Drain jet blasting

Tree roots · Fat and grease · Scale build-up · Recurring blockages · Commercial lines

Cleans the pipe, rather than punching a hole through the blockage.

A jetter sends water down the drain at very high pressure through a nozzle that pulls itself along the line. It cuts roots, strips fat and scale off the pipe wall, and flushes the debris back out, which leaves the pipe closer to its original diameter.

Drain blocked now?
The short answer

Jet blasting, also called hydro jetting, clears and cleans drains using water at very high pressure rather than a mechanical cutting head. A hose with a specialised nozzle is fed into the line, and rearward-facing jets both propel it forward and scour the pipe wall as it goes. It is the most effective way to remove tree roots, hardened fat and scale, and unlike a drain machine it cleans the full diameter of the pipe instead of making a hole through the middle of the blockage.

When jetting is the right tool

Not every blockage needs a jetter, and we will tell you when a drain machine will do. Jetting earns its keep here:

Jetting is not the answer to everything. On a pipe that has already collapsed, water at pressure will not fix a structural problem, and we will say so rather than take your money for a temporary result.

How it works

How we jet a drain

1

We work out what is in the pipe

Roots, fat, scale, silt and concrete all want different nozzles and different pressures. Guessing wastes time and can damage an old pipe.

2

We set up at the access point

The jetter runs off the truck or a portable unit, and the hose goes in at the inspection opening or gully. We check where the water and debris will discharge before we start, not after.

3

The nozzle works its way up the line

Rear-facing jets drive the head forward and scour the pipe wall behind it. Debris is flushed back towards the access point rather than pushed further into the system.

4

We pull it back slowly

The cleaning happens on the way back as much as the way in. Rushing this is how you get a line that looks clear and blocks again next month.

5

Camera down it afterwards

We put a camera down to confirm the line is actually clean and to see the condition of the pipe now that it is visible. Sometimes that reveals a crack that the build-up was hiding.

6

We tell you what happens next

If the pipe is sound, a jet every year or two may be all it ever needs. If roots are getting in through a fault, jetting is buying time and relining is the actual fix. You get told which.

What jet blasting costs

Jetting sits above a straightforward drain machine clear and well below excavation. What moves the price:

For commercial kitchens and strata buildings, scheduled jetting on a set interval is almost always cheaper than emergency callouts, and it can be planned around trading hours.

Questions

Jet blasting questions

Not when the pressure and nozzle are matched to the pipe. That judgement is the skill in it. On a pipe that is already cracked or badly deteriorated, jetting can expose or worsen a fault that was being held together by the build-up around it, which is exactly why we camera the line and tell you what we find rather than pretending nothing happened.
An electric eel or drain machine is a rotating cable with a cutting head. It is mechanical, it is good at punching through a solid blockage, and it is often the fastest way to get water running again. A jetter uses water at pressure and cleans the full inside surface of the pipe. Simply put, the eel makes a hole through the problem and the jetter removes the problem. Both have their place and we carry both.
It cuts out the roots that are inside the pipe, back to the pipe wall. It does not kill the tree, and it does not stop roots growing back in through the same fault. If roots are getting in, there is a gap, and the permanent fix is to close the gap with relining or a repair. Jetting on a schedule is a legitimate alternative if you would rather manage it than fix it, and we will be honest with you about that choice.
If nothing is wrong with the pipe, never as routine. If you have a known root problem you are managing rather than repairing, every year or two is typical. Commercial kitchens are different and should be on a set schedule based on how much grease the line sees.
It is done every day on the old clay drains across the North Shore and the Hills, at appropriate pressure. The reason we camera afterwards is that old clay tells you a lot about its condition once it is clean, and it is better to know.
No. If a section has collapsed or crushed, there is no pipe left for water to travel through and no amount of pressure changes that. That needs excavation and replacement, or relining if enough of the host pipe remains. We will tell you which from the camera footage.
There is water and there is whatever came out of the drain. We plan the discharge point before we start, contain it, and hose and disinfect the area before we leave. That is part of the job, not an extra.

Jet blasting, drain machines, and knowing which one you need

Most people ring about a blocked drain and get whatever tool the plumber happens to carry. The two main options do different things and the difference matters for how long the result lasts.

The drain machine

A rotating steel cable with a cutting head on the end. It is fast, it is effective on a solid obstruction, and on a Sunday night with sewage rising in the gully it is often exactly the right call because the priority is getting water moving. What it does is clear a channel through the blockage. The build-up coating the inside of the pipe stays where it is.

The jetter

Water through a nozzle at high pressure, with the jets angled backwards so the head crawls up the pipe and scrubs the wall as it travels. It removes fat, scale, silt and root growth back to the pipe surface, so the line comes out closer to its designed diameter. That is why a jetted line stays clear longer than a snaked one, and why we jet before relining.

Why we camera after jetting, every time

A clean pipe is a pipe you can finally assess. Nine times out of ten that is good news and the line has plenty of life in it. Occasionally it shows a crack, an offset joint or a bellied section that the sludge was masking. That is not the jetter causing damage, it is the jetter revealing the reason the drain kept blocking. Either way you get to make the next decision with information instead of a guess.

Where we do most of it

Root cutting through the older suburbs, which means a lot of work in St Ives, Wahroonga, Turramurra, Killara and Pennant Hills where big established trees sit over old clay sewers. Fat and grease in kitchen lines, both residential and the cafés and restaurants we look after. Silt and sand in stormwater lines on the Northern Beaches. And preparation work ahead of relining anywhere.
