Cellular core PVC pipe can now be installed in residential buildings for DWV applications that contain one or two dwelling units, or for row houses that don’t exceed three storeys tall.Edmonton, Alta—Albertans will now be able to use cellular core PVC pipe in residential buildings. This variance applies to buildings that contain one or two dwelling units, and row houses that do not exceed three storeys in height.
A STANDATA refers to a province-wide variance, interpretation or information bulletin related to safety codes and standards, which is issued by the Public Safety Division of Municipal Affairs in Alberta.
The variance recognizes the National Plumbing Code of Canada 2020 and will include cellular core PVC pipe and fittings that conform to ASTM F 3128-19, PVC schedule 40 drain, waste, and vent (DWV) pipe with a cellular core for use with PVC and CPVC drain, waste, vent pipe and pipe fittings requirements.
According to the STANDATA, industry stakeholders wanted an option to use cellular core PVC pipe for DWV applications due to plastic drainage supply shortages when limited availability of base materials occurs. This also comes in advance of proposed changes for the next version of the National Plumbing Code of Canada, which is due to be released in late 2021.
This variance is applicable throughout Alberta and expires on Feb. 1, 2023.
