High-pressure water jetting clears a blocked drain in Magill more completely than an electric eel, because jetting scours the full pipe wall while an eel cuts a path through the middle of the blockage. An eel remains the right tool for a soft, one-off choke in a short internal line, and a plumber who carries both makes that call on site.
At Exceed Plumbing & Air Conditioning, we run both machines across Adelaide. This guide sets hydro jet drain cleaning against electric eel drain clearing using published manufacturer specifications: pressure, flow rate, cable diameter and reach. It also covers why a blockage returns, what a CCTV drain camera establishes that neither machine can, and which method suits a mature Magill property.
How an Electric Eel Clears a Drain
An electric eel clears a drain by spinning a steel cable fitted with a cutting head through the blockage, and the manufacturer’s own published specifications show exactly how that works:
RIDGID rates its RIDGID K-750 drum machine at 200 RPM, driven by a half-horsepower belt-driven induction motor. The drum carries 30.5 metres of 20 mm cable, or 35 metres of the thinner 16 mm cable.
The autofeed lever advances and retrieves that cable at up to 6 metres per minute, so the operator is not hand-feeding steel down a sewer. The cutting head at the end is interchangeable and sized to the pipe, from a 50 mm P-trap cutter up to a 150 mm double cutter.
RIDGID also matches cable to line size rather than leaving it to preference. The manufacturer recommends 16 mm cable for 75 to 150 mm drain lines, and 20 mm cable for 100 to 200 mm lines.
That last specification is the quick win for any homeowner: ask which cable and which cutter went down your drain. A plumber who can answer in millimetres is working to the manufacturer’s numbers, not guessing.
How High-Pressure Water Jetting Clears a Drain
Water jetting clears a drain with a hose that cuts roots using nothing but water, and the pressures Australian manufacturers publish for these machines are higher than most homeowners expect:
Australian Pump Industries rates its Aussie Cobra drain jetter at 4,000 PSI and 21 litres per minute, driven by a 20 horsepower twin-cylinder Honda petrol engine. The reel carries 60 metres of drain hose.
Adelaide supplier Clean Machine lists a B.A.R. 5027G-HEJMT petrol jetter at 5,000 PSI and 22 litres per minute, on a 27 horsepower Honda GX690, with 60 metres of drain hose and a 60 metre mini reel.
Pressure alone does not cut a root mass. Australian Pump Industries supplies a Turbo Root Mulcher that clears roots by, in its own words, vibrating and rotating, chopping off roots with a super high powered spinning water jet.
The nozzle does the work, and it changes with the job. Australian Pump Industries supplies a nozzle box of heads for clearing chokes in sewer lines and stormwater drains, and the debris is flushed away rather than left sitting on the pipe wall. That is the difference a homeowner notices weeks later.
Electric Eel and Water Jetting Compared
Set the two machines side by side and the differences are easy to check, with the reach figures below coming from jetter maker Australian Pump Industries rather than independent testing:
| Factor | Electric eel | Water jetting |
| How it clears | Cable spins a cutter through the blockage | Water at 4,000 to 5,000 PSI scours the wall |
| What it leaves | Buildup on the pipe wall | Debris flushed down the line |
| Reach | About 30 metres | Up to 120 metres from the vehicle |
| Tree roots | Cut at the blockage point | Chopped back by a root mulcher |
| Best suited to | Soft chokes and short internal runs | Grease, silt, roots, long external runs |
| Main limitation | Cable must match the line size | Pipe condition must be confirmed first |
Why the Blockage Keeps Coming Back
A drain that blocks again months after clearing was opened, not cleaned, and the reason usually sits in what SA Water lists first among the recorded causes of sewer blockages:
SA Water names the common causes of sewer blockages as tree roots, fat, oil or grease build-ups, foreign objects, and sewer line collapse. Tree roots come first on that list.
Roots do not sit in a drain as a single plug. On the jobs I attend they have grown in through a joint as a fibrous mass filling the bore, so a cutter that bores a channel through the middle leaves the rest anchored in the pipe.
Grease behaves the same way. A film left on the pipe wall keeps catching the next lot of paper, hair and food waste, so the second blocked drain often arrives faster than the first.
Magill gives roots plenty to work with. The suburb began as an 1838 foothills estate and was the first foothill village subdivided, so its 4,232 dwellings at the 2021 Census sit over long, established drain runs beneath mature gardens.
I see the same pattern on repeat callouts across the eastern foothills. The line was opened, flow returned for a season, and nobody established what the drain actually looked like.

Why the Camera Matters More Than the Machine
Two plumbers can clear the same drain and only one can tell you why it blocked, and the difference is whether a CCTV camera actually went down the line afterwards:
Unitywater, an Australian water utility, runs jet blasting and CCTV inspection as one combined maintenance program, specifically so it can clearly see any issues in the network it has just cleaned.
That is the logic a homeowner should borrow. Clearing restores flow, but flow tells you nothing about whether the cause was grease, a root mass through a joint, or a structural fault in the pipe itself.
The camera also settles the question of what the line can safely take. The Unitywater sewer rehabilitation program uses CCTV to identify damaged pipes before deciding on repair, and a pipe with a fracture or a collapsed section is a repair job, not a cleaning job.
Ask for the footage. A drain camera inspection should show you the same picture the plumber saw, at a stated distance from the access point, before and after clearing.
Clearing a collapsed pipe achieves nothing. If the camera shows a fracture or a joint that has dropped, the next conversation is about pipe relining, not another clean.

When an Electric Eel Is the Right Call
Bringing a petrol jetter to a blocked basin is overkill, and a plumber who owns both machines will tell you plainly where an eel is still the better first tool:
A soft blockage in a short run is eel work. A basin, a shower trap, a kitchen line to the gully or a toilet holding a foreign object is measured in metres of pipe, not tens.
An eel also retrieves. RIDGID supplies a retrieving auger in its standard tool set, which matters when the problem is a dropped object rather than a build-up that needs scouring.
Australian Pump Industries states that eel springs are difficult to manipulate and can damage pipes. That company manufactures and sells jetters, so it has a commercial interest in the comparison, and I have not found independent testing that settles it.
The safeguard is the manufacturer’s own specification. RIDGID sizes cable to line diameter, 16 mm for 75 to 150 mm lines and 20 mm for 100 to 200 mm lines, with cutters from 50 mm to 150 mm to match. Sized correctly to a short line, an eel is the proportionate call.
The Verdict for a Magill Drain
So which machine should turn up at your Magill property? For a third blockage in two years it is the jetter with a camera, and here is the full reasoning:
For a recurring blockage on an established Magill property, book high-pressure water jetting with a CCTV inspection as one job. Jetting removes the material an eel leaves on the wall, and the camera tells you whether roots, grease or a fracture put it there.
For a first-time, soft blockage in a short internal run, a basin, a trap or a single fixture, an electric eel clears it quickly and a jetter is the wrong tool for the size of the job.
Reach decides the borderline cases. Australian Pump Industries, an equipment manufacturer with a commercial stake in the answer, puts eel reach at about 30 metres against 120 metres from the vehicle for a jetter on a mini reel.
On a long run from the house to the boundary, that difference is the whole job. Ask which machine is coming, which nozzle or cutter it carries, and whether a camera goes down afterwards.

Frequently Asked Questions
What is the difference between an electric eel and hydro jetting?
An electric eel spins a steel cable with a cutter through the blockage. Hydro jetting instead uses water at 4,000 to 5,000 PSI to scour the full pipe wall clean.
Does hydro jetting damage pipes?
Pipe condition decides that, which is why the line should be inspected with a CCTV camera first. A fractured or collapsed section needs repair, not pressure, and the camera shows which it is.
Can an electric eel remove tree roots permanently?
No. A cutter clears roots at the blockage point, but roots re-enter through the same joint, so the line needs either regular clearing or a repair that seals the joint.
How far can a drain jetter reach?
Australian Pump Industries puts eel reach at about 30 metres and jetter reach at up to 120 metres from the vehicle. That manufacturer sells jetters, so the comparison is not independent testing.
Do I need a CCTV inspection after a drain is cleared?
Yes, if you want to know why it blocked. Unitywater, an Australian water utility, pairs jet blasting with CCTV inspection so it can clearly see any issues in the cleaned line.
