Jet Blasting Sydney
Same Day, $0 Call Out, Lifetime Warranty

What Is Jet Blasting?

A high-pressure water pump, a flexible jetter nozzle, and enough PSI to cut through tree roots. That’s jet blasting. We feed the nozzle through the drain line and the water pressure does the work, cutting through blockages, stripping grease off pipe walls, flushing everything cleanly out of the system.
You’ll also hear it called hydro jetting, high-pressure drain cleaning, or drain jetting. Same thing.

Jet Blasting vs a Drain Snake

This is the question we get asked most. Here’s the honest answer.
 
A drain snake bores through a blockage mechanically. It gets the water moving again, but it leaves debris on the pipe walls. For root intrusions, it tends to punch a hole through the root mass rather than remove it. The roots recover. The drain blocks again, usually within a few months.
 
Jet blasting flushes the line completely. The nozzle cuts through the root mass, the water pressure washes the walls clean, and everything gets pushed out of the system. The drain stays clear for significantly longer because the cause has been cleared, not just punctured.
 
For clay and terracotta pipes, which is what most Inner West homes have, jet blasting is the right tool. A drain snake can catch on old pipe joints and cause mechanical damage. The jetter flows through and cleans without that risk.
 
A snake clears a blockage. A jetter clears the pipe.

Our Jet Blasting Process

Every Sydney job is a bit different, but the structure stays the same. Here’s what to expect when we turn up to clear an Inner West drain.

Step 1: On-site assessment

Your plumber confirms the symptoms, finds the best access point (usually an inspection opening or a roof vent) and works out the right pressure for your pipe material. A lot of Inner West homes from Newtown to Haberfield run on terracotta, so this first read matters.

Step 2: CCTV inspection when needed

If the cause isn’t obvious or the drain keeps blocking, a camera goes down first. You see what we see, on the screen. This step also tells us whether the pipe’s in good shape to jet, or whether structural work needs to happen first.

Step 3: Nozzle selection

Different nozzles do different jobs. A penetrator nozzle cuts through tree roots. A flushing nozzle washes the grease and silt out. A rotating nozzle scours the pipe walls clean without parking water in one spot. Your plumber picks the right head before any water moves.

Step 4: Controlled high-pressure clearing

Water at the correct pressure for your pipe is fed down the line. The nozzle pulls itself through the blockage, scrubbing the pipe wall as it travels. Pressure’s matched to the pipe, not blasted at maximum. That’s the difference between a clear drain and a damaged one.

Step 5: Flow test and
tidy up

Once the line runs clean, we run water through to confirm full flow, walk you through what we found, and leave the area as we found it. If you’d like, we’ll set a maintenance reminder so you’re not waiting for the next block to call us back.

What Jet Blasting Clears

Jet blasting uses controlled high-pressure water and specialist nozzles to:

Bacteria icon
Grease

Grease coats pipe walls over years and narrows the bore. The jetter strips it off and flushes it out in a single pass.

Icon of grass blades
Tree roots

The root-cutting nozzle spins as it moves through the line, cutting through the mass and flushing the debris out. We re-run the camera after to confirm the line is clear.

Water stain icon
Soap scum and scale

Bathroom lines accumulate soap scum, shampoo residue and mineral scale. The jetter cleans it all in one pass.

Blocked Toilet Repair icon
Stormwater debris

Leaves, soil and organic matter in outdoor drains clear cleanly.

When We Use It

We run a CCTV inspection through the drain before we jet. If the camera shows a cracked or structurally compromised pipe, we won’t jet it until the structural issue is assessed. Jetting into a badly deteriorated pipe can make things worse.
We also use jet blasting as part of every pipe relining job. The pipe needs to be thoroughly cleaned before the liner goes in.

What to expect on price

Standard jet blasting jobs are cleared from $139. That covers the call, the on-site assessment, and high-pressure water jetting to clear routine blockages like grease, sediment, or light root intrusion. More severe issues, the kind involving heavy root masses, collapsed sections, or damaged pipework, are quoted separately once a CCTV inspection confirms the cause. You’ll know the full price before we start. $0 call-out fee on every job.

QUESTIONS

Not when it’s done properly. We always check pipe condition with a CCTV camera before we start, then match nozzle and pressure to what we see. Old clay and terracotta pipes in Inner West Federation homes get a gentler pass than modern PVC. The point is to clear the line without making a bad pipe worse.

Pricing depends on access, line length and what’s blocking the drain. Most residential jet blasting jobs are quoted on site once we’ve inspected with the camera. See our full pricing for the wider blocked drain pricing structure.

Most residential jobs are done in one to two hours, including camera inspection before and after. Stubborn root intrusion in clay sewer lines takes longer. Same-day across the Inner West and we work weekends. Call us today to book a slot.

Yes. High-pressure drain jetting on residential plumbing needs a licensed plumber. Champion Plumbing & Drains holds Licence No. 371639C with full insurance. Every job is backed by our lifetime labour guarantee, so if the work fails we come back and fix it at no charge.

Champion clears most residential drains from $139, with a $0 call-out fee. Across Sydney, jet blasting typically sits between $250 and $600 for harder jobs with longer line runs or heavier blockages. Final cost depends on access, line length and what’s causing the block. We give you a fixed price before any work starts, so there are no surprises on the invoice. See our pricing page for the full breakdown.

Yes, when the pressure’s matched to the pipe. Many Inner West homes still have terracotta or earthenware drains, which need a careful hand. We run a CCTV camera first to check for cracks, collapsed sections or loose joints. Pressure’s then dialled to clear the line without stressing the pipe, and a rotating nozzle keeps the water moving so it can’t drill in one spot. A licensed plumber on controlled equipment is the safe option for older Sydney pipes.

Jet blasting cuts and flushes roots out of the line, so the drain runs again straight away. The trees keep growing, though, so roots can find their way back through the same cracks and joints. Most Sydney homes get 12 to 36 months of clear flow before regrowth becomes an issue. For a permanent fix, pipe relining seals the cracks the roots enter through, so they can’t get back in. Jet blast first, reline if the problem returns.

For most Sydney homes, every 18 to 24 months keeps build-up under control. If you’re on older terracotta pipes, have large trees near the sewer line, or you’ve had repeat blockages, every 12 months is the safer schedule. Homes with heavy grease use (think frequent cooking, lots of dishes) sit closer to every 12 months, too. We can set a reminder after the first job so the calendar thinks for you.

A snake’s a flexible cable with a cutting head. It punches through a single blockage point and gets the drain running again. Jet blasting uses high-pressure water through a directional nozzle to clean the inside of the pipe end to end. A snake clears the clog. Jet blasting clears the cause. For a one-off, simple block, a snake’s often enough. For grease, roots, recurring blocks or a pipe that needs the walls scoured clean, jet blasting’s the better option. There’s more on both methods on our blocked drains page.
