When Do You Actually Need Hydro Jetting?

Published October 7, 2026 · Snake-It-Away Inc.

Hydro jetting is the most thorough way to clean a drain or sewer line, but not every clog needs it. It uses high-pressure water to scrub the pipe walls clean, which is overkill for a simple hair clog and exactly right for a line packed with grease or roots. Here is how to tell when you actually need it.

What hydro jetting does

A hydro jetter pushes water through a specialized nozzle at very high pressure, blasting away grease, scale, sludge, and roots and flushing them out of the line. Unlike a snake, which punches a hole through a clog, jetting cleans the full width of the pipe. If you are weighing the two methods, see hydro jetting vs. snaking.

Signs you need hydro jetting

• Clogs that keep coming back. If you have snaked the same drain more than once this year, the pipe walls are probably coated and the snake is only reopening a channel. Jetting clears the whole pipe.
• Grease buildup. Kitchen and restaurant lines cake with grease that a snake slides right through, which is why commercial kitchens need it most.
• Several slow drains at once. That points to buildup in the main line, not one fixture.
• Roots in the line. After roots are cut, jetting flushes out the debris and cleans the walls.
• Before a camera inspection or a home sale. A clean line gives a clear picture.

When a snake is enough

Not everything needs jetting. A single first-time clog in one fixture, a hair clog in a bathroom drain, or a toy a toddler flushed is usually a straightforward snake job. We will tell you honestly which one your situation calls for. No upsell.

How we decide

We do not guess, and we do not jet everything to pad the bill. Often we run a camera first so you can see what is in the line, then recommend snaking or jetting based on what is actually there. You see the same screen we do.

Residential and commercial

Jetting handles both a clogged home kitchen line and a restaurant's grease-packed main.
