A cable pokes a hole. Jetting cleans the whole pipe.
In a city with houses this established, drains have been on the job a long time, and a lot of them are overdue for more than another snaking. Here's the pattern you might recognize. Drain clogs, plumber snakes it, everything's fine, then a few months later it's slow again. That's not a scam and it's not bad work. A snake punches a hole through the clog, but the years of grease, soap, and buildup coating the pipe stay right where they are, and they close the hole back up on schedule.
Hydro jetting breaks the cycle. A high pressure stream of water power washes the inside of the pipe, wall to wall, the entire run, and carries the buildup out of the line for good. Same idea as power washing a driveway instead of sweeping a path through the dirt. When it's done, the pipe is about as close to new inside as old pipe gets, and the clog stops coming back because there's nothing left for it to rebuild on.
Not every drain needs it, and nobody here will tell you otherwise just to run the machine. Sometimes a snake truly is the whole fix. The technician looks at your actual line, gives you the straight read, and recommends what makes sense. You decide. That's the whole process.
"Two other plumbers cabled it and it came back both times. Pipe Patrol jetted it and it's been clear ever since. Worth every dollar."
