Blocked drain pricing in Adelaide varies quite a bit, and most people get a quote before they understand why. A simple shower drain blockage and a root-infested sewer line are both called blocked drains, but they sit at opposite ends of the cost scale.
This guide breaks down what each method actually costs, what drives the price up, and what questions to ask before you book a plumber.
Quick Cost Summary
| Method | Typical Cost | Best For |
| Drain snake / hand auger | $80 to $250 | Surface clogs, hair, soap scum |
| Electric drain machine | $150 to $350 | Moderate blockages, kitchen grease |
| High-pressure hydro jet | $250 to $600 | Stubborn blockages, grease, scale |
| CCTV drain inspection | $150 to $400 | Diagnosing unknown blockages |
| Root cutting | $400 to $800 | Tree root intrusion in sewer line |
| Pipe relining | $800 to $3,000+ | Cracked or damaged pipe walls |
| Excavation and replacement | $2,000 to $8,000+ | Collapsed or severely damaged pipes |
Note: Prices are estimates based on standard Adelaide residential jobs as at 2026. Your job may sit above or below these ranges depending on access, depth, and the condition of the pipe.
What You Actually Pay For : Method by Method
Drain Snake or Hand Auger — $80 to $250
A drain snake is a flexible cable fed into the pipe to break up or pull out a blockage. It is the starting point for most straightforward jobs.
This method works well for hair clogs in shower drains, soap scum in basin drains, and minor kitchen sink blockages. It does not work for tree roots, collapsed pipes, or any blockage more than a few metres down the line.
If a plumber quotes a very low flat rate and sends a snake without inspecting first, ask whether a camera inspection is included. A cheap snake job that misses the actual problem will cost more in follow-up visits.
Electric Drain Machine — $150 to $350
An electric drain machine uses a motorised cable with cutting attachments. It reaches further and cuts through tougher material than a hand snake.
This is the standard tool for blocked kitchen drains, laundry drains, and moderate bathroom blockages. Most plumbing vans carry one as standard.
High-Pressure Hydro Jetting — $250 to $600
Hydro jetting uses a high-pressure water hose to blast material out of the pipe. It clears grease build-up, scale, and debris that a mechanical snake cannot shift.
It is more thorough than mechanical clearing the pipe walls get cleaned rather than just punctured. Plumbers often recommend it for recurring blockages that keep coming back, or for kitchen drain lines in commercial properties.
The higher end of that range applies to longer pipe runs, heavily scaled pipes, or jobs that require multiple passes.
CCTV Drain Inspection — $150 to $400
A camera inspection sends a small waterproof camera through the pipe on a cable. The plumber watches live footage on a monitor to locate the blockage, check pipe condition, and confirm the cause.
This is not always necessary for surface-level blockages, but it is the right call when:
- The same drain keeps blocking repeatedly
- Multiple drains are backing up at once
- There is a sewer smell you cannot locate
- The plumber cannot clear the blockage by mechanical means
- You are buying an older property and want to check pipe condition
Our Adelaide blocked drain plumbers carry CCTV cameras on every job where the cause is uncertain. Knowing what you are dealing with before you start work saves time and prevents guesswork.
Root Cutting — $400 to $800
Tree roots enter pipes through small cracks and joint gaps, then grow inside the pipe until water cannot pass. Root cutting uses a rotating blade to clear the root mass.
This is one of the most common causes of blocked sewer lines in Adelaide, particularly in older suburbs where large gum trees and Chinese elms are common. Clay and concrete pipes from the 1960s and 1970s are most vulnerable because the joints deteriorate over time.
Root cutting clears the blockage but does not fix the underlying pipe damage. If roots got in, water got in first, and the pipe has a crack or open joint. A CCTV inspection after root cutting will show whether the pipe wall is still intact.
Pipe Relining — $800 to $3,000+
If the camera shows the pipe wall is cracked, split, or deteriorating, relining is usually the most cost-effective repair. A resin-coated liner is inserted into the damaged pipe and inflated. It cures hard to form a new pipe inside the old one.
The cost depends on the diameter and length of the section being relined. Short runs in accessible locations sit at the lower end. Longer runs or pipes under concrete slabs cost more.
The alternative to relining is excavation, which is significantly more disruptive and usually more expensive when access is difficult.
Excavation and Pipe Replacement — $2,000 to $8,000+
When a pipe has collapsed, the section must be dug up and replaced. This is the most expensive option and is only necessary when relining is not feasible, such as when the pipe has completely caved in or shifted out of alignment.
Most licensed plumbers will recommend relining over excavation wherever possible. If you are quoted for excavation straight away without a camera inspection, ask why relining was not considered.
What Makes the Price Go Up
Several things push blocked drain costs higher than the baseline estimate:
| Factor | Effect on Cost |
| After-hours or weekend callout | Add $80 to $200 on top of standard rate |
| Difficult access (under slab, crawl space) | Extra labour time, higher total |
| Deep blockage in main sewer line | More equipment, more time |
| Tree root intrusion requiring camera + cutting | Both services combined |
| Recurring blockage (first visit missed the cause) | Second callout fee applies |
| Combined camera + jetting + report | Full diagnostic package, $400 to $700 |
No Call-Out Fee : What It Means
Some Adelaide plumbers advertise no call-out fee. This means the fee to attend your property is not charged separately, but the work itself is still priced by the job.
Same Day Trades charges no call-out fee. You pay for the work completed, not for the plumber turning up. All pricing is given upfront before work starts. For more on what Adelaide plumbing services include, see the full service page.
DIY vs Calling a Plumber : When It Makes Sense
For a slow-draining shower or basin, a $15 hand snake from Bunnings or a cup of boiling water with dish soap sometimes clears a surface hair clog. That is worth trying first.
Call a plumber when:
- Water is backing up into other fixtures when you drain one
- The blockage has not shifted after a basic DIY attempt
- You can hear gurgling from the toilet when the shower drains
- There is a smell coming from drains that does not clear
- The blockage keeps coming back within a few weeks
These are signs the problem is in a shared drain line or sewer main rather than at the surface. DIY tools cannot reach those locations and pushing a snake in the wrong direction can compact the blockage further.
How to Compare Quotes
When you get multiple quotes for blocked drain work in Adelaide, compare them on these points:
- Is the CCTV inspection included or quoted separately?
- Is there a call-out fee on top of the quoted rate?
- What method will be used and why?
- Is the plumber licensed? CBS licence number should be available on request
- What happens if the first method does not clear it — is there a follow-up charge?
A low upfront quote that adds camera inspection, call-out fees, and follow-up charges as extras can end up costing more than a higher all-inclusive quote.
Frequently Asked Questions
Is a blocked drain an emergency?
It depends. A slow drain is not an emergency. Sewage backing up into the house, sewer smell indoors, or multiple fixtures failing at once should be treated as urgent. Same Day Trades is available 24 hours a day for emergency blocked drain jobs across Adelaide.
Does insurance cover blocked drain clearing?
Standard home and contents insurance in Australia generally does not cover blockage clearing as it is considered a maintenance issue. However, if the blockage causes water damage to your property, that damage may be covered. Check your product disclosure statement or call your insurer directly.
How long does it take to clear a blocked drain?
A straightforward surface blockage takes 30 to 60 minutes. A blocked sewer line requiring camera inspection, root cutting, and a follow-up can take 2 to 4 hours. Pipe relining is usually a same-day job for short sections.
Can the same blockage come back after clearing?
Yes, if the cause was not fully resolved. Tree roots grow back within 12 to 18 months unless the pipe crack is sealed. Grease build-up recurs if the source is not changed. A CCTV inspection after clearing shows whether further work is needed.
