High-Pressure Hydro Jet Drain Cleaning The Industry Gold Standard
Hydro-jetting is the most effective and pipe-friendly way to remove tree roots, fats, grease, scale and sediment from blocked drains. Where an electric eel cuts a hole through a blockage, a high-pressure water jet scours the pipe back to a clean, smooth wall — dramatically reducing the chance of the line re-blocking.
💡 Quick answer: Hydro jetting — also called jet blasting or water jetting — clears blocked drains with a 5000 PSI stream of water that cuts tree roots out, scours grease back to the bare pipe wall and flushes everything clear. It’s safer on ageing pipes than mechanical cutting, and we camera-check the result on every job.
🧰 Jetting vs the Alternatives
| Method | Best for | The catch |
|---|---|---|
| 💦 Hydro jetting | Roots, grease, scale, silt — full pipe restoration | Needs professional gear and a trained operator |
| 🐍 Electric eel | Small internal lines, quick punch-through | Cuts a hole through the blockage rather than removing it |
| 🧴 Chemical cleaners | Almost nothing in a real blockage | Can damage old pipes and make drains dangerous to work on |

Jet Blasting, Sewer Jetting, Water Jetting — Same Job, Different Names
Around Melbourne you'll hear this service called jet blasting, drain jetting, sewer jetting, water jetting or hydro-jetting. They're all the same thing: high-pressure water delivered through a specialist nozzle that cuts the blockage out and scours the pipe clean. Whatever you call it, the result is identical — a fully cleared line, verified on camera, not just a hole punched through the mess.
Jet blasting is our number one tool for blocked sewers and stormwater drains. Unlike a drain snake, the jetter cleans the full diameter of the pipe, which is why jetted lines stay clear for years rather than months.
Common Warning Signs
- Recurring blockages: a line that blocks every few months will benefit far more from jetting than from another eel cable run.
- Tree-root intrusion: root-cutting nozzles slice through fibrous root masses and flush them out completely.
- Grease & fat build-up: commercial kitchens, food courts and apartment risers are cleared in a single visit.
- Heavy scale & silt: old galvanised stormwater pipes and large-bore sewers benefit from de-scaling jets.
- Pre-CCTV cleaning: a clean pipe gives an accurate CCTV survey and a defendable report.
Our Diagnostic & Repair Process
- Risk assessment: we confirm pipe material, age and access. Earthenware, PVC, cast iron and HDPE all have different safe pressure ranges.
- Nozzle selection: we choose between root-cutter, chain-flail, penetrator, flusher or de-scaler heads for the specific blockage.
- Controlled jetting: jet hose is fed in stages, cutting and flushing back to the inspection point.
- CCTV verification: we follow up with a camera to prove the line is clean wall-to-wall.
- Recommendations: if we find structural defects we provide a written quote for pipe relining or excavation.
Equipment We Use
- 5000 PSI petrol trailer jetters: for 100–300mm sewer and stormwater mains.
- Compact electric jetters: for 40–80mm internal drains, basins and laundries.
- Root-cutter & chain-flail nozzles: mechanical cutting action plus high-pressure flushing.
- Recycling systems: water-efficient operation on long jobs.

Frequently Asked Questions
Is there a hydro jet drain cleaning service near me?
Yes — our 5000 PSI hydro jetter covers Melbourne's outer east, the Dandenong Ranges and the Yarra Valley, usually same day. Call Jack direct on 0425 226 636.
Is hydro-jetting safe for old earthenware pipes?
Yes — at the correct pressure. We reduce PSI and flow for fragile lines and choose nozzles that cannot impact the pipe wall. Used correctly, jetting is gentler on old clay than mechanical augers.
How long does a hydro-jet job take?
Most residential blockages are cleared in 45–90 minutes including CCTV verification. Heavy commercial grease lines may take 2–3 hours.
Will jetting kill the tree above my drain?
No. We cut the root mass inside the pipe; the tree continues to thrive. We can also recommend root inhibitors or pipe relining if root return is a concern.
Do I need jetting or just an eel?
If your line has blocked more than once in 12 months, jetting is the right answer. A one-off blockage in a small line can often be eel-cleared.
How much does jet blasting a blocked drain cost in Melbourne?
Most residential jet blasting jobs fall into a fixed-price range that we quote upfront over the phone before any work starts — no hourly surprises. The price depends on access and the length of the line, not how long it takes us. See our blocked drain cost guide for Melbourne for typical pricing, or call Jack for a free phone quote.
Is hydro jetting safe for old clay and earthenware pipes?
Yes — pressure and nozzle are matched to the pipe’s material and condition, and jetting puts no mechanical stress on pipe walls the way rotating cutters can. On fragile lines we camera-inspect first, then jet at a pressure the pipe can safely take.
Are jet blasting and hydro jetting the same thing?
Yes — jet blasting, water jetting, hydro jetting and sewer jetting all describe the same process: high-pressure water delivered through a specialised nozzle that cuts out and flushes away whatever is blocking the pipe.
When is an electric eel better than a jetter?
For small-bore internal lines — a basin or shower branch — an eel is quicker and gentler. For main sewers, stormwater lines, tree roots and grease, jetting wins because it removes the blockage completely instead of drilling a hole through it.
