Jet blasting and hydro jet drain cleaning in the Adelaide Hills

Updated October 2026

Jet blasting, also called hydro jetting or water jetting, clears blocked drains with high-pressure water instead of a mechanical cable. A jetting nozzle cuts through tree roots, scours grease off pipe walls and flushes silt and gravel out of the line. For most stubborn blockages in the Adelaide Hills, it is the tool that actually fixes the problem rather than poking a hole through it. Adelaide Hills Blocked Drains connects you with licensed local drain plumbers who run jetting equipment across the region.

How hydro jet drain cleaning works

A jetting unit pumps water through a hose at pressures of several thousand psi. The nozzle has rear-facing jets that pull the hose up the pipe and forward jets that break up the blockage. As the plumber draws the hose back, the jets scrub the full circumference of the pipe wall.

That is the key difference from an electric eel. An eel drills a hole through the middle of a blockage, which gets the water flowing but leaves roots and grease attached to the walls. The blockage rebuilds within months. Jetting cleans the pipe back to its original diameter, so a cleared line stays cleared for much longer.

Why Hills drains need jet blasting

The Hills give drains a hard time in a few specific ways:

Tree roots. Established oaks, elms, liquidambars and big natives send fine roots into any available moisture. In the older parts of Stirling, Aldgate, Hahndorf and Lobethal, clay waste pipes with aged joints are the usual entry point. Jetting with a root-cutting nozzle shears the roots off at the pipe wall.
Leaf litter and silt. Autumn packs stormwater lines with leaves, and every storm on a steep block washes soil, bark and gravel in behind them. Jetting flushes the lot through to the outlet, which hand-clearing a pit never quite does.
Grease and fat. Kitchen lines slowly coat with fat that narrows the pipe. Cafes, bakeries, cellar doors and pubs through Hahndorf, Stirling and Woodside see more of it than most, and on a septic property fat also shortens the working life of the tank.
Long, slow runs. Big blocks mean long pipe runs, sometimes with sections of very little fall. Anything that settles in a flat section stays there until something pushes it out.

What jet blasting costs in the Adelaide Hills

Costs vary by job. As a guide, clearing a standard blocked drain typically runs $150 to $400, with most jobs landing around $280. A jetting job combined with a CCTV camera inspection typically runs $350 to $900, depending on the length of pipe and how heavy the blockage is. Tree root clearing typically runs $250 to $600. If the camera shows the roots have broken the pipe itself, relining the damaged section typically costs $3,000 to $8,000 or more. Call-outs to the outer Hills may carry more travel.

The combined camera and jetting option is worth considering for any recurring blockage. The camera confirms what caused the blockage and proves the line is clean afterwards, so you are not paying for the same clear again in six months.

Jetting on a septic or CWMS property

Jetting works on the drain lines of an unsewered property the same way it does anywhere: the house drains, the line to the tank, and the outlet line beyond it. What it is not is a tank service. Jetting a pipe does nothing for a tank that is full of sludge, and pushing a large volume of water through into a tank that is already struggling is not helpful. A sensible plumber checks the tank first and jets second.

Pumping out a tank is a licensed liquid waste contractor's job with a tanker, and the plumbers referred through this site do not do it. If that is what the situation calls for, they will say so.

Jetting and your responsibility as the owner

SA Water owns the sewer mains in the sewered parts of the Hills, and you own the private drainage from your house to the connection point. On a council CWMS the shared line beyond your tank is the council's. On a full septic system all of it is yours. If jetting and a camera locate the fault beyond your connection, the plumber can tell you, and you can report it rather than pay for work on someone else's asset.

Is jetting safe for old pipes

Generally yes, in experienced hands. The licensed drain plumbers we work with adjust pressure and nozzle choice to suit the pipe. A badly cracked or collapsed pipe is a different story: no amount of cleaning fixes structural damage, which is why a camera inspection alongside jetting is standard practice. Given how much old clay pipe is still in service up here, that camera matters.

Frequently asked questions

How much does jet blasting cost in the Adelaide Hills?

A standard blocked drain clear typically runs $150 to $400, around $280 for most jobs. Combined CCTV and jetting typically runs $350 to $900. Costs vary with pipe length, access, travel and the severity of the blockage.

Is jet blasting better than an electric eel?

For most blockages, yes. An eel punches a hole through the blockage, while jetting cleans the full pipe wall, so roots and grease take much longer to return. An eel still has its place for some small lines and simple clears.

Can jet blasting remove tree roots?

Yes. A root-cutting jetting nozzle shears roots off at the pipe wall. If the roots have cracked or broken the pipe, jetting clears the line but the damage remains, and relining or replacement is the lasting fix.

Can you jet the drains if I am on a septic tank?

The drain lines, yes. The tank itself is not a jetting job, and if the tank is the real problem, clearing the pipe only buys a short reprieve. The plumber should check the tank before deciding.
