Common issues we fix
- Recurring blockages and slow-draining fixtures
- Bad odours and trapped wastewater
- Blocked external drains and gullies
- Emergency overflows and backups
In short: High-pressure drain jetting clears blockages and cleans the full pipe wall using water pumped at up to 4,000 PSI. Pressure, nozzle, and water temperature are all matched to the pipe material and the deposit being removed — hot water for grease-heavy commercial kitchen lines, cold water for general domestic clearance. A rotary root-cutting head is used where tree roots have entered the pipe, without excavation. No call-out fee — request a fixed-price quote online.
Pressure, and hot vs cold water
Our jetting units run at pressures up to 4,000 PSI, with the exact setting chosen for your pipe's material, diameter, and condition — older clay pipes are jetted at lower pressure than modern plastic, which can safely take a more thorough clean. For water temperature, cold water is used for most domestic clearance and general maintenance jetting, while hot water is reserved for grease-heavy lines — typically commercial kitchen waste — because heat melts solidified fat that cold water alone won't shift. We select the nozzle to match: a penetrating nozzle to cut through a blockage first, then a rotating cleaning nozzle to scour the full pipe wall on the way back.
Root cutting
Where a CCTV check shows tree roots have entered a joint or crack, we fit a rotary root-cutting head to the jetting hose. This mechanically cuts the roots back to the pipe wall while the jetting action flushes the cut material through to the sewer connection. Root cutting is carried out as part of a jetting visit rather than sold as a separate service — it isn't a permanent fix on its own if the entry point stays damaged, so where root ingress is heavy or recurring we'll also recommend a CCTV survey to check whether the joint needs relining afterwards.
Pricing
The cost of drain jetting depends on the length of pipe involved, whether hot water and specialist nozzles such as a root cutter are needed, and how much buildup has to be removed. Request a fast, fixed-price quote online — we confirm the price before starting and there is no call-out fee.

Our process
Assess the pipe
We check pipe material, diameter, and condition to select the right pressure and nozzle for a safe, effective clean.
High-pressure clean
Water is delivered at up to 4,000 PSI through a rotating nozzle, scouring the pipe walls and flushing debris towards the sewer connection.
Verify
A flow test — and camera check where included — confirms the pipe is genuinely clear, not just temporarily flowing.
