Hydro-Jetting for Stubborn Drain Clogs
Hydro-jetting cleans a drain with high-pressure water instead of a cutting cable. A nozzle on a flexible hose scours the inside of the pipe wall and flushes out grease, scale, sludge and fine roots rather than just punching a hole through the blockage.

A cable is quick and cheap for a single clog. Jetting is the better tool when the same drain slows down every few months, when grease builds up in a kitchen line, or when a line needs to be spotless before a camera inspection or relining. A jetting pass leaves the pipe clean along its whole diameter, not just in the middle.
It is not a fix for a broken pipe. Jetting a cracked or collapsed line can make things worse, which is why a camera check often comes first or right after.
What the work includes
- A camera look at the line before and after the cleaning
- Access through a cleanout, roof vent or fixture connection
- Jetting with a nozzle chosen for grease, scale or roots
- Flushing of debris down to the main or the city connection
- A note on pipe condition, including any cracks or offsets seen
- Use of a root-cutting nozzle when roots are the cause
- Clean-up of the work area and any spilled water
- Advice on a maintenance schedule for restaurant or multi-unit lines
Drains that need more than a cable
A drain that clears for a few weeks and then slows again
Kitchen lines in a restaurant or apartment building that smell of grease
Several fixtures draining slowly at once, pointing to the main line
Gurgling from toilets or tubs when another fixture runs
Fine roots on a cable that comes back from the line
A line that must be cleaned before lining or a camera inspection
How the work goes, step by step
Find the access point
The plumber locates a cleanout or other opening large enough for the jetting hose.
Look inside first
A camera pass shows what is blocking the line and whether the pipe can handle jetting.
Choose the nozzle
A penetrating nozzle opens the line, a rotating one scours the walls and a cutting head deals with roots.
Jet in passes
The line is washed from the far end back toward the cleanout, with debris flushed to the main.
Check the result
A second camera pass confirms the line is clean and shows any damage that cleaning uncovered.
What changes the price
- Line length and diameter
- A long run or a wide main takes more water and time than a short branch.
- Type of build-up
- Fresh grease washes out quickly, while hardened scale and thick roots need slower passes.
- Access
- A clear cleanout keeps the job short, but a line with no access may need a toilet removed or a roof visit.
- Camera inspection
- Recording the line before and after is often a separate line on the quote.
- Commercial hours
- Restaurant kitchens and multi-unit buildings often need after-hours service.
- Emergency timing
- A backup on a weekend or at night costs more than a booked visit.
What a good quote spells out
- Which line is being cleaned and where the work starts
- Whether a camera inspection before and after is included
- The nozzle type and the water pressure that will be used
- What happens if the camera finds a cracked or collapsed section
- A suggested interval for repeat cleaning on commercial lines
Drain Cleaning & Hydro-Jetting: questions people ask
What is the difference between snaking and hydro-jetting?
A drain snake pushes a cable through a clog and clears a path. Hydro-jetting flushes the entire pipe wall with water, so it removes build-up that a snake leaves behind.
Can hydro-jetting damage old pipes?
It can, if the pipe is already cracked, collapsed or badly corroded. That is why a camera look usually comes before jetting an older line.
How often should a restaurant kitchen drain be jetted?
It depends on the volume of cooking and how well grease is trapped upstream. Many kitchens schedule it several times a year, and a plumber can set an interval after seeing the first camera pass.
Will jetting stop tree roots from coming back?
It cuts and flushes roots out of the line, but they return if the pipe still has a gap to grow into. Repeat cleaning or a repair of the joint is the longer fix.
