PVC DWV Pipe

DWV pipes are designed for non-pressure waste water and sewer applications and are supplied with either a rubber ring or solvent weld joint system.

Pipes up to DN80 are classified by minimum wall thickness and pipes DN100 and greater are classified by stiffness (SN rating).

SN4 and SN6 are generally used for plumbing and domestic applications, whereas the higher SN8 and SN10 rated pipes are used for municipal drainage and sewerage reticulation applications. The requirements of national codes and local authority standards will determine the pipe class and jointing system to be used.
