Quick Answer
Hydro jetting uses high-pressure water to scour the full inner wall of a commercial line clean — cutting through the grease, scale, and roots that cabling only pokes a hole in. For restaurant grease lines and commercial mains, scheduled jetting resets the pipe to full diameter and prevents the backup that closes a kitchen. Flat-rate.
Hydro jetting is the difference between clearing a drain and actually cleaning it. This page is part of our commercial plumbing coverage across West Los Angeles. A cable (snake) bores a hole through a blockage and restores flow — useful and fast — but it leaves the grease and scale coating the pipe wall, so the line clogs again soon. Jetting scours that wall back to bare pipe, which is why it is the standard for grease-heavy commercial lines.
Commercial hydro jetting is a drain-cleaning method that uses water at high pressure, delivered through a specialized nozzle, to scour grease, scale, sludge, and roots from the entire inner wall of a commercial pipe, restoring it to full flow capacity.
A jetting machine sends water through a nozzle that directs streams forward to cut the blockage and backward to pull the hose through and scour the walls. The forward jets break up the obstruction; the rear jets clean the pipe and flush the debris downstream. On a grease line, the result is a pipe returned to its full inside diameter rather than a narrow channel through a layer of grease — the same principle as residential hydro jetting, scaled to commercial demand.
We inspect commercial lines with a camera before jetting, for two reasons: to confirm jetting is the right tool and the pipe can take the pressure, and to rule out a structural problem — a crack, a belly, or a collapse — that jetting will not fix. We inspect again after to confirm the line is fully clear.
Restaurant grease lines are the classic case for jetting. Grease coats the full circumference of the pipe, and cabling through it leaves most of the buildup in place. Jetting scours it off, restoring full flow and resetting the maintenance clock.
We pair jetting with a sensible schedule — the interval depends on your volume — so the line never reaches the point of a service-hour backup. This is the core of preventive commercial drain maintenance.
Grease line slowing down? Jetting resets it to full flow.
Call (310) 663-7666Jetting is the answer for grease, scale, sludge, and root intrusion in a structurally sound pipe. It is not the answer for a cracked, collapsed, or badly bellied line — those need repair, and jetting a failing pipe can make it worse.
This is why we camera the line first. If the pipe is sound, we jet it clean. If it is failing, we show you the footage and discuss repair options plainly rather than jetting a line that needs replacing.
The Bottom Line
Cabling clears a path; jetting cleans the pipe. For grease-heavy commercial lines, scheduled hydro jetting scours the wall back to full diameter and prevents the backup that closes a kitchen. New Pro cameras the line first to confirm it is sound, jets it clean, and quotes flat-rate.
Snaking (cabling) bores a hole through a blockage and restores flow, but leaves grease and scale coating the pipe wall, so it clogs again soon. Hydro jetting scours the entire wall clean with high-pressure water, restoring the pipe to full diameter. For grease-heavy lines, jetting lasts far longer.
In a structurally sound pipe, yes — which is why we run a camera inspection first. Jetting is safe and effective for sound lines, but we will not jet a cracked, collapsed, or badly deteriorated pipe, because the pressure can worsen it. The camera tells us which situation we have.
It depends on volume and what the line carries. A high-volume kitchen may need jetting every few months; lighter use less often. We assess your line and set an interval that keeps it flowing without over-servicing. A camera inspection helps us gauge buildup rate.
Yes, jetting cuts through root intrusion and flushes it out. But roots return through whatever opening let them in, so for recurring root problems we identify the entry point on camera and discuss a lasting repair rather than repeat jetting alone.
We schedule jetting around your hours — early mornings, evenings, or closed days — so it does not interrupt service. The job itself is relatively quick for a typical line, and we confirm full flow with a camera before we leave.
Routine cabling handles occasional clogs and lighter lines. Jetting is for grease-heavy lines and recurring backups where buildup coats the pipe. If your commercial line clogs repeatedly, jetting addresses the cause rather than the symptom — we will advise which your situation calls for.
