A cable snake pushes or drills through a blockage, opening a channel roughly the width of the cable head, which is often enough for a single, isolated clog. Hydro jetting uses a hose with a specialized nozzle to spray water at high pressure in every direction, scouring grease, soap buildup, and lighter root intrusion off the entire inner wall of the pipe, not just punching a hole through the middle of it. That’s the reason a line that keeps clogging every few weeks after repeated snaking often stops clogging after one proper jetting.
It isn’t the right first step for every clog. A single, simple blockage usually doesn’t need it, and we’ll say so rather than recommend the bigger job by default. We check the pipe’s material and condition with a camera before jetting anything, so the water pressure used matches what the line can actually take, and an older or already-compromised section gets a different approach entirely.
