The symptom that suggests jetting
A line that drains for a few weeks and then slows again is telling you something. The cable made a channel through the blockage, but the buildup on the pipe wall stayed. Water now flows through a narrow tunnel, and the next heavy use closes it.
That pattern is common in kitchen lines with years of grease, in older cast iron with scale and in lines with a few fine roots. A camera shows which one it is. See drain cleaning for the cable side.
How the work is done
Camera first
The plumber looks inside the line to check its condition before using pressure on it.
Nozzle and hose
A jetting hose with a nozzle that sprays water backward and forward is fed down the line.
Scouring the wall
Pressure and flow strip grease, scale and soft roots off the pipe wall and flush them out.
Camera after
A second look confirms the pipe is clean and shows anything that was hiding behind the buildup.
Cable or jet: which tool fits
| Situation | Cable | Hydro jet |
|---|---|---|
| A one-time clog from a foreign object | Usually enough | More than needed |
| Grease buildup in a kitchen line | Opens a channel, buildup remains | Cleans the wall |
| Roots at a joint | Cuts them back for a time | Cuts and flushes, but the joint is still open |
| Scaled cast iron | May snag on rough scale | Strips loose scale, if the pipe is sound |
| Cracked, collapsed or very fragile pipe | Can make it worse | Not appropriate, repair the pipe first |
Who should not be jetted
Pressure is only a good idea in a sound pipe. A line that has cracks or fragile joints can be damaged by it, and a collapsed line cannot be cleared at all. That is why the camera comes first.
If the camera shows a break, the fix is sewer line repair, not more cleaning. Jetting a broken pipe only sends water and debris where it should not go.
Keeping the line clear afterward
A cleaned line stays clean longer when the cause is addressed. Kitchen grease goes in the trash, not down the drain. Wipes and paper towels do not belong in toilets. Lines in older homes may benefit from a periodic check, and the plumber can suggest a sensible interval.
What jetting costs depends on
- Line size and length, since longer and wider lines take more time.
- Access, because a cleanout makes the job faster than pulling a toilet.
- How heavy the buildup is.
- Whether a camera inspection is included before and after.
A plumber should give the price before work starts. If the camera shows damage that jetting could make worse, the right advice is to skip it, and a good plumber says so.
