Plumbing rough-in

Photo of a wall frame with plumbing roughed in.All plumbers must be registered with the appropriate water and sewerage authority. All their work has to be inspected, approved and issued with a compliance certificate guaranteeing their work.

All internal water and gas pipes run through the building to their designated locations. Ensure that plumbers do not cut excessively deep notches into studs or other load bearing members when running pipe work. Excessively notched members should be replaced or repaired with additional back blocking.

All pipes should be properly clipped to the frame to avoid water hammer and pipe vibration. All plumbing fixtures should be adequately attached to the frame.

Check for leaks before installing internal linings.
