Hydro Jetting Services in Redwood City High-Pressure Drain & Sewer Cleaning
Grease, roots, and scale don't stand a chance — restore your pipes to full flow with professional hydro jetting on the Peninsula
What Is Hydro Jetting?
The most thorough drain cleaning method available — high-pressure water that scours pipes back to near-original condition
Hydro jetting sends water through your drain or sewer line at pressures up to 4,000 PSI using a specialized self-propelling nozzle. Forward jets cut through the blockage — packed grease, invasive tree roots, mineral scale, even construction debris — while rear-facing jets scrub the entire circumference of the pipe wall and push everything downstream to the city main. Where a standard drain cleaning with a cable machine opens a hole through a clog, hydro jetting removes the buildup itself.
That difference matters for Peninsula homes. Much of the housing stock in Redwood City, San Carlos, and San Mateo was built between the 1940s and 1970s with clay or cast iron sewer laterals. Decades of accumulation narrow these pipes year after year — a 4-inch line can be down to an effective 2 inches of flow before the first backup ever happens. Jetting restores that lost capacity instead of just postponing the next clog.
What Hydro Jetting Removes
- Hardened grease and soap buildup in kitchen and main lines
- Tree root intrusion from mature Peninsula landscaping
- Mineral scale and rust buildup inside old cast iron pipes
- Sludge, sand, and settled debris in low-slope sewer laterals
- Wipes, paper, and foreign-object blockages in commercial lines
Our Hydro Jetting Process
Camera first, jet second — we never blast water blindly through an unknown pipe
1. Sewer Camera Inspection
Every hydro jetting job starts with a camera inspection. We need to know the pipe material, its condition, and exactly what's blocking it. This protects your plumbing — jetting a pipe that's already cracked or collapsed can turn a cleaning job into an excavation. If the line isn't a candidate for jetting, we'll tell you before any work begins.
2. Pressure Selection for Your Pipes
We match jetting pressure and nozzle type to the job: root-cutting nozzles for invasive roots, penetrating nozzles for solid blockages, and flushing nozzles for grease and sludge. Older clay laterals get treated differently than modern ABS or a commercial cast iron main.
3. Full-Line Cleaning
Working from your sewer cleanout, the jetter nozzle travels the full length of the line — typically from the house connection to the city main — scouring the entire pipe wall, not just the clogged section.
4. Post-Jetting Camera Verification
We run the camera again after jetting so you can see the results yourself. If the cleaning reveals underlying damage — root entry points, cracks, offset joints — you'll see exactly where it is and we'll walk you through repair options like trenchless sewer replacement with real footage, not guesswork.
When Hydro Jetting Is the Right Choice
Hydro jetting shines in situations where cable snaking keeps failing. If you've had the same drain snaked two or three times in a year, the problem isn't the clog — it's the buildup the snake leaves behind. Recurring kitchen line clogs almost always mean accumulated grease coating the pipe; recurring main line backups in older neighborhoods usually mean roots that regrow through the same joints every season. Jetting removes the root mass and the grease layer entirely, which is why a jetted line typically stays clear for years instead of months.
For commercial kitchens in Redwood City, San Mateo, and the surrounding Peninsula, hydro jetting isn't just a fix — it's preventive maintenance. Restaurant drain lines collect grease faster than any residential system, and a mid-service backup can shut down your kitchen during the dinner rush. Our commercial plumbing clients schedule jetting on 6 or 12 month cycles through our maintenance programs, keeping lines clear and health inspections uneventful.
There are also times we'll steer you away from jetting. If the camera shows a collapsed pipe section, severe channeling in the pipe bottom, or Orangeburg pipe (a bituminous fiber pipe used in some mid-century Peninsula construction that deforms under pressure), cleaning won't solve the problem — and we'll say so. In those cases, sewer line repair or replacement is the honest recommendation.
Hydro Jetting FAQs
What is hydro jetting and how does it work?
Hydro jetting uses a specialized nozzle that blasts water at up to 4,000 PSI through your drain or sewer line. The forward-facing jets cut through blockages like grease, roots, and scale, while rear-facing jets scour the full diameter of the pipe wall and flush debris downstream to the sewer main. Unlike snaking, which punches a hole through a clog, hydro jetting restores the pipe to near its original capacity.
Is hydro jetting safe for old pipes in Peninsula homes?
It depends on the pipe's condition, which is why we always run a sewer camera inspection before jetting. Sound cast iron and clay pipes handle hydro jetting well, and we adjust pressure for the pipe material and age. If the camera reveals a badly cracked or collapsed section, we'll recommend repair instead of jetting — blasting water through a structurally failed pipe can make things worse.
How is hydro jetting different from drain snaking?
A drain snake bores a hole through the clog so water can drain again, but it leaves most of the grease, sludge, and root mass on the pipe walls — which is why snaked drains often clog again within months. Hydro jetting cleans the entire pipe diameter, removing the buildup itself. Snaking is the right call for simple, soft clogs; jetting is the right call for recurring clogs, grease, roots, and heavy scale.
How often should restaurants schedule hydro jetting?
Most Bay Area restaurants and commercial kitchens benefit from preventive hydro jetting every 6 to 12 months, depending on cooking volume and how much grease enters the drain system. Regular jetting prevents emergency backups during service hours and helps with grease ordinance compliance. We offer scheduled maintenance programs for commercial clients throughout the Peninsula.
How much does hydro jetting cost in the Bay Area?
Cost depends on the length of the line, severity of the buildup, and access. Residential hydro jetting typically costs more than basic snaking but less than repeated service calls for a clog that keeps returning. We provide upfront pricing after a camera inspection confirms what we're dealing with — call (650) 269-0190 for an estimate.
