100mm SN6 solid-wall PVC DWV pipe for drain, waste and vent systems. Join to compatible DWV fittings using priming fluid and Type N solvent cement.
SN describes pipe stiffness, or resistance to deformation under external loads. A higher SN indicates greater stiffness. It is not a pressure rating. Standard sizes below 100mm are specified by wall thickness.
Nominal size identifies the pipe size and matching fittings. It is not the exact internal or outside diameter. For example, 100mm DWV pipe has an outside diameter of approximately 110mm. DWV and pressure pipe of the same nominal size can have different outside diameters.
Use DWV fittings matched to the pipe size. For solvent-weld joints, cut the pipe square, remove burrs, clean and prime the joint surfaces, then apply Type N solvent cement and assemble as directed in the jointing guide. Allow the joint to cure before testing or use.
Above-ground pipework needs suitable support. Below-ground installations need prepared bedding, side support and backfill suited to the site and loading conditions. Follow the installation guide and the requirements for the installation.
