What causes most blocked drains in Sydney?
The most common causes of blocked drains in Sydney are tree root intrusion, grease and fat buildup in kitchen lines, broken or collapsed clay pipes in older suburbs, sediment accumulation in stormwater systems, and foreign objects flushed into sewer lines. Sydney's mature tree canopy. particularly fig trees, liquidambars and camphor laurels. creates significant root pressure that cracks and infiltrates ageing drainage infrastructure.
Why use a vac truck instead of a plumber for a blocked drain?
A standard plumber's electric eel or small jetter can shift minor blockages, but for serious obstructions like compacted tree roots, collapsed pipe sections or heavy sediment buildup, an industrial vac truck is far more effective. Our vac truck combines 4,000 PSI water jetting with powerful vacuum extraction to physically remove the blockage material from the pipe, rather than just pushing it further downstream where it re-blocks. For drains that have failed multiple plumber visits, a vac truck clears the problem permanently.
Do you include CCTV drain inspection with every blocked drain job?
Yes. Every blocked drain clearing job with Pro Expose includes a CCTV drain camera inspection at no extra charge. We run the camera through the pipe after clearing to confirm the blockage is fully removed and to check for structural issues like cracks, root damage or pipe displacement that could cause future blockages. This gives you a clear picture of your drainage condition and helps you avoid repeat callouts.
Do you offer 24/7 emergency blocked drain clearing in Sydney?
Yes. Pro Expose Hydro Vacs provides 24/7 emergency blocked drain response across all of greater Sydney. Overflowing sewers, flooded yards and backed-up drains cannot wait until morning. Call 0438 498 274 any time. day, night, weekends or public holidays. and we will mobilise to your location as fast as possible.
Can you clear both residential and commercial blocked drains?
Yes. We clear blocked drains for residential homes, unit complexes, strata buildings, commercial kitchens, shopping centres, industrial facilities, construction sites and council infrastructure. Our industrial equipment handles pipe diameters from 50mm household lines right up to 600mm stormwater mains. The same vac truck that clears a backyard sewer blockage can also service a commercial car park drain or factory waste line.
How much does blocked drain clearing cost in Sydney?
Blocked drain clearing cost depends on the blockage severity, pipe size, access conditions and whether excavation is needed to repair a damaged section. Pro Expose provides upfront quotes with no hidden fees. For a fast estimate, call 0438 498 274 or text a photo of the drain and your suburb. We will reply with pricing quickly. CCTV inspection is included at no extra charge.
Can you clear tree roots from sewer lines?
Yes, and it is one of the most common Sydney jobs we get. Mature street trees (Moreton Bay fig, eucalyptus, jacaranda, liquidambar) push roots into older clay and earthenware sewer lines, especially in inner-city homes built before 1980. The industrial jetter cuts and flushes the root mass, the vacuum extracts it from the line, and the post-clear CCTV camera confirms the pipe is clear. For severe root intrusion where the pipe wall is damaged, we expose the failed section with the hydro vac so a plumber can replace it. Tree roots almost always come back unless the pipe joint is fixed, so we leave you with a CCTV record showing the entry points.
Can you clear blocked stormwater drains and pits?
Yes. Blocked stormwater drains, sumps and pits are a vac truck strength because the volume of sediment, leaves, sand and silt that accumulates is too much for a plumber jetter to flush downstream. The vac truck removes the material directly from the pit or pipe into the spoil tank. We service residential stormwater pits, commercial car park grates, council pits along footpaths and large industrial stormwater systems. After clearing we run the camera through the line so you can see the downstream flow is clean. See our stormwater excavation service for major stormwater works.
What is the difference between a plumber's jet and an industrial vac truck?
Pressure, flow rate and extraction. A standard plumber's portable jetter typically delivers 2,000 to 3,000 PSI at low flow, designed for short residential lines. The industrial unit on a Pro Expose vac truck delivers 4,000+ PSI at much higher water flow, which cuts compacted root masses and grease cake that a plumber jetter just polishes. The bigger difference is extraction. A plumber pushes the blockage downstream where it often re-blocks within metres. The vac truck extracts the material from the line straight into the spoil tank, removing the root cause. For repeat-blockage drains, a vac truck visit usually fixes what multiple plumber visits could not.
Will the hydro vac damage my pipes when clearing the blockage?
No. The jetter pressure is calibrated for pipe-safe cutting. The water cuts soft material (roots, fat, sediment, debris) without damaging structurally sound PVC, copper, vitreous clay or HDPE pipe walls. The exception is pipe that is already cracked, collapsed or severely degraded. The CCTV camera reveals these conditions during the post-clear inspection. If a pipe is structurally compromised, jetting will not break it further but it will not "fix" it either. We document the damage in the CCTV record so your plumber or insurer has a clear picture before any repair is quoted.
Can a hydro vac truck clear collapsed pipes?
A collapsed pipe section cannot be cleared by jetting alone, because there is no pipe to flow through. What the hydro vac does is expose the collapsed section by excavating from the surface so a plumber can replace it. The CCTV camera identifies the location and the depth, then we hydro vac dig down to the failure point without the risk of striking other services. Once the bad section is exposed and replaced, we backfill and reinstate. This combined "find, expose, replace, restore" workflow with one truck and one crew beats coordinating a separate excavator and spoil truck.
How long does a typical blocked drain clearing job take?
A standard residential blocked drain typically wraps inside 60 to 120 minutes on site. That includes setup, jetting, vac extraction, CCTV camera inspection of the cleared line and pack-down. Stubborn root masses, multi-point blockages, deep mainline blockages or commercial premises with restricted access can extend the job to 3 or 4 hours. Collapsed pipe jobs that need excavation and replacement coordination run longer (typically half-day plus, depending on depth and what the plumber needs). We give you an honest time estimate when we quote so you can plan around it.
