High-pressure water jetting is the workhorse of modern drain cleaning. Here’s what it actually does, when it’s the right tool, and why it won’t harm a sound pipe.
What it is
Water jetting (also called hydro-jetting) uses water pumped at high pressure through a specialised nozzle. The nozzle drives forward through the line while jets aimed backward scour the pipe wall and flush debris downstream. It’s water doing the work — no blades grinding against the pipe.
What it clears
- Grease, fat and oil build-up.
- Sludge, silt and scale.
- Tree-root intrusion.
- General debris in mains, branch lines and surface drains.
Jetting vs manual rodding
Rodding pushes a path through a blockage — useful for a quick clear, but it often leaves the surrounding build-up in place, so the line narrows and blocks again. Jetting cleans the whole pipe wall and flushes the loosened material away, restoring closer to the pipe’s full bore. For recurring or grease-heavy blockages, that difference is the difference between a fix and a temporary patch.
When to use it
Jetting is the right call for blocked or slow mains and drains, grease-heavy F&B lines, root intrusion, and any line that keeps blocking. Where a blockage keeps returning, we pair jetting with a CCTV inspection to confirm there isn’t a structural fault behind it.
Is it safe for my pipes?
For pipes in sound condition, yes. Jetting uses water against build-up, and we match the pressure and nozzle to the line. The sensible precaution is with old or already-damaged pipes — which is why we inspect suspect lines first rather than jetting blind. A sound pipe handles jetting comfortably; a pipe that’s already failing needs assessing either way.
If a drain is slow, greasy or blocking repeatedly, jetting clears it properly rather than just poking a hole through. For older pipes, a quick check first keeps it safe.
