I'm not a plumber but what's the differace between ABS & PVC?

Answer 1

Abs is NEVER used for dynamic (flowing) or static pressure. Both ABS and PVC can be solvent welded; ABS can also be connected with no hub and rubber couplings. ABS is smoother inside so that it will not hinder drainage; it can also withstand higher temperatures associated with showers and kitchen drains. A special type of PVC (CPVC) has the ability to withstand heat and has been used for whole house piping.
PVC comes in a wide range of colors, usually associated with its usage; white is usually used for irrigation because it doesn't have good Ultra violet resistance properties. For above ground irrigation systems as on slopes a tan pvc pipe is used. C900 is green and typically used for medium pressure underground water distribution lines. It can be solvent sealed or gasket sealed.

Answer 2

ABS is the black plastic pipe mostly used for drain, waste and vents (DWV.) ABS is the chemical formula for Acrylonitrile Butadene Styrene. Most common sizes are 1-1/2", 2", 3", 4" and 6" diameters. ABS plumbing systems are generally not for pressurized water.

PVC is a white (or purple) plastic pipe for fresh water. The formulation is Poly Vinyl Chloride. Purple is used to identify non-potable water, such as reclaimed or recycled water for irrigation. Several common PVC pipe diameters are 1/2", 3/4" and 1" diameters, and PVC can be pressurized. See table below.

Answer 3

ABS can be solvent welded. PVC cannot
