What is the primary advantage of using ABS piping over PVC?

The primary advantage of using ABS (Acrylonitrile Butadiene Styrene) piping over PVC (Polyvinyl Chloride) is its superior impact resistance. ABS piping is known for its ability to withstand strong impacts and temperature fluctuations without cracking. This durability makes it an excellent choice for various plumbing applications, especially those that may face heavy use or exposure to harsher conditions.

In contrast, while PVC is widely used and has its own advantages, it is generally less impact-resistant than ABS, making it more susceptible to damage from physical impacts. This characteristic of ABS offers an added layer of reliability in systems where pipes may be subjected to stress or accidental impacts, enhancing the overall longevity and performance of the plumbing installations.

Other potential benefits like lighter weight or better insulation properties might not hold true as universally across all contexts, hence they don't serve as the defining advantage of ABS.
