What Is Hydro Jet Drain Cleaning?

Hydro jet drain cleaning, sometimes called drain jetting, jet blasting or high-pressure water jetting, uses a purpose-built pump to force water through a nozzle at very high pressure, typically between 3000 and 4000 PSI, down through a flexible hose inserted into the pipe. The nozzle sprays water backward and forward as it's drawn through the line, which propels the hose forward while simultaneously cutting through blockages and stripping build-up off the pipe wall.

Repair vs Replacement: What Hydro Jetting Can and Can't Fix

Situation	Hydro Jet Drain Cleaning	Pipe Repair or Relining Needed
Tree roots grown into an otherwise sound pipe	Yes — clears roots and restores flow	Only if roots have cracked or displaced the joint
Grease, fat or soap scum build-up	Yes — hot water jetting dissolves and flushes it	No
Compacted silt or sludge after storms	Yes — cold water jetting clears it fully	No
Cracked pipe or damaged joint	No — jetting alone won't fix structural damage	Yes — pipe relining or section replacement required
Collapsed pipe section	No — jetting can worsen a collapsed line	Yes — excavation or relining required
Recurring blockage from ageing, brittle earthenware pipe	Temporary relief only	Long-term fix is relining or replacement

If the camera shows the pipe itself is damaged rather than just blocked, we’ll explain what’s going on and talk you through pipe relining or repair options before any further work goes ahead.

Cold Water vs Hot Water Drain Jetting

Method	Best For	Typical Use
Cold water jetting	Tree roots, silt, general debris, stormwater lines	Most residential sewer and stormwater blockages in Emerald
Hot water hydro jetting	Grease, fat, soap scum, trade waste	Commercial kitchens, cafés, food outlets, floor wastes

Cold water jetting handles the majority of domestic blockages efficiently, and setup is quicker on standard residential lines. Hot water hydro jetting is reserved for grease-heavy commercial lines where heat is needed to actually break the fat down rather than compress it further along the pipe.

When Hydro Jetting Is the Right Call

Recurring blockages

the same drain has blocked more than once in the past six to twelve months

Tree root intrusion

roots have entered the line through a cracked joint or aging earthenware pipe

Grease and fat build-up

kitchen drains, floor wastes or commercial grease traps that slow down repeatedly

Multiple slow fixtures

several sinks, showers or toilets draining slowly at the same time, pointing to a main line issue

Persistent bad odours

smells coming from drains that don't clear after a basic flush

Pre-purchase or pre-sale drain maintenance

clearing the system as part of preparing a property for sale or settlement

Post-storm debris

silt, grit and organic matter washed into stormwater or sewer lines after heavy Central Highlands rain

Equipment We Use

Nash Plumbing & Civil runs commercial-grade hydro jetting equipment capable of both cold and hot water jetting at pressures suited to residential and commercial pipe diameters. This is paired with drain camera equipment for pre- and post-jetting inspection, so every job is diagnosed and confirmed rather than guessed at. Using the right pressure and nozzle for the pipe material matters, particularly on Emerald’s mix of newer PVC and older earthenware and galvanised lines, where the wrong setting risks damaging an already-compromised pipe.

Warning Signs You Need Hydro Jet Drain Cleaning

Drains that gurgle or drain slowly even after a basic clear

The same fixture blocking again within a few months

Water backing up in a different fixture when you run another (for example, the shower backs up when the washing machine drains)

Persistent sewage or musty odours around drains or the yard

Visible tree root growth near sewer lines or a sunken patch of lawn above the pipe run

Slow-draining kitchen sink in a commercial setting despite regular cleaning

How Our Hydro Jet Drain Cleaning Process Works

CCTV Camera Inspection.

Before the jetter goes anywhere near the pipe, we run a drain camera through the line where the blockage cause isn't obvious. This confirms exactly what we're dealing with, root intrusion, grease, silt or a genuinely collapsed section, and tells us whether jetting is even appropriate. Jetting a pipe that's already cracked or collapsed can make the damage worse, so this step isn't optional on older or unknown lines.

Nozzle Selection and Pressure Setting.

We ask a few quick questions to understand severity and, where it's safe Different blockages need different nozzles. A root-cutting nozzle for tree intrusion is a different tool to a flushing nozzle used for grease or silt. Pipe diameter and material also affect the pressure setting we use, PVC, earthenware and older galvanised lines don't all take the same treatment.to do so, talk you through immediate steps like isolating your water or gas supply.

High-Pressure Water Jetting.

The hose is fed into the pipe and the jetter is engaged. High-pressure drain jetting cuts through the blockage while the reverse-facing jets scour the pipe wall clean as the hose is drawn back out. Cold water jetting handles most root intrusion, silt and general blockages. For heavy grease and fat build-up in kitchen lines, hot water hydro jetting is more effective, as heat breaks the fat down rather than just pushing it further along the pipe.

Post-Jetting Camera Check.

Once the line has been jetted, we run the camera through again to confirm the blockage is fully cleared and check the pipe condition downstream. This also flags anything that's likely to become a future problem, a cracked joint, a root entry point, or a section that's starting to sag, before it turns into another call-out.

Maintenance

Preventative Maintenance: How Often Should Drains Be Jetted?

How often should drains be hydro jetted?

For most residential properties on newer PVC pipework, hydro jetting isn't needed on a fixed schedule, it's used when a blockage occurs or recurs. For older properties with earthenware or galvanised lines, or homes with established trees near the sewer run, a preventative jet every twelve to twenty-four months keeps root growth and scale from building into a full blockage. Commercial kitchens producing consistent trade waste generally need hot water jetting every three to six months, depending on volume.

Scheduling a jet before it becomes an emergency call-out is almost always the cheaper option. A blocked drain that backs up into a home on a weekend costs more to fix than a booked maintenance jet on a weekday.

Frequently Asked Questions

Get A Quote

What causes a blocked drain that keeps coming back?

Recurring blockages are usually caused by tree roots growing into pipe joints, grease and scale build-up narrowing the pipe over time, or a structural issue like a sagging or partly collapsed section trapping debris. A CCTV inspection identifies which of these is happening before further work goes ahead.

Is hydro jetting safe for older pipes?

It depends on pipe condition. A sound earthenware, PVC or galvanised line handles high-pressure drain jetting without issue. If the pipe is already cracked, corroded or has a collapsed section, jetting can make the damage worse, which is why we run a camera inspection first on any older or unknown line.

How long does hydro jet drain cleaning take?

A standard residential job typically takes one to two hours, including the camera inspection before and after jetting. Longer pipe runs, severe root intrusion, or commercial grease trap lines can take longer.

Can hydro jetting fix a collapsed pipe?

No. Jetting clears blockages inside an otherwise intact pipe, it doesn’t repair structural damage. If the camera shows a collapsed or badly cracked section, pipe relining or section replacement is needed before the line can be jetted or returned to service.

How much does hydro jet drain cleaning cost?

Cost depends on pipe access, length of run, severity of the blockage and whether hot or cold water jetting is required. Residential jobs are generally more straightforward than commercial grease trap or trade waste lines. We provide a clear quote after assessing the job, before any work begins.

What's the difference between drain jetting and an electric eel?

An electric eel punches a channel through a blockage without removing the material coating the pipe. Hydro jetting physically strips the pipe wall clean and flushes the debris out of the system, which is why jetted lines generally stay clear for longer than lines cleared with an eel alone.

Do I need a camera inspection before jetting?

On any drain with an unknown or recurring blockage, yes. It confirms the cause, checks pipe condition, and avoids jetting a line that actually needs structural repair rather than clearing.
