How To Find a Drain Inspection Opening




Recently we went to a blocked drain that was arguably not the owner's responsibility. Because an inspection opening was not accessible at the boundary, it was impossible to determine whether the blockage was the owner's or outside the property, becoming Taswater's responsibility.

In the case of a blocked drain, An  inspection opening easily accessible to the surface at your property boundary will assist you by;

determining whether a blocked drain is located on your property or outside the property in Taswater's infrastructure.

Unable to determine the location of the blockage by accessing the Inspection opening, the owner had to pay for the drain clean.

A sewer inspection opening or "IO" is typically identified by a  PVC round lid approximately 100mm in diameter. Usually found at the boundary's lowest point, on a bathroom drain inside the house, or at the base of a stack on multiple-story homes. 

If you cannot locate your sewer inspection opening to the surface on your property, we recommend the following:

Contact King Plumbing to undertake a site inspection and drain camera inspection and locator.

If we cannot locate the "IO", we access Taswater's infrastructure drawings for your property to find your sewer connection.

Once we access Taswaters infrastructure drawings and the as-constructed drawings submitted to the council, we will locate the sewer connection point on your property and present you with options for having a sewer inspection opening to the surface installed.
