A main line that keeps backing up. A restaurant drain that clogs on grease mid-service. Roots you’ve had snaked twice already this year. Send a few details and one vetted, licensed San Francisco plumber gives you a straight read, not five companies fighting over your phone number.
Tell us how often it clogs, whether it’s a home or a commercial kitchen, and whether anyone has run a camera. That decides whether jetting is even the right tool here.
Hydro jetting clears a line with high-pressure water instead of a cable, often 3,000 to 4,000 psi through a nozzle that scours the full diameter of the pipe. It cuts grease, scale, and root mass off the wall and flushes the whole mess out, where a snake just punches a hole through the middle of the blockage. Two San Francisco situations make jetting the right call. One is the city’s wall-to-wall restaurant and cafe scene, where grease loads a kitchen or floor-drain line faster than any cable keeps up. The other is the old residential laterals, where roots and decades of scale in clay and cast iron close the line down until a snake stops being enough.
When to jet, when to snake, when to look first
| The line | Right first move | Why |
|---|---|---|
| Simple isolated clog, sound pipe | Cable it | Cheaper, and enough |
| Grease-loaded kitchen line | Jet it | Strips the wall; stays clear far longer |
| Root-choked lateral | Camera, then jet | Confirms the pipe can take pressure |
| Old cast iron, unknown condition | Camera first | Full pressure can split a corroded section |
| Repeat backups, no diagnosis yet | Camera | Tells you if it’s a clog or a break |
Jetting is powerful, and on a fragile old line that is exactly the risk. A cracked, thin, or badly corroded stretch of cast iron can be split by full pressure. So on any older San Francisco pipe the honest first step is a camera. It confirms the line can take the water and shows what is actually causing the backup: grease, roots, scale, or a structural break that jetting will never fix and only replacement will.
A plumber who jets an old cast-iron lateral before running a camera is guessing with your pipe. Sometimes the guess is fine. Sometimes a clog becomes a collapse and the bill goes from a few hundred dollars to a dig. Look first.
What a maintenance interval actually depends on
Grease-heavy kitchens usually come out ahead scheduling a jet rather than waiting for the backup that stops service on a Friday night. But the right interval is not a number off a chart. It depends on your volume, your menu (a fryer-heavy line loads faster than a salad place), the age and slope of your pipe, and whether the grease interceptor is sized and pumped on time. The way to set it: jet once, camera afterward, and watch how fast the wall re-coats. That tells you whether you’re on a quarterly line or a twice-a-year one.

San Francisco hydro jetting questions
Is jetting better than snaking?
For grease, scale, and heavy roots, yes. Jetting scours the whole pipe wall and the line stays open much longer, while a cable only opens a channel through the blockage. For a simple isolated clog a snake is often enough, and cheaper. What’s causing the backup decides it, which is why a camera pays for itself on a recurring problem.
Can jetting damage old San Francisco pipe?
It can, if the pipe is already compromised. Full pressure can finish off cracked or badly corroded cast iron. A camera first confirms the line is sound enough to jet.
Should my restaurant put it on a schedule?
Most grease-heavy kitchens should. A set interval keeps the line from loading up to a backup during a shift. Set it after a plumber sees how fast your line re-coats, not off a generic calendar.
