How Long Does Hydro Jetting Take?

Setup and access take a few minutes; the jetting itself depends on how much buildup there is and how long the line is. A camera inspection before and after adds time but provides valuable confirmation. Commercial lines, being larger and often dirtier, generally take longer than a residential drain.

The biggest single variable is what's in the pipe. A line with light grease clears quickly; one packed with compacted grease, heavy scale, or a dense root mass takes longer because the nozzle has to make multiple passes to cut through and scour it all. Line length and diameter matter too — more pipe is more to clean — as does cleanout access: a convenient ground-level cleanout saves the time it takes to locate or reach a buried one.

A straightforward residential job — a sound line, reasonable buildup, an accessible cleanout — typically falls in that one-to-two-hour window including setup and a flow check. Commercial work runs longer as a rule: the lines are larger in diameter, often longer, and usually carry heavier grease or debris loads, and there may be multiple drains or a whole floor-drain system to service in one visit. None of that is wasted time — it reflects the real size of the job.

The technician will diagnose the problem, often run a camera, set up the jetter at the access point, clean the line, and verify flow. They'll explain what they found and recommend next steps before leaving.

You don't need to do much to prepare beyond providing access to the affected area or cleanout. The work is contained and clean — water and debris flush down the line to the sewer rather than into your space — and the technician should walk you through what the camera showed and what, if anything, the line needs going forward. If a structural issue turns up, that's the moment you'll hear about it honestly rather than after the fact.
