HIGH-PRESSURE WATER JETTING · TONBRIDGE · KENT

High-Pressure Water Jetting in Tonbridge and West Kent

Jetting scours the inside of the pipe rather than punching a hole through the blockage, which is why a jetted drain usually stays clear for longer. Used for grease, scale, silt, debris and fine root material in sound pipework.

What this service covers

High-pressure water jetting cleans a drain by forcing water through specialist nozzles at high pressure. The jets cut into the build-up and drag it back down the pipe towards the chamber, scouring the pipe wall as the hose is drawn back.

That distinction matters. Rodding a blockage can restore flow by making a channel through it, but the material lining the pipe stays where it is, so the drain narrows again. Jetting removes it, which is why it is the right tool when a drain keeps blocking in the same place.

It is not the right tool for every job, and a contractor who jets everything regardless of pipe condition will eventually make an expensive mess of somebody’s drainage. Where the pipe is fragile, displaced or collapsed, it needs a camera inspection first.

What jetting removes

  • Grease and fat. The single most common cause of recurring kitchen and commercial catering blockages, and the one jetting handles best.
  • Scale and hardened deposits. Kent sits on chalk, and hard water leaves mineral deposits that gradually narrow pipework.
  • Silt and sediment. Common in surface-water drains, soakaway connections and gullies that take run-off from unmade ground.
  • General debris. Wet wipes, sanitary products, building sand and leaf litter.
  • Fine root material. Root hairs and light ingress can be cut back where the pipe itself is sound. Heavy structural root damage needs repair, not repeat jetting.

When jetting is the right choice

  • A drain that has blocked more than once in the same place
  • Kitchen and catering waste runs with a history of fat build-up
  • Restoring flow capacity in a pipe that is running but running slowly
  • Cleaning a run before a CCTV survey so the camera can actually see the pipe wall
  • Preparing a pipe before relining or a resin patch repair, where the liner will not bond to a dirty surface
  • Scheduled cleaning on commercial premises as part of planned drain maintenance

How the work is carried out

  1. Assess the pipe first. Where the drain has a history of collapse, movement or fragile pipework, we inspect before jetting rather than after.
  2. Set up. The jetting unit needs vehicle access reasonably near the chamber and a water supply. We will confirm what is needed when we quote.
  3. Protect the working area. Jetting is wet work. Covers are lifted, the area around the chamber is protected, and we work with the discharge running away from the property.
  4. Jet the run. The correct nozzle for the deposit and pipe size is selected, and the hose is worked through the run and drawn back so material is pulled towards the chamber rather than pushed further along.
  5. Flush and flow test. The run is flushed and water is put through the system so restored flow can be seen.
  6. Clean down and report. The area is cleaned, and we tell you what came out and whether the pipe condition suggests anything further is needed.

Safe working and access

Jetting equipment operates at pressures that will cause serious injury if handled badly, so the working area is kept clear while the machine is running, and children and pets need to be kept indoors. We are CHAS accredited and SafeContractor approved, and our engineers are DBS-checked, which for a domestic customer simply means the safe-working side of this is documented and assessed rather than assumed.

Practically, the things that most often hold a jetting job up are parking, a locked side gate, and chambers that have been paved, decked or built over. Flagging any of those when you book saves time on the day.

When jetting is not appropriate

  • Collapsed pipework. Jetting a collapsed drain cannot restore it and risks worsening the damage. It needs repair.
  • Badly displaced or open joints. Water escapes at the defect instead of scouring the pipe, and the surrounding ground can be washed out.
  • Fragile or degraded pipework. Older pitch fibre pipe that has deformed, and some poorly bedded clay, will not tolerate full working pressure. Where we suspect this, we survey first and reduce pressure or recommend an alternative.
  • Heavy structural root ingress. Jetting cuts roots back, it does not stop them returning through the defect that let them in. Repeated jetting on a root-damaged joint is a maintenance bill, not a fix.
  • Internal soil and waste stacks inside a property. These need a different approach.

Unblocking or full cleaning?

These are different jobs and it is worth knowing which one you are buying. An unblocking visit is about restoring flow to a drain that has stopped, as quickly as reasonably possible. A full clean is about restoring the pipe to something close to its original bore along the whole run, so it takes longer and costs more, but on a drain with a history of build-up it is usually the cheaper option over a couple of years.

What you are left with

  • A drain run cleaned rather than simply punched through
  • A flow test you can see for yourself
  • An honest account of what came out and what it suggests
  • A recommendation on whether a survey or repair is worth considering
  • 12-month workmanship guarantee on the work carried out

Frequently asked questions

Not when it is used on sound pipework at an appropriate pressure with the right nozzle. The risk comes from jetting a pipe that is already fragile, displaced or collapsed, which is why we inspect first where there is any history of movement or damage rather than simply turning the pressure up.
It depends entirely on what is going into the drain. A domestic run cleared of a one-off obstruction may never block again. A kitchen run that regularly takes cooking fat will build up again, which is why some households and most commercial kitchens put jetting on a planned maintenance schedule instead of waiting for the next blockage.
The jetting unit carries water, but for larger runs an outside tap is useful. We will confirm what the job needs when we quote, along with where the vehicle needs to park.
It is wet work and there is no getting away from that, but it is contained. Covers are lifted, the area around the chamber is protected, and everything is cleaned down before we leave. Anything that comes out of the drain goes with us.
It can cut back root hairs and light ingress, and that will restore flow. It does not deal with the reason the roots got in, which is normally a cracked or open joint. If we find significant root ingress we will recommend a CCTV survey so you can decide about a patch repair or relining rather than jetting the same run every year.
Yes, and silt build-up in surface-water systems is one of the more common jetting jobs we do, particularly where run-off carries sediment from unmade ground or a driveway.
