The two methods
- Snaking (cabling)
- A motor spins a flexible steel cable with a cutting or retrieving head through the pipe to break up or pull out the blockage.
- Hydro jetting
- A hose with a specialized nozzle sprays high-pressure water forward and backward, scouring the pipe wall and pushing debris downstream.
- Cutting head
- The attachment on a cable, sized to the pipe; root cutters have blades, others are spirals or spades.
- Jetter nozzle
- Directs water jets; rear-facing jets pull the hose forward while cleaning.
Side by side
| Question | Cable | Jetting |
|---|---|---|
| Opens a fully blocked line | Yes, usually the first tool used | Can, though it often follows a cable |
| Removes grease coating | Partly | Thoroughly |
| Handles roots | Cuts through them | Cuts fine roots and flushes debris |
| Cleans scale in cast iron | Limited | Better, with the right nozzle |
| Safe on damaged pipe | Generally, with care | Can worsen cracks or loose joints |
| Leaves the pipe wall clean | No | Mostly |
Why pipe condition decides it
Jetting works by force. In sound pipe that is exactly what you want, because it removes the buildup that makes clogs return. In a clay lateral with a broken joint or a cast-iron line that has rotted thin along the bottom, the same force can wash out soil, enlarge a crack or break off a fragment. That is why many plumbers run a camera before jetting an older line, or open the line with a cable first and then look.
Cabling is less thorough but more forgiving. For a single recent clog in a fixture branch, it is usually all that is needed. For a line with years of grease, scale or roots, jetting may give a longer-lasting result if the pipe can take it.
Which one fits
- IfA single fixture or branch clogged for the first timeA cable is usually enough.
- IfA kitchen line with heavy grease that keeps returningJetting is worth discussing.
- IfRoots in an older clay lateralCable first, camera next, then decide on jetting or repair.
- IfCamera shows cracks, offsets or collapseAvoid aggressive jetting; talk about repair.
Questions to ask
- Why do you recommend this method for my line?
- Will you camera the line before jetting it?
- What pressure and nozzle will you use on older pipe?
- Where will you access the line, and will anything need to be removed?
Common questions
Is jetting safe for my house?
On pipe in good condition, yes, when done by a trained operator. On damaged pipe it carries more risk, which is why a camera check matters.
Does jetting prevent future clogs?
It removes buildup that causes clogs, so it can extend the time between problems. It cannot fix a sag, a broken joint or the gap roots came through.
Can jetting be done inside the house?
It is usually done from an outdoor cleanout so the water and debris flow toward the street.
