2014年7月18日 · 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.

2025年1月2日 · DWV PVC pipe: The design standards of DWV piping systems focus on wastewater discharge and air circulation, and the pipes must meet specific slope requirements to ensure smooth flow of sewage. In addition, DWV PVC pipes are also required to have lower pressure bearing capacity because they are mainly used in non-pressure systems.

What is the difference between DWV and PVC pipes? DWV can easily be mistaken for PVC because they look remarkably similar. However, there is a big difference. DWV is not able to be used with pressure. It is strictly to be used for draining and venting purposes. The joints or “Hubs” are not as deep, and the pipe will typically be thinner.

2023年9月18日 · PVC stands for polyvinyl chloride and is commonly used for applications where water or chemicals need to be transported. It is lightweight, durable, and resistant to corrosion and chemicals. On the other hand, DWV stands for drain, waste, and vent and is typically used for the removal of wastewater from buildings.

PVC DWV pipe is a lightweight polyvinyl chloride pipe that has thinner walls than schedule 40 PVC pipes, and therefore should only be used in non-pressurized applications. DWV pipe is specifically for drainage, waste and venting purposes, but can be used in various other household applications, too.
