Hydro Jetting: The Solution for SF's Scaled Pipes
San Francisco's cast iron sewer lines have accumulated 80-120 years of mineral scale, grease deposits, and root infiltration. This internal buildup doesn't just cause clogs — it permanently reduces pipe capacity until lines are either jetted clean or replaced. For homes in the Excelsior, Glen Park, and Bernal Heights where root intrusion is aggressive, hydro jetting offers lasting relief that mechanical snaking simply cannot match.
The city's combined sewer system adds another layer: stormwater deposits sand, silt, and debris inside your private lateral that wouldn't accumulate in a separated system. Annual or biannual jetting keeps these lines clear and functional between major maintenance events.
Hydro Jetting Applications in San Francisco
Why SF Pipes Need Jetting — Not Just Snaking
Decades of Internal Scale
SF's cast iron pipes develop thick tuberculation (rust scale) that snaking rides over without removing. Jetting strips it off the walls — restoring pipe diameter from as little as 2 inches back to the original 4 inches.
Aggressive Root Networks
Glen Park, Bernal Heights, and Noe Valley have mature trees whose roots infiltrate sewer joints. Snaking cuts a hole through roots; jetting removes the entire mass and scours the nutrients that attract regrowth.
Combined Sewer Sediment
SF's combined system deposits sand, grit, and storm debris in your lateral. This sediment compacts over time, reducing flow. Jetting flushes it completely — critical for flat-grade sections in the Sunset and Richmond.
Our Hydro Jetting Process
Pre-Jetting Camera Inspection
We assess pipe condition, identify weak spots, and confirm the line can handle jetting pressure. This protects fragile sections from damage.
Nozzle & Pressure Selection
Root-cutting, grease-dissolving, or scale-removing nozzles selected based on your specific blockage type. Pressure adjusted for pipe material and condition.
High-Pressure Cleaning
4000+ PSI water scours pipe walls from cleanout to main. Multiple passes ensure complete removal of all deposits, roots, and buildup.
Post-Jetting Verification
Camera confirms 100% flow restoration and documents pipe condition. We recommend a maintenance interval based on root activity and deposit rate.
