The Differences Between ABS and PVC Pipes

Before starting a plumbing project, it is important to understand your options on piping materials.  Two types of plastic piping commonly used in homes today are Acrylonitrile Butadiene Styrene (ABS) and Poly Vinyl Chloride (PVC). Always check your local building codes to make sure you are aware of and following the regulations.

There are several differences between ABS and PVC pipes. The main difference is that ABS pipes contain BPA (Bisphenol A), a chemical used in many types of plastic. ABS is black in color, while PVC is white.  The difference in color makes them easy to identify. PVC piping is usually softer and more flexible by the addition of plasticizers, but ABS is stronger and more durable to shock.  ABS may be the better choice for underground plumbing as it can handle extreme cold. Direct sunlight can cause ABS to warp. PVC may be the better choice for inside your home as it can muffle sound. ABS pipes are a one-step installation process connected through special cement.  PVC piping must be primed first before cementing. Due to the extra step in using PVC, choosing to go with ABS may reduce labor costs.  

Both ABS and PVC pipes are used in plumbing because they are non-toxic and resistant to abrasion, chemicals, and water degradation. Both types are resistant to most acids, alkalis, and salts.  As for disposal, neither ABS nor PVC is biodegradable.
