System 15 is designed for the majority of low-rise and light commercial applications where DWV systems don't run through air plenums. CSA certified Schedule 40 pipe and fittings connect fast and easily using solvent cement. System 15 won't rust, pit, scale or degrade, even under continued exposure to moisture, salts, aggressive soils and most acids. Interior and exterior walls remain smooth, ensuring years of reliable, maintenance-free flow. Grey colour PVC and System 15 labels on all fittings provides easy identification of the DWV system.
