Why grease keeps coming back
Grease is the most common cause of sewer blockages: the EPA puts it at 47 percent of reported blockages. It coats the pipe wall, hardens, and catches everything that comes down behind it. A snake opens a channel through the middle and leaves the rest stuck to the wall, which is why the same line can back up again.
The camera capture on this page was taken 16 feet 8 inches into a line on May 10, 2025. That is what buildup looks like from the inside, and it is what the jetter is for.
How the water does the work
Two numbers matter on a jetter. Pressure, in PSI, cuts: one manufacturer’s guide puts residential roots and grease-packed restaurant lines at about 4,000 PSI. Flow, in gallons per minute, carries whatever the nozzle cuts loose down to the main instead of leaving it to settle. Our commercial-grade jetter is built for both house laterals and commercial lines, and we make several passes until the camera shows clean pipe.
Jetting for commercial kitchens and carwashes
Restaurants and commercial kitchens, heavy residential buildup, root intrusion and long-term preventive cleaning are what jetting is for. One carwash operator has brought us in as a subcontractor on its drain lines more than once:
We have subcontracted their services to hydro jet drain lines in the Carwash industry several times. They have the equipment and knowledge to get any job in the sewer world done correctly.
