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).
Similarly, Is DWV cheaper than PVC?
PVC DWV: Have thinner walls. Because of this they are less expensive than schedule 40 PVC.
Additionally, What are the different types of PVC?
There are four types of PVC pipes:
- Unplasticized PVC (PVC-U)
- Chlorinated PVC (C-PVC)
- Molecular oriented PVC (PVC-O)
- High Impact PVC (PVC-Hi)
Are there different types of PVC pipe?
There are two main types of PVC pipe, schedule 40 and schedule 80. What makes them different is the thickness of the pipe walls. A rule of thumb when it comes to PVC pipes is that the higher the number, the thicker it is. For instance, of the two, schedule 80 has thicker walls when compared to schedule 40.
Can you glue DWV to PVC?
You can use a no-hub coupling–the rubber sleeve with 2 hose clamps. These come in slight variations depending on the materials they are intended to join, so make sure to get the right one.
Can DWV pipe be used for drinking water?
DWV piping is not suitable for potable water.
Can I use Schedule 40 PVC for sink drain?
Ninety-nine percent of drain lines under sinks are bound to leak sooner or later. … He uses thick “schedule 40” plastic (PVC or ABS) parts that are “welded” together with solvent cement for sink drain plumbing. An assembly like this will last forever, no matter how times you bash it with the wastebasket.
Can Schedule 40 PVC be used for sewer?
There’re different wall thicknesses (schedules) of PVC pipe. … 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.
How many types of PVC plastic are there?
PVC is produced in two general forms: a rigid or unplasticized polymer (RPVC or uPVC), and the second as a flexible plastic.
Which is stronger PVC or CPVC?
Differences in Pipe Strength
Both materials are very strong, but CPVC is harder than PVC, which makes it more prone to breaking. CPVC is more brittle than PVC and can be warped or cracked more easily, but it is also more flexible than PVC.
What are the four categories of PVC pipe?
There are four types of PVC pipes which are commonly used, unplasticised PVC (PVC-U), modified PVC (PVC-M), chlorinated PVC (PVC-C) and molecular oriented PVC (PVC-O). PVC-U pipes and fittings are used in the transportation of drinking water, soil and waste, sewage, underground drainage and industrial applications.
What do the different colors of PVC pipe mean?
Blue pipes are used for potable or drinking water. Green pipes are sewer and drain lines. Lavender or purple pipes carry reclaimed wastewater that undergoes filtration and disinfection treatment before being reused for irrigation.

What type of pipe is safe for drinking water?
Copper pipes with lead-free joint materials are the best choice for water pipes. They are long-lasting and won’t leach chemicals into your drinking water. However, copper pipes are generally more expensive, and copper’s intensive extraction and manufacturing process presents some environmental trade-offs.
Which PVC pipe is safe for drinking water?
Plastic pipe such as PVC (polyvinyl chloride, used for cold water only), and CPVC (chlorinated polyvinyl chloride, used for both hot and cold water) have been around for years, and both are approved for use with drinking water.
Is DWV pipe Food Safe?
This type of PVC is food safe, so it will not harm any fish or plants that it comes into contact with. In fact, it’s ideal to use when building vertical aquaponics systems, growing strawberries, or separating shrimp from fish in an aquaponics system.
Can I use PVC for sink drain?
PVC is a favored piping material among homebuilders because of its rust-proof texture and infinite durability. However, PVC is not suitable for incoming water flow — its use is limited to toilet and drain piping due to the plastic’s lack of heat tolerance.
Can I use PVC for kitchen sink drain?
For kitchen drains, generally, PVC pipes are preferable to metal pipes as PVC pipes don’t corrode. The installation process of PVC pipe under the kitchen sink is not very tough.
Can you use PVC under sink?

What schedule PVC is used for sewer line?
Schedule 40 PVC pipe is the standard strength/thickness pipe used in most household sewer lines.
What type of PVC is used for sewer lines?
PVC is made in several different grades: schedules 40 and 80 and chlorinated polyvinyl chloride (CPVC). Their uses are as follows: Schedule 40 is most commonly used for drain-line piping under houses.
Can you use PVC for sewer line?
Uses for PVC Pipes
Regular schedule 40 PVC pipe (here) is perfect for drains and wastewater. Like ABS pipe, PVC pipe is used for drain, waste, and vent piping systems and as insulation for electrical cables. It’s versatile and durable and the choice for professionals and DIYers alike.
