cleaners cannot touch. Our hydro jetting cuts through grease dams and restores full flow.

Bathroom and Shower Drains

Hair, soap scum and mineral scale gradually narrow the pipe. In hard-water areas of the Eastern Suburbs, calcium deposits compound the problem. We clear the blockage and can install hair traps to prevent recurrence.

Toilet Blockages

Foreign objects — wet wipes, sanitary products and children’s toys — are the usual suspects. We use a combination of specialised augers and hydro jetting to retrieve or clear the obstruction without damaging the ceramic bowl or PVC waste line.

Main Sewer Line Blockages

When multiple fixtures back up simultaneously, the blockage is usually in the main sewer line between your house and the Sydney Water main. Tree roots are the leading cause. We access the line through the overflow relief gully (ORG) or nearest inspection opening and jet the full length of the sewer back to free-flowing condition.

Stormwater Drains

Leaves, silt and debris accumulate in stormwater pits and pipes, especially after heavy rain. Blocked stormwater drains cause yard flooding and can direct water towards your foundations. We clear stormwater lines and pits and can install leaf guards to reduce future maintenance.

Preventing Blocked Drains

While we are always happy to clear a blockage, prevention is better — and cheaper — than cure. For a detailed pricing breakdown, see our guide on blocked drain clearing costs in Sydney. Here are the steps we recommend to Eastern Suburbs homeowners:

• Schedule a CCTV inspection every two years to catch tree roots and pipe deterioration early.
• Install a grease trap if you cook with oil frequently. This is mandatory for commercial kitchens under Sydney Water trade waste requirements.
• Never flush wet wipes, even those labelled “flushable”. They do not break down like toilet paper and are a leading cause of sewer blockages.
• Keep gutters and stormwater pits clear of leaves and debris, particularly in autumn.
• Consider pipe relining if your CCTV inspection reveals cracked joints or early root intrusion. Relining seals the pipe from the inside and prevents roots from re-entering.
