What is a pre-purchase drain inspection?

Some people refer to it as a “pre-purchase drain survey”, while others call it a “home-buyer’s drain survey”. What sets this apart from a CCTV drain inspection, which is typically done to identify and fix a problem, is the mapping of the drain network.

The process involves feeding a high-resolution camera into the system through a nearby access point, such as a manhole or inspection chamber. The process is controlled by a drainage engineer above ground, who feeds the camera through the system – noting any defects, their location, and their size.

Tip: It’s not just people buying a house who stand to benefit. Vendors may want to fix drainage issues at their own expense, speeding up the conveyancing process, and maximising the property’s value at point of sale.
