Why we need a plan of your sewer pipes

Generally, when sewer pipes and drains are installed by a licensed plumber, they are inspected by an authorised person who draws a plan of the drainage installation showing where the drains run, what plumbing fixtures are connected and what, if any, other properties are connected.

Currently, we have a self inspection system where the plumber draws the drainage installation and submits the drawing to the local water authority or council for their records.

Owners can get a copy of this diagram from their local water authority or council. If your property has a history of blocked drains or is surrounded by trees, I strongly suggest you have a copy of this drainage diagram and keep it in a safe and easily accessible place.

Your local plumber can assist with getting a copy of this drainage diagram.

In NSW Australia, a drainage diagram is a standard inclusion in a Contract of Sale for any property. I suggest you look there first!
