Specification:If you've been in the market for PVC pipe and fittings you may have come across something called DWV. DWV parts look very similar to standard white schedule 40 PVC pipe and fittings. The only real difference is that DWV PVC is not made to handle pressurized uses like schedule 40 parts are. Instead, DWV pipe and fittings are made to handle a different class of uses – Drain, Waste, and Vent (hence the name DWV). Drain, waste, and vent applications use gravity to create the flow of water and waste through the pipe line. These applications cause minimal stress on the PVC parts, allowing for thinner walls and the elimination of pressure testing by the manufacturer.

Scope: 

Do not store pipe and fittings in direct sunlight for long periods. Store pipe in such a manner as to prevent sagging or bending.

This specification covers PVC DWV ASTM D2665 Drainage applications. This system is Intended for drainage applications where the operating temperature will not exceed 140°F.

Fields of application: 

Piping networks for drainage in building.

Piping networks for piping system in water treatment plant.
