Signs You Need Hydro Jet Drain Cleaning (Not Just a Snake)
A standard drain snake clears most household clogs. Hydro jetting is what you need when a snake can’t, or when the snake works but the problem keeps coming back. Look for these patterns:
- You’ve snaked the same drain twice in three months. The snake punches a hole through the buildup, water flows for a few weeks, then it closes back up. The line needs the walls scoured, not another hole.
- Slow drains in an older home with cast-iron pipes. Cast iron drains installed before 1980 — common in San Francisco, the older Peninsula neighborhoods, and most pre-war homes — develop interior scale and rust tubercles. Snaking doesn’t remove that. Jetting does.
- Restaurant or commercial kitchen drains backing up during service. Cooking grease coats the pipe walls within weeks of a snake-only clear. The line clears, you reopen, grease builds back to the same spot. Recurring hydro jetting is the only sustainable answer.
- Backup keeps recurring even after a “successful” clear. If you’ve had drain cleaning three times in a year and you’re searching again, the previous service didn’t actually clean the pipe. It cleared the immediate clog.
- Roots in the line. Tree roots intrude through joints and grow into a brushy mat that catches debris. Standard snake cables tear through soft roots but glance off larger ones. A jetter with a root-cutting nozzle slices through them.
- Sewer or drain odor that keeps coming back after cleaning. The smell is organic material decomposing on the pipe walls. A snake removes the blockage; only jetting removes the source.
- You’re prepping for CIPP lining or video inspection. Both require a clean pipe wall to work properly. Jetting is the prep step.
If you’re seeing one of these, call (415) 359-4588. We’ll ask what’s been done before and tell you honestly whether jetting is the right next step or whether you’re describing a structural problem that lining or replacement would solve.
Our Hydro Jet Drain Cleaning Services
Six ways we use the jetter, each for a different situation. Click any service below for full details.
Residential Hydro Jet Drain Cleaning
For homes where snaking has stopped working — recurring clogs, slow drains in pre-1980 cast-iron systems, branch lines that close up between services. We jet from the most accessible cleanout, work the line in both directions, and confirm full flow before we leave.
Commercial Hydro Jet Drain Cleaning
For multi-tenant buildings, offices, gyms, retail, and medical buildings. Higher fixture counts mean higher cumulative buildup, and snaking a riser doesn't address what's coating the pipe walls between floors. We work after-hours when needed and coordinate building access.
Restaurant & Commercial Kitchen Grease Line Jetting
For restaurants, bars, cafés, and commercial kitchens where grease load means a snake-only clear lasts weeks at best. We set a recurring jet schedule based on your kitchen volume, work during off-hours so service isn't disrupted, and document the work for health inspection records.
Root Intrusion Removal
For lines where roots have grown through joints — common with mature trees over the lateral path. We use a root-cutting nozzle to shear the roots back to the pipe wall, then jet the cuttings out. If the camera shows the joint is structurally compromised, we tell you and quote lining or replacement separately.
Scale & Mineral Buildup Removal
For older cast-iron and galvanized drains where decades of rust tubercles and mineral deposits have narrowed the interior diameter. A snake can't remove this — it just bounces off. Jetting with a rotating nozzle strips the scale off the pipe walls and restores full flow.
Hydro Jet + Camera Inspection Combo
For diagnostic work, real estate transactions, and any situation where you want documented proof that the line is clean and sound. We jet the line, then run a camera through it and record the footage. You get a clean pipe and a video file to keep.
How a Hydro Jet Drain Cleaning Call Works
You call, a real plumber answers
Call (415) 359-4588. A licensed plumber asks what’s been done before, what the recurring pattern looks like, and what kind of pipe is in the line. If we’re not sure hydro jet is the right answer, we say so and recommend a camera inspection first.
On-site assessment, written quote.
We arrive in your 2-hour window with a text when we’re on the way. We confirm the line we’ll be jetting, identify the cleanout we’ll work from, and write the price down before we set up the equipment. If we see anything during setup that changes the scope — a damaged cleanout, a hidden access issue — we stop and re-quote before continuing.
Jet the line, verify with camera, leave the work area clean.
We pull the hose through the line working both directions where access allows, then run a camera to confirm the walls are actually clean (not just the center of the pipe). You see the before-and-after footage. If the camera shows structural issues that jetting can’t fix, we document them and quote any next steps separately — no pressure to act on them today.

How Our Hydro Jet Drain Cleaning Pricing Works
Hydro jetting costs more than snaking. It should — different equipment, different setup time, and a result that actually lasts. But “hydro jetting costs $X” without seeing the line is the kind of quote that gets revised mid-job, which is exactly what we don’t do. Here’s the actual price structure.
Phone qualification first. We ask the line type, what’s been tried before, and whether there’s an accessible cleanout. From that, a licensed plumber can usually quote a range over the phone.
On-site assessment before setup. We confirm the cleanout, check the pipe material, and write the price down before the equipment comes off the truck.
Four things drive the price on any hydro jet job:
- Line length and access — a short residential branch line off an outside cleanout is the easy job; a 100-foot main line with no exterior cleanout is several hours of additional access work
- Pipe condition — heavily scaled cast iron takes longer to clean than a relatively clean line with a single grease blockage
- Nozzle work required — a standard penetrating nozzle for grease is one job; root cutting plus scale removal plus flushing is multi-stage work
- Whether camera verification is included — we recommend it on every job, but it’s optional and quoted separately so you can decide
Recurring service rates for restaurants and commercial accounts are lower per-visit than one-off calls. If you’re on a quarterly grease line schedule, we price the contract so the visits cost less than calling us when the line backs up during dinner service.
What you won’t pay for:
- A jetter setup fee added on after the quote
- An upsell to jet a line that snaking would have handled
- Pressure to fix structural problems the camera reveals — we document them, you decide
Call (415) 359-4588 with the line type and what’s been tried so far, and a licensed plumber can give you a range — no obligation.

Lateral Sewer Line Replacement FAQ
What is hydro jet drain cleaning, and how does it work?
Hydro jetting (also called hydrojetting or water jetting) uses pressurized water — typically 1,500 to 4,000 PSI — fed through a specialized nozzle on a flexible hose. The nozzle has forward jets that propel the hose through the line and backward jets that scour the pipe walls as the hose is pulled back. The result: grease, scale, roots, and buildup get sheared off the pipe wall and flushed out the cleanout. A snake bores a hole through a clog. A jetter cleans the entire pipe.
Hydro jetting vs. snaking — which one do I need?
Use a snake when: it’s a single clog in a single fixture, the line is otherwise clean, and the pipe is in good condition. Use a hydro jet when: the same drain has clogged repeatedly, the line carries grease (kitchen, restaurant, commercial), the pipe is old cast iron with scale buildup, there’s root intrusion, or you need to prep the line for CIPP lining or camera inspection. If you’re not sure which you need, call us — we’ll ask enough to tell you honestly, and we’ll recommend the cheaper option when it’ll actually solve the problem.
How much does hydro jet drain cleaning cost?
It depends on line length, access, and what we’re clearing. A short residential branch line jet with an accessible cleanout is at the lower end of the range. A long main line with heavy grease load or root intrusion is several times that. Commercial restaurant grease line service costs more per visit because of the equipment time, but recurring contract rates are substantially lower per visit than one-off calls. Call (415) 359-4588 and we’ll quote a range over the phone.
How much does it cost to jet a sewer line?
Sewer line jetting cost is driven by length (typical residential laterals run 40–100 feet), the cleanout access, and what’s in the line — grease and soft buildup come out faster than mature root masses or heavy scale. We quote sewer jetting in writing before we set up the equipment. If the line needs lining or replacement rather than jetting, see our lateral sewer line replacement page — we’ll tell you which during the call.
Is hydro jetting safe for old pipes?
In most cases, yes — but pipe condition matters. We adjust the PSI based on what we’re working in. Cast iron and clay pipes in good condition handle full pressure fine. Heavily corroded cast iron, damaged orangeburg, or thin galvanized steel can be at risk, which is why we recommend a camera inspection first on any older system where the pipe condition is unknown. If the camera shows the pipe is too compromised to jet safely, we’ll tell you before we start.
How often should I have hydro jetting done?
For most homes, never on a schedule — only when symptoms warrant it. Restaurants and commercial kitchens should jet quarterly because grease re-coats the pipe walls within weeks. Homes with mature trees over the sewer lateral benefit from annual jetting plus root cutting to keep ahead of intrusion. Older homes with cast-iron drains often benefit from a one-time deep clean when symptoms appear, then no recurring schedule needed.
Do you do commercial drain cleaning and sewer jetting for businesses?
Yes. Restaurants, bars, cafés, gyms, retail, multi-tenant residential, office buildings, and medical facilities. We schedule recurring grease line jetting for kitchens, after-hours work for retail and offices, and provide documentation for health inspections and lease compliance.
What's the difference between hydrojetting and sewer jetting?
Same equipment, different application. Hydrojetting (or hydro jetting) is the general term — it covers any high-pressure water cleaning of a drain or sewer line. “Sewer jetting” specifically refers to jetting the sewer lateral (the line from the house to the city main), versus jetting an interior branch drain. We do both.
Can hydro jetting fix a broken pipe or a pipe with roots?
Jetting removes roots that have grown into the line; it doesn’t repair the joint they grew in through. If the camera shows the pipe is structurally fine but full of roots, jetting plus a root-cutting nozzle handles it — and you may need annual maintenance jetting to stay ahead of regrowth. If the camera shows the joint is broken or the pipe is cracked, jetting clears the immediate problem but doesn’t fix the underlying cause. That’s a lining or replacement job — see our lateral sewer line replacement page.
Can I rent a hydro jetter and do this myself?
Small electric jetters are available at rental yards, but they top out around 1,500 PSI and 1.5 GPM — enough for a slow sink, not enough for a grease-coated kitchen line or root intrusion. Commercial jetters run 4,000 PSI at 8–18 GPM and require proper training to use safely (the nozzle can damage pipes if used wrong, and the hose can recoil violently if it slips out of the line under pressure). For a one-time line cleaning, calling a pro is cheaper than the rental plus the risk.
Do you offer same-day hydro jet service?
Same-day in most cases, Monday through Saturday, depending on whether we have a jetter truck in your area. Restaurant emergency calls during service hours get priority dispatch. Closed Sundays for non-emergency work. Call (415) 359-4588.
