Jet blasting drains in Frankston
Updated November 2026
Jet blasting, also called hydro jetting, uses water at high pressure through a specialised nozzle to scour the inside of a drain. It cuts through tree roots, fat and grease, scale and sludge that a plunger or auger only pushes around. Frankston Blocked Drains connects you with licensed drain plumbers across the City of Frankston who carry jetting equipment.
We are a referral service. The plumbers we refer to are registered or licensed with the Building and Plumbing Commission.
How hydro jet drain cleaning works
The plumber feeds a hose into the drain through an inspection opening or gully. Rear-facing jets drive the nozzle forward while scouring the pipe walls, and a forward jet breaks up the blockage. Root-cutting heads are used where roots have entered at the joints. The debris flushes down the line.
Why Frankston drains need jet blasting
- Old clay pipes and mature trees: in Frankston North, Seaford and the older parts of Frankston, sewer lines laid in the 1950s and 1960s often have joints that roots can get into
- Grease build-up: kitchen lines in older houses and in units carry decades of fat
- Stormwater sediment: leaves, soil and sand washed into stormwater pipes after heavy rain
- Recurring blockages: a jet blast clears the full bore of the pipe, where a quick clear only punches a hole
Jet blasting and the camera
Jetting is often paired with a CCTV inspection. The camera shows what the jet needs to clear, and a second look afterwards confirms the line is clean and shows any damage the blockage was hiding. See CCTV drain camera.
When jetting is not enough
If the camera shows a cracked, collapsed or displaced pipe, jetting can clear the blockage but will not fix the pipe, and roots will come back through the same crack. In that case the options are a repair at the fault or pipe relining.
What jet blasting costs
As a guide, CCTV inspection plus jet blasting typically runs $350 to $900, and tree root clearing $250 to $600. Quotes vary with the length of the line and access, the plumber's written quote is the price that counts, and confirm GST on it. See the cost guide.
Whose pipe is it
If the blockage is on your side of the connection point, the work is yours. South East Water maintains the sewer up to the connection point with your property. If the camera shows the fault is in their main, report it to them.
Frequently asked questions
Will jet blasting damage my pipes?
In sound pipes, no. In badly cracked or collapsed pipes, the plumber will adjust pressure or recommend another approach. That is one reason to camera first.
How often should I jet my drains?
Only as often as needed. If a line needs jetting every year because of roots, relining may be cheaper over time.
Can jetting clear a blocked stormwater drain?
Yes. It is the standard way to flush sediment and leaves from stormwater pipes.
