Hydro-jetting is the high-pressure-water method for cleaning sewer pipe interiors of roots, scale, grease, and accumulated debris. A specialized nozzle is fed into the pipe at the cleanout; high-pressure water from a truck-mounted pump system jets backward against the nozzle, which scours the pipe walls clean as it is drawn back through the line.
We carry a truck-mounted hydro-jet trailer rated at 4,000 PSI and 18 GPM with a 200-gallon onboard water tank. The pressure is the cleaning force; the flow rate is what flushes the debris out of the line.
Hydro-jet vs. snake — which one do you need?
This is the most common diagnostic question we field. The short answer: a mechanical snake (K-7500 cable machine) is the right tool for a single stoppage. A hydro-jet is the right tool for chronic recurrence.
If your line backs up once and a rooter call clears it for 18 months, you needed a snake — and you got one. If your line backs up three times in a year, the roots are growing back into the same joints because the snake bores a hole through the root mass but doesn't remove it. Hydro-jet scours the roots out at the joint and pulls them out of the line entirely.
The same logic applies to grease. A snake punches through a grease blockage; a hydro-jet removes the grease coating from the pipe walls. For kitchen-stack grease problems, hydro-jet is always the right answer.
Our equipment + nozzles
The trailer is a truck-mounted Spartan 758 system at 4,000 PSI / 18 GPM. We carry three primary nozzle types, each for a different cleaning profile:
- Warthog (rotating-head root cutter)
- The aggressive root cutter. Spinning carbide-tipped head cuts root masses out of the pipe and pulls them down-line.
- Chain-knocker (chain-flailing scale cutter)
- For removing hard scale inside cast iron — the chain ends flail against the pipe interior, breaking off mineral buildup without damaging the pipe wall.
- Penetrator (forward-pointing high-pressure tip)
- For breaking through hard blockages (frozen grease, debris masses) before switching to the warthog or chain-knocker.
Process
A typical residential hydro-jet visit is 2 to 3 hours door-to-door.
- Step 1 — Pre-jet camera
- Camera inspection at the cleanout, identify the problem and its location.
- Step 2 — Nozzle selection
- Choose warthog (roots), chain-knocker (scale), or penetrator (debris) based on the camera.
- Step 3 — Hydro-jet pass
- Feed nozzle to the far end of the affected section, retract under pressure, repeat until camera confirms clean pipe.
- Step 4 — Post-jet camera
- Camera-verify clean pipe and identify any underlying issues the cleaning revealed.
- Step 5 — Recommendation
- Written scope of any underlying pipe conditions and whether replacement (trenchless or open-trench) should be scheduled.
What it costs
| Service | Includes | Cost |
|---|---|---|
| Standard hydro-jet | Pre + post camera, single nozzle | $485 – $740 |
| Heavy root + scale | Multiple nozzle passes, pre + post camera | $640 – $1,180 |
| Kitchen stack jet | 2"–3" line, specialized nozzle | $385 – $620 |
| After-hours emergency jet | +$185 dispatch over base | +$185 |
What hydro-jetting does NOT fix
Hydro-jet is a cleaning method. It does not fix the underlying pipe. Specifically, it does not fix:
- Pipe failure (collapsed, severely bellied, severely offset)
- Root intrusion through pipe-wall failures (it removes the roots but they grow back through the same failure)
- Pipe-grade problems (slope failures cause flow problems hydro-jet cannot fix)
- Orangeburg pipe failures (we do not hydro-jet Orangeburg)
For all of these, the answer is replacement — trenchless or open-trench. Hydro-jet may buy time; replacement is the fix.
