Sewer Jetting
Heavy-duty jetting for main lines, interceptors and commercial drainage - fatbergs, roots and scale cleared, with CCTV verification available.
Main sewer lines, large-diameter runs and interceptors are beyond what a domestic jetting kit can clean. Sewer jetting brings the water volume and pressure that scale of pipework needs: fatbergs cut apart, root masses sliced out with cutting nozzles, years of grease and scale stripped back to the pipe wall, and the debris flushed downstream and out of the system - not just pushed further along.

Where sewer jetting earns its keep
- Commercial kitchens and hospitality: FOG builds in main lines faster than anywhere else - we clear it, jet the traps and interceptors, and set up planned cycles that keep kitchens compliant.
- Interceptors and separators: petrol interceptors, silt traps and forecourt separators jetted and cleared on a planned cycle.
- Blocks of flats and managed sites: shared stacks and long private sewers where one blockage affects a dozen households.
- Victorian town-centre networks: the aged, high-capacity brick and clay sewers under Farnham and the surrounding town centres respond well to careful, calibrated jetting - and badly to brute force.
Calibrated, not just powerful
Pressure that clears a modern concrete main will strip mortar joints out of a Victorian brick sewer. Our engineers set pressure and nozzle choice to the pipe material and condition - root cutters, flail heads or standard penetrators as the job needs - and where the blockage keeps returning we follow with a CCTV survey to find the structural cause instead of booking the same emergency twice. For smaller domestic runs, see high pressure water jetting.
A main line down is a business down.

Frequently Asked Questions
Can jetting damage old sewer pipes?
Badly applied, yes - which is why pressure and nozzle choice are set to the pipe's material and condition. Calibrated jetting cleans Victorian brick and clay safely; brute force does not.
Do you offer planned maintenance contracts?
Yes - planned preventative maintenance (PPM) cycles for commercial kitchens, managed residential sites, and interceptor-equipped premises, with documentation after every visit.
How is sewer jetting different from ordinary drain jetting?
Water volume, pressure range and nozzle hardware sized for large-diameter mains and interceptors, rather than 100mm domestic runs. The technique is the same discipline at a different scale.
What if the same sewer keeps blocking?
A recurring blockage has a structural cause - a belly, scale, roots or a failing joint. We CCTV survey the line after clearing and quote the permanent fix from the footage.
