Stiffness Class (SN) Rating: Marley PVC DWV pipe system is manufactured to different pipe stiffness classes to suit the performance requirements of the installation.
SN4 and SN6 – These pipes are considered suitable for all domestic plumbing and drainage for domestic and residential housings in 100 and 150mm sizing.
SN8 and SN10 – Is suitable for general drainage and commercial installation where higher pipe stiffness is required to provide minimum deflection of installed pipes, due to imposed loads from backfill or to assist with poor bedding practices and materials.
SN16 and Greater-Territorial Authority – This pipe is designed to meet the requirements of the Territorial Authority where very high long term stiffness is required to provide minimal ovality due to high imposed traffic loads.
