The Standard is about installing new domestic water services. This can apply to pipes with internal diameters up to 50mm.
This involves interpreting material requirements, producing and securing assemblies and any required insulation and liaising with plumbers. Assembly methods and techniques can include cutting, electrofusion welding, drilling and tapping or mechanical jointing on metallic or polyethylene (PE) materials or barrier pipes.
This Standard is for water network operatives who assemble pipes and fittings for new domestic services.
