The two main tools for a blocked line get talked about as rivals. They’re not — they’re different answers to different questions, and knowing which question you’re asking saves real money.
What a snake does
A cable machine — the snake, the rooter — drives a rotating steel cable with a cutting head through the blockage. It’s fast, it works through modest access, and when water is rising it is exactly the right tool: flow is restored in minutes.
Its limit is geometry. The cable bores a passage through the clog, roughly the diameter of the head. Everything it didn’t touch — the grease lining the walls, the root mat around the passage — stays behind. The line drains today, and the leftover buildup becomes the scaffold the next clog grows on. That’s why the same drain can need snaking again months later: the tool did its job, but its job was a tunnel, not a cleaning.
What jetting does
Hydro jetting sends a nozzle down the line on a high-pressure hose — water at thousands of PSI, jetting backward against the pipe wall as the nozzle pulls itself forward. It doesn’t bore a hole; it strips the pipe’s full circumference back to bare wall. Grease emulsifies, scale flakes off, root material cuts away and flushes downstream out of the line.
The practical difference shows up in the calendar. A jetted line stays clear until buildup starts again from zero — not from ninety percent done. For kitchen lines with decades of grease or laterals with chronic root fuzz, that difference is measured in years, not weeks.
So which one?
Snake first when: water is actively backing up and speed matters; the blockage is likely a one-off (an object, a paper clog); budget is tight and the line has no repeat history.
Jet when: the same line keeps clogging; the camera shows wall buildup — grease, scale, root fuzz — rather than a single obstruction; you’re maintaining a commercial kitchen line, where cabling simply cannot keep up.
Neither, yet, when: nobody has looked inside. Jetting a badly cracked pipe is the wrong kind of pressure in the wrong place, which is why a camera check comes first on any line without recent footage. The pipe’s condition — not the tool on the truck — should pick the method.
The honest summary: a snake answers an emergency, jetting resets a pipe, and a camera tells you which one you’re actually buying.
