Where is ABS pipe banned?
The State of California has banned the use of “regrind” or recycled plastic resin for use in ABS drain-waste-vent pipe. The new law stemmed from major problems with pipe failure of recycled-content ABS pipe made by several companies during the 1980s.

ABS is considerably stronger than PVC when exposed to frigid weather, but is also weakened by exposure to sunlight. So much so that many southern states exclusively use PVC.
What is the difference between white PVC and GREY PVC?
The most noticeable difference between regular PVC and electrical PVC is the color of the pipes. PVC pipe that is used for plumbing is usually white while electrical conduit PVC is usually gray. Therefore, Schedule 80 pipes should not be used as an electrical conduit.
What is black PVC called?
Acrylonitrile butadiene styrene (ABS) — Drainage, waste and vent pipes are the usual application for this black pipe material. It’s impact- and heat-resistant, making it ideal for outdoor use. Because many building codes prohibit its use, however, PVC or HDPE pipes are often used instead.
Does PVC have to be fully seated?
PVC pipe is designed to seat neatly into fittings and other pipes to create a tight seal. Water and gas are commonly pumped through PVC pipe, so a properly seated joint is essential.
What is the strongest type of PVC pipe?
Schedule 40 PVC pipe is strong, rigid, and can handle pressure applications. For jobs that require a higher pressurization though, schedule 80 pipe is better suited. Most PVC pipe and fittings have a maximum pressure rating listed so you know what it can handle.
Is there a difference between white and black PVC?
ABS is always black while PVC is white- and easy way to see the difference quickly. PVC piping offers more flexibility, but ABS is a stronger piping and can resist a higher shock.
Is ABS safe for drinking water?

What causes ABS pipe to crack?

Is ABS OK for sewer pipe?
Acrylonitrile butadiene styrene (ABS) and polyvinyl chloride (PVC) are commonly utilized as pipe building materials since they are both non-toxic and abrasion-resistant. ABS is used in drain-waste-vent pipe systems, sewer systems, or electrical cable insulation.
Is ABS pipe always black?
You’ll first notice the difference color – ABS is always black while PVC is commonly white (depending on the type). There’s another main difference in the way that the two types of pipe are installed. PVC pipe is more flexible than ABS, while ABS is a bit stronger and can resist a higher shock or impact.
Can you bury ABS pipe?
ABS pipe may be used in buried or above ground DWV applications. It may be used outdoors if the pipe contains pigments to shield against ultraviolet radiation, or jurisdictions may require the pipe to be painted with water-based latex paint for outdoor use.
Is PBT better than ABS?
PBT is more heat resistant than ABS, and general more resistant to wear. PBT can be mixed with other materials to create unique properties, either in feel or strength. PBT is often used when a product requires chemical or heat resistance or higher levels of stiffness and resistance to impact and weight.
Can I use ABS for a potato gun?
ABS (also see topic #1 on the FAQ page) Regular Applications: Sewage/Drain systems for most modern buildings within confines of foundation, highway safety devices, toys, potato launcher barrels and combustion chambers.
How do you know if plastic is ABS?

What is the GREY PVC pipe called?
Polybutylene pipe is a gray plastic tubing that was commonly used as a water-supply plumbing pipe between 1978 and 1995, at which time it was discontinued due to reports of pipes rupturing. In new construction, it was replaced by copper or more dependable forms of plastic pipe, such as CPVC and PEX.
Can I use GREY PVC for water?
Gray conduit is not rated for pressure pipe applications and may not be suitable for potable water use. Stabilizers and other ingredients used in conduit PVC may be toxic; conduit PVC is not held to the same drinking water standards as NSF marked pipe and should not be used in potable water systems.
