Background  \nA drainage plumbing diagram (DPD) is a diagrammatic representation of drainage plumbing work within a property. They were known previously as ‘as-constructed diagrams’,‘as-cons’or ‘flimsies.’  \nDrainage plumbing diagrams are regularly used by homeowners, licensed plumbing contractors and others to determine the layout of drainage plumbing on a property.  \nKnowing the layout of drainage plumbing can assist in:  \n• identifying where additional connections to existing drainage plumbing can be made;  \n• locating drainage connection points for survey-strata lots;  \n• ensuring that new buildings or extensions do not interfere with existing drainage plumbing;  \n• ensuring that any excavation works do not disturb the drainage plumbing;  \n• the repair of drainage pipework; and  \n• clearing blocked drains.  \n2. Submitting drainage plumbing diagrams  \nLicensed plumbing contractors are required to submit a drainage plumbing diagram when they are the responsible person for drainage plumbing work that involves the installation, alteration or extension of drainage plumbing including drainage plumbing services for survey-strata lots. A penalty may be applied for failing to provide a compliant drainage plumbing diagram.  \nThe drainage plumbing diagram must be submitted to the Plumbers Licensing Board (the Board) with the related certificate of compliance within 5 working days after the work is completed.  \nHint:  \nDrainage plumbing is any pipework installed below ground and therefore needs to be shown on a drainage plumbing diagram. This includes pipework to floor waste gullies, disconnector and overflow relief gullies and trade waste traps.  \nWhere a drainage plumbing diagram is not lodged, the Board may request the licensed plumbing contractor responsible for the work provide the drainage plumbing diagram.  \nThe licensed plumbing contractor is required to provide a copy of the certificate of compliance to the property owner. It is considered good practice to provide a copy of the drainage plumbing diagram to the owner at the same time.  \nWhen installing drainage plumbing for the purposes of providing connection points to surveystrata lots, a copy of the drainage plumbing diagram must be provided to the property owner or occupier. Licensed plumbing contractors may also retain a copy for their own records.  \n3. Information to be included on drainage plumbing diagrams  \nThere are minimum requirements that apply to drainage plumbing diagrams","cbCaikXBJ7ePT6NW","https://ap.wps.com/l/cbCaikXBJ7ePT6NW","pdf",612863,"English","# 1.
