Main Sewer Line Jetting
Main sewer line jetting scours your home's primary drain line — the pipe carrying everything to the street — with high-pressure water, removing grease, sludge, scale, and roots along its full length. It restores capacity that snaking cannot. FlowFast connects you with an independent local plumber who can camera the line first and jet it properly.

Hydro Jetting Drain CleaningStubborn clogs that snaking can't clear? How hydro jetting works, when it's the right call, and how to get connected with an independent local plumber.
View all Hydro Jetting servicesEvery drain in your house funnels into one pipe: the main sewer line. When its interior narrows with grease, sludge, scale, or root intrusion, the symptoms hit everywhere at once — toilets bubble when the washer drains, showers fill while toilets flush, and the lowest fixtures threaten backup. Snaking the main clears a path through the blockage, but the coating on the walls remains, so the problem returns. Jetting is the reset button: it strips the line back to bare pipe wall along its entire run, from the house to the street.
Because the main line is the most critical pipe in the home, pros camera it before jetting to confirm it can handle the pressure — collapsed or badly broken sections need repair, not cleaning. Access is usually through a sewer cleanout; homes without one may need the pro to pull a toilet. FlowFast Plumbing is a referral service — we connect you with an independent local plumber who can inspect your main line, jet it wall-to-wall, and show you camera proof of the restored flow.
Warning signs
Signs you need this service
- Multiple fixtures misbehaving together — toilets gurgling when the washer drains, or showers backing up during flushes.
- Sewage odors from drains or cleanouts, signaling waste is lingering in a constricted main line.
- Backups that return weeks after a main-line snaking cleared them — the wall coating was never removed.
- A camera inspection showing the main line narrowed by grease, scale, sludge, or root intrusion along its length.
What to expect
The process, step by step
The pro cameras the main line to verify it is intact and to map the heaviest buildup and any root entries.
The jetting hose enters through a cleanout — or a pulled toilet if no cleanout exists — and works the full line length.
Rotating high-pressure jets scour walls clean while the flow flushes loosened debris downstream and out of the system.
A final camera pass confirms bare, clean pipe wall to wall, and the pro reviews the footage with you.
Prevention
How to avoid this problem
- If your home lacks a sewer cleanout, consider having one installed — it makes every future main-line service easier.
- Keep grease, wipes, and harsh chemicals out of drains to slow the buildup that chokes main lines.
- Schedule main-line jetting on a sensible interval if roots or grease have been repeat offenders.
