Homeowners are generally responsible for private sewer pipes within their property boundary, while the local water authority may be responsible for blockages in the main sewer network. In Sydney, Sydney Water is typically responsible for wastewater pipes outside the property connection point.
IIf you have a blocked drain, it’s best to contact a licensed plumber with experience in drain diagnostics and repairs. Antons Plumbing & Gas is a local Thornleigh plumbing company equipped to inspect, clear, and repair blocked drains safely and in line with NSW standards.
A badly blocked drain should usually be inspected and cleared by a licensed plumber, especially if water is backing up, smells are coming from the drain, or multiple fixtures are affected.

Avoid using harsh chemical drain cleaners, as they can damage pipes and may not fix the main cause.
