What is the difference between PVC and DWV PVC?
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 is difference between PVC pipe and DWV 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. Instead, DWV pipe and fittings are made to handle a different class of uses – Drain, Waste, and Vent (hence the name DWV).
What is DWV PVC?
Homes built prior to 1960 used galvanized steel or cast-iron pipes for drain/waste/vent (DWV) systems. DWV systems remove wastewater and prevent the flow of sewer gases into homes.

What is the most common DWV material?

Can Schedule 40 PVC be used for sewer?
Schedule 40 is ideal for above-ground vent lines and sewer lines in homes and has a thinner wall thickness than schedules 120 and 80.

The green sewer drain pipe is used for the final underground run from a house to the municipal sewer or septic tank. It is manufactured to be compliant with “ASTM D 3034” standard and is often referred to as “3034” pipe. It is PVC, but a lighter weight than white Schedule 40 DWV (Drain-Waste-Vent) pipe.
What is the best pipe to use for a sewer line?
PVC. The leading choice in residential drain lines over the past four decades, PVC is a light-colored, highly durable plastic that resists the elements and appears to outlast all other piping materials. PVC is made in several different grades: schedules 40 and 80 and chlorinated polyvinyl chloride (CPVC).
How much pressure can DWV PVC take?
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.
What type of PVC pipe is used for drainage?
SDR 35 thick-wall PVC piping is the best material for drainage system piping.
Which pipe is best for sewer line?
PVC is the material of choice for drainage experts, builders and homeowners because of its cost and ease of use. It’s very lightweight and malleable, making it the easiest to install, but it also has a good strength that makes it very durable.
