Blocked sewer drains
Main-line wastewater blockages, where several fixtures back up at once or an overflow relief gully starts discharging outside.
Relevant when more than one fixture is affected, or waste water is surfacing outside the building.

Blocked Drain Services
Two of the pages below describe methods — the things a plumber does to a drain. Three describe problems — the things a drain does to you. Most people arrive knowing the problem and leave knowing the method.
Start from the problem
If you know what is happening but not why, one of these three pages will match what you are seeing.
Blocked stormwater drains
Rainwater drainage problems — surcharging pits, overflowing downpipes and pooling in the yard during or straight after heavy rain.
Relevant when the problem only appears while it is raining, and no waste water is involved.
Blocked toilets
Fixture-level toilet blockages, and the signs that separate a pan or branch problem from a blockage further down the main drain.
Relevant when a toilet is slow, rising or overflowing — with or without other fixtures affected.
Start from the method
If someone has already told you what they intend to do, these two pages explain what those tools are good at and where they stop being the right answer.
High pressure drain jetting
A water-jetting method that cuts through a blockage and scours build-up off the pipe wall rather than only punching an opening through it.
Relevant when a drain blocks repeatedly, or grease, sediment or root matter is lining the pipe.
CCTV drain inspections
A camera survey that shows the inside of the pipe so the blockage can be located and the pipe condition assessed before any repair decision.
Relevant when a drain keeps blocking, when pipe damage is suspected, or before authorising repair work.
Which page answers your question?
| Page | Method or problem | Covers |
|---|---|---|
| High pressure drain jetting | A clearing method | Build-up lining the pipe, grease, silt, or root matter that needs cutting out rather than pushing aside |
| CCTV drain inspection | A diagnostic method | Finding where a blockage is, and what condition the pipe is in, before deciding what to do about it |
| Blocked sewer drains | A problem type | Several fixtures affected at once, or waste water surfacing outside |
| Blocked stormwater drains | A problem type | Pooling, surcharging pits or overflowing downpipes during rain, with no waste water involved |
| Blocked toilets | A problem type | A toilet that is slow, rising or overflowing — as a fixture problem or as the first sign of a bigger one |
Still not sure which one you need?
That is a normal place to be. Describe what the fixtures are doing and it usually resolves itself in a couple of minutes.
