Drain Jetting in Newhaven
High-pressure water jetting is the standard way to clear and clean drains properly — it removes grease, scale and roots rather than just punching a hole through the blockage the way rods do.
What jetting costs
Domestic jetting typically runs £150–£400 depending on length, access and how heavy the build-up is. Commercial and tankered jetting is priced by the job.
What it will not fix
Jetting clears what is in the pipe; it cannot repair the pipe. If jetting keeps being needed on the same run, the money is better spent on a survey and a structural fix.
Van-pack or tanker — what you’re buying
A van-pack jetter handles almost all domestic work. Trailer and tanker units bring serious flow and recycling for long commercial runs and heavy grease — and their day rates to match. If a quote seems high for a house, ask which unit it assumes.
Keeping it clear afterwards
Jetting resets the pipe to clean; habits keep it there. Fat in the bin, strainers in plugs, the autumn gully clear — and where the survey showed rough old pipework, a planned re-jet beats an emergency one on price every time.
Two jetting myths corrected
Myth one: a pressure washer down the gully is basically jetting. It isn’t — jetting nozzles fire backwards, pulling the hose deep into the run and scouring toward you; a pressure washer only reaches the first metre. Myth two: jetting wrecks old pipes. Misapplied maximum pressure can damage a fragile run, which is precisely why professionals match pressure to pipe and why a pipe that cannot take appropriate jetting is already a repair case — the jetting reveals the problem rather than causing it. Both myths cost homeowners money in opposite directions.

Common questions
Is jetting safe for old pipes?
In competent hands, yes — pressure is matched to the pipe. A pipe that cannot take appropriate jetting is a pipe that already needs repair.
Jetting or rodding?
Rodding pushes through a soft blockage; jetting cleans the full bore. For grease, scale or roots, jetting is the one that lasts.
How often do commercial kitchens need it?
Food premises typically book planned jetting quarterly to twice-yearly depending on fat load — cheaper than one flood closure.
How long does a jet-clean last?
In a sound pipe with sensible use — years. Where scale or roots caused it, build-up returns from the day of the clean — the underlying defect needs repairing.
Can internal stack pipes be jetted?
Yes — smaller nozzles and lower flows exist exactly for stacks and internal wastes. Mention it in the post so the right kit arrives.
