Drain jetting is a professional high-pressure water cleaning method that scours the full pipe interior rather than just punching through a blockage. It's the right choice for grease build-up, scale, silt and many root intrusions, especially where a blockage keeps coming back. It's not a repair technique, so a pipe in poor condition needs inspecting first to avoid making damage worse.
TL;DR:
- Drain jetting effectively removes grease, scale, sediment, roots, and soap scum, especially in recurring or stubborn blockages, by scouring the entire pipe interior.
- Proper nozzle selection and pressure control are crucial, with pressures typically between 1,500 and 4,000 psi, to avoid damaging fragile pipework.
- A CCTV inspection should precede jetting to identify cracks, root ingress, or collapsed sections, as high pressure can worsen existing damage.
- Jetting is less suitable for dislodging large, hard objects like toys or wet wipes and should be avoided on pipes with visible cracks or structural issues.
- Costs vary based on access and pipe condition, but fixed-price local services with upfront quotes are recommended over DIY attempts for safe, effective results.

What is drain jetting and how does it differ from snaking?
Drain jetting, also called hydro jetting or sewer jetting, fires a concentrated stream of water through a flexible hose down the length of a drain or sewer pipe. A cable auger, the tool most people picture when they think of drain "snaking," works differently: it pushes a rotating cable through the blockage and effectively punches a hole through it, leaving the rest of the pipe wall coated in whatever caused the clog in the first place.
Jetting instead scours the entire circumference of the pipe, restoring the full internal diameter rather than just clearing a channel through the middle.
Residential jetting equipment typically runs at 1,500 to 4,000 psi, with commercial rigs going considerably higher for larger mains. That pressure range is enough to strip grease films, break up scale deposits, and shred many root intrusions without needing to dig anything up.
- Cable auger: punches through, leaves residue on pipe walls, cheaper for a one-off soft blockage
- Drain jetting: scours the whole pipe, removes residue, better for recurring or stubborn build-up
- Combination cleaning: some jobs use both, auger first for access, jetter for the finish
How does drain jetting work: kit, hose and nozzles
A jetting rig has four main parts: a pump (petrol, diesel or electric depending on the job), a hose reel, a flexible high-pressure hose, and a set of interchangeable nozzles. The nozzle is where most of the skill sits. Rear-facing jets on the nozzle head propel the hose forward through the pipe almost like a small jet engine, while forward-facing jets blast directly into whatever is blocking the line.
Different nozzles suit different deposits. A flat or root-cutting nozzle chews through root mats and scale, an emulsifying nozzle breaks grease down so it flows away rather than re-solidifying further along the pipe, and a pulsing or rotating nozzle helps the hose negotiate bends without getting stuck.
Manufacturer specifications, such as those published for RIDGID's KJ-2200 water jetter, list working pressures, flow rates and compatible nozzles side by side, which is exactly the information a competent operator checks before starting.
Getting nozzle and pressure wrong isn't a minor error. Too aggressive a nozzle on a fragile pipe can widen an existing crack; too gentle a setting on heavy scale just wastes time and water.
- Pump and hose reel: sets maximum pressure and flow available on site
- Nozzle selection: determines whether the jet cuts, scours or emulsifies
- Pulse or rotating action: helps the hose travel round bends and junctions
- Accessory kit: foot valves and shorter wands for tight indoor access
Pro Tip: If a technician doesn't ask about the age or material of your pipework before jetting, that's worth questioning. Nozzle choice should change based on what's actually down there, not be a default setting.
What blockages does drain jetting clear?
Jetting earns its reputation on the deposits that snaking struggles with:
- Grease and fat build-up from kitchen waste, particularly in restaurant lines where it re-hardens along pipe walls.
- Soap residue and scum that narrows the bore of bathroom waste pipes over years.
- Silt and sediment that settles in low-flow sections of a drain run.
- Mineral scale from hard water, which cable augers tend to bounce off rather than remove.
- Root intrusions, where fine roots have worked into joints and spread through the pipe.
Jetting suits recurring blockages, commercial kitchen lines that clog on a predictable schedule, and long underground runs where a cable simply can't reach far enough. It's less suitable for a single hard object lodged in the pipe, such as a toy or a wad of wet wipes, and it should be avoided entirely on pipework with visible cracks or collapse.
Is drain jetting effective on damaged pipework, or too risky?
Jetting is a cleaning tool, not a repair method, and that distinction matters more than most guides admit. High pressure directed at a sound pipe scours it clean. Directed at a pipe with a hairline fracture, an open joint, or degraded Orangeburg pipe, the same pressure can wash out the surrounding bedding and turn a manageable defect into a collapse.
That's why a CCTV camera inspection before jetting has become standard practice rather than an optional extra. A camera scope run through the line lets an engineer check for cracks, root ingress at joints, bellied sections, or collapsed runs before any water pressure goes near them.
Red flags that should pause a jetting job include visible fractures, standing water suggesting a belly in the pipe, or any section where the camera footage shows daylight through the pipe wall. In those cases, the workflow shifts towards relining or spot repair instead. Around 1,500 to 4,000 psi is more than enough to worsen a defect that's already there, which is exactly why the inspection step exists.
- Camera scope first: identifies condition before any pressure is applied
- Watch for cracks, open joints, or root ingress at pipe junctions
- Bedding can wash out around a breached pipe wall under high pressure
- Alternative route for damaged pipe: relining or excavation, not jetting
What happens during a jetting service, and what does it cost?
A typical visit follows a fairly consistent sequence: assessment of the problem, access to the drain (usually through an existing manhole or rodding point), an optional CCTV pass if the pipe's condition is uncertain, the jetting itself using professional pressure cleaning techniques, then a flow check and sometimes a post-jet camera inspection to confirm the line is clear.
Duration depends heavily on access, how far the blockage sits along the run, and how severe it is. Straightforward residential jobs often complete within about 1 to 2 hours, while longer commercial runs or jobs needing a full survey either side can take longer.
- Assessment and access: locating the right entry point, usually 10 to 15 minutes
- Optional CCTV pass: adds time but avoids jetting into a damaged pipe blind
- Jetting itself: the bulk of the visit, typically under an hour for a standard blockage
- Flow check and sign-off: confirming the line runs clear before leaving
Cost varies by region, access difficulty, and whether a camera survey is bundled in, so treat any figure you see online as indicative rather than fixed. Restaurants and other high-use kitchen lines often benefit from scheduled jetting on an annual or biannual basis rather than waiting for a full blockage to develop.
Budget Rodz: how we approach drain jetting
A local drainage specialist carries out emergency drain unblocking, high-pressure jetting and CCTV drain surveys, typically arriving promptly after a call. Pricing is provided upfront, without unexpected extras once work begins.
Where a pipe's condition is uncertain, the same camera-first approach applies: a CCTV pass before jetting, correct nozzle selection for the deposit type, and a clear explanation of what's found rather than a guess.
When to call a professional versus trying it yourself
A domestic pressure washer won't reach far enough or scour a full pipe run, so persistent slow drainage, recurring smells, or a blockage that returns within weeks after a plunger fix all point towards calling someone in. Repeating a temporary fix on the same drain wastes money and delays the real answer. If you're unsure what's causing it, a CCTV survey settles the question before any pressure goes near the pipe.

FAQ
Can I jet my own drains?
Domestic pressure washers don't reach the pressure, flow or hose length needed to clear a full drain run, and using the wrong technique on an unknown pipe condition risks making things worse. Professional nozzle selection and pressure control are why this is best left to a technician.
How much does drain jetting cost?
Cost depends on access, run length and whether a CCTV survey is needed alongside the jetting, so figures vary by region and provider. Budget Rodz quotes a fixed price upfront before any work starts, so there are no surprises on the invoice.
Will a jet wash unblock a drain?
A domestic jet wash lacks the pressure, hose length and nozzle range of professional equipment, so it may shift a minor surface clog but won't clear grease, scale or root intrusion deep in a pipe run. Professional units running 1,500 to 4,000 psi are built specifically for that job.
Is sewer jetting worth it?
For recurring blockages caused by grease, scale or roots, jetting typically outperforms snaking because it scours the whole pipe rather than punching a single channel through the clog. It's not worth it, and can be risky, on pipework already showing cracks or structural damage, which is why a CCTV inspection beforehand matters.
