Sewage overflowing or backing up

Blocked sewer FAQs
Still not sure what you are dealing with? A licensed plumber will talk it through with you, any hour.
How much does it cost to clear a blocked sewer in Sydney?
It depends on how deep the blockage is and how far along the line it sits. You get one fixed price after the plumber has looked, before any work starts, and there is nothing to pay just for us to come and look during business hours. A 0% interest payment plan is available if the camera finds a pipe that needs repair.
What are the signs of a blocked sewer rather than a blocked drain?
A blocked sewer affects the whole house: more than one drain slow at once, the toilet gurgling when the shower runs, waste rising in the lowest floor waste, water spilling from the gully outside, a sewage smell in the yard, or a wet patch on the lawn. One slow basin on its own is usually a local blockage. Our guide on how to unblock a drain explains when to stop and call.
Is the blockage my responsibility or Sydney Water's?
Under Sydney Water's published policy the property owner is responsible for the private sewer from the house all the way to the point of connection with the Sydney Water main, including that connection and any tree roots growing into it, even where it runs under the footpath. Sydney Water owns the main and the junction on it, and takes over a repair only if the junction itself has failed or the connection is deeper than 2.5 metres. If the camera shows the fault is in the main or the junction we tell you and Sydney Water is notified, so you are not paying for work that is not yours. Our guide you or Sydney Water: who is responsible sets out the full boundary.
What causes blocked sewers in Sydney?
Tree roots growing into the joints of old clay lines, wet wipes and other things that should never have been flushed, fat and grease setting hard, and pipes that have cracked, sagged or collapsed with age or ground movement. The camera check after the clear shows you which one it was.
Do root-killer chemicals work on a blocked sewer?
Not on a line that is already blocked. Chemicals sit on top of the blockage, and on older pipes they eat the joints and turn a clearing job into a repair. Roots have to be cut out with the jet blaster, and the entry point found on camera, or they grow straight back.
How do you prove the sewer is actually clear?
We run a CCTV camera through the line after the jet blaster, free with any booked drain service. You see the pipe on the screen: the cause of the blockage, the condition of the pipe and clear water flowing to the boundary. If there is damage, it is on the footage and you get a fixed price to fix it.
Is a blocked sewer an emergency?
It is when sewage is overflowing outside, backing up inside, or more than one fixture is overflowing at once. Raw sewage is a health risk, so stop running water and call. We run emergency sewer unblocking 24/7 across Sydney. After-hours and weekend call-outs may attract a fee at our discretion, and we always confirm that with you before we attend.
Can a blocked sewer be fixed without digging up the yard?
Often, yes. Clearing is done through the existing inspection openings, and a cracked or root-damaged section can usually be relined from inside the pipe without excavation. Digging is kept for a collapsed section the camera shows cannot be relined, and you know which blocked sewer repair you need before anyone picks up a shovel.
How can I prevent sewer blockages?
Keep wet wipes, sanitary products and nappies out of the toilet even when the packet says flushable, never pour cooking oil or grease down the sink, and if you have big trees near the sewer line, have it checked on camera before the roots block it again.
