A blocked drain plumber is who you need when water won’t go down, the toilet backs up or the gully outside starts overflowing. SuperFox passes your enquiry to one independent local plumber who handles blocked drains, and they call you back within 24–48 hours to work out the cause and quote the fix. If sewage is overflowing, choose Urgent on the form.
What are the signs of a blocked drain?
The earlier you act, the simpler the fix usually is. Watch for:
- Sinks, showers or baths draining slowly
- Gurgling from plugholes or the toilet when another fixture drains
- Toilet water rising high before it slowly drops
- Bad smells from drains or around the yard
- Water pooling or bubbling at the overflow relief gully (the grated outlet outside)
- Damp, sunken or unusually green patches of lawn over the sewer line
One slow sink is often a local build-up of hair, soap or grease. Several fixtures playing up at once points to a blockage further down the main drain. Our guide to the best way to unblock a drain covers safe first steps, like clearing the strainer and using a plunger.
What does a blocked drain plumber do?
The plumber starts by finding where the blockage is and what’s causing it, then chooses the right method to clear it.
Diagnosis. The plumber asks which fixtures are affected, checks the overflow gully and inspection openings, and often runs a drain camera inspection. The camera shows whether the problem is roots, a build-up of grease or wipes, a foreign object, or a cracked or collapsed pipe.
Clearing. Depending on the cause, the plumber may use:
| Method | What it’s used for |
|---|---|
| Plunger or hand auger | Simple blockages close to the fixture |
| Electric drain machine (eel) | Roots and stubborn blockages further down the line |
| Hydro jetting | High-pressure water to cut roots and flush out grease and silt |
| Drain camera inspection | Finding the cause and location, and checking the result |
| Pipe repair or relining | Cracked, displaced or collapsed sections |
Follow-up. Once the drain is flowing, the plumber may recommend a camera check to confirm the pipe is in good condition, or repairs if roots will keep coming back. Clearing a blocked drain doesn’t usually need a certificate of compliance, but some repair work on drains may, so ask.
Why are blocked drains so common in Adelaide?
Adelaide has a few local factors that make blockages more likely.
Old clay sewer pipes. Many homes built before the 1980s have terracotta pipes joined with mortar or rubber rings. Over time the joints loosen and tree roots find their way in, chasing moisture. Roots are the most common cause of recurring blockages in older suburbs. Our guide to tree roots in pipes explains the signs and long-term fixes. If a tree is the problem, Tree Fox can help with the tree side.
Reactive clay soils. Large parts of Adelaide sit on clay that swells in winter and shrinks in summer. That movement can crack pipes and push joints out of line, creating a lip where waste catches.
Hills properties. In the Adelaide Hills, many homes drain to a septic tank or a community wastewater management system (CWMS) rather than the mains sewer. A blockage can be in the house drain, the tank or the outlet, so tell the plumber what system you have.
Whose pipe is it? Drains on your property are generally the owner’s responsibility, while SA Water looks after its sewer mains. If neighbours have the same problem or the overflow is in the street, call SA Water on 1300 729 283.
Blocked toilet: what can you do first?
Stop flushing, as each flush adds water to a pipe that can’t drain. Try a plunger with a good seal for a minute or two. If it doesn’t clear, or other fixtures are also slow, the blockage is likely in the main drain and it’s time for a plumber. Wet wipes, sanitary products and paper towel are common culprits, even when the packet says “flushable”. For a toilet that keeps running rather than blocking, see taps and toilets.
What affects the price of clearing a blocked drain?
Every job is different, so the plumber quotes once they understand it. The main factors are:
| Factor | Why it matters |
|---|---|
| Location of the blockage | Close to the fixture is quicker than deep in the main line |
| Cause | Grease is easier to shift than established tree roots |
| Access | Hidden or buried inspection openings take time to find and open |
| Method | Camera inspection and hydro jetting use specialised equipment |
| Pipe condition | Cracked or collapsed pipes need repair, not just clearing |
| Time of day | After-hours call-outs usually cost more |
Ask the plumber how they charge, including any call-out fee, and whether a camera inspection is included.
Blocked drains in SA: what to ask the plumber
Plumbing and drainage work in South Australia must be done by a licensed plumber, and you can check a licence on the Consumer and Business Services (CBS) public register. Before work starts, ask:
- Can you show me the camera footage of the problem?
- Will clearing fix it, or is there damage that will cause it to block again?
- Does any repair work need a certificate of compliance?
- If roots are the cause, what are the long-term options?
