Signs You Need Hydro Jetting
- Multiple drains in the home slow down or back up around the same time
- A kitchen line that clogs repeatedly despite recent snaking
- A main line backup affecting several fixtures at once, especially lower-level drains
- Camera footage showing a heavy coating of grease or scale along the pipe walls
- A sewer lateral with a documented history of root intrusion
How jetting differs from cabling
Where a drain snake physically breaks through a blockage with a cable, a jetting nozzle sprays water at high pressure in multiple directions as it's pulled back through the pipe, scouring grease, sludge, and softer debris off the interior wall along the way. This makes jetting more thorough for a pipe with buildup spread across its length, such as a kitchen line that's accumulated grease over years, rather than a single discrete clog.
The trade-off is that jetting is a more forceful process, and it isn't the right tool for every situation. A small, localized clog in a bathroom trap doesn't usually need the scale of jetting, and a cable is often faster and sufficient for that kind of job.
When jetting isn't appropriate
High-pressure water isn't suitable for every pipe. Older, deteriorated clay or cast-iron lines, particularly ones already weakened by rust, cracking, or root intrusion, can be further damaged by jetting pressure that a sound pipe would handle without issue. This matters in parts of Bathurst Manor and Downsview where post-war clay laterals and aging cast-iron stacks are still common, and it's why a camera inspection beforehand is valuable: it lets us see the actual condition of the pipe rather than guessing.
Jetting also isn't a fix for a pipe with a structural problem like a collapsed section, a significant offset, or a belly holding standing water. In those cases the pressurized water can clear debris temporarily, but the underlying defect remains and the line will likely clog again.
Why a camera inspection often comes first
Before recommending jetting on a main or lateral line, we generally want a camera look at the pipe to check its material, joints, and general condition. This helps confirm whether the line can handle the pressure and lets us see exactly where root intrusion or scale buildup is concentrated, which is common near mature trees along streets in Don Mills and Parkwoods where roots enter through small cracks or joints in a lateral.
For condominium units near Yonge and Sheppard, backups sometimes originate in a shared stack rather than an individual suite's line, and a camera inspection helps determine whether jetting that section is realistic or whether the building's plumbing needs to be involved.
After jetting: what to expect
Once a line is jetted, flow is generally noticeably improved because buildup along the full wall has been cleared rather than just a channel through it. That said, jetting clears existing buildup; it doesn't change what goes down the drain afterward, so grease disposal habits and periodic maintenance still matter for kitchen lines in particular.
During spring melt or after heavy summer storms, lines that have had past root or grease issues can be more prone to renewed backups as extra water and debris move through the system, so it's worth keeping an eye on a jetted line during those periods, especially in the first season after service.
How We Handle It
- 1
Review the line's history and symptoms
We consider prior clogs, affected fixtures, and any past camera findings to judge whether jetting fits the problem.
- 2
Inspect the pipe with a camera when needed
For main or lateral lines especially, we check pipe material and condition before applying pressure.
- 3
Select pressure and nozzle for the pipe
Pressure and nozzle type are matched to the pipe's material and diameter rather than used at a single fixed setting.
- 4
Run the jetting hose through the line
The nozzle is advanced and pulled back through the pipe, scouring the walls as it goes.
- 5
Verify the result
We check flow afterward, and re-inspect with a camera if the line's condition was a concern going in.

Read our reviews on GoogleFrequently Asked Questions
Is hydro jetting safe for all pipes?
No. Sound, well-connected pipe generally handles jetting well, but older, cracked, or already-deteriorated clay or cast-iron pipe can be damaged further by the pressure, which is why we assess pipe condition first.
Do you always do a camera inspection before jetting?
For main or sewer lateral lines, a camera check beforehand is generally how we confirm the pipe can handle jetting and pinpoint where buildup or roots are concentrated.
When would you recommend snaking instead of jetting?
For a single localized clog, such as hair in a shower drain, snaking is usually faster and sufficient. Jetting is more suited to buildup spread along a longer run or a line with a recurring clog history.
Can jetting remove tree roots from a sewer line?
Jetting can cut through and clear softer, finer root growth, but larger or more established root masses may still need a mechanical cutting head, and the underlying crack or joint letting roots in isn't addressed by jetting alone.
Does jetting stop drains from clogging again in the future?
Jetting clears existing buildup thoroughly, but future buildup can still occur depending on what goes down the drain, so it works alongside habits like proper grease disposal rather than as a permanent one-time fix.
