Stormwater Drains Sydney
Clear the channel before the next downpour — pits, pipes and surface drains flushed and inspected.
Stormwater systems clog with leaf litter, silt and debris. We clear pits and pipes with the jetter, flush the run to the legal point of discharge, and CCTV the line to confirm it's free-flowing before the next storm.

Not sure this is the problem?
If you're not certain, scan it first. A photo of the drain, gully or overflow is usually enough for us to tell you what's actually going on, which service fixes it, and what that costs fixed.

How a blocked drain is cleared
Clearing the blockage is only half the job. Every drain clear includes a camera inspection, because a drain that blocks once will block again unless you know why. This is what happens on a standard visit.
- 1
Find the access point
Usually the overflow relief gully (the grated outlet near an outside wall) or an inspection opening. This avoids pulling fixtures apart inside the house.
- 2
Work out where the blockage is
Which fixtures are affected tells the plumber whether it's a single branch (sink, shower) or the main sewer line (everything backing up).
- 3
Clear it with the right tool
A hand or powered auger for fixture traps and toilets. A high-pressure water jetter for the main line: it cuts through tree roots and scours grease and silt off the pipe wall instead of punching a hole through it.
- 4
Camera the line
A CCTV camera goes through the cleared pipe. It shows what caused the blockage and whether the pipe itself is sound: roots at joints, cracks, a collapsed section, or a belly holding water.
- 5
Flow-test and report
Every affected fixture is run to confirm flow. You get a short written report with stills from the camera and, if there's damage, a fixed quote to repair or reline.


Auger / drain machine
A rotating cable that breaks up or pulls out the obstruction. Right for toilets, sinks and showers. Punches through roots but doesn't remove them.
Hydro jetter
Water at around 4,000 PSI through a nozzle that pulls itself along the pipe. Cuts roots, strips grease and flushes silt. The standard for main lines and stormwater.
CCTV camera + sonde
Shows the inside of the pipe on a monitor. The sonde lets the plumber mark the exact spot and depth of any defect on the surface, so a repair is a small hole, not a trench.
How Block Drains works
We're a marketplace for plumbers and drainers, not a plumbing company. We connect you with a licensed, insured drain plumber who covers your suburb, at one fixed price per job. We take the booking and handle the payment; the plumber does the work, is responsible for it, and is paid per job through us, so there's no incentive to pad the bill and nothing to negotiate at the door.
- 1
Tell us what's wrong
Pick the symptoms (toilet overflowing, sink slow, sewage outside) and your postcode. The site works out the right service and shows the fixed price before you give us a single detail.
- 2
Pick a two-hour window
Choose 'as soon as possible' or a window from 7am to 10pm, seven days. Availability is live: it's based on the plumbers who actually cover your suburb.
- 3
We assign a licensed local plumber
The job goes to the nearest available NSW-licensed drain plumber in our network. You get their name, licence number and ETA by text and email, plus a link to reschedule or cancel.
- 4
The job's done and reported
They clear the drain, put a camera through the line, flow-test everything and leave a short written report. Anything beyond the fixed price is quoted in writing first.
- 5
Your card is charged only when it's done
You save a card when you book; nothing is charged until the plumber marks the job complete. Any extra work is quoted in writing and only charged if you approve it online. Block Drains handles the payment and pays the plumber, so there's never a bill to settle at the door.

Come back for less
10% off every future job, $50 credit for every friend you refer, a discounted annual Drain Care clean, and a free return from the same plumber within 30 days if the drain re-blocks with no damage found.
