High-pressure water jetting
Scour, descale and
fully clear drains — without
chemicals or excavation
Up to 4,000 PSI of properly directed water clears fat, scale, roots and silt from domestic and commercial drains across Kent. The blockage doesn't just shift — the pipe gets cleaned.
What it covers
Properly specified water jetting — the right pressure, head and technique for the pipe
Water jetting is the single most effective tool for clearing and maintaining drainage. It uses pressurised water — not chemicals, not rods — to scour the full inside surface of a pipe, removing the material causing the blockage rather than punching a temporary channel through it. Done properly, jetting is the difference between three months and three years before the next call-out.
Our jetting fleet covers everything from a small domestic 50-litre trailer unit up to high-flow commercial rigs. Heads are selected for the job: rotating heads for fat, root-cutting heads for clay joints, descaling heads for old cast iron, and bullet heads for silt and leaf clearance in rainwater systems.
We use jetting both reactively — to clear an existing blockage on the day — and preventively as part of planned maintenance contracts for cafés, restaurants and care homes across Kent. Either way, every visit ends with a CCTV pass to confirm the pipe is fully clear and to flag any underlying defect for repair.
What happens if you wait
Skipping jetting now creates the blockage you'll be paying for in six months
Pipes that have only been rodded look clear on the outside but still carry a film of fat, scale or silt on the wall. That film catches the next wipe, the next root, the next piece of debris — and the call-out cycle starts again. Jetting actually cleans.
Rodded-only drains routinely re-block within months. Three call-outs at £150 each is rarely cheaper than one proper jetting visit.
Commercial kitchens that don't jet on schedule fail Environmental Health inspections, lose hygiene ratings and risk closure.
Allowed to build, fat and scale eventually crack pipes from the inside out — turning a maintenance issue into a £3,000 excavation.
Common mistakes we fix every week
- Using a garden-hose 'pressure washer' attachment that doesn't deliver the flow to scour anything.
- Jetting a pipe that CCTV hasn't been run through first — risks damaging an already-collapsed pipe.
- Choosing the wrong head for the material (bullet head on hardened fat, root-cutter on clean clay).
- Skipping the post-jet CCTV pass — you don't actually know the pipe is clear.
- Annual one-off jetting on a busy commercial kitchen instead of quarterly PPM.
- Buying a low-pressure DIY jetter and trying to clear an external main run with it.

-
STEP 01Phone triage
We confirm pipe material, location, access and history — and arrive with the right rig.
-
STEP 02Pre-jet inspection
Manhole inspection or short CCTV pass to ensure the pipe is safe to jet at pressure.
-
STEP 03Jet with correct head
Rotating, root-cutting, descaling or bullet head selected for the blockage and pipe.
-
STEP 04Verify on camera
Post-jet CCTV pass to confirm full clearance and identify any underlying defect.
-
STEP 05Report & guarantee
Written confirmation of work done, footage on request, workmanship guarantee in writing.
What you get
Concrete outcomes — not vague promises
Removes the cause, not just the symptom — pipes stay clear far longer than rodded-only work.
Safer for the pipe, the user and the environment than caustic unblockers.
Pressure and head selected to clean without damaging fragile clay or older cast iron.
Every job includes verification so you know the drain is actually clear.
Quarterly or six-monthly schedules tailored to commercial kitchens, care homes and retail.
Itemised reports for landlord, commercial and insurance records.
Technical detail
What good jetting actually looks like in practice
Jetting is one of those services where the kit, the technique and the operator matter as much as the pressure on the gauge. The difference between a properly cleaned drain and a 'cleared' one is real — and visible on camera.
Pressure vs flow — both matter
PSI is what most adverts quote, but flow rate (litres per minute) is what does the work. A 4,000 PSI machine at 15 litres per minute will clear blockages a 4,000 PSI / 8 lpm unit cannot. We pair pressure and flow to the job, not to the headline number.
Head selection
The same hose gets fitted with different heads depending on what's in the pipe — rotating heads for hardened fat, chain-flail and saw-tooth root cutters for clay joints, descaling heads for cast iron, and bullet heads for silt clearance on rainwater systems.
- Rotating heads — fat, grease and surface debris
- Root-cutting heads — clay-pipe joints and laterals
- Descaling heads — limescale in cast iron and copper
- Bullet heads — silt, leaves and free-flow debris
Safety and pipe protection
Jetting can damage cracked or partially collapsed pipes if used blind. We CCTV anything we're unsure of first, drop pressure on fragile runs, and refuse to jet pipes we know we'd cause further damage to — we'll quote a repair instead.
Planned preventative jetting for commercial sites
Restaurants, cafés, care homes and retail food units benefit hugely from scheduled jetting contracts. Typical schedules: quarterly for high-throughput kitchens, six-monthly for moderate use, annually for offices and light commercial. Records are kept for your EHO file.
Frequently asked
Straight answers to the questions Kent homeowners ask us most
How much does drain jetting cost?+
Standard domestic jetting is a fixed call-out fee including CCTV verification. Commercial jetting is priced per visit based on access and run length — we'll quote in advance after a brief survey.
Can high-pressure jetting damage my pipes?+
Not when used correctly. We adjust pressure for pipe material and condition, and we CCTV anything in doubt before jetting. We'll refuse to jet a pipe we know we'd damage further.
How often should commercial kitchens be jetted?+
Most high-throughput kitchens need quarterly jetting to stay compliant with EHO expectations. Moderate kitchens manage six-monthly. We tailor the schedule after a first visit.
Do you handle root cutting?+
Yes — root-cutting and saw-tooth heads on the jetter clear roots from clay-pipe joints, followed by a CCTV pass to confirm clearance and quote a permanent fix (typically patch lining).
Is jetting better than chemical unblockers?+
Almost always. Chemicals risk damaging seals, pipework and the user; jetting physically removes the material and cleans the pipe wall.
Will jetting clear a fully collapsed pipe?+
No — and we won't try. A collapsed pipe needs excavation or no-dig repair. Jetting is for blockages in structurally sound pipework.
Do you include a CCTV survey?+
Yes — a verification pass is included as standard on main-drain jetting. Full WRc-standard surveys with written reports are available as an add-on.
What areas do you cover for jetting?+
Kent, Medway, South-East London and the surrounding Home Counties for both reactive and PPM jetting.
