Soil and waste pipes together remove sanitary wastes from buildings. Typically made from unplasticized PVC, the pipes are “welded” together through the use of a chemical solvent that dissolves a small portion of the joining pipe and pipe fittings to fuse them into a solid piece of plastic. Referred to as “DWV” (drain, waste, and vent) pipes, these pipe systems are not pressurized as water intake plumbing systems would be, however most PVC pipes intended for plumbing are specified for and dual-labeled for either purpose. Schedule 40 is most typical. Neither ASTM standards or industry sources limit the composition of PVC for this purpose. The ingredients below are common in PVC piping made in the USA.
