37、cted against dirt and damage when stored and transported. They shall be stored according to the manufacturers instructions. 5 General requirements 5.1 General The installation of a wastewater discharge system is divided into the installation of wastewater pipework and the connection of the sanitary
38、appliances. It is essential that the pipework once installed is not disturbed by subsequent construction work or following trades. This requires close co-operation and co-ordination of designer and the installing trades. 5.2 Waste water discharge pipework Wastewater discharge pipework shall to be in
39、stalled according to the design and calculation requirements of EN 12056-2. The design route of the pipework shall be followed. 5.3 Gradient Wastewater discharge pipes shall be installed to the designed gradient and drain completely except where installations are designed to run full bore to dischar
40、ge rainwater in syphonic systems (see EN 12056-3) and the pressure pipework of waste water lifting plants (see EN 120564). 5.4 Sanitary appliance Throughout the building process checks shall be made to ensure that the connection points of the waste water pipework to sanitary appliances and their wat
41、er supply points are correctly sited. 5.5 Safety precautions Information on the location of gas, water supply, electrical power supply, and other services shall be made available in order to ensure that the wastewater installation can proceed and be used safely. 5.6 Stability of sanitary pipework Sa
42、nitary pipework is not part of the load bearing structure. There shall be no unauthorized attachments to the drainage system. Pipework shall be supported. The loads that will be exerted by the sanitary appliances and drainage system in operation shall be taken into account when designing the support
43、 system.

Fixings appropriate to the pipe material and the supporting structure shall be i
44、nstalled in accordance with the manufacturers recommendations. 6.2 Jointing The jointing of wastewater discharge pipes and fittings shall be made water and gas tight according to the manufacturers instructions using specified sealing techniques. 6.3 Fixing and supporting Pipelines with joints, which
45、 allow longitudinal movement, shall be fixed and/or supported in such a way as to ensure that during service the joint cannot become unintentionally disconnected. Reaction forces shall be considered. 6.4 Changes of directions and branch pipe connections Any change of direction in pipelines or branch
46、 pipe connections shall be made using fittings. 6.5 Connection of pipes of different materials and sizes The connection of pipes of different materials and/or sizes shall only be made with purpose made fittings. 6.6 Thermal movement Thermal movement shall be considered. The pipe manufacturers instru
47、ctions shall be followed. 6.7 Installation in concrete or other fills If wastewater discharge pipelines are installed in concrete or other fill, the manufacturers instructions shall be followed. Pipelines and pipe joints shall be protected against ingress of the surrounding fill material and be rest
48、rained from displacement due to flotation. 7 Installation of sanitary appliances 7.1 Fixing Sanitary appliances shall be safely and securely fixed to the structure, using fixings and techniques recommended by the manufacturer. 7.2 Connection The sanitary appliance shall be connected to the wastewate
49、r discharge pipe by using the manufacturers recommended fitting. If necessary the connecting fitting shall be supported.
