Does your San Pedro building need hydro-jetting, or just a snaked drain?
Age explains a lot of the jetting calls in this part of town. Census figures for ZIP 90731 show a median build year of 1965, with 25.1% of housing units dating to before 1940. ZIP 90732 is younger, with a 1971 median. Clay sewer lines tend to run into trouble around 50 years, and roots love those joints. A cable punches a hole through a blockage. Water at 4,000+ PSI scours the pipe wall, which is the better choice when grease or roots keep returning. Figure $650 for a house.
Restaurants have an extra layer, as they do everywhere in LA. Under LAMC 64.30, a food service business discharging grease needs an Industrial Wastewater Permit from LA Sanitation. New kitchens need a grease interceptor, and so do remodels valued at $100,000 or more. Jetting doesn't replace any of that. It keeps the line behind the interceptor flowing, and we set kitchens on a quarterly schedule at about $950 a visit.
Skip the root killer sold at hardware stores. It's temporary and it damages the pipe. A camera look afterward tells you whether jetting solved the problem or the line itself has failed.
OUR PROCESS
How We Handle Hydro Jetting in San Pedro
Same crew, same factory-certified equipment, same property-friendly approach on every San Pedro job.
Camera pre-scope
Before we put 4,000 PSI through your line, we camera it to confirm the pipe can take the pressure. Severely deteriorated cast iron, collapsed sections, or root mats past a certain size need different methods first.
Match the nozzle to the job
Different jetting nozzles for different problems — penetrator heads for grease-clogged restaurant lines, chain-flail heads for scale and tuberculation, root-cutting heads for fine root intrusion. The wrong nozzle wastes time and water; the right one finishes in a single pass.
Jet and recover
We deploy the jetter from the cleanout downstream toward the city tap, then recover slowly while the rotating head scours the pipe wall. Debris is flushed forward into the sewer main where it belongs.
Camera verify & jetting schedule
Final camera pass documents pipe-wall recovery end-to-end. For commercial kitchens and recurring residential clogs, we set up a 6- or 12-month preventive jetting schedule — far cheaper than emergency response on a backed-up line.

“Hired Mainline for a Rinnai tankless install after getting quotes from three other companies. They were the most knowledgeable by far — explained the gas line sizing, venting requirements, everything. Install was clean and the unit runs perfectly. Worth every penny.”

“Hydro jetting service for our restaurant in Manhattan Beach. Grease buildup had our kitchen drain backing up every week. Mainline cleared the entire line and it's been flowing perfectly for 4 months now. They also set us up on a maintenance schedule. Very professional operation.”
