What is DWV fitting?
DWV Fittings are used for drain, waste and vent applications only. These fittings are not designed or tested to handle pressure. DWV fittings are used most commonly in plumbing applications where a continuous smooth media flow is very important. DWV fittings come as a glue or gasketed system.
What does DWV mean on PVC pipe?

PVC Schedule 40 Pressure/DWV Pipe (drain, waste and vent)
What is the difference between schedule 40 and DWV pipe?
They look pretty similar. They’re both made from the same form of unplasticised PVC (PVC-U) but the difference is in the wall thickness. Schedule 40 PVC pipes are made with thicker walls that stand up to low pressure applications. Whereas PVC DWV piping has thinner walls and is not made for pressurized applications.
What means DWV?
DWV stands for Drain-Waste-Vent. Your home’s Drain-Waste-Vent plumbing system is the collection of pipes that rid your home of sewage and water waste from toilets, bathtubs/showers, sinks and appliances like dishwashers and washing machines.
Is DWV PVC?
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).
Can you use DWV for pressure?
NOT for pressure applications. NOT for compressed air or gasses. 0 (zero) PSI • PVC DWV is NOT a pressure-rated piping system. Recommended test is 10 feet of hydrostatic pressure, which equals 4.3 PSI.
Will DWV fittings work on schedule 40 pipe?
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.
What does NSF DWV mean?
drain, waste and vent applications
Another marking commonly found on pipe and fittings is NSF-DWV. “DWV” stands for drain, waste and vent applications. Products bearing this mark have been reviewed either for disposal of water/wastewater or for venting applications. Products with this marking only should not be used for drinking water applications.
What’s the difference between PVC and DWV fittings?
DWV parts sometimes come threaded, but their slip style fitting ends are called “hubs,” and are usually shallower than the deeper schedule 40 ends. For example a slip coupling may be called “HUB x HUB” or “H x H” for short. DWV parts are made with the same threading (NPT) and are made to the same size as standard PVC fittings.
What’s the name of the slip fitting on DWV pipe?

What is DWV copper pipe?
Copper drainage tube is a seamless copper tube that conforms to the particular dimensions that are commercially known as Copper Drainage Tube, Type DWV. The characteristics of lightweight DWV grade copper tubing make it an excellent, durable choice for use in drain, waste, and vent systems.

The DWV pipe is typically ABS or PVC DWV-rated plastic pipe equipped with a flashing at the roof penetration to prevent rainwater from entering the buildings.
What is a plumbing vent and why do I need It?
Plumbing vents, also known as a vent stack, are an important component of your Drain-Waste-Vent system (DWV): they remove gases and odors from your home, just as your drain pipes carry waste out of your home. All shower, tub, toilet, sink, and floor drains need vents to swiftly move water out of your house and into the municipal or septic system.
