Hydro Jetting of Sewers in San Francisco, CA
Clear Tough Sewer Buildup With High-Pressure Cleaning
A cable machine bores a channel through a grease blockage and leaves the rest of it clinging to the pipe wall, which is why the same line stops again within months. Hydro jetting takes a different approach, driving water through a nozzle at pressures measured in thousands of pounds per square inch to strip the wall clean. Malcolm Plumbing & Mechanical runs jetting equipment on restaurant lines, apartment stacks, and residential laterals throughout San Francisco, CA and the surrounding Peninsula.
Pressure alone is not the whole job. We size the nozzle to the pipe, check condition with a camera before jetting anything fragile, and confirm results with a second pass so you are not paying for an assumption. Our crews are licensed and insured, estimates are free, and labor carries a one-year warranty backed by 35+ years of work in this city. Tell us what the line is doing through our contact page and we will bring the right equipment.

Grease Line Jetting
Commercial kitchens build a hardened layer that no cable will touch. A degreasing nozzle drives water forward and back against the wall, lifting the deposit in sheets and flushing it downstream so the line recovers its original carrying capacity.
Root Cutting With Rotary Nozzles
Spinning heads throw water sideways at the pipe wall, shearing root hair and finer intrusion that mechanical cutters leave behind. The result is a cleaner cut surface, which slows regrowth compared with blades that tear rather than sever.
Main Sewer Line Jetting
Long runs accumulate sludge along the invert where flow is slowest. Jetting from a downstream cleanout pulls that material back toward the access point instead of pushing it further into the system, which is where most reblockages start.
Storm Drain and Area Drain Clearing
Leaf litter, silt, and gravel settle in area drains and stay there until the first real downpour finds them. Clearing these lines before winter keeps water moving away from foundations, light wells, and garage entries during heavy Bay Area rain.
Preventive Jetting Programs
Restaurants, laundries, and multi-unit buildings do better on a schedule than on emergency calls. Setting an interval based on how quickly your line loads up turns an unpredictable shutdown into a planned visit that happens outside business hours.
Post-Jetting Camera Verification
Clean water coming back is not proof of a clean pipe. A camera run afterward shows the wall condition, confirms full diameter, and reveals any defect the deposit was hiding, which turns a cleaning into useful information about the line.

FAQ's
What is the difference between hydro jetting and snaking?
Snaking bores an opening through the obstruction so flow resumes, while jetting washes the pipe wall down to bare material. One buys you time; the other resets the line. Heavy grease and repeat blockages usually call for the second approach.
Is hydro jetting safe for old pipes?
It can be, provided the pipe is inspected first and pressure is set to suit the material. Sound clay and cast iron handle jetting routinely. Lines already cracked or separated need repair before cleaning, which is what the camera pass determines.
How often should a commercial kitchen line be jetted?
Most busy kitchens land somewhere between quarterly and twice yearly, driven by menu, volume, and grease interceptor performance. Watching how fast the line reloads after the first cleaning gives a far better interval than any general rule of thumb.
Can hydro jetting remove tree roots completely?
Jetting clears the intrusion and cuts roots back to the pipe wall, but it cannot close the crack or joint that let them in. Roots return through the same opening, so lasting resolution means repairing or replacing that section eventually.
How long does a hydro jetting service take?
A straightforward residential line takes 1 to 2 hours including setup and camera verification. Long commercial runs, heavy grease, or multiple access points can push a job into half a day. Malcolm Plumbing & Mechanical schedules San Francisco, CA work realistically.
Does hydro jetting damage pipe joints?
Properly executed, no. Water is not abrasive at the wall in the way a steel cutter is, and correct nozzle selection keeps force distributed. Joints that fail during jetting were usually compromised beforehand, which the pre-inspection is designed to catch.
Will jetting fix a line that keeps backing up every month?
Monthly backups point to a structural problem rather than a cleaning problem. Jetting will restore flow, but a belly, an offset joint, or root intrusion will refill the line on the same schedule until the defect itself is addressed.
Do I need a camera inspection before hydro jetting?
For a first cleaning on an unfamiliar line, yes. Knowing the material, diameter, and condition prevents damage and sets the right pressure. Malcolm Plumbing & Mechanical inspects before jetting anything older across San Francisco, CA, backed by 35+ years of local pipe work.
Why Choose Us for Hydro Jetting of Sewers
Pipe Condition Checked First
Fragile clay and corroded cast iron do not always tolerate full pressure, and finding that out mid-job is expensive. Inspecting before we jet means the method gets adjusted to the pipe rather than the pipe absorbing whatever the machine delivers.
Equipment Matched to the Line
A nozzle sized for a 6-inch main wastes energy in a 2-inch kitchen branch and vice versa. Carrying a range of heads and pressure settings means the right tool goes down the right pipe on the first attempt.
Results You Can See on Screen
You are not asked to take our word for it. Footage before and after shows what came out and what the wall looks like now, which also gives you a baseline to compare against at the next service.
Fewer Repeat Visits
Restoring full diameter buys far more time than punching a channel through the middle of a blockage. Most buildings notice the difference in how long the line stays clear, which is the only measure of cleaning that actually matters.
Clean Site When We Leave
Jetting moves a great deal of unpleasant material, and containing it is part of the job rather than an afterthought. Access points get sealed, surfaces get washed down, and the space goes back to being usable before we drive away.
Scheduling Around Your Operation
Restaurants cannot lose a kitchen at 7 in the evening, and apartment buildings cannot lose a stack on a weekday morning. We book jetting for the hours that hurt least, including evenings and weekends where that works better.
Clean Pipe, Fewer Callbacks, Better Flow
Drain problems have a way of returning on their own schedule, usually at the least convenient hour, and the reason is almost always material left behind by a cleaning that only made an opening. Jetting removes what a cable cannot, and the camera footage afterward tells you honestly whether the pipe is sound or needs attention. Malcolm Plumbing & Mechanical brings both to buildings across San Francisco, CA, from single-family kitchens to restaurant grease lines and apartment stacks. Look at the evidence, decide at your own pace, and reach out through our contact page when you are ready to schedule.
