High-pressure water jetting is the gold-standard method for clearing significant drain blockages. The water pressure (1,500–4,000 PSI depending on pipe size and material) physically scours the inside of the pipe, removing fat-oil-grease deposits, limescale, root infiltration and accumulated debris that mechanical methods can't shift.
We operate twin-tank jetting rigs with 3,000–4,000 PSI capability and a full range of specialist nozzles, descaling rotary nozzles, root-cutting chain nozzles, and wash-down spray nozzles for post-jetting cleanup. Every jetting job is followed by CCTV verification to confirm the line is clear and identify any remaining structural defects.
Where this service applies
- Fat-oil-grease (FOG) build-up in domestic and commercial kitchens
- Limescale deposits in older clay drains
- Root infiltration (mechanically cut and flushed out)
- Sewage backup emergencies
- Pre-CCTV survey clearance
- Restaurant grease-trap maintenance
- Pre-relining preparation
- Storm-drain and surface-water blockages
