When hydro jetting is the right call
Chronic recurring clogs. If a cable auger cleared your kitchen line last month and you are already seeing slow drainage, the clog never really went away — the cable punched a hole through it and the pipe wall is still grease-caked. Jetting scours the whole wall. Twelve months of relief is typical after a proper residential jet; two to three years is possible on a line that gets occasional maintenance.
Commercial grease trap and FOG compliance work. Restaurants along Highland Ave and the Mile of Cars corridor have grease-trap pumping on 90-day cycles for health-department compliance (see our grease trap compliance guide). The lines between the trap and the city main need jetting too — grease that got past the trap, food debris, soap scum. Scheduled nighttime jetting keeps the kitchen open through dinner service.
Scaled cast-iron drains in pre-1970 homes. Interior scale in old cast iron effectively reduces a 2-inch pipe to a 1-inch pipe. A rotating chain-flail jet head mechanically removes scale, then a flushing head carries debris to the main. In some cases this buys 10-plus years before the pipe needs CIPP lining — see what cast-iron drains are really telling you.
Root cleanup after cable cutting. Cutting roots with a cable buys 6–24 months. Jetting after a cable job flushes the root fragments completely so the regrowth starts from zero.
When hydro jetting is NOT the right call
Orangeburg sewer laterals. The tar-paper pipe deforms and the walls are already weak. Jetting can breach it. If the camera shows Orangeburg, the honest answer is replacement — pipe burst or trench — not another jet. See what Orangeburg pipe is and why National City has so much of it.
Badly channeled cast iron. When the bottom third of the pipe has corroded through, the walls that remain are thin. We camera first for exactly this reason.
One-time fixture clogs that are not recurring. A hair clog in a shower drain is a cable or hand-auger job, not a jetter. We use the cheaper tool when it is the right one.
What our jetter trucks carry
- 3,000 PSI gas-powered jetter with 300-foot hose

- Root cutter heads
- Flushing nozzles for grease and sand
- Self-levelling sewer camera with sonde locator
